To make such a cable, first acquire the following components:
(1) Female XLR cable connector
(1) Male XLR cable connector
(1) 1/4" TRS cable connector
A suitable length of light gauge unbalanced microphone cable
A short piece of 22 gauge bus wire
Then follow these steps to assemble the cable:
1.
Cut two lengths of audio cable suitable to reach from the 1176LN to the insert point on your
mixer. Light gauge cable should be used in order to allow the two cables to comfortably fit
inside a TRS jack. Use a short piece of bus wire to tie pins 1 (cold) and 3 (ground) together on
each XLR connector. Only solder pin 3, as you will also need to solder an audio lead into pin 1.
2. On both XLR connectors, solder the hot (white) lead into pin 2, and solder the cold (black) lead
into pin 1, as well as the other end of the bus wire (as described in the previous step).
3. Solder the hot (white) lead from the cable connected to the male XLR to the tip connection
point of the TRS jack. Solder the hot (white) lead from the cable connected to the female XLR
to the ring connection point of the TRS jack. As shown in the photograph below, combine the
cold lead and the shielding together at the ground point.
4.
Your finished cable should look like the photograph below. Be sure to check continuity with a
voltmeter or test light before use, to ensure proper grounding and signal flow.
