5.1 Level Control
The large knob labeled ТҮВШИН adjusts the output volume of the stereo signal. Rotate clockwise to increase the level and counter-clockwise to decrease it. Start with the level at minimum and gradually increase it to achieve the desired output volume without clipping at your mixer.
5.2 Mono Fold-Down Switch
The button labeled МОНО, when engaged, sums the left and right stereo input signals into a single mono output. This is useful when feeding a mono sound system or when you need to check for phase issues in a stereo mix. When disengaged, the unit operates in stereo.
5.3 Газрын өргөгч унтраалга
The button labeled Өргөх activates the ground-lift function. This switch disconnects the audio ground from the chassis ground, which can help eliminate hum and buzz caused by ground loops between the source device and the connected audio system. If you experience hum, try engaging this switch. If the hum persists, ensure all equipment is properly grounded and check cable connections.
