IMPORTANT -
On receipt of these units, check for visible damage. Any claims for transit
damage must be made within 14 days of receipt to be covered by warranty. It is important
that all repairs are carried out by an authorised BSS agent, as evidence of internal
tampering may invalidate this warranty.
TO OBTAIN THE BEST POSSIBLE RESULTS, THIS MANUAL MUST BE READ PRIOR
TO USE.
INTRODUCTION
The AR130 test system is a specialist piece of equipment for checking the phase
correctness between input and output of most electrical, electronic or electro-mechanical
units. This unit must have at least one two-wire port, which need not be balanced. Such
examples are multiway connecting cables, equipment racks, sound mixing consoles,
microphones and loudspeakers.
The test system consists of a SOURCE, the AR13OS, and a DETECTOR, the AR130D.
The source provides an encoded test tone, and is normally connected to the equipment
input. The detector dictates the phase, either in or out, between input and output, and is
connected to the output of this equipment. For units which are frequency dependant,
provision is made to adjust the test tone frequency. Also available is a foam lined carrying
case to house the phase check set, two XLR balanced to unbalanced converters and two
spare batteries.
1.0 GENERAL
1.1
Batteries
Ensure unit is switched off before fitting two 9 volt, PP3 sized batteries, and check carefully
for correct orientation. It is strongly recommended that alkaline type cells are used, as
these will give extended life, and also provide enough power for the AR130S to drive an 8
ohm loudspeaker directly. On switching on the source, the range LED will illuminate, and
the step switch will allow selection of the frequency range. For the detector, only the ON
LED will illuminate. If the battery low LED illuminates check both batteries and their
connections.
1.2 Checking Operation
It is possible to check the correct operation of the system by connecting the source and
detector directly together with a standard balanced lead. The detector's green phase LED
will illuminate when the source output switch in the N position, and the red one when this
switch in the R position. This action can also be checked on all four frequency ranges, and
a range of source output level.
1.3 Connection
AR130: Before connection to your equipment, check the connector wiring diagram for
compatibility. If used on an unbalanced system, the supplied XLR converter can be used to
provide the necessary rewiring. AR130D: this has a universal input wiring configuration,
enabling all forms of wiring to be accommodated for without the need to use converters.
