Features

1. Prizm EFX – All MTX amplifiers include backlit adjustment controls on the top surface of the product.

•Color – The backlit controls offer unlimited colors on the display -- from RED, GREEN, and BLUE to any color in between.

•EFX – You can switch Prizm EFX lighting to “pulsate” with the beat of the music.

2.Xtant Technology Cooling (XTC) – A thermal-regulated turbo-charged intercooler supplies fan forced cool air evenly and constantly through tightly packed bonded fins. Fan speed is continuously varying and controlled by the amplifier’s output, temperature of heatsink, and transformers. Exhaust from the internal heatsink is strategically positioned to cool the transformers to maintain maximum performance at all volumes.

3.Bi-Level Inputs with Smart Engage™ – All MTX amplifiers feature RCA type input connections.

•Low Level Input – Source units with an output signal level of 100mV–10V may be used. See “Input Sensitivity” for proper voltage level setting.

•High Level Inputs with Smart Engage™ – All MTX amplifiers allow high level inputs through RCA type

input connections using provided high level adapters. Source units with an output signal level of 100mV–10V may be used. See “Input Sensitivity” for proper voltage level setting.

•Smart-Engage™ Auto-Turn-On - An auto-turn circuit is included within the amplifier. A remote turn-on wire is not necessary when connecting the amplifier’s high-level input to a high-powered source unit (car stereo). The amplifier will automatically turn on when music is received through this type of connection.

4.Input Sensitivity – The Input Sensitivity is used to set the proper input voltage range:

X1 POSITION: 100mV–1V (Typically for RCA Input)

X10 POSITION: 1V–10V (Typically for Speaker Level Input)
