DL351 is a 7U 19" modular con gurable

rack mount I/O unit with provision for

8 DL4 Series interface cards, which

can provide up to 64 audio inputs

and 64 audio outputs. With four

AES50 network ports providing N+1

redundancy, plus an Ethernet control

port and a MIDI Interface (In, Out,

Thru), the DL351 is the ideal partner to

all MIDAS PRO Series digital consoles,

enabling a digital snake connection

from Front of House to stage.

Modular Expansion Cards

Five DL4 Series card options are available
for DL351:

• DL441 - 8 Analogue Mic/Line Input Card

with MIDAS Microphone Preampli ers

• DL442 - 8 Analogue Line Output Card

• DL443 - Analogue 8 Input, 8 Output Card

with ¼ " TRS Connectors

• DL444 - Analogue 8 Input, 8 Output Card

with MIDAS Microphone Preampli ers
and D-Type Connectors

• DL452 - AES3 Digital 8 Input, 8 Output

Card with Sample Rate Conversion

Digital Audio Networking

SuperMAC (AES50-Compliant) digital audio networking technology from KLARK TEKNIK
simultaneously provides high channel counts, ultra low and deterministic latencies, sample­synchronous 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.

DL351 is compatible with all MIDAS PRO Series digital consoles and audio system engines, as well as
with any other 96 kHz-enabled AES50-equipped devices.

Remote Console or Front Panel Control

All con guration settings for DL351 can be set either remotely from the mixing console, or directly
via the intuitive and easy to understand front panel. DL351 features a front panel LCD display with
intuitive menu navigation for all con guration 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.

External Control Ports

DL351 features two General Purpose (GPIO) 25-pin D-type connectors for external device control,
one for inputs and the other for outputs, which are opto-isolated to ensure galvanic isolation and
avoid ground loops. External trigger events received via the input port are relayed to the PRO Series
control centre, and external devices can in turn be triggered from the output port in response
to scene change messages inserted in the console automation show  le running in the control
centre. An industry-standard MIDI interface (In, Out, Thru) is also provided to send and receive MIDI
messages which can also be used in conjunction with the control centre’s automation system.

Architecture and Engineering Speci cations

The interface unit shall be designed for digital audio mixing applications and be optimised for use in live performance. It shall feature a modular

construction, allowing for 8 proprietary format interface cards, providing up to 64 audio inputs and 64 audio outputs and shall be capable of

operating at 96 kHz sampling rate.

The interface unit shall support a 100 Megabit Ethernet frame-based digital audio network that shall o er N+1 cable redundancy and be

compliant with the Audio Engineering Society AES50-2011 standard. Four digital audio network ports and one Ethernet control port shall

be provided.

The interface unit shall include two General Purpose (GPIO) 25-pin D-type connectors for external device control, one connector for inputs and

one connector for outputs, both of which shall be opto-isolated to provide galvanic isolation. An industry-standard MIDI Interface (In, Out, Thru)

shall also be provided.

The interface unit shall provide both front panel and remote network con guration of operational settings and provide an alphanumeric LCD

display with associated menu navigation buttons, and LED status indication of power supply output rail condition and digital audio and control

network connection status and activity.

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 7U 19" rackmount chassis, and shall be 483 mm wide x 416 mm deep x 310 mm high

(19.0" x 16.4" x 12.2"), with nominal weight 16.9 kg (37.2 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 DL351 and no other alternative shall be acceptable.
