Peavey XR 680C User Manual

Specifications and Main Features

Balanced Low Impedance Input: Connector with XLR receptacle for low level sources like microphones having low impedance.

High Impedance Input Jack: A 1/4” phone plug jack that allows the use of high level sources such as high impedance microphones.

Main Output: Signal from the main mix after the equalizer is provided.

Monitor Output: This output supplies the signal to an external monitor amplifier / speaker system.

Effects Output: These outputs are used to send signals to external devices for processing or applying effects.

Graphic Input: This enables sending signals to the internal graphic equalizer or power amplifier.

Graphic Out: This provides access to the output of the internal graphic equalizer.

Footswitch: Connection for an optional footswitch for turning the reverb on and off.

Auxiliary Input: An input available on the main mixing bus for the return of effects units, additional mixing buses, etc.

Power Amp Input: Fuels the connection of a line level signal to a power amplifier.

Level Control: Adjusts the level of output signals.

Monitor Control: Sets the level of monitor mix on the channel.

Equalizers: Equalizer settings consist of: Low EQ (+15 dB @ 80 Hz), Mid EQ (+12 dB @ 600 Hz), High EQ (+15 dB @ 10 kHz).

Effects Send: Adjusts the drive level of the reverb on the channel.

Phantom Power On/Off: Provides 48V DC phantom power for all channels.
Master Gain: Controls the general loudness of the entire system.
Master Monitor: Controls the loudness of any given monitor mix.
Effects Master: Controls the effects level sent to internal reverb and supplied to the Effects Out jack.
Tape Out Level: Adjust the signal strength coming from the Tape Out jacks.
Tape/Aux Level: Adjust the strength of signals connected to the Tape In jacks or to the Auxiliary input.
9-Band Graphic Equalizer: Provides equalization of +15 dB at each center frequency.
Power Requirements: 800 W, 110 V AC, 50 or 60 Hz.
Rated Power & Load: 210 W RMS at 4 ohm loads and 300 W RMS at 2 ohm loads.
Frequency Response: +0, -1 dB from 10 Hz to 30 kHz @ 200 W 4 ohm load.
Total Harmonic Distortion: Better than 0.1% at full power with the average better than 0.05%.
Input Sensitivity: 1 volt RMS for 200 watts into 4 ohms.
Damping Factor: More than 100 at 1KHz, 4 ohm load.
Hum & Noise: Noise levels of less than 90 dB at 200 watts within the frequency range of 20 Hz to 20 kHz.
Slew Rate: Better than 15 volts per microsecond.

This component is to be used with low level sources with an XLR output or a low impedance microphone.

The use of Low and High Impedance inputs on one channel is mutually exclusive.

You need to plug it into a power supply that has 120 V AC, 50/60 Hz printed on it.

The effects output is for sending signals to external devices for doing effects or processing the signals.

The overall loudness level is set with a Master Gain adjustment.

This switch enables all channels with 48V DC phantom power that is needed for professional use of condenser type microphones.

What is the level of the maximum output signal before the auxiliary output distortion?

The level of the maximum output signal before distortion at the main output is +18 dBV.

Is it possible to change the audio frequencies?
Certainly, the machine includes adjustable active bass, middle, and treble sound controls.
What do I do if the fuse is blown?
Change the fuse to the same type and rating in an effort to prevent damage to the equipment and the loss of the warranty.
What role does the graphic equalizer serve?
In terms of sound, the 9-band graphic equalizer has equalization of center frequencies of 15 dB at every center frequency.
