External Program Recall

Programs may be recalled externally using a user-built 9-pin interface on the PROGRAM CONTROL port or by using an 

AirTools RC-1 MIDI controller. Additionally, any generic MIDI controller which can send MIDI Program Change messages will 

work.

PROGRAM CONTROL:

The PROGRAM CONTROL port is a standard 9-pin D-sub connector which allows program loading on 

each channel using standard contact closures. Interfacing with the PROGRAM CONTROL port allows 

the user to integrate the 6200 into a purpose-built work surface.

Until support for a remote LCD is fully implemented, program scrolling/loading is a blind process. There is no 

front panel indication of any actions on the PROGRAM CONTROL port.

MIDI/RC-1 IN:

The 6200 responds to MIDI Program Change messages from the AirTools RC-1 Remote or from any MIDI device capable of 

sending MIDI Program Change messages. The RC-1 allows direct recall of up to 11 programs as well as the ability to enable/

disable the DSP BYPASS function.

The RC-1

The RC-1 does not provide selection or change of any individual processing parameters within the 6200’s programs. It 

merely selects and loads up to 11 sequential programs (plus DSP Bypass). 

Changes to the 6200’s processing parameters must be made at the 

unit’s front panel or by using the optional 6200 Designer software. There 

is no button lockout or other security feature provided on the RC-1. If 

you accidentally hit one of the buttons, you will accidentally change the 

processing program on the 6200.
The RC-1 connects to the 6200 with the included 25-foot, 7-pin DIN cable. 

The 6200 and RC-1 exchange MIDI information on pins #2 and #3. The 

6200 provides power for the RC-1 on pins #1 and #7. Pin 

#7 is +V; pin #1 is ground. To preserve compatibility with 

other MIDI devices, the remaining pins on the connector are not used. 

If you connect the 6200 to a MIDI 

controller other than the RC-1, make sure you use a cable which does not have Pin #7 connected.

Caution:

 The RC-1 includes a jack for an optional 9 VDC power supply providing at least 30 mA (not 

supplied). If you use the RC-1 with the 6200 and the supplied 7-pin DIN cable, the RC-1 takes its power 

from the 6200. 

No external power supply is required when using the RC-1 with the 6200 and the 

provided cable.

 The optional 9 VDC connection allows you to use the RC-1 with other MIDI controlled 

devices which to not supply power. NOTE: Symetrix does not make, sell or recommend a power supply.

You will notice that none of the LEDs on the RC-1 are lighted when it is first plugged in. This is normal; the LEDs serve as tally 

lights indicating which button was pushed last. The LEDs do not provide positive confirmation from the 6200 that the program 

selected was loaded by the 6200. The RC-1 will not reflect a change in program selection made at the front panel of the 6200. 

The LEDs on the RC-1 serve as reminders of which button on the RC-1 the user pressed last. (MIDI communication is one-

way, from RC-1 to 6200.)
