The ParMarLow Witness Interview System allows for prompting the interviewer without interrupting the interview. The line of questioning can be directed without alerting the suspect. The short range (100 to 200 feet) of the system keeps the transmissions in house. Used with the ParMarLow WR-PWRx07 Wireless Earpiece, the suspect is unaware that the interviewer is receiving information from the investigative team. This is extremely valuable when interviewing children and young adults who are very aware of their surroundings. ParMarLow bundles the Okayo Wireless Microphone system with ParMarLow's own wired or wireless earphones to make a reliable low-profile prompting system costing less than most law enforcement two-way radios.
The ultra-portable 50W Dual Audio Pal from AmpliVox is designed to deliver crisp, clear sound from up to two microphones at once, and stream music and other audio for all types of indoor and outdoor events.
