Phoenix Gold ZR6004R

The Phoenix Gold ZR6004R is a high-performance 4-channel amplifier designed for high-end car audio systems. Thanks to modern Class D technology, it combines high output power with compact dimensions and high efficiency. This makes the amplifier suitable for both classic multi-channel systems and performance-oriented front systems.

At 4 ohms, the ZR6004R delivers 4 × 105 watts RMS. At an impedance of 2 ohms, the power output increases to 4 × 175 watts RMS. Alternatively, the channels can be bridged, providing 2 × 350 watts RMS at 4 ohms. This gives the amplifier sufficient headroom for high-output component speakers or other high-power speaker configurations.

For flexible tuning, the ZR6004R features adjustable high-pass and low-pass filters. Both filters can be set within the range of 40 Hz to 6 kHz and operate with a slope of 12 dB per octave. In addition, a bass boost operating at 45 Hz with a boost of up to +18 dB is available.

In addition to low-level RCA inputs, the amplifier also supports high-level signals via the RCA inputs. The built-in Auto-Turn-On feature detects an incoming audio signal and can automatically turn on the amplifier. This makes it easy to integrate the ZR6004R into vehicles equipped with a factory-installed radio or OEM audio system.

The solid aluminum housing also serves as a heat sink. Phoenix Gold does not use an additional fan, allowing the amplifier to operate silently. Protective circuits monitor operation and safeguard the electronics against, among other things, overheating, short circuits, abnormal supply voltage, and reverse polarity.

A wired remote control is included. On the ZR6004R, the Remote Gain Controller allows you to adjust the volume of channels 3 and 4 from the driver's seat.
