Features
1. Prizm EFX – All MTX amplifiers include backlit adjustment controls on top surface of product.
• Color – The backlit controls offer unlimited colors on the display -- from RED, GREEN, BLUE, or any color
in between.
• EFX – You can switch Prizm EFX lighting to “pulsate” with beat of music.
2. Xtant Technology Cooling (XTC) – thermal-regulated turbo-charged inner cooler, supplies fan forced cool
air evenly and constantly through tightly packed, bonded fins. Fan speed is continuously variable and
controlled by amplifier’s output load, temperature of heatsink and transformers. Exhaust of internal heatsink is
strategically positioned to cool transformers to maintain maximum performance at all volumes.
3. Bi-Level Inputs with Smart Engage – All MTX amplifiers feature RCA type input connections. All MTX
amplifiers allow both high level and line level input into the RCA type input connections.
• Low Level Input – All MTX amplifiers feature RCA type input connections. 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: is an auto turn-on circuit included within the amplifier. A remote turn-on
wire is not necessary when connecting the amplifiers 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.
Note: Smart engage is only active on the left input.
