TV Sound Encoders/Decoders
The AK414X series is a sound multiplex decoder/encoder for digital TVs/STBs. Encoding/decoding by a newly developed digital technology, the AK414X series does not need many external components that were necessary with traditional analog decoders/encoders. In addition, they have good performance in characteristics without any adjustment, eliminating the need for alignments on the factory shipment.
