The unit has 2 separate outputs, A & B, each with its own master volume and tone controls. Each output provides an independent mix of a built-in program input and up to six module inputs. Each input has two level controls, to set the input level of each mix. A variable muting feature (60dB range) mutes the program input when rear panel contacts are shorted. The Bogen plug-in modules define the the function of each module input. Active-bus mixing allows interaction for three-level priority. Modules set to priority level 1 can receive (are muted by) priority signals from modules set to levels 2 and 3. Modules set to priority level 2 send priority signals to (and mute) modules set to priority level 1, and receive priority signals from modules set to priority level 3. (Modules set to priority level 1 or 2 are also muted when the rear panel MUTE terminals are shorted through a contact closure.) Modules set to priority level 3 send priority signals to (and mute) the program input and modules set to level 1 or 2. i j The DMP-06 is designed for maintenance-free operation. High-performance output circuitry assures peak performance even under the most demanding applications. The frequency response is flat within +0, -ldB from 20Hz to 20kHz. Distortion is less than 0 2% at maximum output across the entire bandwidth of 20Hz to 20kHz (+0,-ldB), and is typically less than 0.01%. Maximum noise level is 72dB with the MASTER control at maximum. Input sensitivity is lOOmV/lOkilohms for the module and program inputs. Each output channel provides direct 600-ohm unbalanced, and transformer-coupled, 600-ohm balanced taps. Connection is via screw terminals. Either mixing bus also may be strapped to other D-Series equipment through separate bridging jacks. Full range bass and treble controls provide ± lOdB cut or boost at 10Hz and 10kHz, respectively. Tone control defeat switches are located in the module port cage to prevent tampering after installation. The overall level for each output is set with separate MASTER controls, and is displayed by three-color bar-type LED output meters, which illuminate red to indicate possible signal clipping conditions. The unit operates from 120V, 50-60Hz AC. A rocker-type power switch illuminates when the power is on. Dimensions are 5-l/2"H x 16-1/2"W x ll-3/8"D. The unit may be mounted in standard equipment racks using Model DRK-3 Rack Panel Kit. INSTALLATION UNPACKING The mixer was carefully checked before leaving the factory. Inspect the shipping container and the unit closely for evidence of improper handling. If the unit has been damaged, place an immediate claim with the dealer/distributor from whom the unit was purchased. If the unit was shipped directly to you, file a claim with the transportation carrier in accordance with ICC regulations. RACK MOUNTING The mixer is designed for installation in standard equipment racks, using Model DRK-3 Rack Panel Kit. MODULES Caution Be sure that the front-panel-mounted POWER switch is in the OFF position before installing or removing modules. Modules are easily inserted in any available port of the module cage. Align the top and bottom edges of the module circuit board in the slots of the port, and slide the module into the cage to engage the card edge connectors. Secure the module to the amplifier with two screws. PRIORITY Set the priority level on modules so equipped to the desired level before installing them in the amplifier. The level is set by repositioning printed circuit board-mounted shunts. The screening on the module printed circuit board shows which pins to connect for the desired priority level. PRIORITY LEVEL 1 The module rcccivcs, and is muted by, priority signals from any module set to priority level 2 or 3. A module set to priority level 1 is also muted when the rear panel MUTE terminals are shorted through a contact closure. (The program input is pre-set at level 1.) PRIORITY LEVEL 2 — The module sends priority signals to mute any module set to priority level 1, and receives priority signals from any module set to priority level 3. A module set to priority level 2 is also muted when the rear panel MUTE terminals are shorted through a contact closure. PRIORITY LEVEL 3 — The module set to priority level 3 sends priority signals to mute modules set to priority level 1 or 2 and the program (PGM) input. (The rear panel MUTE terminals function at level 3 when shorted through a contact closure.) OUTPUT TERMINAL STRIPS Each output channel provides direct 600-ohm unbalanced, and transformer-coupled, 600-ohm balanced taps. Connection is via rear panel screw terminal strips. Use single-conductor shielded cable when using the direct output. Connect the cable shield to the GND terminal. Use two conductor shielded cable when using the transformer-couplcd output. Connect the conductors to the HI and LO terminals; connect the cable shield to the CT terminal. When the transformer-coupled output is used to feed the sound system...
