•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 or 500mV to 5V for speaker level inputs, can accommodate input levels from virtually any brand of source unit.
•Bass Boost Control- The amplifier also features a
High-pass/Low-pass Filter Controls
•Frequency (Hz) Selection Control - The crossover frequency is fully adjustable between 55Hz 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
•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.
•
•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.
•Speaker Level Inputs - These provide connections for a
