Peavey CS 4080 HZ Dual-Channel Professional Power Amplifier

The Peavey CS 4080 HZ is a highly robust, 2-rack-space (2RU) professional stereo power amplifier engineered to deliver massive, clean output power for large-scale sound reinforcement applications, live concerts, touring rigs, and permanent venue installations. Building on the legendary reliability of the classic CS series, this generation utilizes an efficient Class-H topology paired with a high-capacity power supply and a massive central toroidal transformer to optimize efficiency and minimize excess heat generation.It is heavily shielded inside a rugged 16-gauge steel chassis equipped with cast front panel handles for secure mobile handling. Audio performance and hardware longevity are preserved via a suite of protective circuitry, most notably Peavey’s proprietary DDT (Distortion Detection Technique) anti-clipping compression, which prevents destructive speaker distortion under heavy drive. High-velocity thermal management is handled by two temperature-dependent, variable-speed back panel DC fans that draw air through tunnel-cooled heat sinks to keep output transistors at safe temperatures.Key SpecificationsPower Output (Stereo Mode): 2,040 Watts RMS per channel at 4 Ohms; 1,250 Watts RMS per channel at 8 OhmsPower Output (Bridged Mono Mode): 4,080 Watts RMS at 8 OhmsAmplifier Topology: Class-H DesignFrequency Response: 10 Hz to 100,000 Hz (+0/-1 dB at 1 Watt)Damping Factor (8 Ohms): Greater than 500:1 (20 Hz to 1,000 Hz)Input Impedance: 15 kΩ BalancedInput Sensitivity: 2.25 V (±3%) for 4 Ohm rated powerHum and Noise: Greater than -108 dB (A-weighted, referenced to rated 8 Ohm power)Slew Rate: 15 V/µsInput Connectors: 2 x Combination XLR and 1/4-inch TRS inputsOutput Connectors: 2 x Neutrik Speakon connectors and 2 x Binding Post speaker outputsFront Panel Controls: Main AC power switch, Channel A and Channel B attenuation knobsFront Panel Status LEDs: 2 x DDT (clip limiting), 2 x Signal Presence, 2 x Active Status/PowerProtection Circuitry: DDT compression, LFC
