The DS-QAPPR2-N provides a powerful DSP platform for complex professional audio systems. It supports 16 network audio input channels and 16 network audio output channels, together with 16 analogue input and 16 analogue output channels, plus an additional eight flexible custom channels. Hikvision also specifies compatibility with Dante-based network audio ecosystems through its AES67 network transmission solution.
Its 64-bit DSP architecture operates at 48kHz, with 32-bit A/D and 24-bit D/A conversion. Processing functions include AEC, ANS, AGC, feedback suppression, AutoMix, priority ducking, matrix mixing, 12-band PEQ, 31-band GEQ, compression, expansion, noise gate, delay, filtering and phase inversion.
The unit is equipped with two RJ45 interfaces, RS-232, RS-485, eight GPIO interfaces and two USB interfaces. A USB Type-A interface supports audio recording, while USB Type-C provides sound-card functionality. A built-in 3-inch display and jog dial provide local access to device information and configuration.
