Dual digital delay
In quasi-stereo mode, two independent delays operate on the same sound from 1 ms to the maximum value. In true stereo mode the two channels are completely separate.  The maximum value of delays depends upon selected bandwidth : 1 200 ms for 5 KHz, 600 ms for 1 0 KHz, 300 ms for 20 KHz. In option additive memories can upgrade delay up to 5000 The D.H.M. 89 B2 offers an unique feature which allows a continuous variation of delay without doppler effect nor switching noises. So that it is possible to change delay during operation without audible effects.

Dual echo
By association of dual delay and feedback.

Dual pitch shifting
From – 2 to + 1 octave. Sophisticated micro-computer operates phase coincidence of joining points and eliminates glitches. The serial delay is adjustable.

Dual automatic arpeggio is a pitch-increasing or decreasing echo.

Dual reversed sound: Electronic equivalent of a magnetic tape running reversed. Reversed sound itself can be pitch-shifted.

Dual memory latch mode
Memorised sound can repeat indefinitely. The two borders of repeating sound are continuously selectable, as wall as reading sense and pitch ratio.
