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 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.
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.
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)
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 Adjust
The 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.
Please note that when in dual receive mode the A and B frequencies 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.
When a QRX100 or QRX235 with an IFB option board is connected via the serial loop, the gain of the corresponding
transmitter can be remotely adjusted from this menu. 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.
