STEREO PROGRAM INPUT CONTROLS

HIGH: This control adjusts the high frequency equalization (Treble) for the channel. High equalization is a shelving type fiiter, which provides +/-12dB of gain adjustment for frequencies above 10kHz.
MID: This control adjusts the middle frequency equalization (Mid) for the channel. Mid equalization is a peaking type filter, which provides +/-6dB of gain adjustment for frequencies centered around 1.5kHz.
LOW: This control adjusts the low frequency equalization (Bass) for the channel. Low equalization is a shelving type filter, which provides +/-12dB of gain adjustment for frequencles below 75Hz.
ASSIGN TO CUE: This switch, when depressed, sends channel signal to the Cue section for monitoring at the Headphones and the Control Room outputs. Cue is useful for listening to individual channel signals without affecting the output-mix. Cue is pre-fader, which- permits listening to a channel even when the channel Level control is tuned down, Cue is a monaural sum of the Stereo Program Input signal.
PEAK INDICATOR: This red LED indicates when signal level within the channel has reached +12dB (9dB below clipping). In most applications this LED will never light. However, if it comes on for more than just occasional peaks in signal level, reduce the signal level of the device feeding into the channel..
SIGNAL PRESENT INDICATOR: This green LED indicates when signal level within the channel is above -12dB (normal signal level). If the input signal is strong enough, this LED will remain lit when signal is present at the channel input.
LEVEL: This control adjusts the level of channel signal being sent to the Main Stereo Output and Tape Output sections. The setting of this control has no effect on signal level at the Peak and Signal Present Indicators, or the Assign to Cue switch. The Stereo Program Input channels may be assigned to the Mono Output section as well (see Options and Accessories on page 9).

MONO/MICROPHONE INPUT CONTROLS

HIGH: This control adjusts the high frequency equalization (Treble) for the channel. High equalization is a shelving type fiiter, which provides +/-12dB of gain adjustment for frequencies above 12kHz.
MID: This control adjusts the middle frequency equalization (Mid) for the channel. Mid equalization is a peaking type filter, which provides +/-12dB of gain adjustment for frequencies centered around 2.5kHz.
LOW: This control adjusts the low frequency equalization (Bass) for the channel. Low equalization is a shelving type fitter, which provides +/-12dB of gain adjustment for frequencies below 100Hz.
ASSIGN TO CUE : This switch, when depressed, sends channel signal to the Cue section for monitoring at the Headphones and Control Room outputs. Cue is useful for listening to individual channel signals without affecting the output mix. Cue is pre-fader, which permits listening to a channel even when the channel Level control is tured down.
PEAK INDICATOR: This red LED indicates when signal level within the channel has reached +12dB (9dB below clipping). For best performance, use the Trim control and Pad switch (both on the rear panel) to adjust gain so that the Peak Indicator flashes only on occasional peaks in signal level.
SIGNAL PRESENT INDICATOR : This green LED indicates when signal level within the channel is above -12dB (normal signal level). Once the Trim control (on the rear panel) has been adjusted, this indicator will remain it when signal is present at the channel input,
LEVEL: This conirol adjusts the level of channel signal being sent to the Mono Output section. The setting of this control has no effect on signal level at the Peak and Signal Present Indicators or the Assign to Cue switch. The Mono/Microphone Input channels may be assigned to the Stereo Main Output and Tape Output sections as well (see Options and Accessories on page 9).

MONITOR SECTION CONTROLS

TAPE LEVEL : This control adjusts the level of signal being sent to the Left and Right Tape Output jacks on the rear panel. The Tape Outputs normally contain only signals from the Stereo Program Input channels. However, signals from the Mono/Microphone Input channels may be added to the Tape Outputs by moving an internal programming jumper (see Options and Accessories on page 8).
MONITOR SELECT (Main or Cue) : When released, this switch selects the signals from the Main Stereo Output section to appear at the Control Room Output and Headphones sections. When depressed, this switch selects the monaural Cue signal to appear at the Control Room Output and Headphones sections.
CONTROL ROOM LEVEL : This control adjusts the level of signal being sent to the Control Room Output terminals on the rear panel. The Control Room signal source is determined by the Monitor Select switch.
HEADPHONES SECTION: The Headphones control adjusts the level of signal being sent to the Headphones jack. This output s designed to drive 600 Ohm headphones. However, it may be connected to a separate sound system using a special “Patch” cable (see Options and Accessories on page 9). The Headphones signal source is determined by the Monitor Select switch,

OUTPUT SECTION CONTROLS

METER SELECT : When released, this switch selects the stereo signal from the Main Stereo Level control to appear at the respective Left and Right Level Meters. When depressed, this- switch selects the sum of signals from all active channel Cue switches to appear at the Left Level Meter and selects the signal from the Mono Level control to appear at the Right Level Meter.
MONO LEVEL : This control adjusts the level of signal being sent to the Mono Output terminals on the rear panel. The Mono Output normally contains only signals from the Mono/Microphone Input channels. However, signals from the Stereo Program Input channels may be added to the Mono Output by moving an internal programming jumper (see Options and Accessories on page 9).
MAIN STEREO LEVEL : This control adjusts the level of signal being sent to the Main Stereo Output terminals on the rear panel. The Main Stereo Outputs normally contain only signals from the Stereo Program Input channels. However, signals from the Mono/Microphone Input channels may be added to the Main Stereo Outputs by moving an internal programming jumper (see Options and Accessories on page 8).
LEVEL METERS: These 10-segment LED displays normally indicate signal levels at the Main Left and Right outputs. However, if the Meter Select switch is depressed, the Left Level Meter will instead display signal level from the Cue system and the Right Level Meter will display signal level at the Mono output, When the red +12dB indicators flash, 11dB of headroom remains before clipping at the balanced outputs. Headroom is reduced by 6dB when these outputs are used unbalanced.
These meters are peak reading, with “0” referenced to +4dBu.
POWER SWITCH and INDICATOR: When the Power Switch is turned on, the green LED indicates power is applied to the mixer.

STEREO PROGRAM INPUT CONNECTORS

INPUTS L & R (Barrier Strip): These 6-terminal Barrier Strips are for connection of stereo signals from ling-level devices such as tape decks, videotape players, and Compact Disc players. The Input terminals provide a balanced and floating input,
which allows connection of either balanced (3-conductor) or unbalanced (2-conductor) signals. For balanced use, connect with high o (+), low fo (), and ground to (gnd). For unbalanced use, connect with high to (+) and ground to (-). This provides a floating input, with no direct connection to signal ground. If a signal ground reference is necessary, connect ground o the (- and (gnd) terminals. Monaural signals may be connected here,
but must be connected to both the L & R inputs to be centered.
INPUTS L & R (RCA Phono): These RCA Phono jacks are wired in parallel to the Input Barrier Strips, with Tip being high (+) and Sleeve being low (). Therefore, they too will accept either balanced (3-conductor) or unbalanced (2-conductor) signals. For balanced use, connect with high to Tip and low to Sleeve. For unbalanced use connect with high to Tip and ground to Sleeve. In both cases, this provides a floating input, with no direct connection to signal ground.
If a signal ground reference is necessary for balanced use, connect ground to the (gnd) terminal at the Barrier Strip for the respective input.
If a signal ground reference is necessary for unbalanced use, connect the () & (gnd) terminals together at the Barrier Strip forthe respective input. Monaural signals may be connected here, but must be connected to both the L & R inputs to be centered.
CAUTION: To avoid increased distortion, do not attempt to utilize both the Barrier Strip and RCA Phono connectors simultaneously on the same channel. Only. one stereo input signal should be connected to a channel at any time.
PATCH L & R: These 3-conductor 1/4″ Phone jacks are post- equalization /pre-Level insert points. They are for connection of outboard signal processing devices to the respective channels, and are wired with Tip being the send (output), Ring being the return  (input), and Sleeve being ground. When connecting  devices other than ADVANTAGE products, special “Patch” cables should be used (see Options and Accessories on page 9) Some ADVANTAGE products, however, can be connected using standard balanced (3-conductor) 1/4′ Phone cables. Patch jacks may also be used as pre-Level direct outputs to feed other devices such as tape recorders. To accomplish this, without interrupting channel signal, connect to Patch jacks with Tip and Ring (wired together) being the send  +) and Sleeve being ground. A standard unbalanced (2-conductor) 1/4″ phone cable may be used to extract signal from the Patch- jacks. However, this will interrupt the channel signal before it reaches the Level control. The Left and Right Patch jacks on each channel function independently from each other.

MONO/MICROPHONE INPUT CONNECTORS

MONO/MIC INPUTS : These 3-pin XLR jacks provide balanced Mic or Line input to the channels. The inputs are electronically balanced, using discrete transistor differential circuitry. There is internal +15 Volt’ Phantom Power available for operation of condenser microphones (see Phantom Power below). If +48Volt Phantom Power is required, an external power supply is available (see Options and Accessories on page 9). The input jacks are wired to the DIN standard, with Pin 2 being High (+), Pin 3 being Low (-), and Pin 1 being Ground.
If unbalanced input is desired, connect to the Input jack with Pin 2 being High (+) and Pins 1 and 3 being Ground. 30dB PAD: These switches, when depressed, reduce channel input signal level by 30dB. Use the Pad switch when channel input signal levels exceed the normal operating range of the TRIM control (below).
TRIM: These screwdriver adjustable controls set channel gain to compensate for different input signal levels. For best performance, adjust the Trim controls so the front panel Peak Indicators flash only on occasional peaks in.channel signal level. These controls are factory set for 40dB of gain, and may not require adjustment when using microphones of -55dBm sensitivity.
PHANTOM POWER: These switches, when depressed, apply +15 Volt Phantom Power to the Mono/Mic input jacks, for operation of condenser microphones and direct boxes. An optional +48 Volt Phantom Power supply is available (see Options and Accessories on page 9). Normal Low-impedance microphones will not be affected by this voltage. The red LED indicator remains lit while Phantom Power is on.
CAUTION: Do not assign Phantom Power to channels being used for line level or unbalanced inputs. To avoid possible damage to the sound system, always tumn levels down before switching Phantom Power or making connections to the mixer.
PATCH: These 3-conductor 1/4″ Phone jacks are post- equalization/pre- Level insert points. They are for connection of outboard signal processing devices to the respective channels, and are wired with Tip being the send (output), Ring being the return (input), and Sleeve being ground. When connecting devices other than ADVANTAGE products, special “Patch” cables should be used (see Options and Accessories-on page 9) Some ADVANTAGE products, however, can be connected using standard balanced (3-conductor) 1/4′ Phone cables. Patch jacks may also be used as pre-Level direct outputs.to feed other devices such as tape recorders. To accomplish this, without interrupting channel signal, connect to Patch jacks with Tip and Ring (wired together) being the send  +) and Sleeve eing ground. A standard unbalanced (2-conductor) 1/4′ Phone cable may be used to extract signal from the Patch jacks. However, this will interrupt the channel signal before it reaches the Level control.

MASTER CONNECTORS

CONTROL ROOM OUTPUTS: This 3-terminal Barrier Strip provides an unbalanced stereo output for connection to line level devices such as monitor amplifiers. Depending upon the setting of the front panel Monitor Select switch, these outputs contain either the main stereo signal (pre-Left & Right Patch) or Cue signal from the channel Assign-to-Cue switches. This Sarrier Strip provides left & right signal terminals and one common ground terminal.
TAPE OUTPUTS L & R: These RCA Phono jacks provide an unbalanced stereo output for connection to line level devices such as tape recorders. Normally these outputs contain Stereo Program signals only. However, Mono/Microphone signals may be added (see Options and Accessories on page 9).
OPTIONAL EXTERNAL 48V PHANTOM POWER: (See Options and Accessories on page 9).
DC OUT: This modular jack provides +/-15 Volts DC (100mA max.) to power external devices. Contact Biamp Systems for technical data and information oh associated products.
MONO OUTPUT: This 3-terminal Barrier Strip provides a balanced monaural output for connection to line level devices such as sound system amplifiers. Normally this output contains Mono/Microphone signals only. However, Stereo Program signals may be added (see Options and Accessories on page 9): For balanced use, connect with high to (+), Low fo (), and ground to (gnd). For unbalanced use, connect with high to (+) and ground to both () & (gnd).
WAIN STEREO OUTPUTS: This 6-terminal Barrier Strip provides a balanced stereo output for connection to line level devices such as sound system amplifiers. Normally these outputs contain Stereo Program signals only. However, Mono/Microphone signals may be added (see Options and Accessories on page 9). For balanced use, connect with high to (4), Low to (-), and ground to (gnd). For unbalanced use, connect with high to (+) and ground to both (-) & (gnd).
LEFT, RIGHT, & MONO PATCH: These 3-conductor 1/4″ Phone jacks are pre-Level insert points. They are for connection of outboard signal processing devices to the respective outputs, and are wired with Tip being the send (output), Ring being the return (input), and Sleeve being ground. When connecting devices other than ADVANTAGE products, special “Patch” cables should be used (see Options and Accessories on page 9) Some ADVANTAGE products, however, can be connected using standard balanced (3-
conductor) 1/4″ Phone cables. Patch jacks may also be used as pre-Level direct outputs to feed other devices such as tape recorders.
To accomplish this, without interrupting output signal, connect to Patch jacks with Tip and Ring (wired together) being the send (+) and Sleeve being ground. A standard unbalanced (2-conductor) 1/4′ Phone cable may be used to extract signal from the Patch jacks. However, this will interrupt the output signal before it reaches the Level control.
AC FUSE: Replace only with fuses of the exact value and type (.5A SB for 115V operation or ,25A SB for 230V operation).
VOLTAGE SELECTOR SWITCH: This switch is factory set to 115V” for operation with nominal line voltages of 110-120VAC. For operation with nominal line voltages of 220-240VAC, set this switch to 230V” and replace the AC Fuse with a .25A SB fuse (accessory item included with unit).
AC POWER CORD: This cable is for connection to three prong grounded AC outlets. CAUTION: Do not remove or defeat the AC ground prong on the plug, as this constitutes a shock hazard.
