Redback Microphone Delay/Mic-Line Recorder

Product Description

Designed to be connected in-line between a microphone and an amplifier to remove feedback issues which arise when paging is executed in close proximity to the output speakers. This is achieved by delaying the output audio. The audio into the mic input will be recorded while the PTT contacts are closed. Once the PTT contacts open, the message will be played back. It can also operate as a mic or line input recording device. In this mode the recordings are activated/deactivated by a momentary closure of PTT contacts. In this mode there is no delayed audio playback. All recordings are stored on the Micro SD card. Up to 999 recordings can be stored on the card before they are overwritten automatically.
