The Hikvision DS-QAE0A240G1-VB6/EU is a professional-grade 240W analog amplifier designed for six-zone public address systems, making it ideal for public, commercial, or institutional environments. It offers flexible audio management with two 6.5 mm microphone inputs, two auxiliary (AUX) inputs, an emergency (EMC) input, and support for digital audio sources via Bluetooth, USB 2.0, and SD card. Output options include constant voltage at 70V and 110V, constant impedance from 4 to 16Ω, six zone outputs, and a line output, allowing seamless integration into complex audio systems. The amplifier features independent volume control for each zone and input source, including dedicated bass and treble adjustments, enabling precise and customizable sound control. High-priority microphone and emergency inputs ensure that critical messages are broadcast clearly and without interruption. Built-in protection mechanisms guard against short circuits, overloads, and overheating, while a dynamic limiter circuit protects the connected speakers. A forced-air cooling system with a fan ensures stable, long-term operation. With a frequency response of 80Hz to 18kHz (±3dB), total harmonic distortion (THD) of ≤ 0.5%, and a signal-to-noise ratio (SNR) of ≥ 75dB, this amplifier guarantees high-quality audio performance. Constructed with a durable iron chassis, the unit measures 484 × 88 × 360 mm and weighs approximately 10.3 kg. It is designed for standard rack installation. The package includes the main unit and a power cable. The device operates on a 200V to 230V AC power supply at 50/60Hz and is suitable for use in ambient temperatures ranging from -10°C to +40°C, with a relative humidity of 20% to 80%.
