Reiss RS-Z475.4D – 4-channel Class D amplifier 475W x4 @ 4 Ohm with extreme performance

Reiss RS-Z475.4D is a uncompromising Class D 4-channel amplifier developed for powerful audio systems where high output, precision, and control are essential. With a massive 475W RMS per channel at 4 Ohm, it delivers serious power to midbass drivers, midranges, or full-range systems without sacrificing stability.

At 2 Ohm, the output increases to an impressive 4x760W RMS, and when bridged the amplifier delivers a huge 2x1520W RMS. This makes the RS-Z475.4D an extremely flexible amplifier for both SPL-oriented installations and advanced systems with demanding power requirements.

The wide frequency range of 20–20,000 Hz provides clear and dynamic reproduction across the entire spectrum. With advanced filter settings, the system can be fine-tuned precisely for different installations and speaker configurations:

• High-pass filter: 100–4,000 Hz
• Band-pass filter: 40–400 Hz
• Low-pass filter: 10–400 Hz

The high sound quality is clearly reflected in the impressive signal-to-noise ratio of 110 dB and low distortion of only 0.1%, delivering clean, powerful, and detailed sound even under heavy load.

Thanks to the efficient Class D design, you get high output power with excellent efficiency and lower heat generation compared to traditional amplifier solutions. This makes the RS-Z475.4D highly suitable for long and demanding listening sessions.

Reiss RS-Z475.4D is the perfect choice for those seeking extreme power, advanced tuning capabilities, and high sound quality in a powerful 4-channel amplifier built for serious audio builds.
