ERRATA CORRIGE: The two motors of the C844 are dedicated to the cassette transport operations. The double speed is obtained simply increasing the velocity of the same two motors.

Correct! This is the case with so many other decks out there too. A whole slew of Technics brand cassette decks have 2 motors. One precise speed motor dedicated to drive the capastan only and another motor for other tasks like winding the tape forward/backward. ALSO, the tape speed is changed by changing the speed of the capastan motor. The other motor does not change.

I took the plunge and bought a cassette deck almost one year ago. Now I have vinyl and cassettes both spinning happily making me happy.

You are most fortunate my friend, that 844 is a fabulous unit that can well hold its own among the giants. Thank you very much for reminding us how truly special it is!

Try recording at both speeds WITHOUT Dolby C. The higher speed should capture all the dynamics, with naturally lower tape noise, but without the slightly compressed character that Dolby C usually creates in a recording.

I had a C-844 in the 80s but lost it in a house fire. Could tape UK Radio 3 broadcasts and from my Linn, Ittok, Asak without any appreciable loss from the original source. Beautifully engineered and a joy to use.

Hello ANA[DIA]OG, thank you for a great introduction. I bought the C844 sometime around 1981/82... 1200DM / 600Euro was a lot of money. I bought the C844 for my choir recordings. In an AB test (C844 against HIFI video recorder (3000DM)), the C844 was equal. (C844: double speed, Dolby C and pure iron cassette)... Of course the video tape / with helical track was unbeatably cheaper... The whole thing was topped off with my ASC6002S and the Super-D noise reduction system from Sanyo. However, that was a different league and an 1100m tape for 60DM was quickly sold at 38 / half track. I still have the C844 today. LG Manny

@@anadialog For starters, KZread does not play audio at 320kbps, even on the highest video resolution. It does not come even close to 320kbps. KZread uses two types of audio formats - AAC (wrapped in an MP4 container) or Opus in a WebM container. For AAC, KZread will play a maximum audio bitrate of around 126 kbps. For Opus, it can be between 56 kbps and 165 kbps. This is regardless of the audio source format being uploaded because KZread will automatically re-encode videos to use their format. So even if you upload a video with 24/96 lossless audio, KZread will convert it to 126 kbps AAC in an MP4 container

nice vid! i was close to throw away my collection of tapes from the 80ies, assuming poor quality after decades, car use and because i never payed much attention to equipment and settings those years. this year i got me a harman kardon TD212 (1988-1991 in the 600 DM price range....so half the price of your C844) for 25 euro on ebay, just to check those tapes. the sound blew me away, much better than i remember (and obviously today i have better speaker and amp too) i can only agree with you that tapes DO sound good and i would add, you dont necessarily need a high end tape recorder such as the c844 to enjoy good music. definitively nice addition to vinyls.

I like this deck. So much, that I have two of these. I have to disagree about the performance difference between normal and high speed. Especially with ferric tapes, the higher speed transforms the performance to a level that becomes truly amazing. Perhaps the source of the content you tried didn't contain much high frequencies but with content that has a high dynamic range and high frequency content, the differences become pretty apparent. And if you forget about the built-in dolby and use dbx, then the results are simply astonishing. No need to use metal tapes at high speed.

i just got a sony tc k81 for 500$ and because i record all my tapes at high speed i modded the speed regulater circuit by bypassed the speed controls limiting resistor 100K and putting in a pot with a much higher resistance from 150k to 250k now the deck can play and record anywhere from .5X all the way up to 4 times normal run speed. it sounds amazing and im considering changing the values of the bandwidth limiting capacitors to i crease bandwidth.

Sorry for the late reply, the answer is YES to all!

Nice, i would calibrate the double speed back to just 5 cm/sec, just a significantly bit better but still up to 40 minutes a side on a C90 tape. Otherwise i probably redesigned it completely (Mod) so i could use 18cm tape-deck reels. In my understanding you could use all the electronics besides the heads "of-course" also for standard reel tapes. That way you have Dolby B/C and 9.5 cm/sec up to 90 minutes a side. It's a lot of work creating a machine like that but you do it only once and keep it forever, right?

I would think that the double speed would improve the SN ratio and MOL of higher frequencies of the audio material, and not necessarily the frequency response. During recording, decent decks utilize an EQ curve called "pre-emphasis" which is applied to counter the effects of self-erasure of high-frequency signals. High-frequency wave prints are so close together that they are in danger of cancelling out each other. With a higher tape speed, the prints are spaced further apart and the tape can hold a higher bandwidth before EQ is necessary. I would assume that the EQ during double speed isn't as drastic as the EQ during normal speed, and as such, the tape doesn't saturate and distort quite as easily.

Quick question. Is a fisher DD-300 with vu meters good as well? Unfortunately couldn’t find the model in this video you mentioned around my area 😖

Gotta give to have! But I wouldn't say twice, it's not proportional.

As you did state in the comments these two motors are for transport of the tape, not to make it double speed. Here is how and why this was done. As far as I know this idea started with the open reel-to-reel tape decks to lower wow and flutter problem, keeping tape speed very constant. However they used three motors. One for each reel and one to drive the capstan that pulled the tape across the heads. This meant that there was no possibility of any extra drag on the motor pulling the tape across the heads and meant a steady speed. Each reel motor was used at a lower voltage to pull up the slack and keep the tape from coming off the reel to easily, then it ran higher voltage on the RR or FF modes. For a cassette they just did not bother with the third motor to the full reel side but only used it for the take-up reel in play and rec mode and for other fast tape movements, and a separate motor for the capstan. Good demo ... I have a Sony two motor unit.
