Test Cables
Note: In order to be able to properly test the T1 ToneMatch Audio Engine, you will need to make
up a few test cables.
1. Balanced XLR Microphone Input Test Cable
Parts needed:
1 - XLR male connector
1 - Dual banana jack
Shielded stereo cable, 6 feet
This cable is used to test the channel 1, 2 and 3 microphone inputs on the T1. These input jacks
are dual purpose jacks that will accept either XLR or 1/4” TRS phono jack balanced inputs.
• Connect the dual banana jack positive (+) connection to pin 2 of the XLR jack.
• Connect the dual banana jack negative (-) connection to pin 3 of the XLR jack.
• Connect the cable shield to pin 1 of the XLR jack.
2. Balanced 1/4” Test Cable
Parts needed:
1 - Tip/Ring/Sleeve (TRS) 1/4” phono jack
1 - Dual banana jack
Shielded stereo cable, 6 feet
This cable is used to test the channel 1, 2, 3 and 4/5 line inputs and the preamp, master and
aux outputs.
• Connect the TIP of the phono jack to one of the shielded twisted pair wires.
• Connect the RING of the phono jack to the other wire in the shielded twisted pair.
• Use an ohmmeter to determine which wire is connected to the TIP of the phono jack.
Connect this wire to the positive (+) connection on the dual banana jack.
• Connect the wire connected to the RING of the phono jack to the banana jack negative (-)
connection. The SLEEVE portion of the jack is the common ground where the cable’s shield
should be connected. Connect the shield at the phono jack end only.
