1. POWER SWITCH (reset)
Push the upper portion of the power switch to turn the system on. If the
blue POWER indicator is on but there is no sound or if the Protect LED
is on, check for; a) lack of INPUT signal, b) too many speakers attached
to the SATELLITE SPEAKER output, c) bad speaker cable, d) damaged
external speaker, or e) blocked fan intake. If the problem persists, reset
by turning the power off for 10 seconds and then turn it back on.
2. POWER LED
The POWER LED indicates the unit is turned on and functioning properly.
3. SIGNAL LED
The SIGNAL LED indicates there is a signal present at the INPUT XLR.
4. LIMIT LED
The LIMIT LED indicates maximum output of the system is being reached.
A flashing LIMIT LED is acceptable, the DSP will reduce peaks to prevent
amp clipping. If the LIMIT LED is continuously ON, reduce the level
going in to the INPUT XLR. You can also adjust the DSP setting for Input
Sensitivity. As with any system, reduce the volume if distortion is heard.
5. DIGITAL DISPLAY
The bright green LED DIGITAL DISPLAY will display various information
about the system and its settings. When you first turn on the unit, the
display will indicate which preset is loaded. To change settings use the
UP/DOWN
pq
(SET) and LEFT/RIGHT
t
u
buttons.
6. SETTING BUTTONS:
t
u
pq
(SET)
Use the UP and DOWN (SET) buttons to select “the TRx3903 External”
preset. The LEFT and RIGHT buttons will allow editing of more advanced
settings, which are explained in the DSP SETTINGS section of this manual.
There are only a few settings to select from.
7. INPUT/THRU XLR CONNECTORS
Connect the INPUT XLR to a signal source such as the output of a mixer.
The THRU XLR can be connected to more TRx3018A’s or other units.
8. REMOTE LEVEL (MUTE) CONNECTOR
This is a terminal block connector with 5 volt control of volume, typically
used in permanent installations. Short the CTL and GND pins to MUTE.
9. USB PORT
The USB port is for updating system firmware such as additional presets
for Carvin Audio speakers including the SATELLITE SPEAKER output.
10. PROTECT LED
The PROTECT LED indicates one of the protection circuits has activated
and no sound will be heard from the amp. To reset the amp, turn the
power off for about 10 seconds, then turn it back ON. If the PROTECT
LED stays lit for more than 5 seconds, check your SATELLITE SPEAKER
cable connnections, speaker impedance or a blocked fan intake.
11. SATELLITE SPEAKER OUTPUT
The SATELLITE SPEAKER output is a Twist-Lock connector for power-
ing external speakers. Presets for several Carvin Audio speakers are pre-
programmed. For TRC-A systems, choose the “TRX3903 External” preset
on the display. Manual settings are available for other speakers. Speakers
can be chained together so long as the total impedance does not go below
4 ohms (two TRx3903’s). If you go below the minimum speaker load, the
amp may shut off or the red PROTECT LED may light. To reset the protection
circuit, turn off the POWER switch and connect the recommended load.
12. FAN INTAKE / EXHAUST VENTS
The TRx3010A/TRx3018A power module features a variable speed fan,
which runs silent at low speeds. Make sure the fan intake and exhaust
vents are free from blockage at all times.
13. AC IN / AC OUT POWER JACKS & FUSE
Be sure to plug into the proper voltage using AC IN jack. A detachable
locking power cord is supplied (for European 230V use a CEE-7 plug cord
set). Plug the cord into a grounded 3 prong power source. No attempt
should ever be made to use the amp without the ground connected.
The AC OUT connector can be used to power one TRx/3010A/TRx3018A,
a powered speaker, or any device(s) with a total of 10A rating or less.
The FUSE is located internally near the AC input. To check or replace,
first remove the power cord and then remove the amp module from the
speaker enclosure and remove the front panel to access the fuse. The
fuse type is a 250V Slow Blow rated at 15A.
A locking AC cord (Carvin part# 120V16L7, 120V model) is supplied
with the amp. However, a standard AC cord can be used. To detach the
cord from the amp, press the release lever on the underside of the cord
near the amp.
