                                    System One is manufactured in eight standard configurations
designated by the product nomenclature SYS-xx or SYS-xxx.
The system configuration can be determined from the
following desciptions, or from the connector panel figures
shown on pages 1-2 to 1 -5.

NOTE: The main signal connectors may differ from the XLR
types shown in the figures without changing the system
configuration.

SYS-22 Configuration

Dual channel generator and analyzer system. The upper left
front panel contains the generator output connectors and the
upper right front panel contains the analyzer input
connectors. The lower left front panel contains three BNC
connectors providing auxiliary signals from the generator.
The lower right front panel contains five bnc connectors for
monitoring the analyzer signals and connecting an external
filter. Blank back panels.

SYS-11 Configuration

Single channel generator and analyzer system. Otherwise
virtually identical to the SYS-22.
SYS-20 Configuration

Dual channel generator only system with identical
functionality as the SYS-22. The upper right front panel
contains a pair of 3-pin male XLR connectors to provide
interconnection for the generator monitor function. If
option "DSP" is installed, the upper right front panel will
also contain a 7-pin male XLR connector to provide
additional DSP related signal interconnections to a
complementary SYS-202 or SYS-302. The lower right front
panel is blank.

SYS-02 Configuration

Dual channel analyzer only system with identical
functionality as the SYS-22. The upper left front panel
contains a pair of female XLR connectors to provide
interconnection to a SYS-20 for the generator monitor
function. The lower left front panel is blank. The lower
right front panel contains five bnc connectors, identical to
the SYS-22 configuration.

SYS-222 Configuration

"System One + DSP". Dual channel generator and analyzer
system including the digital signal processing module for
FFTs and other specialized testing. The front panels are
identical to the SYS-22 configuration except for the lower
left panel which contains six bnc connectors. Blank back panels.

SYS-202 Configuration

Similar to the SYS-222 except the analog generator is
deleted. The upper left front panel contains a pair of 3-pin
female XLR connectors to provide interconnection to a SYS-20
for the generator monitor function plus a 7-pin female XLR
for DSP related signals.

SYS-322 Configuration

"System One Dual Domain". Dual channel generator and
analyzer system including the digital signal processing
module for FFTs and other specialized testing, plus
additional capability and connectors for digital signal
generation and analysis. The lower left front panel contains
a variety of digital audio signal connectors. The lower
right back panel contains parallel digital I/O connectors
plus bnc connectors for the dsp analog I/O. The lower left
back panel contains 3 bnc connectors for the generator
auxiliary signals.

SYS-302 Configuration

Similar to the SYS-322 except the analog generator is
deleted. The upper left front panel contains a pair of 3-pin
female XLR connectors to provide interconnection to a SYS-20
for the generator monitor function plus a 7-pin female XLR
for DSP related signals.
1.3	DIGITAL INTERFACE VERSIONS
The System One hardware can not function without host
computer control. All systems contain one of three different
digital interfaces designated by the letter code "A", "S",
or "G" appended to the system configuration nomenclature.
Thus, for example, the SYS-322A contains the A-version
interface.

NOTE: Early production units with serial numbers 10001 to
10299 did not include a letter suffix in their original
system nomenclature. These units contain the A-version
digital interface.

The digital interface option can also be determined by
observing the connector types and/or the system
configuration decal located on the back chassis panel of
System One. Systems with the A-version interface will have
either one or two 25-pin D-subminiature connectors labeled
with the words "Audio Precision Interface (APIB)". Systems
with the S-version interface will have a pair of 25-pin
D-subminiature connectors (one for APIB and one for RS-232)
plus a DIP switch for baud rate selection. Systems with the
G-version interface will have a single 25-pin D-subminiature
connector for the APIB, IEEE-488 connector, and a DIP switch
for setting the instrument address.

A-Version Interface

The A-version interface is an 8-bit parallel bus optimized
for Audio Precision instrument control. St is referred to as
the "APIB" (Audio Precision Interface Bus) throughout
this manual. See section 1.4 for more information about the
operation of the APIB. Units with the "A" version interface
include a digital interface card that is installed in the
host computer, a digital interconnection cable, and an
extensive software program (SI .EXE) to operate the
hardware, create and run tests and procedures, process data,
and display results.

S-Version Interface

The S-version interface provides both APIB and RS-232
control capability (but not simultaneously). Baud rate is
selected by rear panel accessible DIP switches. Setting all
the baud rate DIP switches to the "up" position activates
the APIB. Please note that the APIB must be used when
servicing or calibrating a System One.

G-Version Interface

The G-version interface provides both APIB and IEEE-488
control capability (but not simultaneously). Address
selection is set by rear panel accessible DIP switches.
Setting all the address DIP switches to the "up" position
activates the APIB. Please note that the APIB must be used
when servicing or calibrating a System One.

This service manual supports all versions and options of the
Audio Precision SYSTEM ONE, the SWR-122 family of switchers,
the DCX-127 multi-function interface accessory, and the
SIA-322 serial interface adapter.

The System One is an obsolete product and has been out of
production for over years. Our stock of replacement parts is
highly limited, and in some cases
nearly depleted. Audio Precision will not be able to provide
repair and adjustment
services beyond December 31, 2007 unless pre-approved by the
Service
Manager.
Please be mindful that if you use this Service Manual to
adjust, service and/or
repair your own System One instrument, Audio Precision does
not support or
warrant its contents and/or use in any way.
Also, any reference to the term “Calibrate” or “Calibration”
within this Service
Manual does not constitute the ISO (International Standards
Organization)
definition of a calibration. The term “Calibrate” or
“Calibration” within this Service
Manual is used only to define “an adjustment to factory
specification.”
