A feature found only with PinWoofer – externalized Service Menu Buttons! This allows access to and adjustment of anything in the service menu without opening the coin door. (There is a concealed disable switch found on the back of the Coin Door Module if you would like to temporarily or permanently disable the external service menu buttons.)

Features an integrated PinWoofer BBU (Bass Boost Unit) that allows for boost of the signal sent to your externally powered subwoofer. The result is an improvement in bass signal and bass quality. The BBU roll-off is quite steep (~35dB / decade above ωc) so the result is filtering of unwanted high bass that might otherwise rob power from the bass spectrum and reduce quality. It is not surprising that the result is a "purification" so to speak, of the bass signal provided to the external and less energy is wasted on high bass.

Maximum boost ~8dB (~2.5x).

Cutoff frequency is adjustable ~50-173Hz @ -3dB ωc.

Frequency roll-off ~35dB/Decade.
