DBU-LEMO/E01 - Transmitter

The DBu transmitter is a 4th generation development with specially designed, highly efficient digital circuitry for extended operating time with two AA batteries. The transmitter can be tuned in coarse or fine steps across the UHF TV band from 470-614 MHz (E01 version), with a selectable output power of 25 or 50 mW. The fully digital architecture enables AES 256-CTR encryption for highly secure applications.

• 24-bit/48 kHz digital conversion
• Tunable across the entire UHF frequency range
• 256-bit encryption – AES 256-CTR
• Selectable transmit power at 25 and 50 mW
• USB port for firmware updates
• Wide adjustment range for input sensitivity
• DSP-controlled input limiter
• Powered by two AA batteries
• Housing made of solid, machined aluminum

The top control panel contains the antenna connector, LEDs for the audio level, the programmable function switch, and the audio input. The LEDs indicate the audio level in red/green from -20 dB to the onset of limiting, allowing precise adjustment of the input gain. The programmable switch can be configured as a mute switch, power on/off switch, talkback switch, or bypass.

Studio-quality audio performance is ensured by high-quality components in the preamp, a wide range of input sensitivity settings, and DSP-controlled limiting. Connection options and settings are included for any lavalier microphone, dynamic microphones, and line-level inputs. Input sensitivity is adjustable across a 44 dB range in 1 dB steps to precisely match the input signal, maximizing dynamic range and signal-to-noise ratio.
