MTX Audio TA3404 specifications Troub le Shooting, Problem Cause

•Setting For Components and Separates: First enable the electronic crossover by selecting the “ON” position of the X-OVER switch, then select the “H-PASS” (High pass) position on the L-PASS/H-PASS switch.

By selecting this you are giving the speakers 85Hz – 20kHz. The 12dB/Oct roll off means that the frequencies under (lower then) the set 85Hz, will taper off at moderate slope.

•Setting For Full Range (No Crossover): To disable the electronic crossover, select the “OFF” position of the X-OVER switch. This setting will allow the amplifier to play all frequencies.

4.Remote Subwoofer Level Control (Remote Sub) – Lets say the amplifiers gain is set at half way, when the remote subwoofer level control is plugged in, you now have external control of the gain from zero – half way. The installation of this level control is NOT necessary to get full power from amplifier.

5.Prizm EFX – Now that you have completed adjusting all your amplifier settings, you can set the lighting effects to you personal taste.

•Selecting Colors: You can change the backlit colors simply by turning the Pot labeled PRIZM COLOR located in the MTX PRIZM EFX section of the control panel left or right. Starting at the most counter clockwise position, the colors range from RED, GREEN, BLUE, and RED again or any color in between making the combination unlimited.

•Selecting The EFX Feature: You can switch Prizm EFX lighting to “pulsate” with beat of music. Simply depress the button labeled PRIZM EFX located in the in the MTX PRIZM EFX section of the control panel to turn this feature on or off.
