| Extron SW2 VGA DA2 A Two Input, Dual Output VGA and Stereo Audio
Switcher with Rear Panel Inputs |
Product Code: SW2VGADA2A
 |
The Extron SW2 VGA DA2 A and SW2 VGA DA2 AF are
combination active switchers and distribution amplifiers with stereo audio. Each
switcher provides two inputs and dual buffered video outputs and PC audio
buffering. Both models are ideal for presentation environments requiring a
furniture-mountable switcher with the added convenience of a built-in
distribution amplifier.
The SW2 VGA DA2 A and SW2 VGA DA2 AF provide 300 MHz (-3 dB) RGB video bandwidth
and are compatible with VGA-QXGA and HDTV component video signals. Dual buffered
video outputs allow for simultaneous viewing and recording of the selected input
signal. Active PC audio buffering allows both models to input unbalanced audio
on 3.5 mm stereo mini jacks, and output unbalanced and balanced audio on captive
screw connectors. Balanced audio signals are much less susceptible to hum and
interference over long cable runs.
The SW2 VGA DA2 A offers all input connections on the back panel while the SW2
VGA DA2 AF offers convenient access to I/O connections from the front panel.
Front panel access makes the SW2 VGA DA2 AF an ideal solution for use in podium
applications where one computer-video source is in a fixed location, and the
second source is a laptop. |
� Inputs: Two female 15-pin HD
connectors for computer video; two 3.5 mm stereo mini jacks for audio
� Outputs: Two female 15-pin HD connectors for computer video; captive screw
connector for audio
� 300 MHz (-3 dB) RGB video bandwidth
� Compatible with VGA-QXGA and HDTV component video signals
� Dual buffered video and audio outputs � Allows for simultaneous viewing and
recording of the selected input signal, eliminating the cost of a separate
distribution amplifier.
� ID bits from inputs 1 and 2 are routed to the local monitor output
� Active PC audio buffering � Converts unbalanced PC audio to balanced, line
level signals, eliminating noise over long cable runs.
� Auto-input switching � Automatically switches to the highest-numbered input
with an active video signal.
� Contact closure remote control
� 1", half rack width metal enclosure
� Highly reliable, energy-efficient external universal power supply included,
replacement part #70-775-01 � Provides worldwide power compatibility, with high
demonstrated reliability and low power consumption for reduced operating costs. |
