I would like to ask if someone could duplicate a problem I am having. Take the Pulsar analog in and patch it to a Dynamic Mixer ch1 set to mono. Insert a Compressor M into the first slot and the PEQ4 M into the second slot. Patch the Dynamic mixer out to Pulsar analog out(for monitoring duh). If you hear sound you don't have the same problem. If you have to put the PEQ4 M in bypass to hear sound then you have the same problem I just ran across. Look out it could be a BUG!!!
