Lectrosonics DBu

Description

Lectrosonics DBU Digital Beltpack Transmitter

Tunes across entire UHF frequency range – 470-614 MHz

256-bit encryption – AES 256-CTR

Selectable RF power at 25 and 50 mW

The Lectrosonics DBU Digital Beltpack Transmitter 470-614 MHZ is a 4th generation design with specially developed, high-efficiency digital circuitry for extended operating time on two AA batteries. The transmitter can tune in coarse or fine steps across the UHF television band from 470 to 608 MHz (470-614 MHz for EU versions), with a selectable output power of 25 or 50 mW. The pure digital architecture enables AES 256-CTR encryption for high-level security applications.

Features:

24 bit/48 kHz digital conversion

Tunes across entire UHF frequency range – 470-614 MHz

256-bit encryption – AES 256-CTR

Selectable RF power at 25 and 50 mW

USB port for firmware updates

Wide range input gain adjustment

DSP-controlled input limiter

Two AA battery power

Solid machined aluminium housing

The top panel contains the antenna jack, audio input level LEDs, the programmable function switch and the audio input jack. The LEDs provide red/green indications of the audio level from -20 dB to the onset of limiting to enable accurate input gain adjustment. The programmable switch can be configured as a mute switch, a power on/off switch, talkback, or be bypassed.
Studio quality audio performance is assured by high quality components in the preamp, wide range input gain adjustment 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, maximising the dynamic range and signal to noise ratio.
