  • Page 2: Important Safety Instructions

    Thank you for purchasing this PR-1500.1M amplifier. We hope that these amplifier will bring you years of performance and reliability. Please read this manual carefully for proper use of your PR-1500.1M amplifier. Should you need technical assistance, please contact us via email sales-1@proreck.com.
  • Page 3 · Sensitivity: 103dB @ 1w/1m Features MUTE CIRCUIT: The PR-1500.1M amplifier features an anti-thump, mute and delay circuit. This eliminates the noise generated when the power amplifier is turned on and off. BASS EQUALIZATION CIRCUITRY: A narrow ”Q” shelving equalization circuit is included in the amplifier. The equalization system is preset at 45Hz.

  • Page 4: Mounting And Wiring

    circuit constantly monitors the heat sink internal temperature and various voltages, adjusting the amp automatically and protecting it from dangerous conditions. The 2 LED's located on the side of the amplifier provide indication of the amplifier status, the Power LED will light when the amplifier is receiving proper power, ground and remote voltages and the IC monitoring sequence indicates the amp is functional.

  • Page 5: Wiring The Amplifier

    WIRING THE AMPLIFIER: 1. The PR-1500.1M amplifier is supplied with a built-in fuse, never replace the fuse that the amp came with, with one of a larger value. We suggest you construct a Red wiring harness with 2 additional fuses. One fuse should be located near the car battery. This fuse near the battery offers protection against damage from short circuits to the car chassis between the battery and the amplifier.
  • Page 6 Radio Remote position. Woofer configuration The PR-1500.1M is a 4 ohm mono block Class A/B amplifier, The final impedance load should not fall below 4 ohm. Multiple woofers can be wired to this amplifier as long as the final impedance is no lower than 4 ohms.

    3.SUBSONIC FILTERING This unit comes with a built in subsonic filter that ranges from 10Hz to 50Hz. For sub woofer installations with a passive LP crossover you can set the amplifier's CROSSOVER MODE selector to Full Range while setting the SUBSONIC KNOB to 30Hz, this will filter all signals below 30Hz.
  • Page 8 problem Cause/solution 1. Short-circuit protection - Caused by the power or ground wire not being fastened Amp goes tightly. Disconnect the speakers from the amp. If the amp is still in protect mode, you into protect now know the issue is somewhere with the power, ground, or remote wire. You mode should check and make sure the ground is tight.
  • Page 9 Amp keeps Main Fuse - If you determine that your main fuse is blowing, then you'll want to pay blowing fuses attention to when it blows. Try inserting a good, properly rated fuse with your head unit—and amplifier—turned off. If the fuse blows immediately, when everything is off, then you're probably dealing with some kind of short in the power cable between the main fuse and the distribution block, or between the main fuse and the amplifier if there is no distribution block in the...
  • Page 10 issue with new speaker wire and see if that solves your issue. You can also visually inspect your current speaker wire. 10. Make sure the positive and negative speaker wire are running to the positive and negative speaker terminal of the amp. If they are reversed, then the speaker will play no sound or very little sound.
  • Page 11 We recommend doing a test with different RCA cables. Replace the RCA cables if needed. 6.Low-quality speaker wires will also cause noise. Were commend you buy high-qual- ity insulated speaker wire made for marine applications. Sound is 1. This can be caused by wiring at too high of an impedance (ohms) and the amp puts too low out low power, at4 or 8 ohms for example.
  • Page 12 6. Each channel on your amplifier has a gain control. Make sure the gain on this channel of the amplifier is turned up.
