628

Testing 1, 2, 3 ...
Push the button in the upper left corner of the RC-1. This is labeled PROG #1. The LED next to
the push-button will light. Verify that the 628 has loaded program #1. The MASTER display on
the front of the 628 will display the number 1. Push several other buttons on the RC-1 and verify
that the 628 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.
Note: Program #0, in the lower right corner of the RC-1, is a bypass only position with no audio
processing or equalization. The 628 does not allow user programming of Program 0.
Need a longer cable?
The RC-1s cable 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.
Troubleshooting
The LEDs on the RC-1 do not light after a button is pushed.
1.) The RC-1 is not receiving power. Are the DIN connectors firmly seated in their
sockets on the RC-1 and the 628?
2.) Is the 628 operating? The RC-1 takes its power from the 628.
3.) If you use the RC-1 with a MIDI device other than the 628, you must provide an
external 9 VDC power supply. This plugs in next to the remote control cable on the RC-1.
A LED on the RC-1 lights after a button is pushed but the 628 does not select and load the
requested processing preset.
1.) The RC-1 is not communicating with the 628. Are the DIN connectors firmly seated on
each end of the cable?
2.) Has the 628s MIDI channel been changed to anything other than Channel #1?
3.) Has your remote control cable been damaged?
The RC-1 loads any processing preset, #1 through #11, except one. For example: When you push
the button for preset #5, the LED on the RC-1 for preset #5 does not light and the 628 does not
switch to preset #5. All other presets buttons operate properly.
1.) The switch for preset #5 (in this example) is broken or contaminated.
2.) Has anyone spilled a soft drink or coffee on the RC-1?
3.) The RC-1s circuit board has been damaged by brute force.
The RC-1 loads all presets properly but one LED on the RC-1 does not light when the corre-
sponding button is pushed.
1.) The LED is defective. Has it been broken or pushed down into the RC-1 chassis?
