NAD 6300

[J!m]

I never used any noise reduction beyond DBX which is actually "dynamic expansion" or whatever marketing called it- that did not depend on the original recording conditions.

But with Dolby NR, yes, the same decoding must be used to match the encoding of when the recording was made. Basically a compression that is decompressed on playback, to "preserve" the high frequencies. I never liked recording or playback with it.

yeah you’re right if you don’t use it once you record with it it just doesn’t sound correct.

I’m thinking the 6300 works a little different because of the DynEQ, but the manual tells you to engage Dolby when recording, or maybe I’m reading it wrong and it just means engaged Dolby C when you’re setting the recording level and the bias.

If you ALWAYS had to use it, they wouldn't provide a switch for it.

Using Dolby C and switching on the MPX filter was recommended during the bias fine tune process to assist in hearing any reponse errors caused by over or under-biasing.

It was a long time since I used my NAD 6300 for recording, but most likely I used Dolby C with ferric cassettes..

Curious about your impressions of the "Car" mode thing Nando...

I suspect it's a frequency boost to overcome road noise but no idea really.

That makes sense.

that’s what I’m hearing, it boosts the bass, and maybe the mid range too.

@BlazeES: I hadn't used the CAR processor for recording. Tony - here is an explanation of the CAR processor from the OM:

Dynamic range compression, that would have been my guess.
