Expert Electronics PX1 R Line 4-Channel Car Audio DSP

Shape your car audio system, channel by channel

The Expert Electronics PX1 R Line combines digital audio processing, equalization, and crossover controls in a compact aluminum chassis. With four channels, an 11-band input equalizer, and one parametric EQ band per channel, it gives your installer tools to tailor a compatible car audio system.

Connection and Filter Verification

The source also lists crossover attenuation from 6 to 48dB with unclear slope notation; verify the precise settings in the manual.

Compatibility and Installation

This unit processes audio signals; it is not a power amplifier and does not directly drive speakers. Use it with compatible source equipment and external amplifiers.

Professional installation and tuning are recommended. Verify power requirements, signal connections, routing, and filter settings against the manufacturer's documentation. Configure gain and limiter settings according to the connected equipment; a limiter does not guarantee protection from incorrect setup or speaker damage.
