Features
The Extron MLS 406, MLS 406MA, and MLS 406SA MediaLink™
n High bandwidth – 280 MHz (-3 dB) RGB video bandwidth
Switchers are simple-to-use, six input, multi-format active switchers.
Designed as economical solutions for single-display classrooms and
boardrooms, all three models provide composite video, S-video,
n Video inputs – Three female BNC connectors paired with three
computer-video, and audio switching.
MLS - MediaLink Switchers are designed to be used in conjunction
with an MLC - MediaLink Controller to facilitate low-cost integration.
They can also be used as stand-alone switchers.
Line Level Outputs
n Versatile video outputs – Two RGB outputs are provided. One is
Each switcher includes two line level outputs, one fixed and one
variable, that can be configured for mono or stereo output via
RS-232.
Integrated Audio Amplifier
n Local monitor output – 15-pin HD connector can function as
The MLS 406MA provides a 20 watt (rms) amplified mono audio
output for a 4 or 8 ohm load or 70/100 volt distributed audio system.
The MLS 406SA provides 24 watts (2 x 12 watts, rms) into 4 ohm
n Audio inputs – Six balanced/unbalanced stereo audio inputs on
speakers and 16 watts (2 x 8 watts, rms) into 8 ohm speakers. Like the
line level outputs, the integrated audio amplifier can be configured for
default stereo or dual mono output via RS-232.
n Auxiliary/Mix audio input – An additional input accepts mono

4-pin mini DIN connectors for composite video or S-video; three
female 15-pin HD connectors for computer-video, composite
video, or S-video.
available on five BNC connectors and the other on a female 15-pin
HD connector. The 15-pin HD can also be utilized as a buffered
local monitor loop-through for the signal connected to input six.

mini jacks, and one captive screw connector.
line level audio signals for mixing with any of the six switchable
inputs.
MLS 406MA
MediaLink Switcher
with integrated mono
amplifier
The MLS 406 switchers
can be used as stand-alone
switchers, or combined
with an Extron MLC MediaLink Controller to
create an affordable
system integration
solution.
MLC 226 IP
MediaLink Controller
n Balanced audio output – Balanced or unbalanced audio is output
on captive screw connectors. The two line level outputs, one fixed
and one variable, can be set for mono or stereo via RS-232.
n Integrated audio amplifier – The MLS 406MA provides 20 watt
(rms) amplified mono audio output on captive screw terminals
for a 4 or 8 ohm load or 70/100 volt distributed audio system.
The MLS 406SA provides 24 watts (2 x 12 watts rms) for 4 ohm
speakers and 16 watts (2 x 8 watts rms) for 8 ohm speakers.
n Volume control – Is adjustable locally from the front panel or
remotely when integrated with a MediaLink Controller or a third
party RS-232 based control system.
n Loudness control – Boosts low and high frequencies to
compensate for the normal decreased hearing ability of the human
ear at low volume levels.
n Triple-Action Switching™ – Blanks the screen during switching of
RGB signals to eliminate visible switching transitions.
n Front panel security lockout – Allows security lockout of front
panel buttons and/or volume adjustment.
n Control options – The MLS Series switchers are designed to work
with a MediaLink Controller. They can also be controlled via the
front panel or any third party RS-232 control system.
n Rack-mountable – Housed in 1U, full rack width metal enclosures.
n Internal international power supply
