Tape Tech / Alignment with software...

« on: October 21, 2011, 09:25:58 AM »

Hello Alignment-Specialists.

I am trying to learn how to align my tape machines, in this case a Studer A807.
The use of the software "audioTester" seems to make sense.

Please see attached graphics.

I would like to know, if this is the right way and if my results are acceptable (maybe a hint, what could I do better).

The software gives a sweep from 20 Hz - 20000 Hz on the output and draws a graph for the input.
I adjusted with a millivoltmeter and a scope. Then I used the software and "cleaned" the curve as goog as possible.
Here is the result plus a second graph showing only the hardware without the tape machine (Cables XLR-In directly to XLR-OUT)

Thanks a lot!

Reel to Reel Tape Machines / Re: Tape Project machines from European perspective

Hi Robert,

yes, yes, these US-guy's are often doing there own thing... (JUST JOKING!)

The tapes from TP are recorded in CCIR not NAB. That's the European standard and makes it easier for our Revox, Studer, Nagra, etc.
ATR 100's are hardly available.

Buying the 810 is definitely right. I own them both, 810 and PR99. Not compare able, by mechanics and sound.
I can not recommend to by an Otari. I needed months to find a service for a BTR-5 in Germany. It is a great machine, but they told me there are not spare parts for Otaris.

Reel to Reel Tape Machines / Re: Otari BTR-5

Dear Paul,
dear Dan,
dear Steve,

sorry for the late reply (saw The Eagles in Berlin) and thanks a lot for your answers.

My Otari has 3 speeds up to 15 ips, NAB and CCIR and tape A/B.
1/4", 2 track, just right for the TP tapes...
Don't know when it was build...

I downloaded the MTR-10 manual and will see how far I come with it. My Otari does not have the external accessible cards.
I am waiting for the approval for the tech-group...

My biggest problem is that I am (as an mechanical engineer) fighting with the alignments and measurements of tape machines in general but that's only my problem...

My main machine is a Studer 807.

regards

Reel to Reel Tape Machines / Otari BTR-5

« on: June 24, 2011, 07:39:12 AM »

Hello everybody! My first post here...

I bought an BTR-5 on ebay, very cheap.
It's working fine and sounds good but I do not have a manual and can not find a source.

Can anybody help?


Thanks a lot
