Features
1. Prizm EFX – All MTX amplifi ers 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 fi ns. Fan speed is continuously variable and controlled
by the amplifi er’s output, temperature of the 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 amplifi ers feature RCA type input connections. All MTX
amplifi ers allow both high level and line level input into the 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 amplifi ers 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-on circuit is included within the amplifi er. A remote turn-on
wire is not necessary when connecting the amplifi er’s high-level input to a high-powered source unit (car
stereo). The amplifi er will automatically turn on when music is received through this type of connection.
Note: Smart Engage™ is only active on the left input.
