Phoenix Gold ZQ9004

The Phoenix Gold ZQ9004 is designed for discerning car audio enthusiasts who prioritize sound quality, power reserves, and a high-quality analog amplifier design over an abundance of adjustment options. The 4-channel power amplifier uses Class A/B technology and delivers up to 4 × 230 watts RMS at 2 ohms.

With the ZQ9004, Phoenix Gold has deliberately opted for a sophisticated design and carefully selected components. These include a dual-power supply, a two-layer printed circuit board with immersion gold plating, shielded transformer cores, and high-quality capacitors from Nichicon and Wima. The transistors are manufactured by Toshiba and ON Semiconductor.

The commitment to high quality is also consistently reflected in the connections: The power amplifier features 24-karat gold-plated terminals. High-quality polymer gain potentiometers allow for precise adjustment of the input signal.

With a frequency range up to 55 kHz, a signal-to-noise ratio of over 110 dB, and a total harmonic distortion of less than 0.05%, the ZQ9004 is designed specifically to deliver clean and detailed sound reproduction. Thanks to its high output power, it is suitable for both high-performance front and rear systems as well as for demanding multi-way installations.
