1. DC Power Input - The QRX uses a Switchcraft 761K connector.
2. Audio out connectors (2) - TA5M
These connectors will output the audio from the QRX. The same connectors can be used to output either
analog audio or AES audio. The audio assignments for the TA5 connectors are set in the extended menu.
3. IFB Audio - 3.5mm TRS (available with the QIFB option)
•When ZaxNet is set to transmit (TX) this connector will accept external audio for IFB transmission.
•When ZaxNet is set to receive (RX) this connector will output the ZaxNet received audio.
4. Time Code In/ Out - 3.5mm TRS (available with the QIFB option).
This connector will input or output time code depending on how the cable is wired. Please see the wiring
diagram section of this manual.
5. Serial Loop -The USB style connectors on the back of the QRX allow multiple QRXs to share a single
common QIFB option. For example one master QRX with a QIFB option board can be connected to 3 QRXs
with no option boards. The QRXs without option boards will behave as if they have an IFB option board
and will send remote control commands over the serial link to the master QRX.
Please note the USB connectors are NOT generic USB connectors that can be used as a connection to any
computer. These are used to exchange RS-422/RS-485 commands and a special cable is required to do this
please see the wiring diagram section of this manual for more information.

to skip the first chosen frequency and have the QRX235 suggest another frequency.
Single mode scanning
•Turn off the transmitter.
•Press the INC key to initiate a scan.
•As the block is being scanned, the frequency being examined is
displayed on the bottom half of the screen and a graphic map of the
RF that is found will be displayed with a vertical line extending up from
the baseline. The length of the line indicates the level or strength of
the found RF at that frequency.
Selecting a frequency
When the scan is complete a suggested frequency will be shown and a
vertical blinking line will be drawn on the display.

QRX Software Update
The software update menu is where a firmware update for the QRX is initiated from. After the INC key is pressed
the QRX will wait for firmware to be sent from a TRX transmitter. When the QRX receives the firmware the
update process will automatically begin. Please note the QRX needs to be set to mono modulation and in single
mode to update the firmware. Please see the firmware section in the back of this manual for additional
information on updating the QRX.
AES Recognize
The AES recognize is used for some Sony F5 or F55 cameras that cannot recognize the AES signal from the QRX.
•OFF - The QRX will output a normal AES signal.
•ON: AB KEY - This setting will send a special signal to the AES out, when the A/B key is pressed. This will allow
the Sony camera to recognize and lock to the AES signal from the QRX. This is the recommended setting.
•ON: ALWAYS - The QRX will constantly send a special recognize signal via the AES out.
AES Output Sample Rate Adjust
This menu adjusts the AES output sample rate.

This menu sets the action of the bottom LED in each group (total of 4 groups).
The side mount LEDs were designed to give visual confirmation that audio is being received at the QRX. This
menu gives the option to display that a valid RF signal is getting to the QRX even if no audio is being sent.
•OFF - The bottom LED will only display the audio modulation and the blue LED is disabled.
•BLUE FULL TIME - Turns the bottom LED blue for each channel that is receiving a valid RF signal. When the
audio has gotten to the point of displaying a level for that channel, the bottom LED will continue to show blue
but with a tint of the appropriate modulation color of that channel’s LEDs.
•BLUE PART TIME - Turns the bottom LED blue for each channel that is receiving a valid RF signal. Once the
audio is received, the blue is replaced with the appropriate modulation color for that channel.
Encryption Code Set
The encryption menu is where the encryption is turned on and the code is set. The encryption code needs to
match the encryption code of the associated transmitters. If an encryption code is set on the transmitter the
transmitted audio will be encrypted and can only be listened to if the QRX has the same matching encryption
code entered. When the codes do not match, all that will be heard is white-noise.
These two sets of numbers are formed into a single six-digit encryption code which provides a total of
16,777,216 possible combinations. For non-encrypted operations all six numbers should be set to 0.
Adjusting the encryption code
1. Press the A/B key to advance to the next character.

•QRX ONLY - QRX mix only (set in the IFB output mix menu).
•RIGHT - The right input of the IFB audio connector only.
•LEFT - The left input of the IFB audio connector only.
•L + R - Sums the left and right IFB audio inputs.
•L - R - Sums the difference of the left and right IFB audio inputs. This effectively makes the IFB audio input a
balance connection.
Please note that ZaxNet transmitted audio is mono so all audio selected will be summed to mono.

Remote Power Mode
This menu is only available when IFB Mode is set to TX (transmit)
The remote power mode menu allows for the RF power setting of the transmitters to be adjusted.
The transmitters have three selectable power settings:
•NORMAL - The transmitters are at full power.
•WAKE - If a transmitter is set to REMOTE STANDBY it will power up to a non-transmitting low power mode
that will use approximately 25% of the power of normal operations. A wake command will bring that
transmitter to full power.
To use wake mode set the transmitters BOOT UP MODE to REMOTE STANDBY. Then when the transmitter
powers up, it will remain in standby mode until it receives the wake command to bring it to full power. Once
the transmitter is awoken the only way for it to go back into standby mode is by power cycling the
transmitter.
•LOW 2 - Low 2 disables the RF power amplifier, RF board and microphone pre-amp on the transmitter. In
LOW 2 mode the transmitter will save approximately 50% of the power of normal operations. A transmitter
can be put into or taken out of LOW 2 as often as desired when selected in this menu.
Settings
0: POWER=ON - Normal operation - the transmitter will be fully powered ON.
1: POWER=ON - Normal operation (same as 0) filler to prevent accidental power setting adjustment.
2: POWER=ON - Normal operation (same as 0) filler to prevent accidental power setting adjustment.
3: POWER=ON - Normal operation (same as 0) filler to prevent accidental power setting adjustment.
4: POWER=ON - Normal operation (same as 0) filler to prevent accidental power setting adjustment.
5: POWER=WAKE - Selected to wake a transmitter to full power mode from remote standby mode.
6: POWER=LOW2 - Selected to put a transmitter into and out of low power mode. A transmitter can come
in and out of LOW 2 mode as needed. When in LOW 2 mode “LOW 2” will be displayed on the transmitter’s
home screen. Please note LOW 2 will not disable recording but audio will be muted since the preamp is
disabled. Once the transmitter’s power is set to Low 2 the QRX235 can be powered down. Then when the
QRX235 is powered up all transmitters being controlled will automatically come up to full power since the
QRX235 will always boot up to the 0 Power setting. Please note if the transmitter is not in range of the
ZaxNet signal, the power setting command will have to be repeated once the transmitter comes back into
range.
