Method and device for digital wireless transmission of audio signals

摘要

In a method and device for digital wireless transmission of multi-channel audio signals from a player having a sender to at least one loudspeaker having a receiver, a signal picked up by the player is scanned based on clock pulses supplied by a quartz-controlled clock generator by a scanning rate converter provided in the sender. Clock recovery is employed in the receiver. The clock pulses of the clock generator are adjusted so as to coincide at least substantially precisely with a center frequency of the clock recovery of the receiver. In an alternative configuration, the scanning rate converter is replaced by a combination of a digital-to-analog converter and an analog-to-digital converter.
