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.

Receiver
The QRX has two individual receivers the A (left receiver) and the B (right receiver).
Audio level
Indicates the incoming audio level for each receiver, the meter extends from the left to the right. The vertical
bars to the right are the -20dBFS and -10dBFS marks.
Transmitter’s battery level
The battery diagram displays the transmitter’s battery level. The battery type being used in the transmitter needs
to be set in the transmitters extended menu. The battery symbol will start to blink just before transmitter shuts
down.
Transmitter’s record status
• S (STOP) The transmitter is stopped.
• R (REC) The transmitter is recording.
• P (PLAY) The transmitter is playing back.
RF signal strength
This shows the radio signal strength of the corresponding transmitter. The RF signal is depicted as a staircase
pattern with the lowest step (low signal strength) on the left and building up as it progresses to the right (higher
signal strength). When more stairs are showing the stronger the signal is.
Receiving antenna
Indicates the signal is being received by antenna 1 (left antenna connector)
Indicates the signal is being received by antenna 2 (right antenna connector)

Exiting the Main Menu
• To exit the main menu at any time press and hold the MENU key for 1.5 seconds.
Frequency Adjust
The frequency select menu is where the QRX235 receive frequencies are set. These frequencies need to match
the frequencies that are set on the corresponding transmitters.
Adjusting the receive frequency of the QRX
• Press the INC key and DEC key to adjust the frequency.
• In dual receive mode pressing the A/B key will toggle between the A and B receiver.
The > will indicate the receiver being adjusted.
Transmitter Gain Adjust
This menu is only available when transmitter remote control is set to “ON” in the extended menu.
The transmitter gain menu allows for the input gain on the transmitter to be remotely adjusted when the QRX235
has a QIFB option board installed the gain of the corresponding transmitters. The transmitter gain menu will
display the gain level and an audio meter with a -20dBFS and -10dBFS mark on the right.
Adjusting the transmitter gain remotely
• Press the INC key to increase the transmitters gain. As the gain is increased“+ + +” will replace the gain level.
• Press the DEC key to decrease the transmitters gain. As the gain is decreased “- - -” will replace the gain level.
• When in dual mode pressing the A/B key will toggle between the two transmitters.

Unit Code Select
This menu is only available when transmitter remote control is set to “ON” in the extended menu.
This menu sets the unit code that will correspond to the transmitter that is being controlled. The unit code is a
unique number used to identify a transmitter within a particular group. This allows individual transmitters that
are within the same group to be independently controlled. Unit codes can be any number from 1 to 200.
Test Tone Output
From the tone menu a 1K test tone can be enabled. That tone will be outputted from the TA5 connectors.
This is used to set levels and check routing.
Pressing the INC and DEC key will cycle through the different tone settings.
• OFF - No tone is being outputted.
• -20dBFS -Tone is simultaneously sent to all 4 outputs at -20dBFS.
• CHAN-ID -Tone is sequentially sent to each channel one at a time at -20dBFS.
• +0dBFS - Simultaneously sends tone to all 4 channels at 0dBFS (full scale)

Frequency Scan
PRESS TO SCAN
The frequency scan menu is where the QRX can scan and search for a clear frequency. After the scan is
complete a graphical display of the RF that is present, in that specified range will be shown and the QRX235
will suggest a clear frequency. That frequency can be accepted by pressing the INC key. Or press the DEC key
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.
At that point:
• Press the INC key to accept the frequency.
• Press the A/B key or the DEC key to suggest another frequency.
Dual mode scanning
• Turn on the first transmitter and set it to the chosen frequency.
• Press the A/B key to scan the B receiver.
• Press the INC key to initiate a scan.
• Select the second frequency the same way the first frequency was
selected.

Modulation Select
RX FMT: ZHD96
From this menu the modulation mode is selected. Modulation is simply the way a transmitter “modulates”, or
sends, its signal to the QRX235. This setting needs to match the modulation mode that the corresponding
transmitter is set to - if the two setting do not match the QRX will not be able to receive and decode the signal
from the transmitter. Please note the QRX will need to be rebooted after a change is made to the modulation.

RX MODE:
SINGLE
• SINGLE - This configures the QRX to operate as a single receiver. In single mode the QRX can receive one audio
channel from one transmitter.
• DUAL - This configures the QRX to operate as two independent receivers. In dual mode the QRX can receive
audio from two transmitters.

• SPLIT / NORMAL - The signal from each transmitter will be outputted on individual TA5 connectors.
Transmitter 1 will be outputted on TA5 1 and transmitter 2 will be outputted on TA5 2.
• COMBINED / SWAP - The signal from each transmitter will be combined on a single TA5 connector.
IFB Output Mix
IFB OUTPUT MIX:
The IFB output mix selects which receive audio channels will be broadcast via ZaxNet when the QIFB option is
installed and set to transmit. Any combination of the 4 receive channels can be selected. The selected channels
will be broadcast when “QRX” is selected in the IFB input mix menu. Please note that this setting is only for
broadcasting the audio received from the UHF signal - not the audio inputted via the IFB in.
IFB Enable
IFB ENABLE:
IFB enable turns on the QIFB option board - when installed. Please note that the IFB option board needs to be
enabled for the QRX235 to send or receive ZaxNet commands.
