Power Switch
The power switch turns the amplifier on and off.
When the Sonance logo on the power switch is lit solid white, the
amplifier has power and is turned ON and ready to operate.
When the Sonance logo is slightly dimmed the amplifier is in
standby mode.
When the Sonance logo on the power switch is blinking white, the
amplifier power supply is in thermal protection. The channel LEDs
will also light red when the power supply is in thermal protect mode.
NOTE: Upon initial power up there will be an approximately 12
second boot up cycle. This is normal.
Input/Output Lights
When each channel is active, the LED will light green as long as a
signal is present.
When the LED blinks red, this is an indication that the channel is
being overdriven.
When the LED lights are solid red this is an indication the amplifier
is in protect mode. While in protect mode the LED lights will
periodically light green to retest the output to determine if the short
has been removed. Protect mode could be caused by a short in the
wire, overheating of the amplifier or possibly an internal problem
with the amplifier.

Protection Circuitry and LEDs
The Sonamp amplifiers have a multi-stage protection system to
prevent damage to your amplifier and speakers.
Amplifier Channel Protection 2-100 & 12-50
If a channel encounters a short-circuit (in bridged mode the
protection circuitry will sense a short circuit across both positive
speaker terminals), or extremely low impedance will cause the
affected channel outputs to automatically mute. The output of
the effected channel will remain muted until the fault has been
corrected. Only the effected channels output will mute, all other
channels will continue to operate normally.
On the front panel of the Sonamp 2-100 and 12-50 amplifiers are
dual color LEDs that illuminate to indicate the current operating
status of each amplifier channel.
When the LED blinks red this is an indication that the channel is
being overdriven.
When the LED lights are solid red this is an indication the amplifier
is in protect mode. While in protect mode the LED lights will
periodically light green to retest the output to determine if the short
has been removed. Protect mode could be caused by a short in the
wire, overheating of the amplifier or possibly an internal problem
with the amplifier.
IMPORTANT: ALLOWING THE AMPLIFIER TO OPERATE WITH
ONE OR MORE CHANNELS IN PROTECT MODE FOR AN
EXTENDED PERIOD OF TIME CAN DAMAGE THE AMPLIFIER.
Amplifier Power Supply Protection 2-100 & 12-50
The amplifier also has protection for the power supply. If the power
supply heat sink temperature exceeds the design maximum, the
protection circuit will activate, disconnecting all channel outputs.
This is indicated by a blinking light on the front panel power switch.
IMPORTANT: ANY TIME THE PROTECTION CIRCUITS ARE
TRIGGERED, UNPLUG THE AMPLIFIER’S POWER CORD FROM
THE WALL OUTLET BEFORE TROUBLESHOOTING.
