The SW VGA Series of switchers consists of five models in sizes from two to

twelve inputs. SW VGA Series switchers allow multiple high resolution computer

or HDTV component video signals to be switched to one or two displays. They

are ideal for small to mid-sized applications where high resolution switching

is needed.

The SW VGA Series are VGA switchers with two, four, six, eight, and twelve

■ 350 MHz (-3dB) RGB video bandwidth – Offers the performance required

computer video and HDTV component video signals must be switched to one

or two displays. The SW VGA Series switchers are ideal for small to mid-sized

■ Compatible with VGA-QXGA and HDTV component video signals

applications where high resolution switching is needed. There are several key

features common to all models in this series which benefi t integrators and

end-users, alike.

All models feature input signal sensing, which automatically detects which

inputs have an active signal and reports that information through the RS-232

port for confi rmation of active inputs on third party control systems. This offers

quick confi rmation of active inputs on any third-party control system. Another

■ Switches balanced and unbalanced stereo audio

■ Active PC audio buffering – converts unbalanced PC audio to balanced, line

■ Compatible with Extron VSW I AAP – The optional VSW I AAP provides

feature common to all models is Auto-input switching, which automatically

switches to the highest-numbered input with an active video signal. All

■ Multiple control options – Switcher operations can be controlled through

switchers in this series can also be controlled via their front panel, RS-232, and

contact closure remote control, and via the optional Extron IR 102 handheld

remote control. All of the

SW VGA

models are housed in 1U, rack-mountable

metal enclosures, for easy integration into new or existing A/V environments.

All SW VGA Series switchers feature active PC audio buffering, which converts

unbalanced PC audio to balanced, line level signals, eliminating noise over

long cable runs. The switchers accept PC audio input on 3.5mm mini stereo

jacks for fast, easy connection with pre-terminated Extron VGA and Audio

cables. Balanced or unbalanced audio is output on captive screw connectors.

■ IR control – The SW VGA Series switchers can be conveniently controlled via

power supply provides worldwide power compatibility.

The SW8 VGA and SW12 VGA Series feature dual buffered video and audio

outputs which simultaneously output program video and audio on two parallel

outputs. This eliminates the additional cost of a VGA & audio distribution

amplifi er for dual-display applications.

■ Eight and twelve inputs

■ Audio output volume control via RS-232 – Eliminates the need for a

separate audio preamp in many system designs.

■ Dual buffered video and audio outputs – Simultaneously output program

video and audio on two parallel outputs, eliminating the additional cost of a
VGA & audio distribution amplifi er for dual-display applications.

■ 1U, full rack width metal enclosure
