Never before have the technologies of high-resolution audio, hard disk recording, digital signal processing, and CD recording been combined into a single, stand-alone, integrated audio device that is so remarkably easy to use. 1.1 MASTERLINK HIGHLIGHTS · · · · · · · · · 24-bit A/D and D/A converters Sampling rates of up to 96kHz Large internal hard disk, allowing many hours of CD-quality audio recording 8X read / 4X write speed CD-R 48-bit floating point DSP +4 dBu balanced XLR and ­10dBV RCA analog audio connectors IEC958 Type 1 balanced XLR (AES/EBU) and Coaxial digital audio connections Custom vacuum fluorescent display Stereo headphone output with volume control 1.2 UNPACKING AND INSPECTION Please retain the MasterLink's shipping carton, which is designed to protect the unit during shipping, in the unlikely event that you need to return the MasterLink for servicing. Some carriers have restrictions on shipping electronic equipment without the original packing. The shipping carton contains: · · · · · MasterLink with the same serial number shown on shipping carton Power cable Detachable rack ears MasterLink infrared remote control unit This instruction manual WARRANTY INFORMATION: In order to commence your warranty and to be advised of future updates, please register your purchase immediately at www.alesis.com through the online warranty registration. ALESIS ML-9600 REFERENCE MANUAL 1 Chapter 1 1.3 AC POWER HOOKUP 1 2 Make sure the MasterLink is turned off. It's good practice not to turn on the MasterLink until all other cables are hooked up. Before plugging in to AC power, note that the MasterLink's IEC-spec AC cord (do not substitute any other AC cord) must feed a 3-pin outlet, where the third, round pin connects to ground. The ground connection is an important safety feature designed to keep the chassis of electronic devices at ground potential. Unfortunately, the presence of a third ground pin does not always indicate a properly grounded outlet; check this with an AC line tester. If the outlet is not grounded, consult with a licensed electrician. Plug the power cord's female end into the MasterLink's power input socket, and the male (plug) end into any AC power source from 90 to 250 volts, 50 or 60 Hz. 3 Your MasterLink includes the correct power cord for your country or local area. When using a MasterLink abroad , use only the following alternative power cords approved for use with ML-9600: · · · · For 90-120 VAC 50/60 Hz operation in the US, Canada and/or Japan, use Alesis UL/CSA power cord #7-41-0001. For 240 VAC 50 Hz operation in England, use Alesis UK power cord #7-41-0004. For 220 VAC 50 Hz operation in Europe and Scandinavia, use Alesis EU power cord #7-410002. For 240 VAC 50 Hz operation in Australia, use Alesis AS power cord #7-41-0003. Alesis is not responsible for problems caused by using the MasterLink or any associated equipment with improper AC wiring. 1.4 LINE CONDITIONERS AND PROTECTORS Although the MasterLink tolerates typical voltage variations, the AC line voltage may contain spikes or transients that can possibly stress your equipment and, over time, cause a failure. There are three main ways to protect against this, listed in ascending order of cost and complexity: · · · Line spike/surge protectors. Relatively inexpensive, these help protect against strong surges and spikes (they usually need to be replaced after enduring an extremely strong spike). Line filters. These generally combine spike/surge protection with filters that remove some line noise (dimmer hash, transients from other appliances, etc.). Uninterruptible power supply (UPS). This is the best option. A UPS provides power even if the AC power line fails completely. Intended for computer applications, a UPS allows an orderly shutdown in the event of a power outage. Furthermore, the isolation it provides from the power line minimizes all forms of interference - spikes, noise, etc. 2 ALESIS ML-9600 REFERENCE MANUAL Chapter 1 1.5 ABOUT AUDIO CABLES The connections between the MasterLink and your studio are your music's lifeline. Use only high quality, low-capacitance, shielded cables with a stranded (not solid) internal conductor and lowresistance shield. Although quality cables cost more, they make a difference. When routing cables: · · · Do not bundle audio cables with AC power cords. Avoid running audio cables near sources of electromagnetic interference such as transformers, monitors, computers, etc. Do not place cables where they can be stepped on. Stepping on a cable may not cause immediate damage, but it can compress the insulation between the center conductor and shield (degrading performance) or reduce the cable's reliability. Avoid twisting the cable or making sharp, right angle turns. Never unplug a cable by pulling on the wire itself. Always unplug by firmly grasping the plug's body, and pulling directly outward. Although Alesis does not endorse any specific product, chemicals such as Tweek and Cramolin, when applied to electrical connectors, are claimed to improve the electrical contact between connectors. · · · ALESIS ML-9600 REFERENCE MANUAL 3 Chapter 2 ONCE AROUND THE ML9600 2.1 THE FRONT PANEL Front Panel Feature 1.

Because the ML-9600 has both an internal hard disk and an internal CD-R drive, the ML-9600 has two fundamental modes of operation: HD mode and CD mode. The HD/CD button in the upper right-hand corner of the unit toggles between those modes, and changes the functions of the transport control buttons (PLAY, REC, STOP, , SCAN, and SCAN ). SKIP, SKIP HD mode is used when recording to or playing back from the internal Hard Disk, and when creating compact discs from audio recorded on the hard disk. CD mode is used when playing back pre-recorded Compact Discs, or when you want to copy tracks from a CD to the internal hard disk. 3.2 HD RECORDING SETTINGS Before recording any audio to the hard disk, it is important to choose the desired input source, sample rate, and word length for the recording. The ML-9600 offers great flexibility with respect to these last two parameters, allowing a total of 12 different resolutions to be recorded. 3.2A INPUT SOURCE Two input sources are possible: Analog or Digital. Pressing the INPUT SOURCE button on the front panel will toggle between the two. Analog audio can either be input via the XLR or RCA jacks. The XLR jacks are +4dBu nominal input level, while the RCA jacks are ­10dBV nominal input level. Both sets of inputs have 15dB of headroom from nominal input to clipping, resulting in a maximum of +19dBu at the XLR inputs, and +5dBV at the RCA inputs. Digital audio data is expected in IEC958 Type 1 format (professional) input either via the balanced XLR inputs or via the unbalanced RCA inputs. Important: The ML-9600 does not switch between its balanced and unbalanced digital audio inputs. Both inputs are active simultaneously, and if digital audio data is sent to both inputs simultaneously data corruption will occur. When the input source is set to Digital, the system word clock rate is automatically set to the rate of the incoming digital audio signal. This is true whether in playback or record, and in all modes of operation. This allows the ML-9600 to operate as a clock slave in an all-digital setup. Caution must be used, however, as all audio playback while in digital input mode will be at the incoming clock rate, despite the rate at which the audio was recorded. For instance, if audio is recorded at 96kHz to the hard drive, and then the unit is placed in digital input mode with the incoming sample rate at 48kHz, that recorded audio will play at ½ play speed. NOTE: If the ML-9600 is in digital input mode and the incoming digital data is interrupted (by removing the cable, for instance), the input source will switch automatically to Analog, with the sample rate set to the last valid sample rate detected on the digital input, and with the word length remaining the same as what it was set to in digital input mode. ALESIS ML-9600 REFERENCE MANUAL 7 Chapter 3 3.2B SAMPLE RATE Four sample rates are available: 44.1kHz, 48kHz, 88.2kHz, and 96kHz. Pressing the SAMPLE RATE button on the front panel will toggle between these four rates. Sample rates are not user adjustable when in digital input mode; the sample rate will automatically be set to the rate of the incoming digital data. 3.2C WORD LENGTH Three word lengths are available: 16-bit, 20-bit, and 24-bit. Pressing the WORD LENGTH button on the front panel will toggle between these three word lengths. Word lengths are user-selectable when in digital input mode; note that it is therefore possible to select a shorter word length than is being received at the digital input, resulting in truncated data. 8 ALESIS ML-9600 REFERENCE MANUAL Chapter 4 WORKING WITH PLAYLISTS When you are in "HD" mode, you will be working with Playlists. Playlists are the basic structures in which Tracks are organized before creating CDs, and are therefore one of the most crucial parts of the operation of the ML-9600 to understand. Playlists are simple in concept ­ they are lists of the songs that you want to have on your CD. Within a playlist, you choose the order in which you want your songs to appear on the final CD, the amount of time between songs, the relative volume of the songs, and the type of signal processing applied to each song. You can think of a selected playlist as a "virtual CD"; that is, in playlist select mode the playlist should act as a compact disc would, except that its data is coming off of the internal hard disk. 4.1 SELECTING A PLAYLIST The ML-9600 has sixteen independent playlists, each containing up to 99 Tracks. There is an additional "special" playlist located after Playlist 16 that is reserved for rendered CD images; see Chapter 6: Creating A CD for more information about this special playlist. To select a playlist, press the PLAYLIST SELECT button on the front panel underneath the main display. The words "Playlist XX" will be displayed on the first line of the display, where "XX" will be a number between 01 and 16. The cursor will be under the "XX", and pressing the UP/YES button will increment through the playlists, while pressing DOWN/NO will decrement through the playlists. Figure 4.1.1 shows a sample playlist select display. Figure 4.1.1 Sample Playlist Select Display This particular playlist is named "PList 01" (the default playlist name for Playlist 1), and has only one Track in it, indicated by the "01 Tks" in the lower right hand side of the display. 4.2 NAMING A PLAYLIST Once a playlist has been selected, you may wish to change its name. Pressing CURSOR RIGHT will move the cursor to the first character of the name of the playlist. Once the cursor is in the name field, pressing UP/YES or DOWN/NO will scroll though a set of alphanumeric characters for each of the eight characters of the playlist's name. Exit the name field by pressing CURSOR LEFT until the cursor is once again under the playlist number. ALESIS ML-9600 REFERENCE MANUAL 9 Chapter 4 4.3 AUDITIONING A PLAYLIST After a playlist has been selected, you may listen to part or all of that playlist by using the transport buttons on the right side of the front panel (PLAY/PAUSE, SKIP, SKIP , SCAN, and ). Pressing PLAY/PAUSE after a playlist is selected will play from the beginning of the SCAN playlist, light the Track Number indicator, and begin displaying Track Time in the Track Time Display (the format of which is determined by the TIME DISPLAY button). Pressing SKIP or SKIP will skip through the Tracks, while pressing SCAN or SCAN will rewind or fast-forward through the Tracks while allowing you to hear the audio.

"Playlist Edit Mode" is where most of the work will be done when preparing a playlist for eventual CD creation. While in playlist edit mode, you may: · Record new Tracks · Play back previously recorded Tracks · Delete Tracks · Change Track order in playlist · Change Track to Track spacing · Adjust the volume of a Track · Add DSP to a Track · Apply fades to a Track · Write protect a Track to prevent accidental erasure · Split a Track · Join two Tracks 4.4A EMPTY PLAYLISTS If the PLAYLIST EDIT button is pressed and there are no Tracks recorded in the playlist, the screen will indicate that you have an "empty" playlist, as shown in Figure 4.4.1.
