Ease of set-up, with Automatic Frequency Selection and Automatic Transmitter Setup, the PGX14 is the quickest and easiest wireless system to set up. The Audio Reference Companding delivers level dependent companding, compressing the audio signal before transmission, and expanding it after reception to deliver greater than 100dB dynamic range.

A diversity receiver contains two seperate antennaes, each antennae has an independent receiver and the signals are demodulated seperately. The main unit scans these two outputs and seamlessly selects the output with the strongest signal for processing. The result is a wireless system with fewer drop outs, less interference and more reliable reception.

 

Frequency Response (at 8 mm)

Polarity

WH20QTR as a wired microphone:

Positive sound pressure on diaphragm produces positive voltage on tip with respect to sleeve (ground) of microphone output phone plug connector.

WH20QTR, WH20TQG used with Shure Wireless Systems:

1/4-inch Phone Jack Receiver Outputs: Positive sound pressure on diaphragm produces positive voltage on tip of receiver output connector.

3-pin XLR Receiver Outputs: Positive sound pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3 of low-impedance output connector, and on tip of Aux output connector.

WH20XLR as a wired microphone:

Positive sound pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3 of microphone output XLR connector.
