1. IFB Audio - (available with the QIFB option) 3.5mm TRS.
•This connector will accept external audio for IFB transmission when the QIFB is in transmit mode.
•This connector will output ZaxNet audio when the QIFB is in receive mode.
2. DC Power Input - The QRX uses a Switchcraft 761K connector.
3. 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.
4. Time Code In/Out - (available with the QIFB option) 3.5mm TRS.
This connector will input or output time code depending on how the connector is wired.
5. Serial Loop-The USB style connectors on the back of the QRX will 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.
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.

The side mount LEDs were designed to give you a visual confirmation that audio is being received at the
QRX. This menu gives you the option to display that a valid RF signal is getting to the QRX even if no
audio is being sent.
•OFF - The bottom LED will only display the audio modulation and the blue LED is disabled.
•BLUE FULL TIME - Turns the bottom LED blue for each channel that is receiving a valid RF signal. When
the audio has gotten to the point of displaying a level for that channel, the bottom LED will continue
to show blue but with a tint of the appropriate modulation color of that channel’s LEDs.
•BLUE PART TIME - Turns the bottom LED blue for each channel that is receiving a valid RF signal. Once
the audio level has gotten to the point of displaying a level for that channel, the blue color is replaced
with the appropriate modulation color of that channels LEDs.
Encryption Code Set
This menu sets the encryption code on the QRX. This code needs to match the encryption code of the
associated transmitters.
If you set an encryption code on the transmitter the transmitted audio will be encrypted and can
only be listened to if the QRX has the same matching encryption code entered. When the codes do
not match, all that will be heard is white-noise.
These two sets of numbers are formed into a single six-digit encryption code which provides a total
of 16,777,216 possible combinations.
To adjust the encryption code
1. Press the A/B key to advance to the next character.
2. To change the designated character, press the INC or DEC key.
3. To exit this page, press and hold the MENU key.
NOTE: Both of these codes should always be set to 000 for normal un-encrypted operation.

This menu sets what audio will be broadcast via ZaxNet back to you for confidence monitoring and to
ERX receivers.
You can choose to broadcast the UHF audio that the QRX receives, audio that is inputted via the IFB
audio in connector, or any combination on the two.
The QRX MIX audio is set in the IFB Output Mix menu located in the extended menu.
•RIGHT + QRX - Sums the right IFB audio input with the QRX mix.
•LEFT + QRX - Sums the left IFB audio input with the QRX mix.
•L + R + QRX - Sums both IFB audio inputs and the QRX mix.
•L - R + QRX - Sums the difference of the left and right IFB audio inputs plus the QRX mix.
•QRX ONLY - QRX mix only.
•RIGHT - The right input of the IFB audio connector only.
•LEFT - The left input of the IFB audio connector only.
•L + R - Sums the left and right IFB audio inputs.
•L - R - Sums the difference of the left and right IFB audio inputs. This effectively makes the IFB audio
input a balance connection.
Remote Power Mode
This menu is only available when IFB Mode is set to TX
This menu allows you to remotely adjust the power setting of the TRX transmitters.
The TRX transmitter has three power settings
•NORMAL - The transmitters are at full transmitting power at all times.
•WAKE - When you select “WAKE” in this menu the TRX transmitter will go to full power.
If the TRX is set to REMOTE STANDBY it will power up to a non-transmitting super low power
mode. A TRX in this state will use approximately 25% of the power of full operations. This may be
helpful if you have to mic someone who will not be on set for a while and you want to conserve
battery life.
To use this feature you would set the TRX BOOT UP MODE to REMOTE STANDBY. When the
transmitter is in REMOTE STANDBY the TRX, when powered up, will remain in standby mode until
it receives the wake command to wake it. Once the TRX is awoken from this power mode the only
way the TRX will go back into this mode is with a power cycle.
•LOW 2-This setting is used to put the TRX transmitter into Low 2 mode. Low 2 disables the RF
power amplifier, RF board and mic pre-amp. The TRX will run on approximately 50% of the power
of normal operations which will extend the battery life of the transmitter. The TRX can be put into
or taken out of this mode when “LOW 2” is selected in this menu. The QIFB can put the
transmitter into, and out of, Low 2 mode as often as you like.

•6: POWER=LOW2 – This setting can put the TRX transmitter into and out of a low power setting.
You can come in and out of LOW 2 mode as needed. When you are in LOW 2 mode “LOW 2” will be
displayed on the TRX’s home screen. Note LOW 2 will not disable recording but it will be muted.
Once you have reduced the TRX power to Low 2 you can power down your QRX. Once you power up
the QRX all TRX’s being controlled will automatically come up to full power since after a power cycle
the QRX will boot up to the 0 Power setting.
Time Code Set
