AUTO ATTENUATOR (AUTOFADE) 2 VOICES WITH A 27HZ DECODER
THE AUF227 is identical to the AUF200, with a 27 HZ integrated decoder. On this device, the passage from a channel to the other one can be made, either on the presence of the modulation on the channel B, or on the sending of one 27 Hz present in the modulation of the channel B, or on a combination of both.
Description
The switching by an outside loop is also possible. On request, the detection of 27 Hz can be made on the channel A and open the channel B. It is the case of a satellite receiver where the latter authorizes the pull-out.
