Signal Input and Output Level Controls The Orion 7005 amplifier has separate front, rear, and sub level gain adjustments. The input sensitivity of these adjustments range from 200mV up to 5V. This allows easy integration from any source unit. Refer to the Testing the System and the Adjusting the Sound of the System sections for detailed instructions on setting up the level controls. Four-Channel Amplifier Input Configuration The 4CH / 2CH switch routes input from the front inputs to the rear section of the amplifier. This allows the Orion 7005 channel amplifier to utilize a single set of RCA's to feed signal to the front and rear channels of the amplifier. When the switch is to the right (2CH position), signal from the front inputs is routed to the rear channels.When the switch is to the left (4CH position), front and rear inputs are independent. This allows a source unit with an internal fader to fade between the front and rear outputs. IN / EXT Switch The IN / EXT switch routes input to the subwoofer section of the amplifier. This allows the Orion 7005 channel amplifier to utilize a single set of RCA's to feed signal to the subwoofer channel of the amplifier. When the switch is to the right (EXT position), the subwoofer channel is independent from the other inputs. Signal from the subwoofer RCA inputs is routed to the subwoofer input. This allows a source unit with a subwoofer out to control the subwoofer independently of the other channels. When the switch is to the left (IN position), the inputs from the front and rear channels are summed together and routed to the subwoofer channel. Internal Crossover Configuration The crossover section of the Orion 7005 amplifier is continuously variable and extremely flexible. The front, rear, and subwoofer channels are independently controlled. There are different crossover configurations possible allowing high-pass, low-pass and band-pass configurations. This circuit is designed to optimize the performance of all of the components used in a high quality system. 6 ©2003 Directed Electronics, Inc. When using Orion loudspeakers, minor deviations from the recommended frequency ranges can provide superior results depending on your speaker locations and your vehicle acoustics. Setting crossover frequencies higher than recommended will not cause damage and may provide superior sonic results depending on your system's performance goals. Refer to your loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for your system. WARNING! DO NOT set crossover frequencies lower than the speakers recommended operating range. This can cause driver failure that is not covered by manufacturer's warranty. Subwoofer High-Pass This circuit is designed to optimize the performance of Orion subwoofers in all types of enclosures. WARNING! DO NOT set crossover frequencies lower than the speakers recommended operating range. This can cause driver failure that is not covered by manufacturer's warranty. Low-Pass Crossover When the switch is to the right (OFF position), the low-pass crossover is bypassed. When the switch is centered (12 position), the low-pass crossover is active with a 2nd order (12dB per octave) slope. When the switch is to the right (24 position), the low-pass crossover is active with a 4th order (24dB per octave) slope. The low-pass crossover is continuously variable from 20Hz to 3kHz. High-Pass Crossover When the switch is to the left (OFF position), the high-pass crossover is bypassed. When the switch is to the right (ON position), the high-pass crossover is active with a 2nd Order (12dB per Octave) slope. The high-pass crossover is continuously variable from 10Hz to 3kHz. The high-pass crossover is optimized for use as a subsonic filter. Additionally, boost can be added at the high-pass crossover frequency for improved bass output while still protecting the woofer from excessive excursion. The INTELLi Q adjustment allows up to 10 dB of boost at the selected crossover frequency. WARNING! Exercise caution when setting INTELLi Q. Maximum boost can potentially cause woofer damage due to overexcursion. Fine Tunning the Crossover The low-pass and high-pass crossover sections are each marked at four frequency points for ease of system adjustment. The low-pass crossover section is marked at 30Hz, 50Hz, 150Hz, and 250Hz. The high-pass crossover section is marked at 20Hz, 33Hz, 90Hz and 150Hz. Specific crossover points can be chosen based on the recommended operational bandwidth of your speakers. Adjusting INTELLi Q Incorporated in the high-pass crossover, INTELLi Q maximizes the performance of a subwoofer. The high-pass subsonic filter removes unwanted bass output from the woofer, increasing the output of a subwoofer by as much as 3 dB due to the increased mechanical power handling. Depending on the enclosure, using INTELLi Q can increase the low frequency response by an additional 10dB! The type of enclosure used and the woofer's excursion capability determine acceptable boost levels. Listed below are recommended boost levels for different enclosure designs. ©2003 Directed Electronics, Inc. 7 Enclosure Type 0dB Infinite Baffle Tune above Fs of woofer +3dB Boost Levels +6dB +10dB High X-Max Drivers--Tune above Fs of woofer Tune above Fs of woofer Not Not Recommended Recommended Sealed Tune above Fs of woofer High X-Max Drivers--Tune above Fs of woofer Tune to port frequency High X-Max Drivers--Tune above Fs of woofer Tune to port frequency Set crossover to Fs of woofer Not Recommended Vented Tune to port frequency Tune above Fs of woofer Tune to port frequency Tune above Fs of woofer High X-Max Drivers--Tune to port frequency Not Recommended Sealed Band-pass Vented Band-pass Tune to port frequency Set crossover to Fs of woofer Tune to port frequency Set crossover to Fs of woofer High X-Max Drivers--Tune to port frequency Not Recommended Aperiodic Infinite Baffle Example High-Pass Set at 30Hz By removing low frequency signal that the woofer cannot produce, the woofer can play its capable range louder. The first example is an infinite baffle situation. The left graph displays the frequency response of a 12-inch woofer in an infinite baffle application without the high-pass filter, with the filter and with the filter and the INTELLi Q set to +3dB. As you can see, with +3dB of boost and the high pass filter set to 30Hz, the woofer has more output down to 25Hz and less overall excursion when compared to the non-high-pass response. Maximum physical excursion capability of the woofer is 15mm. NOTE: The left graph is the response; the right graph is the driver excursion. These designations apply to the following graphs as well. 8 ©2003 Directed Electronics, Inc. Sealed Example High-Pass Set at 20Hz This sealed example is the same 12-inch woofer in the recommended sealed enclosure. Up to 6 dB of boost is capable if 20 Hz was used. With +6dB of boost, the woofer has more output down to 15 Hz. Sealed Example High-Pass Set at 30Hz In this example, the frequency has been increased to 30 Hz. Up to 6 dB of boost is capable at this frequency. With +6dB of boost, the woofer has more output down to 23 Hz. The overall usable output is increased. Vented Example High-Pass Set at 30Hz Vented enclosures benefit most from the INTELLi Q. Up to 10 dB of boost is capable at the box tuning frequency of 30 Hz. With +10dB of boost, the woofer has more output down to 22 Hz. The excursion below the tuning frequency has been greatly reduced. ©2003 Directed Electronics, Inc. 9 Remote Gain Operation The remote gain port provides easy remote access to the internal gain structure of the subwoofer section of the Orion 7005 amplifier. The RGC-1 plugs into the amplifier via the 1/8" mini jack plug. It can be installed in the front of the vehicle to control the amplifier gain level, and can be used as a bass level control on the subwoofer channel of the Orion 7005. AMPLIFIER WIRING Power Connections Fuse Size: 70 AMP MAXI Minimum eight-gauge power and ground cable is recommended for acceptable performance. Fuse power wire prior to wire passing through panels or near sharp edges and less than 18" from battery. Ground amplifier to a good chassis ground as close as possible to the amplifier. Add extra ground wire (minimum eight-gauge) between the negative terminal of the battery and the chassis. The addition of a ground wire from the battery to the chassis of the vehicle improves the ability of the battery to supply power to the amplifier. This helps especially in newer vehicles, where the current delivery of the factory electrical system was designed only to accommodate electronics supplied by the auto manufacturer. NOTE: Speaker Connections Five Channel Stereo Configuration Front, rear, and subwoofer channels' lowest recommended impedance is 2W stereo. Crossover mode, output, and gain configurations are independently adjustable between the front, rear, and subwoofer channels. Two-channel or four-channel input can be used for this configuration. For source unit fading, use the four-channel input mode. The subwoofer channel can use internal or external input. If the source unit has a separate subwoofer out, use the external input configuration. Front, rear, and subwoofer outputs can be configured for high-pass, low-pass, band-pass, or full range operation. 10 ©2003 Directed Electronics, Inc. Three Channel Bridged Stereo Configuration Front and rear channels are configured for bridged two-channel operation Lowest recommended impedance for both front and rear channels is 4W Crossover and gain configurations are independently adjustable between the front, rear, and subwoofer channels. Two-channel operation is recommended for this operational mode. Front and rear outputs can be configured for high-pass, low-pass, band-pass, or full range operation. Front and rear outputs can be configured for stereo (right channels will have right output, left channels will have left output) or summed two-channel operation (front speaker bridged, rear speaker bridged). Lowest recommended impedance for the subwoofer channel is 2W. The subwoofer channel can use internal or external input. If the source unit has a separate subwoofer out, use the external input configuration. ©2003 Directed Electronics, Inc. 11 AMPLIFIER INSTALLATION Choosing Mounting Locations The location of your amplifier will depend on several important issues. Due to the low profile size of the Orion amplifiers, there are many possible installation locations that will yield satisfactory amplifier performance. Always mount the amplifier in a place that protects the amplifier from the elements. In addition, mount the amplifier on a stable, flat surface. NOTE: Mounting amplifiers upside down is not recommended and may cause premature thermal shutdown. Do not mount any amplifier in the engine compartment. Amplifiers are not designed to endure the harsh environment of the exterior elements. WARNING! Passenger Compartment If you are going to mount the amplifier in the passenger compartment, make sure you have adequate room for ventilation. The amplifiers have been designed to make under-seat mounting possible. When mounting your amplifier under a seat or similar area, keep a minimum of 1" of clearance around the amplifier for adequate cooling. Trunk Compartment Mounting your amplifier in the trunk provides excellent performance as long as you do not restrict the airflow around the heatsink of the amplifier. For optimal results, mount the amplifier with as much clearance as possible. This type of mounting will yield the best cooling due to the convection effect of the amplifier chassis. General Precautions and Installation Tips WARNING! Be careful not to cut or drill into gas tanks, fuel lines, brake lines, hydraulic lines, vacuum lines, or electrical wiring when working on your vehicle. Disconnect the vehicle's ground wire at the battery before making or breaking connections to the audio system's power supply terminals. Do not use this amplifier unmounted. Failing to securely mount the amplifier can result in damage or injury, particularly in the event of an accident. An unmounted amplifier becomes a dangerous projectile in the event of a crash. Never mount the amplifier where it might get wet. Mount the amplifier so the wire connections will not be pulled. Route the wires where they will not be scraped, pinched or damaged in any fashion. The +12V power supply wire must be fused as close as possible to the battery terminal, ideally within 18". Use the recommended fuse size or circuit breaker listed in the Power Connections section of this manual. If you need to replace the fuse plugged into the side of the amplifier, replace the fuse with the same size ATC / MAXI type fuse that came with the amplifier. If you are not sure as to the correct value, refer to the Power Connections section of this manual for details. Using a higher current fuse may result in damage to the amplifier that is not covered under warranty. NOTE: Make sure all the equipment in the system is turned off when making or breaking connections to the input RCA's or speaker terminals. Turn on the system and slowly turn up the volume control only after double checking all wire connections. 12 ©2003 Directed Electronics, Inc. Power for systems with a single amplifier can be supplied by most automotive electrical systems. Systems with multiple amplifiers may require a higher capacity battery, alternator or the use of a storage capacitor. We strongly recommend the use of a Directed Audio Essentials power capacitor with an extra battery in larger stereo systems. Orion amplifiers generate a certain amount of heat as part of normal operation. Be sure the area around the amplifier is unobstructed to allow adequate air circulation. Remember, beach blankets, last week's laundry, school books and homework papers located on top of the amplifier do not improve air flow and may become damaged. Tools of the Trade Listed below are the majority of the tools required to perform an installation. Having the proper tools will make the installation that much easier. Some of these tools are necessities; some will just make the job easier. Allen Wrenches (2.5mm and 3mm) DMM or VOM Electric drill with assorted drill bits Grommets Heat shrink tubing Marking pen Nylon tie straps Phillips and flat blade screw drivers Pliers (standard and needle nose) Reference CD with 1 kHz Sine Wave at 0dB level (all bits high) RTA (real time analyzer) Soldering iron and solder Utility knife Wire brush or sandpaper for chassis grounding Wire crimper Wire cutters Wire strippers Step By Step Installation Step 1 Step 2 Step 3 Determine the location for the amplifier. Refer to the Choosing Mounting Locations section of this guide for detailed information. Decide on the system configuration for your amplifier. For system suggestions, refer to the Speaker Connections section of this guide. Run all the wires from the amplifier location to the speakers, source unit, and battery. Do not connect the battery at this time. Be sure to run RCAs and power and speaker wires away from factory electrical wires and system as they pose a great potential for induced system noise. Pre-drill amplifier mounting holes. Be sure to "think before you drill". Gas tanks, fuel lines, and other obstructions have a nasty way of hiding themselves. For best results use a marking pen to mark the mounting holes and pre-drill these holes with a standard 1/8" drill bit. Mount the amplifier. Make sure the amplifier is mounted on a flat surface. If this is not possible, do not over tighten the screws so that the chassis of the amplifier is twisted or bent. Step 4 Step 5 ©2003 Directed Electronics, Inc. 13 Step 6 Step 7 Step 8 Step 9 Turn the vehicle's key switch to the off position. Disconnect the vehicle's battery ground terminal. Connect power wires to the amplifier (ground first, then 12 V(+) and RGC). Connect the RCA and speaker wires to the amplifier. Check the quality of your speakers and signal connections. This will determine the ultimate performance of your Orion amplifier. Refer to the Signal Input and Output Level Controls and Speaker Connections sections of this guide for correct wiring instructions. Reconnect the ground terminal to the battery after power, speaker, and connections are completed. Set crossovers. Refer to the Internal Crossover Configuration section of this manual for detailed instructions. Once satisfied that all connections and settings are correct, install the fuse located near the vehicle's battery and proceed to the Testing the System section of this manual. Never exceed the recommended fuse size of this amplifier. Failure to do so will result in the voiding of your warranty and possible damage to the amplifier. Step 10 Step 11 Step 12 WARNING! SET UP AND TROUBLESHOOTING Testing the System After you have completed the installation, you need to test the system. This will help ensure years of trouble-free operation. Please refer to the listed steps below when testing the sound of your Orion system. Step 1 Step 2 Step 3 Step 4 Check all the wiring connections to be sure they are correct and secure. Turn the signal source volume control all the way down. Set any tone controls to their flat or defeated positions. This includes the loudness control. Turn the level controls of the amplifier to their minimum positions. Turn the source unit on. Check to see if the power LED located on the connection side of the amplifier is on. If not, please refer to the Power Connections and the Troubleshooting Tips sections of this manual for instructions. If using an aftermarket source unit, turn the level controls of the amplifier about one quarter of a turn. Slowly increase the volume level of the source unit to so that you can hear the output of the system. If no sound is heard or if the output is distorted, turn the system off immediately. Refer to the Power Connections and the Troubleshooting Tips sections of this manual to solve your installation problems. Check to make sure the output for each channel is correct. If the active crossovers are used, check to make sure that each output is correct from the amplifier. When using active crossovers on midrange and tweeters, do not use crossover frequencies lower than recommended. If the system is not configured properly, refer to the Internal Crossover Configuration section of this manual and take corrective action. If the output is clear and undistorted, continue to the Adjusting the Sound of the System section of this manual. Step 5 Step 6 Step 7 14 ©2003 Directed Electronics, Inc. Adjusting the Sound of the System Once you have checked the system's operation, adjust the sound of the system. Adjusting the sound of the system is accomplished by setting the level controls and adjusting the internal crossovers. Step 1 Step 2 Step 3 Step 4 Turn the signal source volume control all the way down. Set any tone controls to their flat or defeated positions. This includes the loudness control. Turn the level controls of the amplifier to their minimum positions. Choose music with high dynamic content that you like, with which you are familiar, and will be used most often in the system. Turn the source unit's volume control up to its highest undistorted output level. If you lack test equipment, this point occurs between 3/4 to full volume depending on the quality of your source unit. Listen for any audible distortion. If any distortion is audible, reduce the volume of the source unit until you have an undistorted output. Leave the volume control at this position during your system tuning. While listening to your chosen dynamic music, turn up the level control corresponding to the midrange output until you hear slight distortion and turn the level control back slightly for an undistorted output. Depending on your system, the midrange and tweeter output may be on the same output channels. Turn up the level control corresponding to the tweeter output until you hear slight distortion and turn back the level control slightly for an undistorted output. Depending on your system the midrange and tweeter output may be on the same output channels. Fine-tune the output level between midrange and tweeters. Refer to the Internal Crossover Configuration section of this manual for detailed instructions. Repeat Steps 5-7 for the rear speakers. If you do not have rear speakers continue to Step 10. Set levels between the front and rear midrange and tweeters for optimum front/rear balance. Turn up the level control corresponding to the woofer output until you hear slight distortion and turn back the level control slightly for an undistorted output. Fine-tune the output level between satellite speakers and the woofers. Refer to the Internal Crossover Configuration section of this manual for detailed instructions. If using an RGC-1, adjust the level to the output of the woofer to match the sonic requirements of the system. Enjoy your awesome Orion sound system.
