T SENSITIVITY OUTPUT LEVEL NOTE The Input Level control A should always be set such that the Limit LED B flashes on the program material peaks Failure to do so will result in increased operating noise at the output of the unit The Output Level control W should always be set to provide the appropriate signal level for the return unit connected to the output of the processor Failure to do so will result in increased noise at the output of the unit AUTOMATIC BANDWIDTH CHANGES NOTE The internal microprocessor automatically selects the appropriate bandwidth for any particular delay setting This is done in real time and results in modifications to the sound of the effect any time the delay time is changed If this is done via a preset change the PEP 4000 will automatically mute the output to avoid any displeasing sounds If this is done using the Increment or Decrement keys K there will be a slight modification to the effect sound for a short time until the memory is cleared This is not amalfunction The bandwidth is modified at 1024 milliseconds and again at 2048 milliseconds if the delay time is being increased The bandwidth is modified at 1023 milliseconds and again at 511 milliseconds if the delay time is being decreased MODIFIED PROGRAM PRESETS NOTE A program preset can be modified at any time by using any of the front panel controls When any control s position is changed the LED for the preset in use will begin to flash indica
