1. Input - Two balanced 1/4"/XLR combo jack are provided. This allows for stereo input from two
separate feeds. The subwoofer will work with only one input connected.
2. Output - Two full-range passthrough XLR outputs are provided. These outputs are not affected by
the LPF and will send a full-range signal on the rest of your PA setup.
3. Subwoofer Volume Control - This controls the gain of the input signal. It will raise and lower the
volume of the subwoofer. Standard usage is setting this control at 50%.
4. LPF Control - Low Pass Filter, this controls how much high frequency is filtered out of the signal
and how much of the higher bass frequencies are left in the signal. This does not add bass to the
signal, it determines how much high frequency is cut out of the signal. Setting this control to the
middle usually works best.
5. Clip LED indicator lights up when the amplifier is near clipping. An occasional flickering is accep-
table. If LED is lit continuously adjust the Level control and reduce the output level of connected
sources. Failure to do so may lead to premature failure of your speaker.
6. Power LED will light when the subwoofer is turned on.
7. Polarity switch button reverses polarity of subwoofer and is dependent on the placement of the
subwoofer relative to the speakers.
8. Satellite Volume Control - This controls the gain of the output signal to the satellite speakes.
9. Balance - This controls the pan of the sound in the stereo mix. It enables you to bias the output
towards one side or another, if needed.
10. 200Hz High Pass Filter - On/Off switch to remove low frequencies from the satellite speaker output.
11. Power Output - Two Speakon connectors for powering satellite speakers. They will deliver 150W
RMS at 8 ohms. Not recommended for 2 or 4 ohms loads.
12. Power Output - Two binding post connectors for powering satellite speakers. You can use either
Speakon or Binding post for powering out but don't use both at the same time.
13. Power Switch
14. Voltage selection-This switch is supplied for moving the unit from 115 voltage (US Standard) to
230 voltage (European Standard). The switch needs to be set on the proper voltage for your area.
15. IEC input - This receptacle is for connecting the included IEC power cable. It is important to
supply the proper AC line voltage to the unit. Do not connect to intermittent or faulty power.
