SONAMP DSP 8-130 MULTI-CHANNEL POWER AMPLIFIER INSTRUCTION MANUAL
Protection Circuitry and LEDs
The Sonamp amplifiers have a multi-stage protection system to
prevent damage to your amplifier and speakers.
Amplifier Channel Protection DSP 8-130
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.
Amplifier Channel Protection Indication DSP 8-130
On the front panel of the Sonamp DSP 8-130 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 DSP 8-130
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.
Rack Ear Installation DSP 8-130
The DSP 8-130 ships with two rack ears. Unscrew the four Phillips
head screws (M4 x 0.7 pitch x 10mm long) found on each side of
the left and right forward section of amplifier. Use these screws to
connect the included rack ears to the amplifier (see Figure 15).

Amplifier Stacking
The DSP 8-130 is capable of being directly stacked with the
feet removed (see Figure 16) for use in low to moderate output
applications. For high-output applications, it is recommended to
leave at least 1U space between amplifiers for increased ventilation.
It is not recommended to stack more than three amplifiers high
without spacing.
Shelf Mounting
If shelf mounting, attach the four included feet by screwing them
into the threaded openings, no tool is required.
