Functions

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.
