Introduction
The DBSM/DBSMD transmitter employs high efficiency
digital circuitry for extended operating time on two AA
batteries. The transmitter can tune in steps across the
UHF television band from 470.100 to 607.950 MHz
(DBSM/DBSMD/E01 frequency range is 470.100 to
614.375 MHz), with a selectable output power of 10,
25 or 50 mW. A high-density transmission mode at 2
mW allows close carrier spacing for maximum channels
within a given amount of spectrum.
The pure digital architecture enables AES 256CTR
encryption for high level security applications. Studio
quality audio performance is assured by high quality
components in the preamp, wide range input gain ad-
justment and DSP-controlled limiting. Input connections
and settings are included for any lavaliere microphone,
dynamic microphones and line level inputs. Input gain
is adjustable over a 44 dB range in 1 dB steps to allow
an exact match to the input signal level, to maximize the
dynamic range and signal to noise ratio.
The housing is a rugged, machined aluminum pack-
age with a standard Lectrosonics 5-pin input jack for
use with electret lavaliere mics, dynamic mics, musical
instrument pickups and line level signals. The LEDs
on the keypad allow quick and accurate level settings
without having to view the receiver. The unit is powered
by AA batteries, and the antenna port uses a standard
50 ohm SMA connector.
Switching power supplies provide constant voltages to
the transmitter circuits from the beginning to the end of
battery life, with output power remaining constant over
the life of the battery.
