HOW TO USE A WHISPER RADIO-GUIDE SYSTEM (TOUR GUIDE SYSTEM)
The group guide or speaker must carry the transmitting equipment and microphone while each listener must carry a receiver with a headset or headphones. The devices are small in size and should be worn around the neck to ensure reliable coverage. Carrying the transmitter or receiver in a pocket is not recommended because it could reduce the range.
All transmitters and receivers of a group must be tuned to the same frequency channel. Nch software clickcharts. Numerous frequency channels are available.
GROUP SIZE
There is no limit to the number of tour guide receivers in a group. For listeners to clearly hear the guide's explanations, they only need to be within the coverage area or range of the transmitter. The receivers do not interfere with one another.
NUMBER OF TRANSMITTERS
There can only be one transmitter at a time in each group. There may be several speakers with a transmitter in the same group, but they must coordinate among themselves so as not to have two active simultaneous transmitters in the same group.
NUMBER OF GROUPS
When using digital transmission equipment, there may be several groups in the same area or room (up to a maximum of 20 digital transmission groups). For this to work, each group must be on a different frequency channel.
Note: If using analog transmission equipment, there can only be two groups in the same area. It is not possible to add a third analog group in the same area, even if it is in another channel. This is a limitation of the analog system.

Whisper Mat CS is a peel & stick sheet membrane that reduces impact and airborne sound transmissions and isolates “finished” flooring from subfloor cracks. Designed for use with ceramic and natural stone tile where sound absorption is required, specified or desired. Constructed of a cross linked polyolefin foam sheet combined with aggressive rubberized adhesive and a polyester mesh fabric, Whisper Mat CS also has the flexibility and strength to withstand structural movement and concrete shrinkage cracks up to 3/8″ without transferring stress load to finished tile. Additionally, excellent moisture resistant properties make this the most comprehensive underlayment product for ceramic and natural stone available.
