Introduction

Thank you for purchasing the Galaxy Audio JIB/CT Cable Tester.
The CT is designed to test a wide variety of commonly used audio
cables and quickly answer the question, “Is this cable good or bad?”
A unique computer controlled circuit tests the cable 200 times per
second, which allows the CT to detect and display intermittent
problems that other cable testers fail to catch. The CT control panel
simply consists of a rotary switch, one Green LED, and one Red
LED. A quick reference chart is located on the bottom of the unit.

Operation

1. Battery Installation: Switch to OFF position. Remove the Battery
Drawer and install a 9-volt alkaline battery, being careful to not
pinch any of the wires when reinstalling the Drawer. Due to the low
power consumption design and the Auto Shutoff feature, the battery
life of a standard 9V alkaline should be over 100 hours. The Auto
Shutoff feature switches off the CT after approximately 5 minutes
of inactivity. To reset the CT after Auto Shutoff, simply rotate the
switch to the “Off” position and then back to your previous setting.
If the Red LED becomes too dim to see, replace the battery with a
fresh 9V alkaline.

2. Connections: Plug one end of the cable to be tested into the
appropriate connector on the “A” side of the CT, and the other end
of the cable into the “B” side. All of the connectors on the “A” side
are duplicated on the “B” side except for the XLR jacks, where the
“A” side has a Female XLR and the “B” side has a Male XLR.

CAUTION: Do not connect the CT to any audio device or system.
Damage may result to the CT and/or the audio device.

3. Select Test: Rotate the switch to select the number of conductors
within the cable.
NOTE: For accurate results it is necessary to select the correct
number of conductors within the cable under test. If in doubt, you
may want to remove one of the connector covers to count the
conductors emerging from the cable.

The following chart lists the number of conductors found in
commonly used audio cables. When speaking of 1/4” or 1/8”
connectors, the terminology TRS (Tip, Ring, Sleeve) is used to
describe the conductors as they appear on the plugs. A Mono cable
(2 conductor) would use only the Tip and Sleeve (TS), while a
Stereo or balanced cable (3 conductor) would use all three Tip,
Ring, and Sleeve (TRS).
