Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Controls

Gain: The rotary gain control is continuously variable from 125 mV to 5 V when the Input Sensitivity switch is set to Low and 250 mV to 10 V when the Input Sensitivity switch is set to High.

Crossover: The crossover is always engaged (cannot be bypassed). The crossover point is continuously variable from 50 to 200 Hz and the slope is 24dB per octave.

Auto Turn-on Switch: The amp offers three automatic turn-on modes; select from:

• +12V: connect a wire from the remote turn-on lead from your source unit to the REM terminal on the amplifier; this is the preferred turn-on method
• DC Offset: turns the amp on when a 6-volt DC offset is detected at the high-level speaker inputs when the source unit is turned on
• Audio: detects the incoming audio signal from your source unit and automatically turns the amp on; will not work if the input gain control is not set properly

Bass Boost: The bass boost circuit provides up to 18dB boost at 40Hz.

ZXRC Remote Bass Control: The bass output level can be controlled remotely using an optional wired remote bass control (item number 20610ZXRC, sold separately).
