Portable One and ATS-1
Portable One audio analyzers bring bench-quality, high-precision
test and measurement to maintenance, engineering and production
facilities. Whether in broadcast, communications, bench or production
use, Portable One offers a complete, easy-to-use audio test set housed in
a rugged fan-cooled clamshell case that’s ready for almost anything.
Designed for rack-mount and production applications, the ATS-1 offers
the same measurement functionality and ease-of-use as an equivalent
Portable One, but is housed in a fan-cooled metal case, designed for
front or rear modular connector placement and rack mounting.
Portable One Plus Access provides comprehensive two-channel
analog generation and measurement. With twelve different
measurement functions selectable at the push of a button, Portable
One is comprehensive while remaining user-friendly. Easy-to-set-up
sweep capability produces graphs of frequency response, distortion vs.
frequency and even amplitude sweeps. Non-volatile storage of up to 30
tests allows easy, one-button recall of your favorite test setup.
Like the 2700 Series, the Portable One audio analyzer is available as a
dual domain instrument providing simultaneous generation and analysis
capabilities in both the analog domain and the digital domain.

ATS-2 Audio Analyzer
The ATS-2 is a general-purpose audio analyzer well suited to the
design lab, broadcast facility or production line—anywhere you
need high-precision, feature-rich audio test and measurement.
The ATS-2 offers an excellent value in audio analyzers. Its
converter-based architecture keeps the cost down while offering a
wide range of features at high levels of performance. Converterbased audio analyzers generate and analyze signals in the digital
domain and use analog-to-digital converters (ADCs) and digital-toanalog converters (DACs) for analog input and output.

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 (oating unbalanced
BNCs).
All models are 12 X 2 with ability to cascade up to 16 units for

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, amplier DC
offset and power supply checks, power amplier load switching
control, loudspeaker voice coil resistance measurements,
temperature measurements, test xture control, and testing DC
parameters of A/D and D/A converters.
AUX-0025 & APx581 Switching Amplier
Measurement Filters
The Audio Precision AUX-0025 Switching Amplier
Measurement Filter is a dual-channel passive lter that provides
