Resistor in cable: resistance value?
#589610 - 10/03/08 08:17 PM
I sometimes patch my radio into my mixer, but the signal is much too strong, and even when
the channel is muted, I can still barely hear it (crosstalk?). I intend to make a custom
cable with resistors to reduce the level, any idea of a starting value to try? cheers, Plat

Not sure about wiring a pot into a cable though, although a mini trim pot - the type
adjusted with a screwdriver rather than a knob - might fit into a roomy jack.
I go for the trim pot approach when I take the speaker outputs from circuit bent toys.
I've thought about building a general purpose attenuator, a volume pot in one of those
little plastic boxes with an in and out jack.
In his book Handmade
Electronic Music, Nicolas Collins recommends 10k and 1k resistors to attenuate a hot
signal to line-ish level. In his schematic the 10k one goes in series with the output and
the 1k to ground. I've never tried this though.
I'm curious as to why the
radio output is so hot anyway - surely a headphone/line out wouldn't overload a mixer?
