1. Inputs: The inputs of The BX-4EQ use a balanced input circuit to help minimize induced noise.
It is also designed to handle very high signal voltages up to 15 volts.
2. Outputs: These RCA connectors should be connected to the next component after the BX-4EQ
such as a crossover or amplifier. Just remember, the BX-4EQ should go inline before a crossover.
3. Power Connector
7. Para-Bass Controls: These 2 knobs control the Para-Bass functions of the BX-4EQ. The
SWEEP knob allows you to pick the center frequency that you want the BX-4EQ bass restoration
circuit to maximize. The WIDE knob adjusts how wide of a frequency range the BX-4EQ will effect.
8. The PFM Subsonic Filter Switch: The BX-4EQ utilizes a PFM Subsonic Filter Control which
will help with speaker control and amplifier power management. This PFM Subsonic Filter Control
is variable from 35Hz - 80Hz. On most systems, setting the control at 35Hz is fine. If you want
to protect your speaker system even more, you should try a higher frequency. Often a higher
frequency actually sounds louder and cleaner.
4. Master Volume Control: This is the main control to adjust the output level.
5. Preamp Fader Control: This control adjusts the volume between the front and rear output in
4-channel systems.
6. Subwoofer Volume Control: This adjusts the level of the subwoofer output.
