1.) Power Connection - This is a standard 3-prong IEC power connector
2.) Power Switch - Press the top of this rocker switch inwards to turn on the subwoofer
3.) XLR Inputs - Balanced XLR female connectors are provided for the left and right inputs
4.) Normal/ Invert Switch (Polarity) - This switch reverses the polarity of the signal going into the subwoofer amplifier by 180°
5.) Gain Knob & Sig / Lim LED - The gain knob adjusts the input sensitivity of the mic inputs
6.) High Pass Outputs - Typically , full range loudspeakers are connected to the high pass outputs to "split" the work with the subwoofer.
7.) Full Range Outputs - Connect the full range outputs to the inputs of another powered subwoofer,powered loudspeakers or to an amplifier powering passive loudspeakers.
8.) Stereo / Mono switch (Full range) - This switch allows you to choose whether the A and B inputs are sent out separately (switch out) or as a mono sum of both inputs (switch in)
9.) High Pass Mode - The high pass mode allows you to choose from a list of presets for SRM loudspeakers
10.) Main Logo Switch - The running man logo on the front of the subwoofer illuminates when this switch is disengaged and AC power is available at the mains input.
