Operation Manual
Indicators:
Fault Indicator (red):
Flashes when the amplifier output channel has stopped operating.
(See Page 41 Troubleshooting.)
Thermal Indicator (red): Illuminates when the channel reaches 80 degrees Celsius, indicating the onset of protection
compression. If the temprature continues to rise, the amplifier output will shut off at 98 degrees Celsius and remain off until
a safe operating temperature is present.
Clip Indicator (red):
Illuminates when any of the following conditions are present: Onset of audible clipping, clipped signal
detected at input, clipped signal detected at output, engagement of protection circuits.
Level and Signal Indicators (green): Three LEDs indicate signal presence and level as follows: -10 = 10 dB below rated
output -20 = 20 dB below rated output Signal = -40dBU input level
Ready Indicator (green): When this indicator is activated, the amplifier is ready to pass audio.
Cooling Vent Grille
Provides cooling air flow.
Do not block or cover
these vents.
Power Button
Power Ring Indicator (Green) - Illuminates
when the amplifier is plugged into a wall
outlet with acceptable power. NOTE: Power
Button is disabled when AUX port Sleep
circuit is used.
Power Indicator (blue)
Illuminates when the amplifier is ON and
acceptable AC line voltage is present.
Blinks when AC line voltage is outside
±10% range.
Flashes for 4 seconds if Power button
pressed when amplifier is in sleep mode
.
Bridge Mode Indicator (yellow)
Illuminates when when Bridge Mode is
activated for the channel pair, only odd
number channel will be active.
Note: Eight channel model shown. Indications per channel pair are identical for 2 and 4 channel models.
Data Indicator (yellow)
Illuminates when data present on the
data network only. BLU Link
connectivity is not a part of this
indicator.
Cooling Fan Outlet
Outlets for cooling air
flow. Do not block or
cover these outlets.
Auxiliary Connector
3-pin plug-in type connector,
Enables SLEEP mode and
monitoring of AMP STATUS unless
the amplifier is in any of these
conditions: OFF, SLEEP, or FAULT.
(see Page 29)
Output Connectors
One four-pole touch-proof
terminal strip per channel pair.
Accepts up to 10 AWG wire or
terminal forks.
General Purpose
Input/Output (GPIO)
Connect to the amplifier via
RJ-11. There are 2 analog
input controls and 2 digital
output controls.
BLU Link
Input/Output Ring
Up to 256 channels of digital
audio over Category 5e wiring.
Only 60 nodes should be used
in the BLU-Link Ring.
Ethernet
For monitoring and control of
the amplifier over Category 5e
wiring through the Audio
Architect software.
Power Fuse
F20AH 250V, replace with
same type fuse. LittelFuse 314
Series.
AC Power Inlet
Standard IEC type 320 inlet
for detachable connector
100 - 240 V~
Input Attenuators
One 21-position detented
potentiometer per channel.
Logarithmic audio taper.
Attenuation range mute to
0 dB.
Input Connectors
One 6-pin plug-in connector
per input pair. High
impedance balanced. (Refer
to Page 7).
