CONTROLÊPANELÊFEATURES
1. POWER SWITCH (reset)
Push the left portion of the power switch to turn the system on. If the
blue POWER indicator is on but there is no sound or the Protect LED is
on, reset, turn the power off for 10 seconds and then turn it back on. If
the problem persists, check for no input signal or a blocked fan intake.
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 that the maximum output of the system
is being reached. A flashing LIMIT LED is acceptable, the DSP will
reduce peaks to prevent amp clipping. However, if the LIMIT LED is
continuously ON, reduce the level going in to the INPUT XLR. As with
any system, reduce the volume if distortion is heard.
5. DIGITAL DISPLAY
The bright green LED DIGITAL DISPLAY will display various infor-
mation about the system and its settings. To change settings use the
UP/DOWN (SET) and LEFT/RIGHT buttons.
6. SETTING BUTTONS (SET)
Use the UP and DOWN (SET) buttons to load different presets for
speaker configurations or to increase or decrease settings. The LEFT
and RIGHT buttons will allow selection of the different settings.
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 TRx3810A VELA
cabinets, powered subwoofers or other units.
8. REMOTE LEVEL (MUTE) CONNECTOR
This is a terminal block connector with 5 volt control of volume, typi-
cally 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 new presets.
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 for a
blocked fan intake.
11. FAN INTAKE / EXHAUST VENTS
The 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.
12. AC IN / AC OUT POWER JACKS
The AC IN / AC OUT use the Neutrik™ PowerCon™ A-Type and
PowerCon™ B-Type connectors.
AC IN accepts Neutrik™ # NAC3FCA.
AC OUT accepts Neutrik™ # NAC3FCB.
A detachable power cord kit is supplied to
connect the AC IN to a standard wall outlet.
The AC OUT connector can be used with a NAC3FCA to NAC3FCB
cable to power other units such as another TRx3810A, or up to two
devices with a total rating of 15A or less. Other limiting factors include
the breaker rating for the AC line you are plugging into, wire type and
(if used) generator capacity. No attempt should be made to use the
amp without the ground connected.
13. FUSE
The FUSE is located internally near the AC input. To check or replace,
first remove the power cord. Then remove the amp module from the
speaker enclosure and remove the front panel to access the fuse.
The fuse # is a 250V Slow Blow rated at 10A.
