Behringer FCV100

lyle · #1 09-09-2007, 02:19 PM

My buddy just gave me this behringer volume pedal and I cant for the life of me0 figure out how to change the battery in it. It says its a 9v but the power supply suggests a 12 volt power supply?

my second question would be, could I power it with my one spot?

thanks guys.

tryh pushing the pins that hold the pedal inwards and lift the pedal, usually you'll find the battery compartment there.

yeah, its usually where the pedal pivots they're usually black, have a dip in them, use a ballpoint pen to push one in, you should find it in there.

never mind, I figured it out. its not the conventional stomp box "boss" shape its a larger volume pedal. But anyways I still wanna know if a one spot would work? it runs on a 9v but the input says 12v? and theres nothing on the VS website.

if it says 12v go with 12v

I use this pedal as a control voltage pedal to control delay time on my RDS 3.6. You can't power it through the power supply with a OneSpot. I tried being sneaky and using the battery-clip connector where the 9V battery would go, and it worked "sort of." It didn't quite go all the way up to 5V as it did when I powered it with a battery. Maybe the volume section is different, I've never tried it on that mode.

ok well now i got a different question. Can I use this guy to control my boss ph3? if so then how?

Maybe you should check the manual ?

It's a Control Voltage pedal, not an expression pedal, so you can't control the PH3 with it.

edit 10-30-07: WRONG! See below.

Hi- The manual for this pedal is not very good.

Are you certain that this pedal produces a 0-5V signal at output 2? Is it a voltage across the tip and ring?

In other words, this pedal does not require the device being controlled to supply the control voltage? I'd like to sweep the filter cuttoff frequency on my Electrix Filter Factory, which has a CV in (1V per Octave).

As I said, I use it to control a Digitech RDS 3.6, which requires a 0-5V control voltage (i.e., not an expression pedal), and it works. In light of that, I think it would work on your Filter Factory. Yes, the voltage is between tip and sleeve. I've never measured the voltage sweep with a multimeter or anything, but I'm pretty confident that it would work.

Thanks. I'll pick one up and give it a try.

Ok, I have to resurrect this thread in light of some new developments with this pedal. A lot of what I said above turns out not to be true, and I have no idea how the FCV100 or anything else works anymore.

I didn't have my OneSpot at band practice the other day, so I was using this pedal with a battery. I didn't bother to put the battery clip back inside the pedal, so the battery was just hanging out, and at some point the battery fell out, but the pedal continued to work as normal on my RDS 3.6. There was no power going to the pedal, and yet it was still producing a voltage? My bandmates and I (two EEs and ChE) concluded that our music was good enough to defy the laws of thermodynamics.

The RDS 3.6 specifically says in the manual that it needs a 0-5V control voltage, and the FCV100 manual specifically says that it provides a 0-5V control voltage. Is it possible that both are wrong? The RDS 3.6 needs an expression pedal and the FCV100 is one? What a coincidence that would be!

As a result, I decided to test something out. I plugged the FCV into the expression pedal input of my Boss PS-3 with a TIP-SLEEVE cable. The Boss expression pedal is a TIP-RING-SLEEVE and that's what they specify is necessary in all their documentation, so I expected that there was no way it would work. WRONG! It worked, the only thing is, it was backwards: rocking the pedal forward made the pitch go from end voltage to start voltage. However, since you can set the PS-3 to have a higher start pitch than end pitch, I might have just mixed that up, and even if I didn't I could just reverse it to get normal whammy functionality.

Ok, so this has shattered three cornerstones of knowledge that I used to have:
1) FCV100 outputs a 0-5V control voltage
2) RDS 3.6 needs a 0-5V control voltage for remote delay time control
3) Boss expression pedal inputs need TRS voltage divider.

I don't know what to believe anymore!

Thanks for the update Mr. Onion. Strange.
