Peavey 4000 User Manual

User is encouraged to try to correct interference by reorienting antenna, relocating equipment, or moving away from receiver.

User should consult a dealer or radio-television technician for additional suggestions.

Mentions a helpful booklet from the FCC for identifying and resolving radio-TV interference problems.

Provides remotely-controlled digital audio processing for musicians and recording engineers.

Offers continuously-adjustable delay settings with computer-controlled frequency bandwidth tracking.

Designed for total compatibility with Peavey MIDI Program Series and other MIDI products.

Sets input sensitivity for optimum matching with input signal; affects MIDI receive channel on power-up.

Indicates minimum signal level necessary for operation, 12 dB below clipping onset.

Indicates 6 dB headroom remaining; lights occasionally during peaks, not prolonged.

Adjusts regeneration for flange effects and decay rate for slap-back echo effects.

Adjusts the depth or width of the LFO modulation sweep.

Adjusts the frequency or sweep rate of LFO modulated effects, 0.1 Hz to 10 Hz.

Sets the mix ratio for the delay and dry output signal levels.

Illuminates when the PEP 4000 has acquired a sync or trigger signal from an external source.

Flashes at the repeat rate of the delay line, providing a visual tempo strobe.

Four-digit LED display showing numeric representation of delay time or MIDI receive channel.

Used to increase or decrease the displayed delay time in specific increment steps.

Selects between Bank A and Bank B for program storage and recall.

Used to recall or store programs within the processor's memory.

Enables Sync mode for synchronizing delay time to an external trigger source.

Enables Fade mode for delayed signal to fade out over original dry signal.

Changes the phase of the feedback signal by 180 degrees.

Enables a low-pass filter in the feedback path to eliminate noise regeneration.

Enables Hold function for continuous replay of a frozen digital signal.

Bypasses the PEP 4000, disabling any effect in use.

Supplies AC power to the PEP 4000; saves last settings in memory upon power off.

1/4" jacks providing in-phase and out-of-phase delayed signals mixed with dry signal.

Selects maximum signal level available at output jacks (+0 dBm or -20 dBM).

Regulates the level of signals appearing at the Stereo Chorus Output jacks.

Provides external trigger or sync input; TTL compatible, active low.

Standard DIN connector for MIDI controller interface to recall programs.

Auxiliary MIDI output for chaining MIDI-compatible devices.

Stereo 1/4" jack for mono or differential input signals.

Selects input signal sensitivity range (-20 dBM or +0 dBM).

Stereo 1/4" jack for optional dual-button momentary footswitch.
