User manual BIAMP 801 SERIES

[. . . ] 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). Trim (Channels 1~8): These screw-driver adjustable controls set the channel gain (0~60dB) to compensate for different input signal levels. For best performance, adjust these controls so the channel +10 indicators flash only on occasional peaks. [. . . ] 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. 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 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. The Aux input accepts either balanced mono line input or unbalanced stereo line input (see DIP switches below). Aux input cannot accept mic input signal, or the optional input isolation transformer, and does not provide phantom power. 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. NOTE: The 801 SERIES SERIES chassis must be disassembled before installing input/output transformers: 1) remove top panel (2 screws at bottom of each side panel; 1 screw at top-center of front panel; 1 screw at top-center of rear panel). 2) remove screws from front panel (2 screws at each end; 1 screw at bottom-center). 3) remove screws from rear panel (2 screws near Main Out/Remote connectors). 4) remove nuts & washers from rear panel (10 nuts & washers on Channel & Main Patch jacks). 5) remove mounting screws from circuit board (9 screws in front of input connectors; 2 screws behind channel 3 Level & master Treble controls). 6) gently pull circuit board forward (front panel comes forward; connectors exit rear panel). 7) rotate front panel/circuit board upward, away from chassis (leave rear portion of circuit board in chassis, being careful not to strain power cord connections). Input Transformers: To install input transformers (see diagram on next page): 1) locate the transformer positions on the circuit board (circle area located in front of input connector & DIP switches on each channel). [. . . ] Tone Out is also assigned on the bottom unit, to avoid redundant controls. 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.
