The Redback® A 1760 has three modes of operation, determined by DIP switches, which include an Audio Delay, a Microphone Recorder and a Audio Recorder.

When in Audio Delay mode (Mode 0), recording is activated by either the PTT switch on a 5 pin XLR microphone connected to the “MIc In” connector, or by the PTT switch or PTT trigger on the front of the unit. The A 1760 is designed to be inserted in between a microphone and an amplifier (for example), 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 or Music inputs will continue to be recorded while any of the PTT contacts are closed. Once the PTT contact becomes open, recording is completed and the recorded message will play back instantly. The recorded messages are stored on the Micro SD card for playback at a later date if required. A maximum of 999 recordings can be stored with the first message being over ridden once the limit is achieved. An optional pre announcement and/or post announcement chime or message in .mp3, .ogg or .wav. format can also be included with the playback.

When the unit is in Microphone or Audio recording modes (Mode 2 or 3), a momentary closure of the PTT switches will activate recording through either the respective Mic or Music inputs. As the audio is being recorded it is stored on the Micro SD card in the same manner as in the Audio Delay mode. The audio can be “Passed Through” to the Mic output connector as it is recorded, or set to NO audio output. When in “Audio Pass Through“ the “Output Active” contacts will be closed, enabling remote monitoring. Recording is stopped when another momentary closure of the PTT switches occurs. The recording is saved to the Micro SD card and no further action is taken. The recorded messages can be accessed from the Micro SD card for playback at a later date if required. Dimensions: 134mm(L) x 75mm(D) x 46mm(H)
