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.
Features
Dante AoIP technology – replaces heavy, costly analog audio cables with cost-effective, easy-to-manage Cat cables
AES67 compliant
Converts 4 channels of balanced / unbalanced microphone / line-level audio signals into Dante packets
Supports 24 bit and offers sampling rate options of 44.1k, 48k, 88.2k, and 96 kHz
Euroblock connectors come with the package for analog input connection
Professional preamp circuitry – delivers a wide dynamic range 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
Parallel Compression – 4 additional channels serve as side chain inputs, combining an original signal with a compressed copy to polish the sound
Built-in DSP – allows 24 presets and quick setting adjustment through PC-based app Audio Wizard / ATEN VK control system via LAN / RS-232
Selectable automatic Standby Mode – the unit enters Standby Mode automatically when the signal level runs lower than -50 / -60 / -70 dBu for a selected duration (10 / 30 / 60 minutes)
Supports PoE for redundancy operation and eliminating the need for additional wiring installations
Supports Dante Daisy Chaining for simplifying system infrastructure wiring
Compact half-rack size chassis – flexible installation inside racks and easy placement under desks or on flat surfaces
Works with ATEN Pro Audio models to realize distributed DSP systems
