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.
