The new DCHT/E01 transmitter is designed for use in film and television production to provide a wireless link from a bag or cart system to cameras and recorders. The transmitter will accept mic or line level analog signals or AES digital signals from a mixer and transmit the signals to the receiver in a pure digital format. The digital architecture is a third 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 470.100 to 607.950 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, stereo 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 51 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.

The top panel contains the antenna jack, two audio input level LEDs (one per audio channel), the programmable function switch and the audio input jack. The red/green LEDs provide audio level indications from -20 dB to the onset of limiting for each channel for accurate input gain adjustment. The programmable switch can be configured as a mute switch, a power on/off switch, or be bypassed. The 6-pin input jack accepts two mic or line level analog signals or AES digital signals from external sources via a variety of adapter cables. Analog inputs can be linked for the same gain when used with a stereo source, or operate independently with individual settings.

The housing is constructed of solid machined aluminum for lasting ruggedness. The exterior is finished with an ultra hard, dark electroless nickel finish.
