Audio Precision offers three models of the SWR-2755 audio switchers, which expand the 2-channel input and output capabilities of Audio Precision 2700 series and ATS-2 audio analyzers, as well as older System One and System Two instruments.
SWR-2755 switchers replace the SWR-2122 switchers, which have been discontinued. The new switchers are entirely compatible with our current products and offer better performance at a lower price. They also may be used with any discontinued products that originally specified the SWR-2122 or SWR-122 switchers.
Built with the same feature set and solid integrity of the SWR-2122, the new SWR-2755 series bring significantly lower crosstalk (18 dB better in an unbalanced 600 ? load; 10 dB better in a balanced 600 Ohm load), a new universal power supply that automatically adjusts to all line voltages, a convenient rear-panel ground lug and full EMC and safety regulatory compliance. Manufacturing economies enable us to offer the new switchers at a significantly lower price.
Key Features:
Input and output configurations enable switching of generator outputs or analyzer inputs, or both.
Balanced and unbalanced configurations are available.
LEDs indicate the on or off status of each channel.
Multiple switchers can be connected to an Audio Precision analyzer, expanding the system capability to as many as 192 inputs and outputs.
Low inter-channel crosstalk, less than -150 dB at 20 kHz in the balanced configurations.
All switchers are one rack unit (RU) high (1.75 inches). Switchers can be used on the bench or rack mounted with an optional rack mount adapter kit.
