Optional XLR Compatibility
To connect the MX153 earset to an XLR microphone input, use the RK100PK pre-
amplifier (see Optional Accessories).
Phantom Power
The RK100PK preamplifier requires phantom power and performs best with a 48
Vdc supply (IEC-61938). However, it will operate with slightly decreased head-
room and sensitivity with supplies as low as 11 Vdc.
Most modern mixers provide phantom power. You must use a balanced micro-
phone cable: XLR-to-XLR or XLR-to-TRS.
RFI Filtering
This microphone features CommShield
®
Technology for superior RF filtering. For
best results in hostile RF environments, always use the RK100PK preamp (see
Optional Accessories).
