How do I connect a Sennheiser MKE2 to a Shure bodypack?FAQ #321
Question:How do I connect a Sennheiser MKE2 to the TA4 connector on a Shure bodypack?
DISCLAIMER: This bulletin was written with information provided by Sennheiser. Shure is not responsible for damage caused to a Sennheiser microphone if this circuit proves incorrect.
There are two methods to wire a Sennheiser MKE2 to a Shure bodypack.
Method 1: -R and -P style models
To make this modification it is necessary to remove the connector or preamp attached to the microphone cable. This will require disassembling the connector or preamp and unsoldering the attached cable or simply cutting off the cable at the strain relief. Once this is accomplished, the following color codes configuration can be applied to equip the exposed cable with a Switchcraft TA4F connector for mating with the Shure wireless transmitter.
Pin 3 and Pin 4
Method 2: -3, -2, -5, -2R, & -4, all MKE2 GOLD Models
Per Sennheiser's Service Department (860-434-9190 ext. 151) any Sennheiser MKE2 microphone that is factory supplied without a connector (pigtailed cable) can be connected to a Shure transmitter using the following diagram. This wiring scheme provides an output level that is 10 to 14 dB greater than the typical wiring scheme.
Note: This circuit may not work if the MKE2 is supplied with a connector by Sennheiser. MKE2 units with factory supplied connectors may be wired differently within the capsule.
The following color codes configuration can be applied to equip the pigtailed cable with a Switchcraft TA4F connector for mating with the Shure wireless transmitter.
R1 = 8.2k Ohms, 1/8 Watt
The resistor should fit inside of the TA4F.
The jumper is required between Pin 3 and Pin 4 to set the correct input impedance (20k ohms).
If there is no short circuit between the blue wire and shield, please use the first pin configuration, otherwise the second.
There are -3 models which will not work properly with the second pin configuration also. This depends upon the original mic condition, with or without Sennheiser connector.
MKE2 Gold models will work in either configuration with any body pack and with the RK100PK but not with the RPM626. To get them to work with a RPM626 use the second configuration.
The mating connector for the Shure wireless transmitters is a Switchcraft TA4F. This connector is available from the Shure Service Department at 800-516-2525 or 847-600-8699 as part number WA330.
The connector can also be purchased from Mouser Electronics at 800-346-6873.
PIN 1 = cable shield / audio return / bias return
PIN 2 = +5V DC Bias
PIN 3 = audio input for dynamic mics or instruments
PIN 4 = 20K Ohms resistor to ground jumpered to pin 3 for condenser mics
