Encrypted Transmission Function 

(ENCRYPTION)

Set the parameters for the encrypted transmission function.

SECURE KEY:

 Sets the encryption key method.

PASSWORD:

 Sets the password method.

OFF: 

The encrypted transmission function is not used.

For details, see “Using the Encrypted Transmission 
Function” on page 21.

Setting the Audio Codec Mode 
(CODEC MODE)

Set the audio codec mode.
If there is a transmitter paired with this receiver, the audio 
codec mode of the transmitter is also switched at the same 
time.

MODE1:

 This audio codec mode is compatible with the 

first generation DWX series. When the reception 
frequency is set to Type B, MODE1 is selected 
automatically.

MODE2:

 This audio codec mode reduces the delay time. 

Audio quality is also improved compared with MODE1. 
We recommend using this mode under normal 
circumstances.

MODE3:

 This audio codec mode prioritizes stable 

transmission performance. Additional signal processing is 
used to suppress noise and audio interruptions caused by 
unexpected interference, resulting in more reliable 
transmission.

Audio delay time when transmitting and 
receiving

The audio delay time matched on the transmitter side and 
receiver side for each mode is as follows.

Analog output
MODE1:

 3.4 ms

MODE2:

 1.5 ms

MODE3:

 4.0 ms

Digital output
MODE1:

 3.4 ms

MODE2:

 2.5 ms

MODE3:

 4.9 ms

For details, see “Setting the Audio Codec Mode” on 
page 22.

Setting Analog Audio Output Level 

(BAL OUT LEVEL)

Selects analog audio output level for the ANALOG OUT 
1/2 connectors.

MIC

: Selects the microphone level (reference level: 

–58 dBu).

LINE

: Select the line level (reference level: –12 dBu).

Ground Lift Function 

(GROUND LIFT)

When LIFT is selected, pin 1 (GROUND) of the XLR 
connector is lifted from the chassis grounding to prevent 
hum, buzz, and other noise caused by ground loops.

GROUND

: Connects pin 1 (GROUND) of the XLR 

connector to the chassis grounding.

LIFT

: Lifts pin 1 (GROUND) of the XLR connector from 

the chassis grounding.

Select LIFT only in environments where hum, buzz, and 
other noise occur. Selecting it may make the unit more 
susceptible to exogenous noise.

Audio Output Setting 

(AF OUTPUT)

Control audio output (MUTING/UNMUTING) for the 
receiver channels. This setting applies to the ANALOG 
OUT 1/2 connectors, and DIGITAL OUT 1/2/3/4 
connectors. This setting does not apply to the audio output 
for the headphone monitor.

UNMUTING:

 Disable audio output muting on the receiver 

channel.

MUTING:

 Enable audio output muting on the receiver 

channel. While muting is enabled, the transmitter name 
display area on the top display alternates between 
displaying “MUTING” and the transmitter name.
