Hikvision IP Audio Processor 8 × 8 Network Audio, 8 × 8 Analog Audio (DS-QAPPR1-N)

The DS-QAPPR1-N provides flexible audio routing and processing for professional AV installations. It supports 8 network audio inputs and 8 network audio outputs, together with 8 + 8 analogue channels, including additional configurable channels.

Its 64-bit DSP platform operates at 48kHz, with 32-bit A/D and 24-bit D/A conversion. Extensive processing includes 12-band parametric EQ, 31-band graphic EQ, high/low-pass filtering, compression, expansion, noise gate, AGC, acoustic echo cancellation, automatic noise suppression, feedback suppression, ducking, matrix mixing, auto mixing, delay and phase inversion.

The processor supports AES67 and Dante-compatible network audio environments, while its USB Type-A port supports audio recording and the USB Type-C interface can operate as a sound card. Master/slave hot backup, remote meetings, speech-to-text, recording/playback and video-tracking applications are also supported.
