MODEL A96F LINE MATCHING TRANSFORMER
This transformer connects microphones with an XLR-type connector
to the 3.5 mm (1/8 in.) inputs found on camcorders and other recording
devices. It increases the signal level from the microphone, provides a
balanced input, and prevents distortion due to the d.c. bias typically
found in camcorder microphone inputs.
IMPEDANCE SELECTION
The A96F can be modified for microphones rated at 150 W. This
modification is only necessary if the output level from the A96F is
insufficient for your recording device. Use the following steps:
1. Access the wiring in the XLR plug element of the A96F by loosen-
ing the screw and sliding the plug from the case.
2. Unsolder the RED lead from pin 2. Insulate the bare wire at the end
of the lead with the insulator from the YELLOW lead.
3. Solder the YELLOW lead to pin 2.
4. Rotate the plug element three turns to twist the leads and replace
the element in the housing. Replace the screw.

TROUBLESHOOTING
1. Unscrew the housing from the miniature plug on the
A96F to expose the wires inside the connector.
2. Use wire clippers to cut and remove the wire between the tip
and ring leads (see figure below). Make sure to remove the
wire completely from between the leads so that there is no
contact between the tip and ring.
3. Reassemble the plug.
If the microphone still does not work, contact Shure Application
Engineering at 1-800-516-2525. Please have the camcorder user's
guide available.
