Mono Channel DSP Amplifier

Description

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 performance out of each subwoofer.

Caution:

MAKE SURE TO READ THIS INSTRUCTION MANUAL BEFORE TURNING THE POWER ON OR HOOKING UP THIS POWER AMPLIFIER.

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. 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.

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.
