Notes Features of the H949:
- Pitch change (with de-glitch circuitry with optional ALG-3 board)
- Time compression/expansion
- Time reversal
- Delay, randomized delay, ADT
- Feedback path with gain and Lo+Hi EQ for space effects
- Flanging
- Repeat

Remote Control:
Provision has been made for control by microcomputer using the IEEE-488/1975 standard interface bus. The HK940 keyboard can be used to control the pitch ratio in discrete musical steps. Option 05 mono keyboard controls one Harmonizer; option 06 polyphonic keyboard controls up to three Harmonizers.
An input is provided to phase-lock the Harmonizer to any synthesizer. A 3 volt peak-to-peak signal is required. The pitch may be varied by a control voltage input in the 5 to 15 volt range (internally selected).

NOTE: XLRs are wired with pin 1=GROUND, pin 2=COLD, pin 3=HOT like most older American gear.
