The PRIME R250-1 amplifier is a great mono amplifier in a compact chassis and respectable power output making it perfect for a center channel speaker in a 5.1 surround sound system. The R250-1 mono output design also makes it great for running a pair of 8″ or 10″ 4-ohm SVC subwoofers wired in parallel. The included Remote Punch Level Control corrects for any acoustic anomalies in the automobile environment, making certain that bass notes sound deep and rich.
R250-1 Key Features
Power and Protect LEDs
The Protect LED illuminates if a short circuit or to low of an impedance is detected at the speaker connections. The amplifier will automatically shut down if this occurs.
RCA Input Jacks
The industry standard RCA jacks provide an easy connection for signal level input. They are nickel-plated to resist the signal degradation caused by corrosion.
RCA Pass-Thru Jacks
This Pass-Thru provides a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of the vehicle to the rear amplifier location.
The input gain control is preset to match the output of most source units.
Allows you to select the output phase of the amplifier between 0 degrees and 180 degrees.
Variable Low Pass Crossover
Determine which frequencies you feed your subs with the built-in 12dB/octave Butterworth filter, with a crossover point variable from 40Hz to 130Hz.
This is an adjustable Bass level control centered at 45Hz @ 12dB/octave.
Remote Punch Level Control
When connected, the “Gain Control” is linked and allows you to remotely control the output level of the amplifier from the dash or center console.
