Power protect The power stage was close to its power limit and to protect your speakers the
amplifier mutes the outputs.
Make sure the impedance of your cable speaker combination is not too low and
the connected speakers are not faulty.
Current protect The power stage was close to its current limit and to protect your speakers the
amplifier mutes the outputs.
Make sure the impedance of your cable speaker combination is not too low and
the connected speakers are not faulty.
Power outage The mains AC voltage had an outage or dropout. To protect your speakers the
amplifier mutes the outputs.
Check your AC cables.
DC protect The output has too much DC voltage and to protect your speakers the amplifier
mutes the outputs.
Check your pre-amp for proper operation and does not have any DC offset at its
output.
BEEP CODES
When the power to the amplifier is turned on with the back panel switch it starts checking the mains voltage
and goes into standby mode. Normal operation and any malfunction at this point is indicated with a series of
beep codes:
1 short beep The amplifier detected mains voltage.
3 short beeps The mains voltage is not within its limits.
6 long beeps The amplifier detected a mismatch between selected voltage (selector switch in
back panel) and actual mains voltage at its power inlet.
Make sure you selected the correct voltage.
