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.

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.

AES Digital out of TA5
The TA-5 connectors can also be used to output AES digital audio. Each TA5 will output a stereo pair on pins
1, 2 and 3 with pin 1 being ground.
When receiving audio from a mono transmitter the QRX will output the same audio on both pairs of the
TA5. When receiving audio from a stereo transmitter the QRX can output both signals on a single TA5.
IMPORTANT: While sending digital audio, it is necessary that the unit on the other end (recorder, mixer, etc.)
have digital inputs with sample rate convertors, as there is no way to synchronize the output data with the
recorder’s digital input.
