•Gain Control - This allows you to set the nominal operating level of the amplifier. The amplifier’s range, 250mV to 2.5V for RCA inputs, can accommodate input levels from virtually any brand of source unit.

•Bass Boost Control- The amplifier also features a “high-Q” (i.e. narrow frequency band) Bass Boost circuit. It acts much like an equlaizer, with adjustable gain (from 0 to +18dB) fixed at 45Hz. Use this feature to tune low- frequency audio response to compensate for a less than ideal subwoofer enclosure design. The added boost produces rich, full bass tones that are normally difficult to reproduce in the car audio environment. NOTE: If Bass Boost is undesired, set Bass Boost to 0dB.

•Pass Through - This allows you to “daisy chain” multiple amplifiers by internally splitting off the RCAinput to the Pass Through output. (The Pass Through output signal will be identical to the input signal. For example, full range in equals full range out, 50Hz low-pass in equals 50Hz low-pass out.)

•Power Save - When engaged, the amplifier will automatically minimize the current drawn while the amplifier is idle or the system volume is at a low level. This feature increases your amplifier’s efficiency by not drawing unnecessary current.

High-pass/Low-pass Filter Controls

•Frequency (Hz) Selection Control - The crossover frequency is fully adjustable between 50Hz and 5500Hz (via the Crossover Frequency Multiplier) for a wide range of crossover points. Use this feature, along with your speaker manufacturer’s recommended crossover frequencies, to quickly design a more advanced system (see Applications on page 5.) NOTE: If the X-Over Mode Switch is set to FULL, varying the Freq (Hz) Control will produce no effect.

•Crossover Frequency Multiplier Switch - When engaged, this switch increases the crossover frequency by a factor of 10. Example: If the Freq (Hz) dial is set for 240 Hz, pushing in the multiplier Switch changes the setting to 2400 Hz.

•X-Over Mode Switch - This switch is equipped with a selectable 12 or 24dB per octave electronic filter for precise frequency attenuation with minimal phase distortion. The steep crossover slope keeps midrange tones out of the subwoofer and thereby eliminates an unnatural “nasal” tone quality in the audio system. A filter is activated by sliding the X-Over Mode Switch to either LP or HP.

•Input Mode Switch - This switch allows you to set the input mode. Stereo input allows full left and right stereo operation. Right (bridged) input allows single channel input for bridged operation. This is especially useful in high- powered systems when using one amplifier for each subwoofer/speaker. L + R (sum mono) allows a stereo input to be summed into a mono output.
