DL155 Stage Boxes Midas

High Output Drive Line Outputs with Mute

DL155 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.

AES3 Digital Audio Interface

DL155 features an 8 channel digital AES3 (AES/EBU) interface with 8 input channels and 8 output channels, each configured as four digital data streams on individual XLR connectors.

DL155 features sample rate conversion for both inputs and outputs and can interface to equipment operating at 48 kHz and 96 kHz. Additionally, DL155 features external clock synchronisation for input channels and word length and clock source options (internal 48 kHz, internal 96 kHz or external synchronisation) for output channels.

Each AES3 input connector has LED indication for synchronisation lock to the incoming digital data stream. The AES3 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.

96 kHz or 48 kHz Operation

DL155 supports multiple sample rates for the AES50 connections - 96 kHz for use with MIDAS PRO Series, and 48 kHz for use with MIDAS M32 Series.

Remote Console or Front Panel Control

All configuration settings for DL155 can be set either remotely from the mixing console, or directly via the intuitive and easy to understand front panel. DL155 features a front panel LCD display with intuitive menu navigation for all configuration options with LED status indicators, which provide clear feedback of operational status over wide viewing angles and distances. Clear indication is provided showing power supply output rail condition and AES50 and Ethernet network connection status and activity.

Built for the Road

Featuring a rugged steel 2U rackmount enclosure, the DL155 is designed for the rigours of live concert touring. Premium Neutrik connectors are used for reliable audio and network connections, night after night.

Auto-Ranging Universal Switch-Mode Power Supply

DL155 features a universal power supply, which is auto-voltage sensing for use on a worldwide basis.
