Midas DL252

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 414 mm deep x 221 mm high (19.0" x 16.3" x 8.7"), with nominal weight 10 kg (22.05 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.

PRO SERIES DL252

DL252 is a 5U 19" fixed-configuration rack I/O unit with 16 mic/line level inputs and 48 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 three AES50 network ports providing N+1 redundancy, plus an Ethernet control port and a MIDI Interface (In, Out, Thru), the DL252 is the ideal partner to the Midas M32 Series and PRO Series digital consoles, enabling a digital snake connection from Front of House to stage.

Award-Winning MIDAS Microphone Preamplifier

The Midas microphone preamplifier is considered by leading live sound and recording engineers to be the very essence of the famous Midas sound. More than 40 years of design experience paired with the finest choice of premium-grade components lead to the acclaimed warmth and depth - bringing out subtle ambience, maintaining spatial positioning and more effectively capturing a precise sound image. The acclaimed sound of the award-winning Midas microphone preamplifier has inspired generations of live sound engineers to their best work, creating sonic panoramas that have captivated audiences worldwide. Since pristine sound always begins with the microphone preamplifier, the first point where the signal enters the console, DL252 features the latest generation of Midas microphone preamplifiers, which faithfully reproduce every sonic detail so no part of a performance will ever be missed. Transparent and pristine sound, low noise and high common-mode rejection are all hallmarks of this classic design. Over the years many mix engineers have found this robust and overload-tolerant design takes on a whole new dimen
