Unit Code
This is where the ZaxNet unit code for each module is set. The unit code on each QRX212 receiver must
match the unit code set in the TRX transmitter so that remote frequency and gain commands can be sent to
the proper transmitter. Each receiver and transmitter pair must have its own unique unit code. The unit code
number can be set to any number between 1 and 99.
Output Type
The output type sets what audio signal the individual QRX212 module will output via the TA5 connector. Each
module can be set to output the audio as either an analog signal or an AES signal.
AES Mode
There are two AES output pairs per QRX212 module. When receiving two mono transmitter signals on a
single QRX212 module the two audio channels will appear on one AES pair by choosing the AES swapped
mode
Tone
Each QRX212 module has its own tone oscillator. Turning tone on will output tone from the TA5 connector
at -20dBFS allowing for the levels to be calibrated at the mixer or recorder.
Center Frequency Set
The RX12 has a 35MHz tracking front end filter that eliminates unwanted stray RF which can desensitize the
receiver and result in poor performance.
The center frequency is the middle frequency of the 35MHz window.
After deciding on the 35MHz operating range the center frequency should be set to the middle of that range.
Therefore the best performance of the RX12 will be frequencies chosen 17.5MHz above and 17.5MHz below
the center frequency. Please note that this is a global setting for all QRX212 modules meaning that that the
35MHz window will be the same for all modules.
To adjust the center filter rotate the menu encoder knob to the desired frequency, or manually enter the
desired frequency using the numeric keypad.
