  If your Boulder Amplifier shows no power indication, there are several potential causes: * The power switch might not be turned on, in this case, turn on the power switch. * The power amplifier might not be plugged in. Ensure it's connected to an AC outlet. * The home circuit breaker could be tripped. If this is the case, have the line voltage checked.

  If your Boulder Amplifier has an amber power indication but you're not hearing sound from one channel, consider these possibilities: * There may be no signal from one channel of the source. Check the source controls, cables, and connections. * One channel might be muted by the balance control. Re-center the balance on the preamp. * There might be no signal going out to the power amplifier. In this case, check the connections to the power amp.
