Hikvision Professional Amplifier 500W 2-Channel | DS-QAPAR50-2

The Hikvision DS-QAPAR50-2 is a 2-channel Class D professional power amplifier in a 1U rack chassis. It delivers 2 × 500 W into 8 Ω in stereo mode, or 1 × 1530 W into 8 Ω in bridge mode, takes balanced XLR line inputs and drives passive loudspeakers through SPEAKON outputs.

Key Features:

Efficient Class D Design: A Class D digital amplifier with power efficiency of up to 90%. Less power is wasted as heat, which keeps the unit compact and cooler in a rack.

Stereo or Bridge Mode: Run the two channels independently in stereo (2 × 500 W at 8 Ω, 2 × 765 W at 4 Ω) or bridge them into one higher-power output (1 × 1530 W at 8 Ω). Each channel is controlled independently, and switches select mode, gain and the limiter.

Wide-Range PFC Power Supply: The PFC switching power supply accepts 90 to 260 VAC at 50/60 Hz, so the amplifier keeps working through wide mains voltage variation.

Low Noise and Distortion: Signal-to-noise ratio of 105 dB or more (A-weighted) and typical THD of 0.01%, with a frequency response of 20 Hz to 20 kHz (+0/-0.5 dB).

Built-in Protection: Protection circuits cover over-temperature, DC, short circuit, signal overload, soft start and power-supply over-current, helping protect both the amplifier and the connected speakers.

Quiet Variable-Speed Cooling: The low-noise variable-speed fan stays silent at low temperatures, which reduces noise in the equipment room.

Who it's for / Works with: Sound reinforcement for stages, performance venues and larger spaces that need to drive high-power passive loudspeakers.

Good to know: This is a power amplifier only. It needs a line-level source such as a mixing console or audio processor (maximum input level 14 V) and passive loudspeakers connected by SPEAKON cable; the source, speakers and cables are sold separately.
