... could i route a signal from my outboard pre into the aux rcv on my 244 and go direct to tape without using the onboard eq? i'm assuming the onboard pres (trim) would still be involved, but i suck at reading schematics and i'm not sure. any help would be ...umm... helpful.
thanks in advance - jv
 
anybody???

...reel, where are ya when i need ya, buddy? anyone know a way to bypass the eq (and possibly the pres/trim) going into a 244 portastudio?
thanks - jv
 
pretty please?

... i just want t know if there is a way to go into my 244 that will bypass as much as possible (eq, pre's) to get to tape?
i know how to do this on the way out, but what about going to tape? if this is a stupid question, someone let me know, and i'll go away:).
reel, are you out there tascam man?
peace - jv
 
The Portastudio 244 does not have direct tape inputs so, there is little that can be by-passed in the way of circuitry to do what you are talking about.

Your best bet is to put all the eq controls at the 12:00 high position to remove their effect on the signal.

Cheers! :)
 
thanks ghost

... i thought maybe i was missing something, but i kinda figured that was the case.
if i go from the outboard pre, and then into the inputs on the 244, is there anything i should know about mixing those pre's?
do folks ever combine their outboard pres with the pre's on a board, in case they need the eq, etc, on the board while tracking?
i'm just curious, since i an essentially doing this out of necessity using my outboard pre with my 244.
thanks a bunch - jv
 
The key to successfully Piggy-backing one pre into another is UNITY GAIN. Meaning that the trim control and channel faders should all be at optimum levels but using a test tone generator that outputs an exact .775 volt signal into the line level input of the channel. This will ensure that the Portastudio's input strip is not adding any noise to the signal chain by overloading or under-loading the gain stage.

Doing that will ensure that your external pre-amp will work within its clean range of gain.

Cheers! :)
 
thanks again ghost,

... it's great to have folks like you and others around to help out.
i think i will try to read up on gain staging to better understand this sort of thing. any articles online anyone could recommend?
peace jv
 
I am not sure about on-line articles about gain staging but the basics of it are this;

Analog circuitry has a range to it. There are signals that pass through a Pre-amp that are so quiet that the hisses, hums and buzzes are audible, then there is a fairly broad range in the middle where the sound you are passing through your circuitry is the only thing you hear because it is above the noise floor of your circuitry and then there hot signals which over tax the limits of the circuitry and clipping or audible distortion starts to become present where the circuitry runs out of power and room to pass your signal though it cleanly.

By trying to keep you signal in the happy middle zone, between -7 to +3db on your meters, you will be operating in a range that is free from background noise and clipping distortion.

Cheers! :)
