16 Input, 8 Output Stage Box with 16 Midas Microphone Preamplifiers.

DL153 is a 2U 19" fixed-configuration rack I/O unit with 16 mic/line level inputs and 8 line level outputs and delivers legendary Midas sound quality utilising our time-tested and road-proven technologies. Featuring award-winning Midas microphone preamplifiers with 2.5 dB analogue gain steps and two AES50 network ports providing dual redundancy, the DL153 is the ideal partner to all Midas PRO and M32 Series digital consoles, enabling a digital snake connection from Front of House to stage.

DL153 features 8 active servo-balanced low impedance line level outputs with high output current capability for driving long cable runs.

The outputs feature an automatic mute facility if the audio signal path is muted by the mixing console operator, and individual LED indicators are provided for each output connector.

Featuring a rugged steel 2U rackmount enclosure, the DL153 is designed for the rigours of live concert touring. Premium industry-standard connectors are used for reliable audio and network connections, night after night.
