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 LOW CUT button in channel 1, 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.

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

(2)LOW CUT button. This button activates the 25 Hz highpass filter protecting the woofers against low-frequency signals.

(3)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.

(5)DELAY control. This control delays the Low signal by as much as 2 ms, which is useful to align the speaker systems in phase.

(6)LOW OUTPUT control. Controls the output level of the Low band from +6 to -6 dB.

(7)LOW PHASE INVERT button. This button reverses the polarity of the Low output.

(8)LOW MUTE button. Mutes the Low band.

(9)LOW-MID OUTPUT control. Controls the output level of the Low-Mid band from +6 to -6 dB.

(10)LOW-MID PHASE INVERT button. This button reverses the polarity of the Low-Mid output.

(11)LOW-MID MUTE button. Mutes the Low-Mid band.

(15)CD HORN button. This button provides a special form of frequency correction in the High band for constant-directivity horns.

(19)HIGH-MID/HIGH XOVER FREQ. control. This control governs the crossover frequency between the High-Mid and High bands.

(24)HIGH-MID OUTPUT control. Controls the output level of the High-Mid band from +6 to -6 dB.

(25)HIGH-MID PHASE INVERT button. This button reverses the polarity of the High-Mid output.

(26)HIGH-MID MUTE button. Mutes the High-Mid band.

(27)HIGH OUTPUT control. Controls the output level of the High band from +6 to -6 dB.

(28)HIGH PHASE INVERT button. This button reverses the polarity of the High output.

(29)HIGH MUTE button. Mutes the High band.

(30)THRESHOLD control. This control determines the limiter threshold.

(31)LIMITER button. This button activates all limiters. Whenever the signal surpasses the limiter threshold, the LIM-LEDs above the Gain control light up, signaling that the CX3400 cuts back the output level.
