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.
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.

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 this menu 1K 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
The frequency scan menu is where the QRX can scan the specified frequency range to search for a clear
frequency. After a scan a graphical display of the RF that is present, in that specified range, will be shown.
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
In dual mode the two operating frequencies must be within 35MHz of
each other. Pressing the INC key will scan the full chosen scan range
(scan range is set in the next menu) and recommend a frequency from
the entire range. If a second frequency is being chosen to work with a
previous chosen frequency, press the DEC key to limit the scan to a
70MHz window which is 35MHz above and 35MHz below the other
selected frequency. After a scan is triggered, by either pressing INC or
DEC key, the QRX will scan and suggest a frequency. After the scan is
completed that frequency can be accepted or rejected the same way as in single mode. If an exclamation point
appears after the suggested frequency that is a warning that the shown frequency is more than 35MHz away
from the other frequency. That frequency can be selected provided a new frequency that is within 35MHz of
this frequency will be selected for the other receiver. After the first scan turn on the first transmitter and set it
to the chosen frequency, this way when the scan is performed for the second transmitter the QRX will not
select the same, or adjacent, frequency. To toggle between scanning RXA and RXB press the A/B key.
