Hirose Wiring for Sony Bodypacks
Notes:
When using TwinPlex mics with Sony Hirose 4pin bodypacks, Shure recommends purchasing Shure –MTQG versions
and not –NC versions. This facilitates an easier termination due to the lack of circuitry required in Shure 3wire/MTQG
TA4F products.
Due to the thin cable on TwinPlex and the large boot on Hirose connectors, heat shrink may be required to build up the ca
ble under the boot where the crimp connection is made and where the cable exits the boot
The TwinPlex Microdot (-MDOT) version can be used with 4-pin Hirose adapters from DPA (DPA part # DAD6008)
