User manual BIAMP 801 SERIES

[. . . ] Each mic/line channel uses a differentially balanced, discrete transistor preamplifier for low noise and low distortion performance. Special features, including a limiter and remote level control, make the 801 SERIES SERIES extremely versatile. The 801 SERIES SERIES mixer is dependable, easy to install, simple to operate, and carries a five-year warranty. 1 FRONT PANEL trim trim trim trim trim trim trim trim threshold 801 SERIES SERIES +10 1 +10 2 +10 3 +10 4 +10 5 +10 6 +10 7 +10 8 +10 aux bass treble -20 master limit on +10 Indicator (Channels 1~8 & Aux): These red LEDs will light whenever channel signal levels reach +10dB (8dB below clipping). Use this feature to aid in adjusting the Trim controls (see below). [. . . ] If a pre-Master Level output is desired, connect to Main Patch with Tip & Ring (send) and Sleeve (ground). Patch (Channels 1~8 & Aux): These 3-conductor TRS ¼" phone insert jacks are for connection of other BIAMP products or external devices to the individual input channels. Patch jacks are preChannel Level, and are wired Tip (send), Ring (return), and Sleeve (ground). Certain BIAMP products require TRS ¼" phone cables for connection. Other devices may require special `Y' cables. If a pre-Channel Level direct output is desired, connect to Patch with Tip & Ring (send) and Sleeve (ground). Input (Channels 1~8 & Aux): These plug-in barrier strips provide the balanced mic/line Inputs to the mixer (Channels 1~8 only). Input isolation transformers (model IT-A) are available as a user installed option (see Options on pg. For balanced connection, wire high (+), low (-), and ground ( ). For unbalanced connection, wire high (+) and ground to both ( ) & (-). Phantom power (+24VDC) is available (see DIP Switches below), with +48V phantom power as an option (model 48VPS) (see Options on pg. Potentiometers are wired high (V), wiper (C), and low ( ). Ramp voltage is wired positive (C) and ground( ). The Remote port of the 801 SERIES SERIES mixer must be enabled before remote control of output level is possible (see Master DIP Switches on pg. Remote control does not change physical settings on the 801 SERIES SERIES mixer, it only attenuates from the maximum level settings established at the mixer. 48 Volt Phantom Power: The 801 SERIES SERIES mixer provides +24 Volts DC phantom power for condenser microphones (see DIP Switches on pg. Most modern electret condenser microphones can operate using a wide range of phantom power voltages (typically 9~52VDC). Only rare circumstances (such as older or specialized microphones) will require anything greater than the standard +24VDC phantom power. However, if these circumstances should arise, an optional +48 Volt DC phantom power supply is available (model 48VPS). To install the optional 48VPS: simply separate the AC power cord at the `in-line' DIN connector near the 801 SERIES SERIES chassis. Insert the 48VPS `in-line' with the power cord, mating the DIN connectors of the 48VPS to the appropriate gender DIN connectors from the 801 SERIES SERIES chassis & the wall-mount power transformer. Phantom power is automatically converted to +48 Volts DC when selected at inputs. [. . . ] Playback signal from VCR is connected to the Aux input on the bottom unit, which is set to sum the stereo signal. Channel 8 on the bottom unit is set for priority & duck aux, which both prevents Channel 1 override of this input and allows signal in Channel 8 to cause ducking (attenuation) of the Aux input (VCR) signal. 6 APPLICATIONS 8-Input / 4-Output Zone Paging & Background Music System emergency mic zone routing & override switches from mics paging mics background music sources 801 SERIES SERIES BIAMP SYSTEMS an affiliate of Rauland Borg Corp. 27V 50/60 Hz main patch patch ~ input LR patch input patch input ON patch input ON patch input ON patch input ON patch input ON patch input ON patch input ON DC out main out stack in remote vc ON ON ON ±12VDC pad priority phantom duck aux hp filter pad priority phantom duck aux hp filter pad priority phantom duck aux hp filter pad priority phantom duck aux hp filter pad priority phantom duck aux hp filter pad priority phantom duck aux hp filter pad priority phantom duck aux hp filter MADE IN U.
