Lectrosonics DBu-LEMO Digital Beltpack Transmitter
The Lectrosonics DBu-LEMO Digital Beltpack Transmitter includes specially developed, high efficiency circuitry for extended operating time on two AA batteries. It also offers RF power selections at 10, 25 and 50 mW (roughly equivalent in operating range to 25, 60 and 120 mW in an FM transmitter) and thus can be used for a wide variety of licensed or unlicensed applications.
Features:
- Tuning range – 470-614 MHz (UK/Europe Version)
- 24 bit/48 kHz digital conversion
- Tunes across entire UHF frequency range
- 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, maximizing the dynamic range and signal to noise ratio.
