Audio System Modular I/O (DL451)

The DL451 is a 3U 19” rack unit, which provides a maximum of 24 audio inputs and 24 audio outputs. It has the same user-configurable card format as the DL351 but has the capacity to house up to 3 cards, which can be any combination of 8 analogue mic/line in, 8 analogue out (XLR), 8 analogue TRS line level in and out, 8 digital in and out (4 AES/EBU pairs) or a 25 pin D sub card with 8 analogue mic/line inputs and 8 outputs.

Midi in, out and thru, and GPIO connections are supplied as standard. Digital audio interface is via 2 AES50 ports, one of which can be configured as a spare redundant connection.

The DL451 can be used with the MIDAS XL8 and PRO series of digital mixing systems, or as a stand-alone AES50 audio interface in a MIDAS snake and audio distribution systems with remote control via Ethernet.
