CHANGING THE MIDI CHANNEL, SELECTING THE PROGRAMS:
The RC-1 comes from the factory configured for MIDI channel #1. You may change the MIDI channel identification of the RC-1
by the use of four solder jumpers on the bottom of the RC-1 circuit board. See the documentation included with the RC-1 for
how to reconfigure its MIDI channel.
Assuming your RC-1 will remain on MIDI channel 1, we need to configure one of the 6200’s channels to respond to an RC-1
on MIDI channel 1.
1. Press the HOME button to ensure that we are starting from the top.
2. Press the NEXT button once.
3. Turn the ADJUST knob clockwise until the display reads “Section to Edit, - Setup Menu -”.
4. Press the NEXT button once.
5. Turn the ADJUST knob clockwise until the display reads “- Setup Menu -, -- External Controls --”.
6. Press the NEXT button five times and the display should read “RC-1 Remote Control, CH 1 MIDI Channel: 1”.
8. This setting is correct for an RC-1 set to MIDI channel 1 destined to recall programs on the 6200’s channel 1. If your RC-1
is set to a different MIDI channel, turn the ADJUST knob to select the appropriate MIDI channel.
9. Press the NEXT button once.
10. The display should read “RC-1 Remote Control, CH 1 First Pgm: 1”. This means that button one on the RC-1 will recall
program 1 on the 6200. This gives you access to programs 1-11 from the RC-1. You can offset that access range by turning
the ADJUST knob to change the “CH 1 First Pgm” setting. For example, if you set the first program to be 101, then the RC-
1 will have access to program 101 through 111.
11. Press the HOME button when finished.
OPERATION:
Push the button in the upper left corner of the RC-1. This is labeled PROGRAM 1. The LED next to the push-button will light.
Verify that the 6200 has loaded program 1 on channel 1. The HOME screen on the front of the 6200 will display “CH1:Program
1”. Push several other buttons on the RC-1 and verify that the 6200 loads the corresponding program. Please press only one
button at a time.
You may write, in pencil please, your own identification for programs 1 through 11 on the spaces provided on the RC-1
Remote Control. If you will faithfully use pencil, the names are easily erased when changes become necessary. Ball-point pen
markings can usually be removed with denatured alcohol. Beware: unlike radio station staff, names entered with permanent
markers usually remain forever. A wise alternate label might be some sort of stick-ons produced by a label making machine.
Note: BYPASS (PROGRAM 0), in the lower right corner of the RC-1, invokes the DSP Bypass function of the 6200. This can
be used as a quick way to A/B before and after processing (EQ, compression, etc.) or to simply bypass the DSP functions.
This bypass still utilizes the A/D and D/A stages of the 6200. For a true hardware relay bypass, see the following section.
NEED A LONGER CABLE?:
The RC-1 uses a shielded cable of seven #22 gauge wires. You may build a longer cable, or an extension cable, with 7-pin
DIN connectors and shielded 7-conductor cable. If you build your own remote cable of a length longer, or shorter, than the one
supplied, both connectors will be male. If you choose to build an extension cable for the RC-1, please use one male and one
female 7-pin DIN connector. Pin #1 connects to pin #1 on the opposite end. Pin #2 connects to pin #2, etc. Symetrix does not
offer extension cables, or cables of different lengths.
AN RC-1 FOR EACH 6200 CHANNEL:
As you know by now, the 6200 is a two channel device and each of those channels can operate independently providing two
discreet processors in one box. Unfortunately, there is only one MIDI/RC-1 jack. So, if you would like to have multiple RC-
1’s (or MIDI devices) connected to the 6200, a third device will be required. The prime example is where one RC-1 controls
channel 1 of the 6200 and another RC-1 controls channel 2. The third device required is known as a MIDI merge box. They
are essentially mixers for MIDI data streams with multiple MIDI inputs and one output. Using a MIDI merge box will require you
to power the RC-1’s locally via their 9 VDC inputs as described on the previous page. Most MIDI devices do not have the 7-pin
jack that the RC-1 does, so power from the 6200 will not be possible.
NOTE: Symetrix does not make, sell, recommend or test MIDI merge boxes. Please refer to your friendly dealer for any such
products currently available.
