3.1 CONTROL PANEL - AS 101S LEVEL CH1/CH2 (1) - High-pass output level control, which determines the amount of signal sent to the satellites. Turn the knob completely clockwise for unitary gain. PHASE (2) - Phase inversion 0°- 180°. In some installations, the subwoofer may be out of phase with the satellites. This switch allows you to reverse the phase of the subwoofer and align the system. CLIP (3) - Clip indicator LED. This indicator allows you to visually monitor the volume level of the loudspeaker.
signal from the electrical ground of the power amp module. This switch may be needed for the cancellation of hum due to ground loops with other apparatuses. If the audio signal is already disturbed when it arrives to the loudspeaker, this switch will not solve the problem. Identify the upstream component that is creating the problem, and take whatever measures are necessary to eliminate the hum.
LEVEL SUB (12) - This control determines the amount of signal that passes through the input stage of the subwoofer. Turning it completely clockwise will result in maximum gain. The appropriate subwoofer level can vary significantly depending on the acoustics of the venue and the genre of music you’re playing. Carefully set the satellites’ level first and then add bass frequencies (subwoofer level) as needed. CLIP (13) - Clip indicator LED.
