Behringer FCB1010 - Analogue Switching for Rockmaster Preamp
rabidgerry:
Hello again everyone. Told you I was back.
Right the Behringer FCB1010 is quite literally the best large midi controller pedal around in my opinion once you get some Uno firmware installed.
Anyways I recently just found out it had more functionality than I realised. It has two analogue relays that can operate channels on amp/preamps. There are two jacks for this at the back of the pedal. This is really mega useful. However, for some reason I can only get these switches to change between two of my Peavey Rockmasters channels. I think I know why but do not know how I would go about creating a solution.
So what I think I am going to need to do is create some kind of a custom cable. I was wondering would any of you guys know exactly what I would need to do in order to operate all three channels using the on board FCB1010 relays?
Here is a diagram of the rockmaster foot switch which can normally operate all three channels.

So my thinking is, if I was to make a custom cable to work the rockmaster using the behringers relay switches (I believe these jacks are trs) would I need to have some how make a cable that some how excluded the ground and only had the two tip signals?
Also I'm referring to a TRS to Y cable which splits the stereo signal to a separate jack and then plus into each of the relay switches on the Behringer. However I was thinking may be even just a trs to trs type cable plugged into one of the relay jacks might also allow for switching between all three channels on the rockmaster.
Anyone with any advice I would really appreciate it as for the first time in my life I might need a lesser distortion and a to switch back to a heavier distortion. Progress eh :lol:
MarshallJMP:
Do you have a schematic on how the switch 1 and 2 outputs are wired? Couldn't find anything in the FCB manual
rabidgerry:
I'm looking for this information. All I can say for now is they can be switched from momentary to latching. I have them on latching right now. I'll keep digging. Thanks MJMP.

Some guy here actually asking about the same thing as me!! But zero info

This is also speculation and I shall need to test, but I've read on another forum that
--- Quote ---Doesn't the FCB1010 work with two TS cables OR one TRS cable?
I'm pretty sure I read that somewhere.
Too bad I can't find the manual and it doesn't say it on the unit itself (just checked).
I'd check but it would involve spending 5 minutes hooking it up to my Traynor combo (only amp I have with a TRS footswitch input)
But somehow... I could swear that's what I used to do when I was using the Traynor combo live...

and
--- Quote ---If I remember correctly, the 2 outputs on the FCB are in fact of the "TRS" variety (you can use a stereo cable and switch two things at once... provided the receiving amp works this way too)
You can use the two jacks separately with a "mono" cable, or use only one with a "stereo" cable.
If I remember correctly...

So I will need to try just a plain old TRS to TRS type cable into one FCB1010 relay switch to see what functionality I am getting.
MarshallJMP:
So if they are TRS you have 2 switches on switch 1 and on switch 2. But they switch in and out at the same time?

No sure I understand you. You mean both FCB1010 switches operate at the same time? No they are operated independently.
Initially how I tried to use these relays where by running a TRS - Y cable from the rockmaster to the FCB1010.
The TRS end would plug into the Peavey and then the two mono jack I was plugging into each of the switches on the FCB1010.
The functionality I was getting was pretty random. I could never ever reach all three of the channels. Two at best if I recall.
But after reading that info above I'm starting to wonder would a trs - trs cable into one FCB1010 switch allow me to reach all three channels albeit via one footswitch?
Which might not actually be suitable. But then perhaps a custom cable could allow me to switch back using the other fcb1010 switch. I dunno, it's a bit confusing.
Skip to 31 mins in, does this shed any light on the functionality?
