MD-4
Sound Devices, LLC
Overview
Sound Devices MD-4 is a simple, high-performance
interface to connect four microphone or line-level
analog sources to Dante™ Ethernet audio networks.
Additionally, four signals on a Dante network can be
output as balanced line-level signals. A selectable
headphone monitor allows either input or output signals
to be monitored in headphones and viewed on level
meters.
The MD-4 offers high-quality audio and reliability for
professional applications. Its four mic/line audio inputs
use standard 3-pin female XLR connectors for easy
interfacing with balanced and unbalanced sources. The
input circuitry offers adjustable gain, 48-volt phantom
power, and high-pass filter functions.
Four digital audio signals on a Dante audio network can
be routed to the MD-4 and converted to balanced, line-
level analog outputs.
The headphone monitor allows for monitoring any input
or output signal, in mono or in pairs in headphones. The
monitored signal level appears on an LED level meter.
Audinate’s Dante audio-over-Ethernet technology has
found wide acceptance because of its ease of use,
interoperability, excellent audio quality, and wide
adoption by a large number of equipment manufactur
-
ers. The MD-4 can serve as an edge device for a Dante
network, providing high-performance input, output, and
monitor resources for applications requiring analog
input and output.
The unit is powered by either AC mains (100-240) or
DC (10-18) VDC sources. If both AC and DC sources are
connected, the AC source acts as primary with the DC
source serving as backup in the event of loss of AC.
The MD-4 chassis mounts in a standard 19-inch equip
-
ment rack (1U) and weighs less than four pounds (2 kg).
Applications
The MD-4 is a general-purpose input, output, and
monitoring device intended for a variety of audio and
audio-for-picture applications that utilize Dante. It is
suitable for use in demanding on-air broadcast and live-
event applications that require both quality audio and
reliable operation. The rack-mounted unit is appropriate
for both fixed installation applications such as stadium,
worship, education, commercial, and government facili
-
ties as well as being suitable for mobile and field uses.
