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 current 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.
Built with the same feature set and solid integrity of the SWR-2122, the new SWR-2722 series bring significantly lower crosstalk (18 dB better in an unbalanced 600 Ω load; 10 dB better in a balanced 600 Ω 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.
* 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"). switchers can be used on the bench or rack mounted with an optional rack mount adapter kit.
