Introduction
The DBu, DBu/E01 transmitter employs high eciency
digital circuitry for extended operating time on two AA
batteries. The transmitter can tune in coarse or ne steps
across the UHF television band from 470.100 to 607.950
MHz (DBu/E01 frequency range is 470.100 to 614.375
MHz), with a selectable output power of 10, 25 or 50
mW. The pure digital architecture enables AES 256-CTR
encryption for high level security applications.
Studio quality audio performance is assured by high
quality components in the preamp, wide range input gain
adjustment and DSP-controlled limiting. Input connec-
tions and settings are included for any lavaliere micro-
phone, dynamic microphones and line level inputs. Input
gain is adjustable over a 52 dB range in 1 dB steps to al-
low an exact match to the input signal level, to maximize
the dynamic range and signal to noise ratio.
Frequency Agility
The transmitter tunes across the entire frequency range,
from 470.100 MHz to 607.950 MHz (DBu/E01 frequency
range is 470.100 to 614.375 MHz).
Encryption
When transmitting audio, there are situations where
privacy is essential, such as during professional sporting
events, in court rooms or private meetings. For instances
where your audio transmission needs to be kept secure,
without sacricing audio quality, Lectrosonics imple-
ments AES256 encryption in our digital wireless micro-
phone systems. High entropy encryption keys are rst
created by a Lectrosonics receiver, such as the DSQD
Receiver. The key is then synced with the DBu via the
IR port. The audio will be encrypted and can only be
decoded if both DBu and receiver have the matching en-
cryption keys. If you are trying to transmit an audio signal
and keys do not match, all that will be heard is silence.
