PIE Line Driver & Pre-Amplifier LD-1PIE Line Driver & Pre-Amplifier LD-1

Is the volume output of your XM Receiver too low? Use this adapter to boost the XM volume to match your other components.

The LD-1 is a low noise line driver/pre-amplifier for boosting the RCA output of the radio or other line level device.

Features: independent left and right channel level adjustments and built-in 10hz subsonic filter. The LD-1 is a compact line driver/pre-amplifier that boosts the RCA level output of a head unit or other line level device. Independent left and right channel level adjustments allow the user to increase signal gain from the head unit (or other line level component) to the amplifiers. The line driver will boost the RCA output from 0 to +18 db with virtually no distortion (less than 0.005% thd), thus providing the amplifier with a strong clean signal.

The LD-1 enables the installer to precisely match the gain levels between components to optimize overall system performance. The LD-1 may be used before the amplifier input, or between the head unit and other auxiliary sources with low line level outputs, thus preventing one source from being significantly louder than another source. A built-in subsonic filter rolls off frequencies below 10 hz to protect woofers from damage due to over-excursion (over-excursion happens when ultra-low frequencies push speaker cone beyond its mechanical limits).

This product requires a 12V power source from your vehicle.

PIE 5-Amp Power Noise Filter NF-5PIE 5-Amp Power Noise Filter NF-5

The NF-5 in-line power supply Noise Filter eliminates noise generated by the alternator and charging system of the vehicle. Ever since automobiles were invented, the vehicle's chassis has been used as a common ground return for its electrical charging system. The point on the chassis where an audio component is grounded may be anything but quiet; alternator whine or other electrical noises can be "picked up" by the sensitive component. In a perfect world, every manufactured mobile audio component would be designed with enough power supply filtering. But "visions of perfection tend to disappoint." So installers are faced with installing vulnerable audio components in an electrically hostile environment: a two-fold problem which translates to... NOISE!

Using the highest quality components and passive circuitry, PIE's NF power lead filters will eliminate unwanted noise due to alternating current fluctuations, resulting in a quiet audio system, free of alternator whine and other vehicle accessory noise (e.g., ignition, windshield wipers, etc.). Heavy-gauge wire leads and heavy-duty potted enclosures ensure long-term reliability. Quick and easy to install, just insert the noise filter in-line on the power lead to the component.

This In-Line Power Supply noise filter is rated for up to a 5-AMP load.

Installation wiring:

  • Red - to the positive lead in your vehicle
  • Blue - to the positive lead on your audio device
  • Black - ground
