Preamplifier converting 4 microphone or line channels into Dante audio-over-IP packets over Cat cabling, with per-channel +48 V phantom power, 24-bit DSP and sampling rates up to 96 kHz; AES67 compliant.

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
Adopts SHARC® processor ADSP-21489 to support 24 bit and offer 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
