Overview
PRO SERIES DL151
DL151 is a 2U 19" fixed-configuration rack I/O unit with 24 mic/line level inputs and delivers legendary Midas sound quality utilising our timetested 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 DL151 is the ideal partner to all Midas PRO and M32 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, DL151 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
DL151 is compatible with all Midas digital consoles and audio system engines, as well as with any other AES50-equipped devices.
96 kHz or 48 kHz Operation
DL151 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 DL151 can be set either remotely from the mixing console, or directly via the intuitive and easy to understand front panel. DL151 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 DL151 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
DL151 features a universal power supply, which is auto-voltage sensing for use on a worldwide basis.
