Rear
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. 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.

Side
Side Mounted LEDs - The LEDs give visual indication if RF and / or audio are being received by the QRX.
The LED settings are adjusted in the extended menu. There are three LEDs per group and one group for
each receive channel. The group to the top represents channel one, the group below is channel 2, the
next group is channel 3, and the group on the bottom is channel 4.

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 bar to the right is the -20dBFS mark. A single meter for a receiver indicates a mono signal is being
received. Two meters indicate that a stereo signal is being received.
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 TRX 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.
–(NO SIGNAL) Occurs if the associated transmitter is turned “OFF”

Antenna being used
Indicates the signal is being received by antenna 1 (left antenna connector)
Indicates the signal is being received by antenna 2 (right antenna connector)
RF signal strength
This shows the radio signal strength of the corresponding TRX 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.

Main Menu
Navigating the Main Menu
To enter the main menu - press the MENU key.
To advance to the next menu press the MENU key again.
Exiting the Main Menu
To exit the main menu at any time press and hold the MENU key for 1.5 seconds.
Frequency Display and Select
Single Receiver Mode Dual Receiver Mode
The frequency select menu is where the QRX’s receive frequency is set. This frequency needs to match the
frequency that is set on the corresponding transmitter.
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.
When in dual receive mode the A and B frequency needs to be within 35MHz of each other. If the
frequency difference is more than 35MHz “TOO BIG” or “TOO SMALL” will flash on the screen to warn that
the difference is greater than 35MHz and the frequency will need to be adjusted.
Transmitter Gain Adjust
This menu is only available when transmitter remote control is set to “ON” in the extended menu.
Single Receiver Mode Dual Receiver Mode
When a QRX100 or QRX235, with an IFB option board, is connected to the QRX200 via the serial loop the gain
of the corresponding TRX transmitter can be adjusted via ZaxNet.
The transmitter gain menu will display the incoming audio levels for the transmitter that is being adjusted with
marks at -20dBFS and 0dBFS.
Adjusting the transmitter gain remotely
Press the INC key to increase the transmitters gain. As the gain is increased“+ + +” will be displayed on the
QRX.
Press the DEC key to decrease the transmitters gain. As the gain is decreased “- - -” will be displayed on
the QRX.
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.
Single Receiver Mode Dual Receiver Mode
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.
Modulation Select
Single Receiver Mode Dual Receiver Mode
This menu selects which modulation mode the QRX will receive. Modulation is simply the way a transmitter
“modulates”, or sends, its signal to the QRX. 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.
When in dual receive mode pressing the A/B key will toggle between the A and B format. The >will indicate
the receiver is being adjusted.
Modulation types
XR MONO - Select when extended range modulation (XR) on the TRX transmitter is being used.
We recommend using XR modulation whenever possible.
STEREO - Select when using a TRX900CL - Camera Link, TRXLA2S, or a TRXLT2S stereo transmitter.
MONO - Select when using an older mono transmitter and XR modulation is not available in the software.
EU - Select when using a transmitter that is set up for European broadcast standards.
Test Tone Output
The test tone menu allows the QRX to output tone from the TA5 outputs. This is useful 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)
