Audio Setup Menu
Audio Level
Set audio output level with the level control. The mute 
button is a toggle used to mute or unmute the audio 
output. The TONE check box is used to generate a 
1 kHz test tone at the audio output.
Audio Polarity
Select normal or inverted polarity for each 
audio channel.
Smart Noise Reduction
Three levels of noise reduction are available: High, 
Normal and Off.
NOTE: Smart Noise Reduction is only available for 
digital hybrid compatibility modes.
Compatibility Modes
Multiple compatibility modes are available to match vari-
ous transmitter types. 
The following modes are available:
•  D2: Encrypted digital wireless channel
• DUET CH1: To receive Channel One audio from a 
Duet transmitter
• DUET CH2: To receive Channel Two audio from a 
Duet transmitter
• NA HYB: Legacy digital hybrid mode
• EU HYB: Used only for certain digital hybrid trans-
mitters marketed in the European Union
• NU HYB: Digital hybrid mode for current Lectroson-
ics transmitters
• JA HYB: Used only for certain digital hybrid trans-
mitters marketed in Japan
Talkback Setup
Talkback is a special function that re-directs the audio 
output of the transmitter in use to a different receiver 
output when talkback is selected on the transmitter. The 
normal use is to provide a “comm” channel so the per-
son using the transmitter can have a direct line to the 
crew or production staff. When selected, the audio will 
appear at the designated talkback channel rather than 
the channel used for program audio.
IR Sync & Encryption Menu
Encryption Key Management
The DSQD has three options for encryption keys: 
 • Standard: This is the highest level of security. 
The encryption keys are unique to the DSQD and 
there are only 256 key instances available to be 
transferred to a transmitter. The receiver tracks the 
number of keys generated and the number of times 
each key is transferred. Once a Standard key has 
been transferred 256 times, you will be alerted that 
a new key must be created.
 • Shared: There are an unlimited number of 
shared keys available. Once generated by the 
DSQD and transferred to a transmitter, the encryp-
tion key is available to be shared (synced) by the 
transmitter with other transmitters/receivers via the 
IR port. 
 • Universal: This is the most convenient en-
cryption option available. All encryption-capable 
Lectrosonics transmitters and receivers contain 
the Universal Key. The key does not have to be 
generated by the DSQD. Simply set a Lectroson-
ics encryption-capable transmitter and the DSQD 
to Universal, and the encryption is in place. This 
allows for convenient encryption amongst multiple 
transmitters and receivers, but not as secure as 
creating a unique key.
Encryption Keys
The DSQD generates high entropy encryption keys to 
sync with encryption-capable transmitters. The user 
must select a key type and create a key in the DSQD, 
and then sync the key with a transmitter.
