Check Out behringer.com for Full Manual Proper selection of the two MODE buttons for stereo 2-way operation First, activate stereo 2-way mode by means of the two MODE buttons on the rear panel. The STEREO-LED on the front panel, above the LOW CUT button in channel 2, 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 second strip label. In stereo mode, both channels perform the same functions.
