  SWR-2755 series Switchers

Audio Precision’s new series of APIB-controlled audio switchers are now available.

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 current AP 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 compliances. Manufacturing economies enable us to offer the new switchers at a significantly lower price.
 

SWR-2755 features

• Input and output configurations enable switching of generator outputs or analyzer inputs, or both.

• Balanced and unbalanced configurations are available.

• Multilple 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.

SWR-2755 Configurations

SWR-2755M Output Switcher
12 X 2 configuration

Can route either of the two generator output channels (A & B) to any of 12 channels

Up to 16 units can be cascaded to allow up to 192 channels to be accessed

XLR connectors for balanced signals or, using adapters, unbalanced signals

Complement mode allows all but one channel to be driven while measuring the undriven channel for worse case crosstalk on multichannel devices
 

SWR-2755F Input Switcher
12 X 2 configuration

Can route either of the two analyzer input channels (A & B) from any of the 12 channels

Up to 16 units can be cascaded to allow up to 192 channels to be accessed

XLR connectors for balanced signals or, using adapters, unbalanced signals

SWR-2755U Unbalanced Switcher
12 x 2 configuration

Can be used as either an input or output switcher (by dip switch on rear panel)

Up to 16 units can be cascaded to allow up to 192 channels to be accessed

Floating BNC connectors for unbalanced signals prevent ground loops
