established using 1/4 inch TRS or XLR connectors.
Volume control for adjusting the individual inputs' level. The 12 o'clock
4
position is unity gain (no gain or attenuation), the range to the left of
5
6
zero(0) is for adjusting line level sources, and the range to the right of
3
zero(0) is for adjusting microphone levels. LINE and mic input level
7
control is available for both INPUT 1 and INPUT 2.
2. AUX/BT Input
A CD, IPhone and Bluetooth signal for AUX/BT in or Input 2 channel

or subwoofer. INPUT LEVEL controls the signal level to OUTPUT. The
MASTER VOL or DSP control setting do not affect OUTPUT.
4.LIMIT(Automatioc amplitude limiter):
Automatic amplitude "LIMIT" LED; when the audio signal reaches the
dangerous threshold for the transducers, this circuit will automatically
intervenes by reducing the amount of signal in order to protect the
speaker, avoide losing roue and despicking distortion as well; the
