I just set the gains on my amplifiers and found that the DD1 unit did not pick up a signal on the left channel, but did on the right channel. After some experimentation I found that it would pick up the signal if I used the speaker connection labeled negative on the left channel. It does this on both amps. Could the amplifier be labeled incorrecly? it is a 2 channel Crunch amp. Now this has me wondering about the speaker phasing. Anyone ever run into something like this?
