Front Panel
1. QRX212 Modules - The RX-12R can accommodate up to 6 modules.
2. Numeric keypad
3. Back Key
4. Daylight Readable Color LCD Screen
5. Headphone out (3.5mm TRS) - The headphone output can be used to monitor the A side of each
module. To select the module to monitor press the numeric key that corresponds to the module
number.
6. Enter Key
7. Menu Encoder Knob - Press the menu knob to access the RX-12R menus. Rotate and press to adjust

1. RF In Antenna - A and B (50 Ohm BNC)
2. RF Out Antenna - A and B (50 Ohm BNC) - The antenna out is used to feed additional receivers. Please note
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).

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.
