Soundking NA02D AES67 Digital Audio Processing Node

Soundking NA02D AES67 Network Audio Input Node
The Soundking NA02D puts analogue audio onto the network: it converts two channels of balanced analogue input into an AES67-compliant digital stream, with powerful per-channel DSP and PoE power in a rugged palm-size chassis. Plug in your sources, process them onboard and send 48kHz/24bit audio anywhere a network cable can reach - the input half of a complete audio-over-IP system for installed AV, conferencing, broadcast and live sound.

Analogue In, Network Audio Out
Two XLR (female) inputs on a flexible breakout tail accept balanced line-level sources up to 18dBu - a mixer's outputs, a media player, a paging feed - while the RJ45 port carries the resulting AES67 RTP stream onto standard IP networks. Conversion runs at 48kHz/24bit with high dynamic range and low noise, and device latency is configurable (1, 2, 5 or 6ms) to suit anything from real-time reinforcement to long distributed runs. Pair it with the Soundking NA02P output node for a complete analogue-to-analogue link across the network, or feed AES67-enabled gear such as Soundking's BD2300 power amplifier directly.

Onboard DSP for Every Input
The NA02D isn't just a converter - each channel carries a full DSP chain you can configure freely: EQ with 1-16 bands, compression, delay, high and low-pass FIR filtering, limiting, expansion and a noise gate. Feedback suppression tames problem frequencies in live rooms, automatic mixing (threshold or gain-sharing) rides the levels of multiple sources hands-free, and matrix mixing plus a built-in signal generator round out routing and system checks. Signals arrive on the network already polished, with no external processor in the rack.

One Cable, Anywhere
Power over Ethernet (IEEE 802.3af) means the NA02D runs straight from a PoE switch or injector - the same network cable that carries your audio also powers the unit, so there's no local power supply at the source end. At 176 x 42.9 x 57.4mm and just 0.3kg, with protective corner bumpers on a rugged chassis, it tucks in behind a lectern, above a ceiling or at the back of a stage for clean single-cable installs in distributed and conference systems.
