Noise Reduction System

add a review add a review



For all audible intents and purposes, the DBX system found in the NX40 eliminates tape hiss.

But it also increases the overall dynamic range capacity of a cassette deck, letting you record both louder and softer sounds than you are used to.

The combined result is that the NX40 will let you make cassettes with nothing added, ones as quiet as (and virtually indistinguishable from) the original.

The DBX noise reduction system can't do anything to improve noisy sources (records, broadcasts, other tapes) - it won't make them quieter - but it doesn't let anything be added.

With a really quiet source, the cassette copy will be crystal clear and just as wide in dynamic range.

If you haven't used DBX before, you'll be startled at how close to identical the copy sounds.

Now no dynamic range (even digital) is too wide for your cassette deck.

No other noise reduction system can do this.
