XMA-4250IR XMA-5900IR XMA MINI FRD AMPLIFIER Owners Manual Please read through this manual to familiarize yourself with your new amplifi er. Should your PowerBass Xtreme mobile amplifi er ever require service, you will need to have the original dated receipt.

In the interest of safety, PowerBass USA highly recommends listening at lower volume levels when driving.
This amplifier represents the very latest in Class D technology. The XMA Series uses the new IR® (International Rectifier) platform which has been under development for the past several years. IR®, a leader in PWM circuit design, has worked in conjunction with PowerBass engineers to produce more stable power output, minimal RF interference and improved sound quality.
• Electronic (Rosen not Acid Core) Solder INSTALLATION PRECAUTIONS NOTE: Proceed only if you are a qualified installer, otherwise; see your Authorized PowerBass Dealer to professionally install this amplifier. Always wear protective eyewear when using tools. • Turn off all stereo and other electrical devices before you begin.
Fan (XMA-5900IR only) Fig.1 Mounting Amplifier To keep your PowerBass Xtreme amplifier running at top performance, choosing the proper location is of utmost importance. Both Thermal and Overload protection are built in. In the event of overheating, the amplifier may temporarily shut down operation. For this reason the amplifier should be mounted in a loca- tion which will allow air to circulate freely.
FUSE REQUIREMENTS While the panel your PowerBass amplifier incorporates one or more fuses, these do nothing to protect the vehicle from a dangerous short circuit. It is absolutely vital that the main power lead to the amplifier(s) in the system be fused within 18-inches (45cm) of the connection to the vehicle battery. The value of this fuse (or circuit breaker) should be no greater than the sum of the fuses found on all of the equipment being connected to that power wire.

Line INPUT (RCA) Jacks These RCA style input jacks are for use with source units that have RCA line level outputs. A source unit with a minimum of 250mV is required for proper operation.

12. REM (Remote Input Connection) All PowerBass Xtreme amplifiers can be turned on by applying 12 volts to this terminal. This can be found on the rear of the source unit in the form of a remote output. If this is not available you can wire to the ACC position on the key.

Remember, bigger wire is better! For best results we recommend a PowerBass ampli- fier install kit, available at your local PowerBass dealer.
These amplifiers are designed to work within a 10 to 16 volt DC range. Before any wires are connected, the vehicles electrical system should be checked for correct voltage supply with the help of a voltmeter. First, check the voltage at the battery with the ignition in the OFF position. The voltmeter should read no less than 12V.

Now it’s time to connect the power and ground cables to the amplifier. Cut both cables to length. Strip off 1/2 inch (12mm) of the insulation so that the bare wire fits all the way in the terminal block on the side panel of the amplifier, seating it firmly so no bare wire is exposed.

RCA INTERCONNECT (XMA-2200IR/2405IR) Fig.5 Low Level Input using RCA Low Level Input - Choose the correct length and style of RCA interconnects for your needs. Always use high quality RCA audio cables (not supplied) for signal connections—those with multiple layers of shielding or a twisted pair variety for better noise rejection.

XMA-5900IR (continued) Three RCA OUT (Front and Rear plus Subwoofer) Fig.7c Three RCA Outputs from the Radio (Front and Rear plus Subwoofer) This is the optimum configuration for this amplifier by providing 3-sets of discrete signal to the preamp. It will also offer the most flexibility in tuning the system.

SET UP ADJUSTMENTS INPUT Gain Adjustment GAIN Fig.9 GAIN Control This control allows you to match the input level of the amplifier to the output level of your head unit. Matching the input can be accomplished in three simple steps: Set the volume of GAIN on the amplifier to Min (completely counter clock wise).

25Hz 250Hz Fig.12 Low Pass Control (LPF) LPF (Low Pass Filter) 40 Click Detent Control Using this volume, adjust the LPF frequency for your subwoofer speaker(s) operation. The X-OVER switch position should be at “LPF”. Use the enclosed chart to precisely dial in desired frequency. See the charts on pages 24-27 to set the Low Pass Filter to the precise frequency for your particular amplifier.
SPEAKER WIRING AND CONFIGURATIONS Speaker Load Keep in mind your PowerBass Xtreme amplifier is a high power amplifier and not a high current amplifier. In other words this amplifier requires a minimum impedance of 2 ohms STEREO or 4 ohms bridged MONO to operate trouble free.

40 CLICK PRECISION ROTARY CONTROLS These controls allow precise setting of the electronic crossover settings on the amplifier, thus taking the guesswork out of tuning your speakers. Using a small slotted screwdriver make sure the controls are turned all the way to the left (counter clockwise). Refer to the chart and count the clicks (advancing one detent at a time clockwise) until you have reached the desired frequency.

NOTE: If the Status L.E.D. is activated and glows RED with no speakers connected to the amplifier, and all the power connections are correct, this would indicate an internal problem with the amplifier. Contact PowerBass USA or your local dealer.
