- Test signals on CD are from Audacity app
400 Hz for LEVEL
10 kHz for BIAS
All at 0 dB peak level meter
p.s. for reference 10 kHz should be adjusted at -10 dB peak level meter

Eventually simply understood what on the manual was totally ignored. Thank you. Great simple and clear video tutorial
Это красота того времени .... спасибо кто это создал....
I have never thought that recording on a cassette tape will be this good if done properly, with proper deck, tape type, and adjustments. Thanks for sharing. Now am thinking that my original cassette tapes purchased in the 80's and 90's can even sound better on a good quality tape deck.
and there are much better sounding decks ,being this one of the best ,in terms of evolution, to hear cassettes if not in your budget to buy a Dragon that is not that good as they say, but also the 90´s pioneer decks with the function FLEX while playing must be always on ,this if you´re cassettes were well built and good recorded ,and there is no similarities with paly trim from Yamaha, i have the CT-S603S and works very good with any cassette i put there to play they sound good as the day i recorded them from 20 to 40 years ago. This even seems a azimuth correction but isn´t
Those models are my nostalgia since 1992 !!! Thanks for uploading!!!
these decks are from 1988...

The very tape deck I would have loved to have back in the day but was out of reach for me financially so I ended u with a Pioneer CT-447. Memories from the early 1990s.
I have that Cassette Deck, I am actually using It now to Transfer Old tapes to CD for a Mate (Lockdown Blues). I bought It new back In the day, and Never needed another tape deck since. Mine Is the Black model one, and the best thing Is NO BELTS, as It Is Direct Drive like the SL1200/1210 turntables. So No pitch problems or slipping or tightening of the Tapes. The Calibration Is smack on the money. You can change the Meter reading to match what You are doing and for better Calibration on some Rough Tapes. Everyone I have done tapes for over the Years, say they still play them and they still Sound great. I always used type2 chrome tapes, I still have packs of unopened ones. As the Maxell Factory was just up the road from Me, and Mate would bring Me loads every week. I like the Matching CD player never seen one of those before outside a Radio Studio. Thanks for the Review. And Stay Safe.
Esistono comunque molti modelli direct drive che essendo sistemi a doppio capstan,hanno comunque una cinghia collegata ai due volani,questo sistema serve a far funzionare il volano e il capstan di sinistra.in questi sistemi il direct drive lavora solo sul volano e capstan destro
Глаз не оторвать!!, красотища!!
Good amplifier good player . Enjoy good music .
These look better than the dark-gray Technics cassette deck and CD player I got from Sears around 1990.
the "normal" colour of the components of this series is black; they're rare silver versions
Dear Marcus!
Thanks for the instructive video, it helped me. Big thanks.
And one more question: the SL-P770 in silver is a rarity, very little to see this beautiful and especially high quality machine.
And where do you have this probably the rarest rarity of the RS-B755 in silver? ... they only made it for you in OSAKA only one?
There's a lot of RS-B755 in anthracite ... but I haven't seen silver in any Technics catalogs.
Good luck in your creation of such interesting videos and stay healthy. Sincerely, Erik Majcher
Hello! I LOVE vintage!
Oh nice equip , got a darkbrown SL-P770 over here. Bias in general rule of thumb: bias to low , bass/bottom end missing. Bias too high audio get s compressed high tones getting thin or missing
Happy people love old... Childhood mameries
on this tape for calibration it is better to choose the level minus 10 20 decibels. At a record level of 0 decibels, an overload occurs at a frequency of 10 kilohertz.
wow this is a nice pair use to have one just like this one!😍
Very nice Tape !
Его Величество - ,,Техникс,, !
Very nice components 👍
i have the same deck but the cd player bought one under that model also in light grey, but after a year or two i bought a top end model from technics but without a jog shutle or whatever they call it, but looks very nice that model , i should have paid a bit more and kept this one
Maravilhoso aparelho espero poder possuir um desses parabéns
Good film! Thanks!
And that's how you record on a tape.....properly!
👍👍👍👍
Nice idea
I am happy this video. I am in like.
Que bien suena la grabacion !!
Hello Marcus. I searched the whole internet for the Technics RS-B 755 in silver and nowhere found one. can you tell me where you bought your Technics RS-B 755 from. is that maybe a japanese model? nowhere can I find a silver Technics RS-B 755 deck. It can't be that only a silver deck was made of it. thanks for your answer

OK guys, I need some clarification.
Bias calibration means setting the bias value on the deck, so that a specific cassette tape reproduces the frequencies of the source as close as possible. I'll have to check what is the dB value for my Nakamichi BX-300. I have 10 kHz test tone if that's what is needed.
But what is level calibration with that 400 Hz? What kind of test is this?
Thanks.
It's for recording sensitivity to match the output level of the source material.
Super Matériel ! Superbe video
Bonjour j’aimerais savoir ou avez-vous acheté vos lecteurs svp
I really want this one..
No. This is not the right mode to calibrate the tape.
Enought right but not at all the use for the 315 Hz, but If you think to record a 10khz test tone at 0 db to calibrate the tape as linear, you show not to know the basic magnetic recording information...
Can you explain the right way how to calibrate a cassette sir ?
It would be very interesting to me ... thx :-)
@@Badassvidsz I' m a technician for the Technics service here in Rome.
All the tape deck doesn't record all the frequency at 0 db vm cause the produce of hard saturation in the rec head and tape, this creates level loss and distortion. The frequency responce of a tape deck machine is always refer to a -20db vm, at o db the frequency responce riduce itself to 6/8khz max, even you use the Hx pro.
So, adjusting the bias with 10khz at 0db is absolutely wrong.
Unfortunately it is not possible to performe the bias adjust using the deck level meter, because at -20 db reading all the display deck level have little sensibility for little level changes, so precision is very low.
So, how we can do without a professional laboratory's meter? It's simple: using a pink noise.
Recording and adjusting the rec level at -20 db meter reading in rec/play mode with a 3 head tape deck, switch continiusly from source to tape and adjust the bias control hearing the differences in high frequency. After, adjust the level at 315hz 0 db meter ( better at -10db meter, if possible ). Repeat 3 times the two steps.

Ciao! 🤟

Thank you very very much sir and yes you are right another dude replied back to me and he said the same things here in an other comment of mine you may see it if it is visiable ??
personally i thought that the calibration was done at 0db or in between the arrows i have the RS-BX707 which when calibrating it shows the arrows only not the db .
Thanks again and much love from Greece and i'm happy Italy goes better from this corona virus :-)
@@Badassvidsz Thanks, i hope this for all the world also.
@@TheDrummer64 Yes of course :-)
Super
Good dake
Who in his right mind uses a 10kHz tone recorded at 0 dB on a basic ferric? Bias is calibrated at -20 dB to circumvent running into the tape's saturation. If you use a level that high, you surely will end up with severe underbias which will falsify your sound reproduction.
You are right! -20 dB or internal calibrator for for easier use.
@@AVadim I use pink noise at -20 dB and good headphones if I don't have internal test tones for calibration. On a 3-head deck, it is very easy to set the proper bias that way. Just compare source with tape and adjust bias until tape matches source in the treble as best as possible.
@@svenschwingel8632 My Pioneer T-700S (CT-S910 in Europe) have autocalibration on three frequencies, TEAC V-6030S - manual calibration with internal generator.
@@svenschwingel8632 i agree, is the Best way imo.

А разве частотный генератор не встроен в эту деку? Явсегда думал , что дека сама подаёт частоту на головку и уже потом, в зависимости от того, какой ответ с плёнки, такой и ток подмагничивания пойдёт на ленту. У маня А&D Akai дека я всего лишь нажимаю на калибровку,запись и уже потом кручу биас и левел.
This is the RS-B755 model, which does not have a signal generator. In my collection, I have the Technics RS-B965, which is equipped with a signal generator. If you have an A&D deck (AKAI), you surely know that only the highest models of this brand have such options. The rest do not. The same applies to Technics and other companies.
Nice video, i got one of these yesterday... there is a loose spring on the lid I don't know where it goes, can you help me? Thanks
Bonitos equipos.
In the discription you've written
>
why that ??
I've also noticed that you've adjusted it at 0db .
if you look into Technics service manual BIAS adjustments are done at -20db level to avoid oversaturation. The frequency response curve is done at -20 as well.
That also means that when the deck has inner test tones, while calibrating it moves the sensitivity of the VU meter to -20db.
@@BlackBunik
Thank you very much for the reply sir ,
never knew that i thought that it was really at 0db :-)
The more we grow the more we learn :-)
That’s not how level calibration is done, you would need the factory test tape where the level is set at the factory. CD line out is not a good source for calibration.
It's all In the player. i have never used a Tape or anything else to do the Bias or calibration on Mine. You can change the read out of the Meters, and this gives You the Calibration Meters and Generates the sound. Neat yeah!.
TheBudgie29 I’m talking about the maintenance calibration not the recording level check.
@@Capturing-Memories I get You. No I don't have one of those Tapes. I have have never needed to re-Calibrate from out of the Box New. It would be quite hard to find someone who knows how to do that sort of thing. Or even have the Proper Equipment.
4:57 копия не много хуже.
Copy, slightly worse quality. BIAS, turn to the right, it was necessary more. Tuning by ear will be more accurate.
Ну потому они и КОПИЯ. Как она может быть лучше оригинала?

I have an Audacity app. It is not clear how to correctly generate a test signal, the wave should be sinusoidal, square?
I use sinusoidal and pink noise for manual calibration at -20db level
Hello! I have such a tape deck. How did you make the test sd? Where did you get the "image" to burn the disc?
I found on torrents images of test CD. But my deck have autocalibration. :)
Just generate it and then burn it onto cd
wow
Which remote control is suitable for technics sl p770
Actually, any Technics/Panasonic remote for the CD players of and around that era should be compatible. Hope this helps

А нём нет встроенного генератора?
Technics RS-B755 не имеет генератора.
Понятно, но как-то странно калибровка то есть и даже ручная поканальная, неудобно однако.
