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.

  If you're not getting any sound from your subwoofer, there are a few things you can check: * First, ensure that the amplifier is properly plugged into a functioning A/C power outlet and that it's receiving power. * Second, verify that the subwoofer is correctly connected to the amplifier. * Finally, confirm that the pre-amp or receiver is sending an audio signal to the amplifier.

  If some subwoofers are working, but others aren't, try these steps: 1. Make sure all wires are properly connected. 2. Check that all connections are complete and secure, and that there are no stray wires touching other terminals. 3. Check each individual subwoofer.
