● Description
The Extron MLS 103 SV MediaLink Switcher is a compact, three input, one output active switcher. It comes with four audio inputs on captive screw connectors and includes preamp volume control. Inputs one through four provide unbalanced audio while an additional input is an active auxiliary line level mono audio input that can be mixed with any of the other four selectable inputs. When used with a MediaLink Controller, input switching and volume are easily achieved via the controller's user interface. The MLS 103 SV, with three inputs and one output on 4-pin mini DIN connectors, can be controlled via the front panel input buttons or RS-232.
Part of the Extron VersaTools® line of products, the MLS 103 SV is housed in a quarter rack width metal enclosure, making it ideal for installation in podiums and other small space areas. Because of its small size, the switcher can also be mounted or placed on a shelf along with a VCR and DVD player.
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.
● Features
Bandwidth - 250 MHz (-3 dB) video bandwidth maintains signal integrity.
Four audio inputs - The MLS 103 SV offers four switchable audio inputs, each with independent gain and attenuation, on captive screw connectors.
Auxiliary/Mix audio input - An additional input accepts mono line level audio signals for mixing with any of the four switchable inputs.
RS-232 controllable - Switcher control is available through front panel buttons or RS-232. RS-232 control is provided via Extron's Windows®-based control software and/or a third party control system using Extron's Simple Instruction Set™ (SIS™). When the switcher is used with a MediaLink Controller for low-cost system integration, all of the MLS 103 SV's I/O switching and volume control can be remotely controlled.
Rack-mountable - The MLS 103 SV is housed in a 1U, quarter rack width metal enclosure.
External international power supply included (part# 70-055-01)
