So please, take a few minutes to fill out the warranty registration card, and drop it in the mail. 7 Unpacking and Placement unpacking the digital surround decoder Unpack your Digital Surround Decoder and remove all accessories from the carton. Important! Keep all packing materials for future transport of your Digital Surround Decoder. Shipping your new component in anything other than its purpose-designed packing material may result in damage that is not covered by the warranty. re-labeling your PAV remote control The PAV/PDSD system uses the PAV remote control, but offers many new features and capabilities. Included with your PDSD is a new label for your remote control that reflects some of these new features. It is best to remove the original label and then replace it with the new one: · use a hairdrier to warm and loosen the adhesive holding original label in place · remove the label by prying a corner up and pulling gently · remove any residual glue from the remote with a little alcohol applied to a soft cloth · peel off the protective backing on the new label and carefully install it on the remote, keeping its holes reasonably centered on their corresponding buttons · teach the remote control its new commands (only the buttons to the right of the numeric keypad are affected; see teach ir commands to your remote, pp. 57-58) Alternatively, your dealer may teach your remote control its new commands from the remote control they use in their showroom. This option avoids having to use the menu system in the PAV/PDSD system, if you are new to the menu system and simply wish to start using the system. Caution: Your Proceed remote control also contains a lithium battery that maintains its memory in the absence of the alkaline batteries. Installing a replacement lithium battery incorrectly may result in damage to the remote control and/or explosion of the battery. We recommend this be performed by the dealer. This lithium battery must be replaced only with the same or equivalent type, and must be installed properly. Discard used batteries according to the battery manufacturer's instructions. 8 placement Place the Digital Surround Decoder near the digital sources, thus keeping interconnecting cables reasonably short. It may be placed on a shelf or in a cabinet where it's convenient to operate. Note that adequate clearance for the AC cord and connecting cables must be left behind the Digital Surround Decoder. We suggest leaving at least three inches of free space behind the Digital Surround Decoder to allow all cables sufficient room to bend without crimping or undue strain. ventilation It is normal for your Digital Surround Decoder to run quite warm. Be sure to allow 2 to 3 inches of clearance above it to allow heat dissipation through air circulation. The vents on both the bottom and the top of the Digital Surround Decoder must be kept free from any obstruction which would reduce the flow of air through the unit. Avoid placement on soft surfaces that would restrict airflow (such as carpeting). If your PDSD becomes too warm, it will display an on screen message to that effect. If the temperature continues to rise, the unit will eventually protect itself by shutting itself off. This eventuality is extremely unlikely unless its surrounding ambient temperature is uncomfortably hot for people (as well as electronics). An internal, temperature-controlled cooling fan kit may be ordered from Madrigal if you do see the on screen warnings about excessive temperatures, and if improving the available ventilation in the installation would be difficult. Contact your dealer or distributor for more information. Drawings are included in this manual to facilitate special installations and custom cabinetry (see Dimensions). The serial number for your Digital Surround Decoder is found on the bottom of the unit. Please note and record this number for your future reference. serial number label WARNING: BEFORE ATTEMPTING TO OPERATE THIS DEVICE, REFER TO OWNER'S MANUAL FOR PROPER OPERATING INSTRUCTIONS AND SAFETY PRECAUTIONS.

In the U.S. and Canada, registering your purchase also automatically extends your warranty from 90 days to five years. It will take only a minute or so. Please complete the card now, before you forget. 9 Operating Voltage & Frequency The Digital Surround Decoder is set at the factory (internally) for 100V 120V , , 220V 230V, or 240V and either 50 or 60 Hz AC mains operation, as appropriate , for the country in which it is to be sold. (230V/50Hz only in European Union countries, in compliance with CE regulations.) Neither the voltage nor the line frequency setting may be changed by the user. Make sure that the label on the rear panel of the Digital Surround Decoder (above the AC input receptacle) indicates the correct AC operating voltage for your location. Attempting to operate the Digital Surround Decoder at an incorrect voltage can damage the unit. Warning: Neither the voltage nor the line frequency settings of your Digital Surround Decoder may be changed by the user. There are no user-serviceable parts within the unit. Please refer any problems to an authorized Proceed service center. If the AC mains voltage or frequency indicated on your Digital Surround Decoder is incorrect, please contact your local, authorized Proceed dealer or distributor. The Digital Surround Decoder can easily be powered by a normal 15-ampere AC mains line. If other devices are also powered from the same AC line, their additional power consumption should be taken into account. warm up/break-in period Although your Proceed Digital Surround Decoder delivers outstanding performance straight out of the box, you should expect to hear it continue to improve as it reaches its normal operating temperatures and its various components "break-in." It has been our experience that the greatest changes occur within the first 300 hours as the PDSD reaches thermal equilibrium and the capacitors fully form. After this initial break-in period, the performance of your new product should remain quite consistent for years to come. The only exception to this rule is if power is removed from the unit for an extended period of time, allowing it to cool down. Depending on the degree of cooling involved, you should expect a brief warm-up period before the Digital Surround Decoder's sound quality is at its best. Unless your Digital Surround Decoder was allowed to become quite chilled, subsequent thermal re-stabilization should not take long. 10 A Word About Installation Every effort has been made to make the Proceed PAV/PDSD system simple and straightforward to install and use. We know of no other product which offers this level of performance and flexibility. Still, we have no way to evaluate many other variables such as the size and shape of your room, its acoustics, and the associated equipment you have chosen to use with your PAV/PDSD. All of these factors influence the ultimate performance of your system. Moreover, the PAV/PDSD incorporates many system-specific adjustments which enhance its performance with the widest possible range of associated components. For this reason, we strongly encourage you to have your system installed and calibrated by your dealer, whose experience, training, and specialized equipment can make a profound difference in the final performance of the system. The PAV/PDSD features the ability to "remember" the carefully calibrated settings chosen by your installer. Y may adjust any or all of these settings to suit your ou taste for a particular recording, either from the front panel or from the remote control. When you want to return to the calibrated settings (which most accurately reproduce the widest variety of program material), simply press recall on the remote control or on the front panel. 11 A Quick Start For CD The PAV/PDSD is an exciting system, and we understand that many owners will be anxious to get it up and running as quickly as possible. What follows is not a replacement for a complete setup of the system. Rather, it is provided so you can get some music playing from a single digital source as quickly as possible. It assumes that your system is already set up in other respects (speakers connected to power amps, etc.). Once done, please read up on how to do a complete setup and calibration in order to get the most from your investment (or have your dealer/installer do it for you). 1 MAKE THE PHYSICAL CONNECTIONS; TURN EVERYTHING ON Connect the Communications Cable between the PAV and the PDSD; connect the outputs of the PDSD to your power amplifiers, as indicated (front, rear, center, sub); connect a CD transport to any matching digital input connector on the PDSD, noting which connector you use; ensure that the main video output of the PAV is connected to your television (so you can see the on screen menus). Once this is done, turn on all the components involved (CD transport, PAV PDSD, television, amplifiers). Turn the amps on last (al, ways a good habit with any audio system). 2 PRESS AND HOLD THE CD1 BUTTON ON THE FRONT OF THE PAV This shortcut of pressing and holding an input button will take you directly to the define button menu for that button. 3 TELL THE SYSTEM WHICH CONNECTOR YOU USED FOR YOUR CD TRANSPORT IN STEP 1 We have no way of knowing what sort of digital interface your particular CD transport might use (AES/EBU? RCA? BNC? EIA-J?), but logically, you'd like to be able to use your main CD player with the button labeled cd1. This step allows you to use whatever connector you need to use in conjunction with the button you'd like to use. Using the volume +/­ buttons, move the arrow cursor down to the line that defines your first audio connection (1: Digital, Dig 1) and press enter. Then move the arrow cursor down (volume +/­) to the line that defines which connector is being used, and press enter again. With the cursor changed to an x instead of an arrow, the volume +/­ buttons will allow you to select whatever digital input connector you used in Step 1. When done, press enter again to save your change. 4 PRESS MENU TO EXIT THE MENU SYSTEM, AND ENJOY Make sure the volume is on at a low level before you fire up your CD player, press the cd1 button, and raise the volume to a comfortable level. According to the factory defaults (which you can easily change), cd1 is preset to come on in 2-channel/surround off. Y should properly calibrate the ou system so all speakers are playing at the proper volumes before you listen critically to multichannel audio. Performing this calibration only takes only a few more minutes, but you should read up on it a bit first. Y can enjoy ou the PAV/PDSD system in regular stereo until then. 12 A Quick Start For Laserdisc Okay, so now you have some music to listen to while reading the manual. But you're in a rush to hear Dolby Digital on your new system. Remember: What follows is not a replacement for a complete setup of the system. We will assume here that you have already done the CD setup on the previous page. To get a laserdisc player playing: 1 MAKE THE PHYSICAL CONNECTIONS If you have a Dolby Digital (AC-3) output on your laserdisc player and the RF Demodulator card in the PDSD, connect the AC-3 output to digital input 1 on the PDSD. Also connect the (normal) digital output of your LD 1 to any matching digital input on the PDSD, noting which one you use. Connect the analog outputs of the LD to the laserdisc inputs of the PAV. Finally, don't forget to connect the video output of your laserdisc player to the corresponding input on the PAV Turn everything on. . 2 PRESS AND HOLD THE LASERDISC BUTTON ON THE PAV This shortcut of pressing and holding an input button will take you directly to the Define Button menu for that button. 3 TELL THE SYSTEM WHICH CONNECTORS YOU USED FOR YOUR LASERDISC PLAYER IN STEP 1 Using the volume +/­ buttons, move the arrow cursor down to the line that defines your video connection and press enter. Confirm that the video is connected to the laserdisc connector, and whether you used composite or S-video connections. Press enter to save any changes you might need to make, and then press menu to return to the previous menu. Similarly, set up all three audio connections: move the arrow cursor down (volume +/­) to the line that defines your first choice, and press enter again. With the cursor changed to an x instead of an arrow, the volume +/­ buttons will allow you to select digital input 1 RF (for example). When 1 done, press enter again to save your change, and move on to your second choice (a digital input); then your third choice (the analog connection), saving changes as you go. This hierarchy allows the system to automatically select the best available signal, by associating up to three different connections with a single button on the front panel of the PAV. 4 PRESS MENU TO EXIT THE MENU SYSTEM, AND ENJOY Make sure the volume is on at a low level before you fire up your laserdisc player; press the laserdisc button once, and raise the volume to a moderate/ comfortable level. Important: you should properly calibrate the system so all speakers are playing at the proper volumes before you listen critically to multichannel audio. Performing this calibration only takes only a few more minutes, but you should read up on it first. Please review the chapter on The Setup Menu for more information, pp. 39-55. 13 Special Design Features Congratulations on your purchase of the Proceed Digital Surround Decoder (PDSD). We have gone to great lengths to ensure that the PDSD remains "future-proof" even in these times of change. As a result, you will be able to enjoy the outstanding performance of the Digital Surround Decoder for many years. In case you are interested in technical details, what follows is a brief outline of some of the key technologies in your new product. hardware upgradable The Digital Surround Decoder employs a ten slot backplane configuration. This means that various combinations of up to ten "cards" can be inserted into the back of the unit, and that they will all communicate with each other as needed without having to install jumpers or deal with point-to-point wiring. In fact, the Digital Surround Decoder is in many respects more "plug and play" than many computers that lay claim to the name. The modularity of the Digital Surround Decoder ensures that the product can easily accommodate changes in the future that might require new hardware. For example, if the industry were to establish a new standard for digital interconnection, using a different physical connector, most products would be obsolete overnight; with the PDSD, you would merely slide a new module into a slot. Mind you, we do not believe that you will have to change hardware anytime soon. We even went to the trouble of designing our own high bandwidth, programmable DIR (Digital Interface Receiver), the circuitry that actually receives a digital signal and determine "which bits go where." We did this to ensure that the product you buy today can handle everything that a dedicated DVD-for-audio disc may offer in the future. You see, conventional DIRs cannot handle the full 10 Mb/sec data rate of DVD... but ours can. Moreover, our DIR actually reclocks the incoming digital signal to greatly reduce timing errors in the signal (jitter), making every source you connect to the Digital Surround Decoder sound better than it could otherwise. software updatable All the software that the Digital Surround Decoder uses is stored in special "flash" memory that can easily be updated as improvements are made available. These improvements can affect both operational and performance enhancements. For example, if a new, dedicated DVD-for-audio format is decided at some point, it may well have 24-bit, 96 kHz sampling rate data on it as well as traditional 16 bit, 44.1 kHz data (for backwards compatibility). With a simple software download a short time after such a standard is announced, your Digital Surround Decoder would be able to both decode and play back the new audio standard, and flip back and forth between the two versions of the music on the disc for comparison purposes. The Digital Surround Decoder is designed to avoid the premature obsolescence that will be the hallmark of far too many products sold in these changing times. multichannel The Digital Surround Decoder is designed to be flexible with respect to its audio configurations, as well. In its standard configuration, it provides the standard 5.1 channel selection of outputs made popular by home theater. However, it can 14 also be upgraded to an eight channel processor simply by inserting another card, whether to accommodate larger rooms or more sophisticated audio processing. It is just a matter of what you want the system to do. That way, you can have the system the way you want it to work, rather than the way we thought you'd want it to work. (After all, a no-compromise, high performance audio system should not be "one size fits all.") Moreover, the PDSD was designed from the outset to be a high end multichannel product. All channels use full 20-bit multibit D/A converters rather then the less costly single-bit converters commonly found in multichannel products, for the simple reason that they sound better. audio computer Conventional audio DSP design requires the addition of costly hardware every time you wish to add functionality. In these designs, Dolby Digital (AC-3) has its own, dedicated DSP chip and associated supporting circuitry; so does DTS; so does MPEG/Musicam. Want a new feature? Buy more hardware. This strikes us as ridiculous. Y would not buy a computer for writing, knowing that you would have to buy ou another computer for calculations, and another for graphics, and a fourth for database work. To do so would be enormously wasteful, as expensive microprocessors would sit idly while you were doing something else. The same is true in "audio computers." The Digital Surround Decoder is the first of a new generation of power DSP (Digital Signal Processing) engines that can load software in and out of memory dynamically, as your computer does. Want to listen to a Dolby Digital soundtrack? The PDSD loads the appropriate software and runs it. Movie over, want to listen to CD? No problem. Oh, the CD is DTS-encoded? Still no problem -- the DTS software is loaded and runs on the same chip that had been running Dolby Digital a few moments ago. Madrigal was an early partner of Motorola in developing the next generation of DSP chips, the 56300-series. Designed to replace the aging 5600X series, these new chips offer twice the performance and vastly more flexibility. With three such chips in each Digital Surround Decoder, we have the power to run any of these programs as well as our own proprietary digital filtering algorithms. Why did we develop such advanced technology? Simple: better performance for today, and for tomorrow. 15 1 digital surround decoder 2 TM LU CA S FI LM ® power digital processing PR O C E E D Front Panel 1 DIGITAL PROCESSING LED This digital processing LED is normally completely off when an analog source has been chosen, indicating that no digital signal processing is even being attempted. If the PDSD cannot communicate with the PAV (due to a forgotten communications cable, for example), the digital processing LED will blink to indicate that it is trying (but not succeeding) to communicate with the PAV . The digital processing LED glows red when a digital signal has been selected, but cannot be "locked" onto and used. (Example: the RF output of a laserdisc player typically goes "dead" during scanning, chapter searches, and side changes, interrupting the signal and preventing the Digital Surround Decoder from doing what you have "asked" it to do.) Finally, the digital processing LED glows amber when a digital signal has both been chosen and is being successfully received, indicating that digital processing is possible. The Digital Surround Decoder will automatically and transparently decode PCM (including a digital version of Dolby Pro Logic), Dolby Digital (formerly called AC-3) and DTS Coherent Sound, switching to whatever form of digital decoding and processing the signal requires. In any of these cases, the digital processing LED will glow amber to indicate that the Digital Surround Decoder is handling the signal for you. If you wish to learn which of these digital processes is active, press the status button on the remote control. 16 2 POWER & POWER LED Assuming that the Digital Surround Decoder's power cord is connected to AC power, pressing this latching power button connects the PDSD to the AC mains and turns on the unit. When power is restored after an interruption, the PDSD will be ready to operate (that is, it won't be in standby), after a few moments' delay to allow its circuits to stabilize. While the Digital Surround Decoder is in standby, the LED above the power button is red. When the Digital Surround Decoder is ready to operate (that is, when it is not in standby mode), this LED is amber. Naturally, when AC power is off, the LED is off. 17 1 2 3 4 5 6 7 8 9 10 11 12 7 2 3 1 R L main R L R L C S 8 120VAC ~ 60Hz digital out L 12 3 12 3 12 3 remote output digital inputs front output 9 digital inputs rear surround 4 5 12 3 R L center/sub output pav pass-through surround output 6 R R R C 21 3 12 3 12 3 12 3 12 3 (optional) (optional) 1 2 digital out L L 2 processor loop 21 3 12 3 front output aux. output inputs R R 21 3 Rear Panel Caution! Disconnect all associated equipment from the AC mains BEFORE making any signal connections and applying power to the Digital Surround Decoder. 1 AC MAINS INPUT This input accepts AC power from the AC mains (via the supplied AC cable). Warning! The Digital Surround Decoder is set internally for 100, 120, 220, 230, or 240VAC mains operation at either 50 or 60Hz. Make sure that the label on the rear of the unit indicates the correct AC operating voltage and frequency for your location before connecting it to AC mains. Connect the female end of this cable to the Digital Surround Decoder. Connect the male end of this cable to wall outlet. 18 12 3 12 3 12 3 1 master 10 11 C S center/sub control slave rem on/off L L S 1 2 comm. ac power cord polarity To Digital Surround Decoder To AC mains 1 3 2 1 3 2 1 = Line (hot) 2 = Neutral 3 = Earth ground The power consumption of the Digital Surround Decoder is only about 100 watts, about the same as a light bulb. As such most people will leave it on (or in standby) at all times. If you elect to turn the PDSD completely off (rather than in placing it in standby), we advise waiting at least five seconds between power cycles to allow the normal power-up sequence to complete without interruption. 2 DIGITAL INPUTS 7- 1 1 Please remember to make a note of what sources you connect to which inputs.
