Description
The Z Audio EX-8500 Professional Power Amplifier is engineered for demanding sound applications requiring high output, clarity and dependable performance. Its Class H output circuitry provides efficient power delivery for professional PA systems, live events, auditoriums, clubs and commercial audio installations.
The EX-8500 delivers 2 × 2000W at 8Ω, 2 × 3000W at 4Ω and 2 × 4000W at 2Ω in stereo mode. For applications requiring greater single-channel power, it provides 6300W at 8Ω bridge and up to 8500W at 4Ω bridge.
With a frequency response of 20Hz–20kHz, signal-to-noise ratio of ≥100dB and THD+N below 0.08% at 1kHz, the amplifier supports clean and balanced sound reproduction. Its ≥950:1 damping factor helps maintain controlled speaker performance, especially in high-power sound systems.
The amplifier includes protection against over-current, DC output, overheating and short circuits. The main power section is also fuse-protected to support safer and more reliable operation.
