APX600.5 Power System Amplifier
•Gold-Plated RCA Input Connectors -The Input Connections are Gold- Plated RCA Jacks and are labeled as Right Front, Left Front, Right Rear, Left Rear, Right Sub and Left Sub.
•Gain Controls - The Gain Controls provide a wide adjustment range to accommodate output levels from any brand of source unit. Seperate Front, Rear, and Sub Gain Controls allow you to set the nominal operating level of the amplifier. The amplifier ranges are 250mV to 2.5V for RCA inputs and 500mV to 5V for speaker level inputs.
•Bass Boost Control - The amplifier also features a “high-Q” (i.e. narrow frequency band) Bass Boost circuit for the subwoofer output. It acts much like an equalizer, with an adjustable gain (from 0 to +15dB) 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.
High-pass/Low-pass Filter Controls
•Freq (Hz) Controls - The front crossover frequency is fully adjustable between 55Hz and 5.5KHz (via the front crossover frequency multiplier). The rear crossover frequency is fully adjustable between 55Hz and 5.5 KHz (via the Rear Crossover Frequency Multiplier) for a wide range of crossover points. Use this feature, along with your speaker manufacturer’s specs to adjust to recommended crossover frequencies (see Applications on page 6.) NOTE: If either of the X-Over Mode Switches is set to FULL RANGE, varying the Freq (Hz) Control will produce no effect.
•Front X-Over Frequency Multiplier Switch - When engaged, this switch increases the crossover frequency of the front channels by a factor of 10. Example: If the Freq (Hz) dial is set for 240Hz, pushing in the Multiplier Switch changes the setting to 2400Hz.
•Speaker Level Inputs - These provide connections for a high-level stereo source. In addition, these connections are provided for installations where the source unit’s RCA outputs are unavailable such as OEM radios.
WARNING: When using the speaker (high-level) inputs, the Black wire must be grounded at the Radio. Failure to do this will result in noise and improper operation.
