Williams Sound Digi-Wave DWS INT 3 300 - a wireless interpretation system specially designed for conferences and meeting rooms. It is intended for audiences of up to 20 people and can operate on one or two channels.
The system consists of:
- 2x DLT 300 transceivers with individual charger
- 20x DLR 360 receivers
- 20x alkaline AAA batteries BAT 010-2
- 2x headset microphones MIC 044 2P
- 20x surround earphones EAR 022
- 2x silicone cases CCS 044
- 1x charger for transmitters
- 1x protective and transport bag CCS 042 DW
The system can be used in 2 ways. Using one of the two transceivers to send to a translator, while the second transmits the translation to the audience on a separate channel, or by using both transceivers to send two separate translations directly.
Additional DLT 300 transceivers can be purchased for situations where there are more translators, as well as DLR 300 receivers for situations when the audience exceeds 20 people.
