Audio Precision SWR-2755M

Audio Switcher

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.
