4 channel power amplifier 600W 70/100V Class D 2U rack - AUDIOPHONY PA AMP4600

The AMP4600 is a 4-channel power amplifier designed for medium to large 70/100 V systems requiring high power, energy efficiency, and multi-zone management. Each channel delivers 600 W, allowing for independent, room-adapted power levels for multiple zones. Class-D technology ensures high efficiency and low heat generation, while thermoregulated ventilation maintains optimal temperature without generating unnecessary noise. The frequency response covers the entire 20 Hz to 20 kHz spectrum with less than 0.05% distortion and a signal-to-noise ratio greater than 100 dB. The auto-standby system reduces power consumption by automatically switching to sleep mode after 15 minutes of inactivity, instantly reactivating when a signal is present. The essential controls — levels and 80 Hz HPF — are located on the rear panel to prevent accidental adjustments, while the front panel features LED indicators to monitor the operating status of each channel. Euroblock connections simplify installation and ensure long-term reliability. The 2U rack format and low weight of 8 kg facilitate integration into technical cabinets and professional infrastructures. User benefits High power for multi-zone installations Low heat generation and temperature-controlled ventilation Automatic standby for energy savings Front LED indicators for immediate monitoring Multiple protections: short circuit, open circuit, overheating, limiter, HF and RF Areas of use Commercial spaces Sports facilities Convention centers and public areas 70/100 V multi-zone installations
