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 level, temperature of the heatsink and transformers. Exhaust from the internal heatsink is strategically positioned to cool the transformers and 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.

4. Input Sensitivity – The Input Sensitivity switch 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)

5.Individual Gain Control – This feature is used to fi ne-tune the input sensitivity of the amplifi er to the source unit’s output level.

6.Variable Hi, 12dB / Low, 24dB Mono 40Hz–350Hz X-over – This control allows the user to choose the exact low pass or high pass frequency range the amplifi er will play for the best possible performance. The upper end of the low pass crossover range can be selected from 40Hz–350Hz at 24dB per octave with a mono output. The lower end of the high pass crossover range can be selected from 40Hz-350Hz at 12dB per octave with a stereo output.

7.Fixed Subsonic Filter – This feature limits frequencies from 30Hz at 12dB per octave and below to be sent to the subwoofers. The subsonic feature includes a selectable on/off switch and a control knob used to adjust.

8.Parametric Equalizer – This one band parametric equalizer provides individual frequency, Q/bandwidth, and -/+ 12dB gain adjustment controls. Any frequency from 30Hz to 80Hz can be chosen and boosted 12dB. The “Q” ranges from 0.5 to 4.0 in value allowing a wide variety of bandwidth adjustment to address the subtle tuning requirements common to mobile audio systems.

9.A.R.C. – The Active Resonance Control (A.R.C.) is a level adjustment that reduces the resonant frequencies inside the vehicle to improve the midrange sound quality. Turn this control either clockwise or counter clockwise until the vocals of the music are up-front and centered in the vehicle. The midrange sound should be smooth and detailed.

10.Remote Subwoofer Level Control (Remote Gain) – This port allows the use of the optional “remote level control”. The Remote Subwoofer Level Control is a bass control module that can be installed in any location within the vehicle for remote adjustments.

11.Processor Bypass – This feature routes the audio signal around all enhancement features to achieve a purely fl at response.

12.StreetWires Connectors – All MTX amplifi ers include StreetWires connectors for effi cient current and maximum voltage transfer.

13.Speaker Connection – These output terminals are individually labeled for proper speaker connections. When bridging the amplifi er, use the left positive terminal and the right negative terminal only. Warning, do not bridge the amplifi er with an impedance lower than 2 ohms (this amplifi er is 1 ohm stable / 2 ohm bridgeable).

14.Power Terminals – This is the main power connection for the amplifi er. The power and ground wire size should be the same gauge.

• GND: The ground wire from this connection must be attached to bare metal on the vehicle. The distance to the ground should be as short as possible and no more than 18”.

• REM: To turn the amplifi er on/off, this terminal must be connected to the source unit’s “remote or electric antenna” wire.

• +12V: The power wire from this connection must be attached to the positive side of the vehicle battery.

• CAP+: Capacitor Positive Input - The ideal connection point for the positive sides of the capacitor to increase the amplifi er’s performance.

• CAP-: Capacitor Negative Input - The ideal connection point for the negative side of the capacitor to increase the amplifi er’s performance.
