High and Low Level Inputs
An amplifier with both high-level and low-level inputs provides flexibility by allowing you to build an audio system using virtually any standard factory or aftermarket source unit. High-level (speaker level) inputs accept the signal from the speakers, while low-level (RCA) inputs accept the signal from the pre-amp outputs of the source unit.
The phase control feature allows you to adjust the speakers phase to ensure all audio signals are playing together rather than against each other. When bass notes are noticeably absent, a quick and easy adjustment to the phase control could provide the perfect remedy.
If the amplifier gets too hot, the thermal protection circuit turns the amp off and allows the amp to cool down before turning it back on. If a speaker fails causing an electrical short, the protection circuit will automatically cut the output and remain in that state until the short is resolved. These safety features give you peace of mind knowing the amplifier is constantly monitoring conditions to protect itself.
Single Voice Coil
A subwoofer with a single voice coil can be powered by an appropriately matched amplifier or can be combined with multiple single voice coil subwoofers to achieve a variety of impedances to match your amp set up. Single voice coil subwoofers are generally ideal for low to medium-power applications.
A subsonic filter is designed for use on subwoofers. Since not all subwoofers can reproduce the same low frequencies, the subsonic filter can be set for optimum bass response in order to keep the driver playing efficiently.
Subwoofer Level Control
The ability to boost or attenuate the sub level when an amp and subwoofer are connected to the subwoofer pre-amp output.
Variable Bass Boost
Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.
Variable Gain Control
Variable Gain Control lets you balance the amps output with the speakers or subs the amp is driving. To much gain will lead to distortion and to little will lead to clipping.
Variable Low Pass Filter
Variable low-pass filter gives you control over the frequencies that pass through to the subwoofer.
