General
The TRX900 ( /AA) has an unbalanced microphone input accessed through a 3-pin micro-LEMO connector. You
can use an unbalanced dynamic microphone or a powered lavaliere. It is recommended that you use 3-wire
lavalieres with separate pins for ground, audio and power.
When using a line-level input, an inline pad is required on the standard dynamic microphone input cable (XLR-3 to
3-pin micro-LEMO).
When using a phantom powered microphone with the TRX900 ( /AA), you must use an external 48 VDC power
supply. The TRX700 and TRX992 are the only Zaxcom transmitters that include a 48 VDC phantom power
supply.
NOTE:
Once upon a time, the Denecke 48V power supply could damage the now discontinued Goldline
transmitter’s preamp. This is NOT the case with the TRX900 ( /AA).
