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.

 

[J!m]

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...

 

[J!m]

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.

I received the cassette deck yesterday, and first impressions are pretty good. I think this deck is in good original condition, but I believe that the rubber has to be replaced. I’ve never done this before, and I’m not sure if it’s the job for me. If the transport has to come out then I don’t want to take a chance. I lightly sanded the one after the 6300 folded one of my tapes in half and started distorting it. It didn’t eat it, but it messed it up. For right now it’s working pretty good, and I just have been listening to tapes that I made on other decks. The play trim is nice, especially with my older ears I don’t hear as good as I used to, and with that adjustment it sounds like you can raise and lower the highs approximately 2dB either way. Supposedly the belts are in good shape, and right now I’m just running some tapes through it and trying to work out any kinks.

Note to self;

Do not put a good metal tape into a deck I know nothing about

Also this is a no-frills deck, and I’m used to my other one that has a bunch of settings. Not much to look at, but it does have some spectacularly fast meters, and I’ve never seen meters this fast. No peak hold on the meters, but I saw a mod online and the guy got his 6300 to hold the peaks with some kind of addition to that circuit.

@J!m pointed me to a technician in Connecticut, and he only does Nak decks, but that gentleman pointed me to a retired NAD tech also from that neck of the woods. Thanks for that! I figure this has to be the guy too fix my deck, and from what I understand there’s about 20 pots inside that need to play nice with each other, and they definitely harder to work on than your normal deck. Definitely a keeper, and I can’t wait to make some recordings. Looks like a snow day coming up in the northeast, and some frigid weather coming, time to heat my place up with some wattage lol.

The NAD playing through my Marantz receiver. I purchased this receiver about three years ago, and although it was recapped, the person who did it mixed all the wiring up for the front panel. The funny part is the guy that I bought it from said that it sounded good, but you can tell there was just no imaging, the sound stage was all over the place, no phantom center channel, I know that the latter is psychoacoustics but it was just messed up.

It’s spent a year at Morts TV in Levittown PA, and he just took his time and straightened it out. For those that have worked on these receivers (2385) you know that they are not as repair friendly as the Pioneer, Sansui and other monster receivers from that era. I know he could’ve got it done quicker, but I just let him go and work his magic, and it came back sounding absolutely fantastic. As a teenager I used to drool over all of the Marantz/Pioneer/Yamaha
gear at the local hi-fi store, and my buddy had a Marantz receiver. Just flipping that Gyro wheel for the FM tuning was enough to hook and reel you in. Anyway she is my daily driver, and it sounds so good that I don’t ever see me getting rid of it.

Besides a good tape path cleaning for the capstans and pinch rollers, it will be up to the technician to remedy the tape skew.

When I get a "new" deck, my sacrificial tape for testing is a pre-recorded Michael Bolton - and it has lasted a long time. Damn!



It's good to see your NAD 6300 arrive and in action. I have a few vintage Marantz components I've been collecting for an all-Marantz stereo system - excluding speakers.

Nando.

If the Nak tech can work on a CR-4, he can work on a NAD 6300, it's almost the same mechanism.

Yes - as quoted from Lutz:

"Sankyo Direct drive = Nakamichi MR1 = CR 4 = CR 5 = CR 7 = BX 300 and so on.... "

Haha!

It's the bastard's revenge after all we did to him....

An appropriate use for Michael Bolton...

It developed a problem about three tapes in. I think it’s what they’re describing as a bad spot in the motor, the take up reel motor. It’s shutting off about halfway through a tape, that causes the tape to have a loop in it, but it doesn’t eat the tape. He had it to a technician, and I’m really not happy about this because it was supposed to be 100%.
