SWR-2755 Switchers (Input, Output & Unbalanced)
Audio Precision offers three models of the SWR-2755 audio
switchers: the SWR-2755M Output Switcher (balanced male
XLRs), SWR-2755F Input Switcher (balanced female XLRs)
and SWR-2755U Unbalanced Switcher (floating unbalanced
BNCs).
All models are 12 X 2 with ability to cascade up to 16 units for
a maximum of 192 channels. Generator outputs can be routed
to any of the 12 channels. Inter-channel crosstalk is less than
–150 dB at 20 kHz in the balanced models.
PSIA-2722 Programmable Serial Interface Adapter
This adapter enables the connection of chip-level devices,
such as analog-to-digital converters, digital-to-analog converters
and sample rate converters, to Audio Precision 2700 Series and
System Two Cascade Plus audio analyzers. Devices under test
may have a variety of interface protocols, including different
logic families and voltage levels, clock rates, word orientations,
and formats.
DCX-127 Multifunction Module
The DCX-127 Multifunction Module provides Audio
Precision’s PC-controlled audio analyzers with an interface
toolkit of non-audio functions and interface capabilities that are
often required in typical audio test applications. Applications
include VCA gain control linearity, VCA distortion, amplifier DC
offset and power supply checks, power amplifier load switching
control, loudspeaker voice coil resistance measurements,
temperature measurements, test fixture control, and testing DC
parameters of A/D and D/A converters.
AUX-0025 & APx581 Switching Amplifier
Measurement Filters
The Audio Precision AUX-0025 Switching Amplifier
Measurement Filter is a dual-channel passive filter that provides
the necessary attenuation of out-of-band signals for testing Class
D amplifiers.
The APx581 is an 8-channel version suitable for use with the
multichannel APx585.
