Mono Delay 3000 - E-Mu 404 Owner's Manual

Mono Delay 3000

A delay line makes a copy of the incoming audio, holds it in memory, then plays it back
after a predetermined time. Long delays produce echoes, short delays can be used for
doubling or slapback effects. Very short delays can be used to produce resonant flanging
and comb filter effects (use feedback). Stereo signals are summed together before
entering the Mono Delay.
There is also a feedback path to send the delayed audio back through the delay line.
When creating echo effects, the feedback controls how many echoes will be produced.
A High Frequency Rolloff filter in the feedback path cuts some of the high frequency
energy each time the audio goes through the delay line. This simulates the natural
absorption of high frequencies in a room and can also be used to simulate tape-based
echo units.
The Wet/Dry mix controls how loud the echoes are in relation to the original signal.
