FEATURESDESCRIPTION
The Extr
on
MLS 304MA and MLS 304SA MediaLink™Switchers ar
e simple-to-use, four input, multi-format active switchers with audio amplifiers. Designed as economical solutions for single-projector classrooms and conference rooms, both models provide composite video, computer
-video, and audio switching.
The MLS 304MA and MLS 304SA include two inputs for composite video with ster
eo audio on RCA connectors and two inputs for
computer-video with stereo audio on 15-pin HD connectors and
3.5 mm ster
eo mini jacks. Inputs three and four, both on 15-pin HD connectors, are also configurable for computer-video, as well as composite video. The switchers are equipped with dual RGB outputs. One is on five BNC connectors and the other is on a 15-pin HD connector. The 15-pin HD connector can also be utilized as a buffered loop-through of input number 4 for a local monitor, eliminating the need for a distribution amplifier and simplifying operations.
MediaLink Switchers are designed to be used in conjunction with a MediaLink Controller to facilitate low-cost integration. They can also be used as stand-alone switchers.
Audio
For audio, each switcher includes two line level outputs (one fixed and one variable) that can be configured for mono or stereo output via RS-232. The MLS 304MA provides a 20 watt (rms) amplified mono audio output on screw terminal for a 4 or 8 ohm load or 70/100 volt distributed audio system.
The MLS 304SA provides 24 watts (2 x 12 watts rms) for 4 ohm speakers and 16 watts (2 x 8 watts rms) for 8 ohm speakers. Like the line level outputs, the integrated audio amplifier can be configured for stereo (default) or dual mono output via RS-232.
High
bandwidth –
280 MHz (-3 dB) RGB video bandwidth
maintains signal integrity.
Flexible video and ster
eo audio inputs –
Inputs one and two accept composite video and stereo audio, and are on RCA connectors. Inputs three and four accept computer-video or composite video and stereo audio, and are on female 15-pin HD and 3.5 mm ster
eo mini jacks.
Versatile video outputs – The MLS 304MA and MLS 304SA
include dual RGB outputs. One is on five BNC connectors and the second is 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 four.
Balanced audio – 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.
Integrated audio amplifier – The MLS 304MA 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 304SA provides 24 watts (2 x 12 watts rms) for 4 ohm speakers and 16 watts (2 x 8 watts rms) for 8 ohm speakers.
Auxiliary/Mix audio – An additional input accepts mono line
level audio signals for mixing with any of the four switchable inputs.
Volume control – Adjustable locally from the front panel or
remotely when integrated with a MediaLink Controller or a third party RS-232 based control system.
MLS 304MA
MediaLink Switcher with integrated mono amplifier
The MLS 304 switchers can be used as a stand-alone switcher, or combined with the MediaLink family Controller to create an affordable system integration solution.
MLC 206
MediaLink Controller
Loudness control – A unique audio feature of the MLS 304MA
and MLS 304SA that compensates for the nor
mal decr
eased hearing ability of the human ear at low volume levels by automatically boosting the low and high frequencies.
Triple-Action Switching™(RGB delay) – Blanks the screen
during switching of RGB signals to eliminate visible switching transitions.
ont panel security lockout –
Fr
Allows security lockout of fr
ont
panel buttons and/or volume adjustment.
Remote control – 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 based control system.
Rack-mountable – The MLS 304MA and MLS 304SA are housed
in a 1U, full rack width metal enclosure.
