INPUT/OUTPUT PROTECTION -
The input circuits are isolated by resistors. An ultrasonic network uncouples RF from the output and helps to keep the
amplifier stable with reactive loads.
OPERATING VOLTAGE (AC MAINS) -
On the rear panel will indicate the correct AC mains voltage. Connecting to the wrong voltage is dangerous and
may damage the amplifier. Always be sure the source voltage for your areas matches the required voltage for your amplifier.
GAIN CONTROLS -
The gain controls are located on the front panel and are calibrated in 2dB of attenuation from full gain. It is best to a d j ust the
amplifier so no “hissing” is heard from speakers with no music being played, this will ensure the lowest possible distortion d u ring normal operation.
AMPLIFIER FEATURES:
THRU (3U Models Only)-
THRU will allow the user to daisy-chain one amplifier’s signal input into another amplifier. Plug the signal source outputs into the
first amplifier’s input, patch from the amplifier’s THRU jacks to the next amplifier’s input, and so on, daisy-chaining as many amplifiers as there is no excessive
level loss.
GROUND LIFT SWITCH (MX-3500 Only) -
Applying or lifting the ground switch will change level for background noise and hum, if the noise level
remains the same in either position, better to keep the ground lift switch in the ground position. This will eliminate 50Hz/60Hz cycle hum that is sometimes
induced when mounting several units in the same rack.
LED INDICATORS -
Each channel has one red LED indicates signal clipping and one green LED indicates input signal is present.
FUNCTION INDICATORS -
These red/green/yellow LED indicators detail the amplifiers current operating mode (Parallel, Stereo, or Bridge).
SUPER BASS PUNCH -
For MX Series 3U Models, you can select to push “ON” to reinforce the bass frequency.
INPUT SENSITIVITY -
The input sensitivity controls will change the volume or output of an amplifier. In the rear panel of the MX series, you can find the
switch to select the desired input sensitivity: 0.775V, 1V or 1.4V. It is set at the factory to 0.775V for rated output into 8 ohms. Before you change the input
sensitivity, please turn off the amplifier and disconnect its power cord from the AC mains power receptacle to avoid danger.
