Overview
PRO SERIES DL251
DL251 is a 5U 19" fixed-configuration rack I/O unit with 48 mic/line level inputs and 16 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 DL251 is the ideal partner to the Midas M 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, DL251 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 dimension of sound when driven hard, the crystal-clear audiophile reproduction giving way to just the right combination of harmonics, a warm and organic sound heard by millions of concert goers and recorded for posterity on countless live albums over the years.
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.
DL251 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
DL251 features 16 active servo-balanced low impedance line level outputs with high output current capability for driving long cable runs.
A recessed ‘Mute All Outputs’ switch on the rear panel allows quiet and safe re-patching of cables, even during a show.
96 kHz Or 48 kHz Operation
DL251 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 DL251 can be set either remotely from the mixing console, or directly via the intuitive and easy to understand front panel. DL251 features front panel switches for all configuration options with LED status indicators, which provide highly visible feedback of operational status over wide viewing angles and distances.
Clear indication is provided of power supply output rail condition, AES50 and Ethernet network connection status and activity, choice of internal or external clock synchronisation, unit identification and communication mode setting.
Built For The Road
Featuring a rugged steel 5U rackmount enclosure, the DL251 is designed for the rigours of live concert touring. Premium Neutrik connectors are used to ensure reliable audio and network connections, night after night.
Dual Redundant Universal Switch-Mode Power Supplies
DL251 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.
