Does the loop bypass work the way it's supposed to?
I believe it does not, and that's why rev C was so short-lived. I'm working on one now, and the loop has been driving me nuts - it's always on.
Going by the schematic for the rev F (and my experience with rev D), when the loop is in bypass mode, none of it is supposed to be active - the relay (relay 2) completely bypasses the entire circuit, including the loop master. Signal is taken from the channel masters directly to the phase inverter.
When the loop is on, the relay feeds signal from the master volumes into the loop, the returns the signal from the loop master to the phase inverter.
When the loop is set to footswitch, or it's on on only one channel, it works as above when engaged, but when it's not engaged LDRs in the loop bypass the send and return jacks, but the send level control and loop master are still active.
Well, the PCB for rev C is made wrong. All the modes work as intended EXCEPT bypass - the relay never closes to bypass the loop, because they wired up the coil polarity wrong. When the loop selector is in bypass mode, the loop master and send controls are still active.
Can anyone who owns a rev C dispute this? Is your lead master bypassed in any setting?
