INTRODUCTION:
The MCT-7 Cable Tester is a versatile unit that allows the user to test almost any
pre-made and custom made leads or cables used in a typical audio/visual set up.
Leads fitted with any combination of the following connectors may be checked:
• Male or female XLR
• Speakon (4 pole)
• Stereo or mono 1/4" (6.3 mm) jack
• Stereo or mono 1/8" (3.5 mm) mini jack
• Phono RCA
• BNC
• Midi (180 degrees DIN)
The MCT-7 Cable Tester allows you to test for the following conditions:
• Positive Continuity
• Cross Wiring
• Loose Contact
• Open Circuit
• Leakage Between Wires (up to 10KΩ)
• Short Between Wires
• Short to Ground (female XLR & MIDI)
Please read the following instructions carefully before using the MCT-7 Cable
Tester.
Warning: The leads to be tested must be fully disconnected from any other
equipment or electrical source. Failure to do so could result in electrical shock and
permanent damage to the MCT-7 Cable Tester unit, for which the manufacturer
and suppliers can accept no liability.
The MCT-7 Cable Tester comes fitted with a 9 Volt type battery. Under normal
usage this will allow several hundred hours of operation. We advise that before

Battery “). TEST PROCEDURE: The MCT-7 Cable Tester is simple to operate. A schematic diagram of the connectors and their pin assignments is shown on the front panel of the unit. Light Emitting Diodes (LEDs) give a clear visual representation of the connections. - Page 3 More than one of these five LEDs may illuminate. To determine which position of the Pin Selector Switch corresponds to the pins of the selected connector refer to Table 1 or the diagrams printed on the front panel of the MCT-7 Cable Tester.
- Page 4 • LEAKAGE BETWEEN WIRES, the LEDs of the pins being tested will light, also other LEDs will light with lesser intensity. The intensity with which these other LEDs will light is proportional to the leakage between wires. The MCT-7 Cable Tester will show leakage up to 10KΩ between wires. See Fig. le.
- Page 5 time as the Ground LED, then all those pins have a short to ground. This test only functions for the female XLR and 5 pin DIN (MIDI) connectors. See Fig. 1g. Note: In case of the mini (3.5mm) and 1/4” (6.3mm) jack plugs, there are two versions, mono and stereo.
- Page 6 To change the battery, you will require a Phillips head screwdriver. Remove the four screws located on the bottom of the MCT-7 Cable Tester as shown in Fig. 3. To remove the battery, turn the unit upside-down and carefully remove the base- plate.
