PRO SERIES DL152
DL152 is a 2U 19" fixed-configuration rack I/O unit with 24 line level outputs and delivers legendary Midas sound quality utilising our time-tested and road-proven technologies. Featuring two AES50 network ports providing dual redundancy, the DL152 is the ideal partner to all Midas PRO and M32 an Heritage Series digital consoles, enabling a digital snake connection from Front of House to stage.

Digital Audio Networking
SuperMAC (AES50-Compliant) digital audio networking technology from Klark Teknik simultaneously provides high channel counts, ultra low and deterministic latencies, sample-synchronous and phase-aligned networked clock distribution, error detection and correction, network redundancy, and ease of deployment and use – to meet the demanding requirements of live concert touring.

DL152 is compatible with all Midas digital consoles and audio system engines, as well as with any other AES50-equipped devices.

High Output Drive Line Outputs with Mute
DL152 features 24 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.

96 kHz or 48 kHz Operation
DL152 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 DL152 can be set either remotely from the mixing console, or directly via the intuitive and easy to understand front panel. DL152 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 DL152 is designed for the rigours of live concert touring. Premium industry-standard connectors are used for reliable audio and network connections, night after night.

Auto-Ranging Universal Switch-Mode Power Supply
DL152 features a universal power supply, which is auto-voltage sensing for use on a worldwide basis.

Dual Redundant Universal Switch-Mode Power Supplies
DL252 features dual-redundant power supplies, which are auto-voltage sensing for use on a worldwide basis and provide seamless switchover in the unlikely event of a loss of one power supply.

Architecture & Engineering Specifications
The interface unit shall be designed for digital audio mixing applications and be optimised for use in live performance. It shall feature 16 integrated microphone preamplifier inputs with 2.5 dB analogue gain steps and 48 servo-balanced electronic outputs on industry-standard XLR connectors and shall be capable of operating at 48 kHz and 96 kHz sampling rates.

The interface unit shall include a recessed switch on the rear panel to mute all outputs.

The interface unit shall support a 100 Megabit Ethernet frame-based digital audio network that shall offer N+1 cable redundancy and be compliant with the Audio Engineering Society AES50-2011 standard. Three digital audio network ports and one Ethernet control port shall be provided. An industry-standard MIDI Interface (In, Out, Thru) shall also be provided.

The interface unit shall provide both front panel and remote network configuration of operational settings and provide LED status of power supply output rail condition, digital audio and control network connection status and activity, clock synchronisation source, unit identification and communication mode setting.

The interface unit shall include two auto-ranging universal switch-mode power supplies with dual redundancy for use on a worldwide basis.

The interface unit shall be housed in a standard 5U 19" rackmount chassis, and shall be 483 mm wide x 413 mm deep x 222 mm high (19.0" x 16.3" x 8.7"), with nominal weight 14.3 kg (31.5 lbs). The interface unit shall be installed in a rack frame or road case capable of safely supporting its weight. Input, output, and power connections shall be made at the rear panel of the interface unit. Installers shall allow adequate space at the rear for connection and disconnection of input, output, and power connections. The power requirements shall be 100 to 240 VAC, 50 to 60 Hz.

The interface unit shall be the MIDAS DL252 and no other alternative shall be acceptable.
