Sennheiser Introduces Tourguide System 2020
At InfoComm 2006, Sennheiser is introducing the industry's first digital wireless tour guide, the Tourguide System 2020. The fully digital transmission system, which allows a guide to address a tour group on wireless earphones via a hands-free microphone, offers superior intelligibility and reliability of operation due to increased insensitivity to interference compared to traditional analog systems.
Sennheiser's engineers have integrated all of the wireless receiver components into a single hands-free unit that weighs just 65 grams, including batteries. The receiver can generate sound pressure levels of more than 120dB, which is sufficient for the guide's voice to be clearly heard even in noisy environments, such as factories or busy streets.
Operation of the lightweight receiver is very simple. Opening the receiver's ear bows switches the unit on for the selected channel. Removing the unit and closing the ear bows returns the device to standby mode. Changes in level are made using a large volume wheel while a switch located in the center of the level control provides channel selection. The LCD readout displays the selected operating frequency and channel identification, indicates the current volume level and provides battery control.
The system's belt-pack transmitter and headset offer hands-free communication with the additional advantage that the fixed distance from the tour guide's mouth to the microphone insures that the voice levels remain consistent at each receiver and do not require constant adjustment. The belt-pack transmitter has two audio inputs, one for the headset and another one for line signals, each with separate sensitivity adjustment. A mute switch on the microphone input allows the operator to continue talking over the line input, or to distribute only the line level source.
For system operators, the absence of any cables means that receivers can be quickly returned to their charging and transport case ready for the next group of users without the need to untangle any wires. There is also a compartment for a handheld microphone. The handheld mic may be used with the wireless belt pack transmitter using the supplied cable.
The tour operator may adjust a single receiver to a specific frequency channel, place the receiver into the copy slot in the case, then press the copy button to assign all receivers to the selected channel. All receivers are delivered at a comfortable volume level that can be adjusted individually by the visitor if required.
The charging and transport case accepts ninety 240VAC at 50-60Hz and can accommodate twenty receivers plus the belt-pack transmitter. Three hours of charging time guarantees at least eight hours of operation.
