TalkPerfect Speech Transfer Kit 4
|
| Overview |
| The
TalkPerfect Speech Transfer System is designed to improve
communication at fixed screen security counters. The
TalkPerfect Speech Transfer Kit 4 provides optional use of
the POD microphone / POD speaker on both client and staff
sides for aesthetic reasons. Based on proven, reliable and
patented technology, the full duplex (two way) system
amplifies speech for both the client and staff while
minimizing background noise and actively reducing acoustic
feedback |
