As far as I can tell the A77 is now regarded as a +3dB taperecorder. Has anyone ever tried to align the A77 to a higher reference level say +4 +5 or +6. I know you would need a +6 tape recording tape to try this but how did things work out. Can it be done or were there problems. I would be...

Thanks for your reply , it is interesting n Maybe 10-14dB peaks with professional recording but A77 never had that headroom anyway even using a low 185 nWb/m as 0 db reference level. Studers etc maybe able to cope with 10-14 dB peaks above reference level as their electronics are probably built...

Thanks for your reply You are right about headroom. I dont know what the headroom is on a B77 but I did measure my A77 about 14 years ago and dont remember the exact figures but after I had already set the reference level to +3 dB I think that the recording headroom was about 8-9 dB and the...

Hi Robert I have my A77 in storage together with my test equipment as I am staying with my sister while the purchase of a new home for me and all my goods goes through. So I can do nothing right now When I am settled in at my new place I think I will completely calibrate the A77 to a +6 dB...

Hi Robert No, it wasn't higher bias I was enquiring about, it was have you ever tried using the A77 at a higher reference level. For example....the ORIGINAL reference level was 185 nWb/m = 0dB 250 nWb/m = 0dB equals +3dB above...

hi Robert, thanks for replying I looked at the MRL site a couple of weeks ago and yes, it is very interesting Do you have any info about my question ? In the absence of anyone who has definate info to the contary I am going to assume that A77s left the factory calibrated at either 180 nWb/m @...

Does anyone know at what recording level the Revox A77 was set up for when the machine left the factory new. Was it 0 db using a 185 nWb/m test tape Was it 0 db using a 257 nWb/m test tape Or was it some other level. Or was the level changed during the production run as better tapes...

I know that an XLR plug or socket is a connector having just designed and built a microphone preamp with a phantom power supply for the mike. I just wondered if there was an industry standard for whether the preamp has a plug or socket on its mike inputs as I have checked that the preamp is...

So IF your preamp has an XLR input for a mike then this would normally be a SOCKETt input and your mike would normally have a MALE XLR plug fitted to it. Can you confirm.

Can anyone help On professional equipment is a condenser mike normally fitted with a XLR plug or XLR socket. Thanks

a77 Head wear The photo of the heads is quite blurred so it is not possible to give an opinion. Can you get a sharper photo ?

There are several ways out of this problem. 1. Do as the previous post suggested and dont record in the same room as the computer. 2. Quiten down your computer which is what I did. There are several things you can do. A. Fit a quieter power supply. They have larger fans which dont rotate...

I cant be certain but I cannot think of a satisfactory way of getting a A77 to work at three different speeds. Apart from actually achieving three speeds mechanicaly there is the problem of setting bias and equilasation of the frequency response. The equilasation and bias for the 15 ips speed...

Just a few further thoughts about the MK319 after it has been modded. I modded mine a couple of years ago and changed the Fet this year to the SK170 BL. Until recently the only other mic 1 had for comparison with the MK319 was a Shure 545 which I bought 25 years ago. I have now aquired an...

Seems that you are going along OK with the mods. Dont forget to put the screws that held the plastic discs back after removing the discs. I replaced all the electronic components on the board including the Fet and increased R1 and R2 to 1 gig. If you dont relish changing all the components...

I dont think any article from a magazine ever got posted. Try using the search facility. Type in MK319. Plenty of info is available.
