PowerBass XL specifications Xaamplifiers, Class Amplifiers

A/B Class Amplifiers

If you’re looking for raw power, then look no further. PowerBass’ mission has been to develop and refine audio products that satisfy the most demanding enthusiasts. The XA PowerBass amplifiers deliver pure, clean power.

The XA amplifier starts with a low profile, high density extruded aluminum heatsink for maximum heat dissipation. We then add custom tooled brass terminal speaker and power terminal blocks for excellent conductivity, and then offer low level inputs AND outputs that send a full range signal on to additional amplifiers for easy system design.

Inside the amplifiers, we use a PWM (Pulse Width Modulated) switching power supply and MOSFET transistors for increased output voltage. To make sure that the proper signal gets to your speakers, we have an adjustable 12 dB/octave high pass crossover with a range 50

–250Hz and a low pass crossover with a range of 40 – 400 Hz to allow for multiple applications. To get that low bass bump, we equip the XA amplifiers with an EQ with 18dB of boost at 45 Hz. As you will find out, the XA amp will provide your PowerBass speakers with plenty of clean power.

FULL RANGE A/B AMPLIFIERS

Low Profile Finned Heatsink High density extruded aluminum heatsink for maximum heat dissipation and bulletproof reliability.

PWM MOSFET Power Supply PWM (Pulse Width Modulated) switching Power Supply combined with MOSFET transistors for increased output voltage.

Variable Electronic Crossover Overlapping LPF (Low Pass Filter) variable from 40Hz~500Hz and HPF (High Pass Filter) variable from 20Hz~1.5KHz. Plus Built-in Bass EQ @ 45Hz.

Custom Tooled Speaker And Power Inputs Solid brass tooled terminal blocks with Nickel finish to ensure a quality electronic connection alowing maximum signal transfer.

Low Level Inputs And Outputs Balanced RCA style connections allow you to daisy chain amplifiers together for multiple hookups.

The D Class range of XA amplifiers are designed to run subwoofers with less power demand on your vehicle’s electrical system. The XA amplifiers come fully equipped with features to run your subwoofers no matter what size or the type of music you listen to. First a 24-dB/octave crossover to cut the high frequencies out of your subs and concentrate all of the amplifiers into the subwoofers intended frequency range. In addition to cutting high frequencies, we also include a subsonic filter to cut frequencies too low to be heard and waste amplifier power. The included remote bass control allows control of the volume of the subwoofers when you need to increase the output of the subwoofers. For SPL applications, the XA amplifiers can be strapped together for serious power to individual voice coils - or just because.

D CLASS AMPLIFIERS

Remote Bass Control (Included) Wired dash mounted remote allows you to fine tune the amp's special BASS EQ circuitry. Variable from 0~18dB.

Strap Two Amps Together For Double Power Output Allows two of the same model amplifier to be combined in a Master/Slave configuration to function as one for increased power.

Oversized Power And Ground Inputs Heavy duty 1/0-Guage CNC machined high efficiency Power and Ground Inputs for maximum power transfer.

24 dB/Octave Electronic Crossover Variable LPF (Low Pass Frequency) from 20Hz~1.5KHz plus a separate variable SubSonic filter for maximum system flexibilty.

Self-diagnostic Protection Circuitry 4-way protection circuitry guards against Short Circuit/Thermal Overheating/Impedance Overload and DC Output.
