What to do

• Be sure power switch is ON.

• Make sure the power cord is fully inserted into the unit and

an AC outlet.

• Be sure the AC outlet is live. Try operating a lamp or other

equipment from the same AC outlet or test the outlet using

an AC outlet tester.

• Amplifier is in the Protect mode:

– Thermal overload: Lower the level of the input signal. Be

sure the amplifier is on a hard, flat surface to aid in heat

dissipation.

– Output is short-circuited: Check output connections/wires.

– Driving too many speakers in parallel: Make sure you

connected no more than two B1 bass modules to one A1

amplifier.

– Impedance is too low: Make sure you connected only one

4-ohm or up to two 8-ohm speakers of other brands.

– Input level is too high: Lower the level of the input signal.

• The red light should no longer illuminate when a fault condi-

tion is removed. In the case of thermal overload, the ampli-

fier may have to cool for a few minutes.

• The input signal is near limit. Lower the input level so the red

light flashes only occasionally, at peak volumes.

• Speaker not connected properly. Check that output connec-

tions are correct and connectors are fully seated.

• Power not connected. Check the power LED. It will shine

BLUE when power is connected and the unit is turned on.

• No signal going into the amplifier. Check input connections

and input level.

• Replace input cable.

• If you are using a

cable (supplied with the A1 amplifier) between the source

device and the A1 amplifier.

• Plug the power cord of the PS1 or source device into the

same AC (mains) power circuit as the A1.
