The ATEN AD400E DSP Mixer with 4-ch Dante Input is a compact Dante-to-analog audio processor that converts Dante network audio into 4-channel analog line outputs, making it easy to integrate digital AoIP sources with traditional analog audio equipment. Powered by an embedded SHARC® ADSP-21489 DSP, it supports 24-bit audio with selectable sampling rates of 44.1 / 48 / 88.2 / 96 kHz, and includes a built-in DSP matrix mixer for flexible routing of Dante inputs to any output. Control and speaker functionality management are available via the PC-based Audio Wizard or the ATEN VK control system over LAN / RS-232, with support for 24 presets. With AES67 compliance, PoE redundancy, and selectable automatic Standby Mode for energy saving, the AD400E is ideal for professional audio deployments in boardrooms, conference rooms, and hospitality venues such as restaurants and bars.

Key Features

• Dante to 4-Channel Analog Output Conversion: Converts Dante inputs into 4-channel analog line outputs to bridge AoIP and analog audio systems.
• Dante AoIP over Cat Cabling: Uses Dante networking to replace heavy, costly analog audio cabling with cost-effective Cat cables.
• Built-in DSP + 24 Presets: Integrated DSP supports 24 presets and speaker functionality management via Audio Wizard / ATEN VK over LAN / RS-232.
• DSP Matrix Mixer: Assigns Dante inputs to any of the four analog outputs for flexible mixing and routing.
• AES67 Compliant: Improves interoperability with other audio networking protocols and devices.
• Selectable Auto Standby Mode: Automatically enters standby when signal drops below -50 / -60 / -70 dBu for 10 / 30 / 60 minutes (selectable).
• PoE for Redundancy: Supports PoE for redundancy operation and reduced wiring requirements (external power can be used as backup).
• Compact Half-Rack Chassis: Space-saving enclosure suitable for rack installation, under-desk mounting, or placement on flat surfaces.
• Scales with ATEN Pro Audio: Works with ATEN Pro Audio models to help realise distributed DSP systems for flexible, cost-effective installs.

What's Included

• (1) ATEN AD400E DSP Mixer with 4-ch Dante Input
• (1) User Instructions
• Note: External power adapter is sold separately and can provide redundant power if PoE becomes unavailable.
