the antenna outputs adds 6dB of gain and is post the bandpass filter.
3. Redundant power input (4 pin Hirose) with LED indicator - The RX-12R will seamlessly switch to the input
with the highest voltage. The LED will illuminate when the RX-12R is receiving externa DC power.
4. Analog out 1 thru 6 (XLR) -These connectors will output analog audio of the A side of the receiver modules.
5. Main AES output (DB25) -This connector will output AES audio of both the A and B receiver for each module.
6. Power switch
7. ZaxNet communication connector (TA5) - This connector is used to interface with an IFB200 to send ZaxNet
remote control commands to the transmitters.
8. USB connector (Standard USB type A cable) - Used to connect the RX-12R with a PC or Mac that is running
Zaxcom wireless monitoring software. Please note the USB connector cannot be used simultaneously with the
RS422 connector.
9. RS422 connector (see wiring diagram) - Used to connect the RX-12R to a Nomad or Oasis Please note the
RS422 connector cannot be used simultaneously with the USB connector.
10. AES and Analog out (DB25) -This connector will output analog audio of the B side of each QRX212 module
outputs (7 thru 12) when the module is set to analog. When the module is set to output AES this connector
will output an AES signal of both the A and B receiver. Please note to output AES the RX-12R will need to have
the optional AES combiner board installed (not currently available).

Inserting the QRX212 Modules
Rear view of the QRX212 Module Up to 6 QRX212 modules slide into the RX-12R.
When inserting the modules make sure the arrows pointing up.

Home Screen Explained
The home screen is divided into six sectors, one sector for each QRX 212 module. Each sector will display the
following information:
Frequency - The current selected frequency will be displayed for each receiver. If the module is in dual
mode both frequencies will be displayed. The A frequency will be on the left and the B receiver will be on
the right. If the frequency is highlighted in red that means the selected frequency is outside the 35MHz
filter. Keep in mind while frequencies outside the range of the 35MHz may still work though performance
will be less than optimal.
Battery level - A battery indicator will display the approximate battery level for each transmitter. A
fully charged battery will display green and then turn red as the battery depletes its charge. The battery
icon will start blinking when the battery has roughly 15 to 30 minutes of charge left. Please note that
when the battery is low the transmitter may not go into record.
Transport status -The transport status of the transmitter’s onboard recorder will be indicated just
above the RF signal strength meter:
STOP - Recording / Playback is stopped
REC - The transmitter is recording
PLAY - The transmitter is playing back
RF Signal Strength - Each module has two RF meters, one for each receiver. The meters show the
amount of RF signal being received. The signal level is visually displayed in the ramp shaped RF meter icon.
As the shading increases from the left to the right the more signal is present. If the icon is shaded red
when the transmitter is powered down that means the receiver is seeing unwanted RF from a source
other than from the corresponding transmitter. If the icon is green the RF is being received from the
corresponding transmitter. Within the icon the actual signal strength, in decibels, is displayed numerically.
Audio Meter - Each module will display audio meter(s) for each signal received. If the module is set to
single mode one large meter will be shown. If the module is set to dual mode two large meters will be
shown. If the module is receiving a signal from a stereo transmitter the large meter will be split in half into
two smaller meters, representing the left and right audio of the transmitter. The meters will show the
audio modulation in dBFS. Within each meter the signal will be represented in green, yellow and red
showing the levels, there is also a peak hold indicator. If a meter has a white X through it that is showing
that the receiver is not receiving a valid signal.
Save Indicator - A pixel on bottom of screen that moves right to left indicates that the RX-12R is saving
a parameter setting to its memory. If the RX-12R is powered down while the pixel is moving the settings
will not be saved and could possibly corrupt the setting memory.

Receiver Configure Menu
The receiver configure menu is where each of the 6 QRX212 receiver modules are
set up from. Once in the receiver configure menu individual receiver modules can
be accessed by pressing the corresponding number key on the numeric keyboard.
In each receiver configuration menu the status of each transmitter will be shown.
This is the same configuration that is in the home screen.
RX Mode
From the RX mode each individual QRX212 module can be set to single or dual mode and can be powered off.
Mode
Single - The QRX212 module is set to receive a single transmitter.
Dual - The QRX212 module is set to receive signal from two transmitters
Power
The power to each QRX212 module can be toggled on and off from the power setting.
Frequency
This is where the frequency of the QRX212 is manually adjusted from. To set the frequency highlight the
receiver that will be adjusted, then rotate the menu encoder knob, or press the desired frequency on the
numeric keypad.
Transmitter Gain
If the RX-12R is connected to an IFB200 the gain for each transmitter can be remotely adjusted from here and
will be sent over ZaxNet to the transmitters.
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 corresponding transmitter for the remote frequency and gain commands to 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. Each module can be set to
output audio as either an analog signal or an AES signal. This setting will determine what is outputted on the
bottom DB25 connector “AES AND ANALOG OUT”. If this is set to analog the DB25 will output the b side of each
receiver QRX212 receiver module. If this is set to AES, when used with the optional combiner board (not
currently available) the DB25 will mirror the top DB25 connector.
Tone
Each QRX212 module has its own tone generator. 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 RX-12R 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 RX-12R 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.
