fx send on the 246

[22tape]

hey guys. a really basic question:

how do you setup a send/return effect on the 246? i want to use a reverb unit and mix the amount of reverb and original signal for each channel. in the manual is say that i can do this by using Line B on channel 5 and 6....but the Line B inputs are RCA....how would that work with the out of the reverb unit? plus, wouldn't the reverb only be mixed on 5 and 6? i'd like to be able to mix the reverb across all channels.

thanks a bunch!
