TRU-S500DSP
Mono Channel DSP Amplifier
Thank you for purchasing TRU-S500DSP by
TruAudio. The 500 watt DSP amplifier has some
of the most advanced DSP functions available.
We have included DSP settings for all of our
passive subwoofers to get the highest perfor-
mance out of each subwoofer.
Installing Rack Mount Ears
If you are planning on installing this amplifier into a rack,
continue reading how to install the supplied rack ears.
1. Use the supplied three screws to attach the supplied
rack ears to the TRU-S500DSP amp. If required, the feet
on the bottom of the amplifier can also be removed at
this time by unscrewing the mounting screws located in
the center of each foot.
2. Due to the weight of the amplifier, it is recommended
that rear supports be
secured to the rear rack
rails. Hardware to do this
is not supplied with the
amplifier and is specific to
the type and depth of rack
being used.
1. Power Switch: Turns the amplifier on or off. Amplifier
must be on for the trigger or auto sense modes to
operate.
2. 16 Character x 2-row Liquid Crystal Display: Shows
the amplifier’s status, menus and settings and works in
conjunction with the turn and push navigation controls
and the remote control.
3. Programming Navigation Control: Used to scroll
through the display menus, change setting and program
the DSP controller.
4. Optional Rack Ears: Two rack mount ears are
provided for rack mounting.
Back Panel
1. Line Input: For receiving line-level signals. Accepts
either a stereo or LFE signal.
2. XLR Balanced Input: For receiving balanced signals.
Accepts either a stereo or LFE signal
3. 12V Trigger Input: For triggering the power on/off from
other devides such as processors or receivers that have a
12V trigger output. 6V minimum required for triggering.
NOTE: Once in trigger mode, the amplifier cannot be
turned on without a 12V trigger signal. To disable the
12V trigger, press and hold the navigation control knob.
The power switch must be in the ON position. The
trigger mode will be turned off and the amplifier will
power on.
4. Service: For uploading new firmware or updates.
5. IR Input: Link to Infared (IR) hub.
Caution:
MAKE SURE TO READ THIS INSTRUCTION
MANUAL BEFORE TURNING THE POWER ON

6. 5-way Binding Posts: Connect your subwoofer here.
Minimum impedance of the load is 4 ohms. Multiple
subwoofers can be connected if the combined load
impedance is 4 ohms or greater.
7. Voltage Selector Switch: The amplifier can be
used on 110~120V (60Hz) or 220~240V (50Hz) line
voltage. To change the operating line voltage, turn
the power off using the power button and unplug
the power cord. Remove the plastic cover screws
and the plastic cover over the voltage selector
located on the rear of the amp. Set the switch to the
correct position for the line voltage in your country.
Replace the plastic cover and screws over the
voltage selector switch.
NOTE: If required, remove the IEC line cord and
replace with an IEC AC cable that matches the AC
wall socket, this should be a 10A rated cable. When
the voltage selector switch is changed, the fuse
must also be changed to continue to provide
protection to the amplifier.
8. Power Cord Receptacle: The supplied power
cord needs to be connected to this receptacle in
order for the amplifier to work properly.
9. Fuse Holder: This is the power fuse access.
WARNING! In the event the fuse must be replaced,
the replacement fuse must match exactly the
original fuse value or damage to the amplifier may
result. Use a 8A 120V or 4A 240V fuse.
CAUTION! Before replacing the fuse, disconnect
the power cord from the power receptacle.
10. Removable Feet: The amplifier feet can be
removed as required for rack mount installation.
