Description
The AD400E converts 4 channels of balanced / unbalanced microphone / line-level audio signals into Dante packets to work with Dante-compliant equipment. It is also AES67 compliant, elevating interoperability between different audio networking protocols and devices. The unit supports 24 bit and offers sampling rate options of 44.1k, 48k, 88.2k, and 96 kHz to meet different commercial-grade application needs. The professional preamp circuitry AD400E comes with delivers a wide dynamic range, high signal headroom, and great Signal-to-Noise Ratio (SNR). Phantom power (+48V) can be enabled on any individual input, supporting condenser microphones while causing little signal distortion.
The built-in DSP allows 24 presets and quick setting adjustment through the PC-based app Audio Wizard / ATEN VK control system via LAN / RS-232. Plus, the unit comes with a selectable automatic Standby Mode for energy-saving purposes, switching the AD400E to Standby Mode automatically when the signal level runs lower than -50 / -60 / -70 dBu for a selected duration (10 / 30 / 60 minutes), allowing the system to consume less power. The AD400E enables redundancy operation thanks to its PoE functionality, eliminating the need for additional cable installations. Furthermore, with the support for Dante Daisy Chaining, the AD400E helps simplify system infrastructure wiring. All the features come in a compact half-rack size enclosure, and consequently, less rack space is needed and installation under desks or on any flat surface is made easy.
Not only does the AD400E enhance interoperability among AoIP devices and allow for effective Pre-AMP processing , it also realizes distributed DSP systems when working with ATEN Pro Audio models, elevating installation flexibility, reducing overall cost, and broadening applications. It is suitable for professional audio scenarios utilizing the Dante networking technology, such as boardrooms, conference rooms, and hospitality venues such as restaurants and bars.
