2.2.3 Mono 4-way operation
First, activate mono 4-way mode by means of the two MODE buttons on the rear panel. The MONO-LED on

the front panel, above the first LOW CUT button, lights up.

Subsequently, the LEDs above the active controls on the front panel light up, signaling which controls are

active in the operating mode you just selected. The functions of these controls can be seen from the first strip

label.

INPUT control. This control adjusts the input gain from +12 to -12 dB.

2

LOW CUT button. This button activates the 25-Hz high-pass filter protecting the woofers against low-

frequency signals.

LOW/LOW-MID XOVER FREQ. control. This control governs the crossover frequency between the

Low and Low-Mid bands. When the XOVER FREQUENCY button on the rear of the unit is pressed, the

frequency range is multiplied by the factor 10.

4

LOW-MID/HIGH-MID XOVER FREQ. control. This control governs the crossover frequency between

the Low-Mid and High-Mid bands.

DELAY control. This control delays the Low signal by as much as 2 ms, which is useful to align the

speaker systems in phase.
