Max-X2 FRONT PANEL

CONTROLS

1. LOW GAIN CONTROLS:

These are used to adjust the LOW GAIN level of each channel.

2. LOW CUT SWITCHES:

These insert low cut lters in the LOW GAIN of each stereo channel with a 12dB/Octave, 30Hz HPF to mini-

mize problems from subsonic frequencies in the signal, to suppress hum and to prevent low frequency speaker

resonance.

3. XOVER FREQ (crossover frequency controls):

These select the crossover frequencies for the LOW and HIGH outputs. They are a low cut for the HIGH and a

high cut for the LOW. You can select the frequencies between 250 Hz and 6 KHz.

4. HIGH GAIN controls:

These are used to adjust the HIGH output level.

5. PHASE switches:

These allow switching the polarity to invert the signal phase on the HIGH outputs. This is done after the output

levels are set to correct audible phase problems.

Caution: Before pressing the PHASE switches, always lower the outputs of

your power ampliers to avoid possible speaker damage.

6. BBE PROCESS controls

When the knob is in its minimum position, completely counterclockwise, no process is taking effect and the

circuit is in its noise suppression mode. Turning the knob clockwise will introduce the BBE Process. Adjust the

knob to mix the desired amount of process to suit your taste. Generally a good place to start the BBE process

is to set the knob to it’s 12 o’clock position, then adjust accordingly.

7. BBE LO CONTOUR controls

This control is a low frequency adjustment for the BBE Process. It provides a boost of 12dBu when turned to

its maximum position (clockwise) at 50Hz. When turned to its minimum position (counter-clockwise) it would be

at or no change.

8. BBE ON/OFF SWITCH

This switch engages the BBE Process as indicated by the green LED. When in the “OUT” position, the green

LED will not illuminate, indicating that the BBE Process has been disengaged.

9. POWER SWITCH

Caution: Always turn the Crossover ON before the amplier, and turn it OFF after the amplier or transients

harmful to the speakers may result.
