Description
The Hikvision DS-QAPAR50-4 is a powerful 4-channel Class D professional power amplifier designed to deliver clear, high-performance audio amplification for professional sound reinforcement systems, theaters, auditoriums, event venues, hotels, and commercial audio installations.
Featuring four independently controlled channels, the amplifier delivers 4 × 500W at 8Ω, providing a combined rated output of 2000W in this configuration.
The DS-QAPAR50-4 uses advanced Class D digital amplification technology, delivering high energy efficiency of up to 90%, low distortion, and reliable operation in demanding professional environments.
It supports multiple operating modes, including Stereo, Bridge, and Connect, allowing installers to configure the amplifier for different speaker arrangements and audio system requirements.
In Stereo mode, the amplifier delivers 4 × 765W at 4Ω and 4 × 1301W at 2Ω. In Bridge mode, it provides up to 2 × 1530W at 8Ω or 2 × 2601W at 4Ω for compatible high-power loudspeaker systems.
With a wide 20Hz–20kHz frequency response, typical total harmonic distortion of 0.01%, and a signal-to-noise ratio of ≥105dB, the amplifier delivers clean, detailed audio reproduction with minimal noise.
The amplifier includes four professional XLR audio inputs and four SPEAKON speaker outputs, offering reliable connectivity with compatible professional audio equipment.
Its integrated protection systems help safeguard against overheating, short circuits, DC faults, signal overload, and power supply overcurrent.
The compact 1U rack-mountable design, variable-speed cooling fan, and wide-range 90–260V AC power supply make the DS-QAPAR50-4 suitable for demanding professional audio applications.
