Forgive my ignorance (vintage amp input question)...

I’m currently using (and am quite happy with) a vintage Accuphase E-303 integrated amp. I am wondering whether it might be possible to hook up an a/v source to one of the two DISC inputs. My CD is connected to the AUX, and the tuner to its natural input.

I assumed that the answer would be "no", but as I looked over the spec sheet, I wondered whether the amp might have been designed to allow a tape source into one of the DISC inputs, making it a line input (?).

In any case, I appreciate any insights, and here’s a link to the spec sheet.

Cheers,

Tony C.

EDIT – Well, I just tried using the TAPE 1 function (via DISC 1) with the CD player, and it works perfectly, so apparently there are at least three (and probably four) line inputs. Cool!

Should I have any concerns, or am I good to go?

Tony- Disc 1 and 2 are phono inputs. As such, they will provide a much higher level of gain than you should need, which may or may not be a problem in your particular set-up, but they also will overload easily with a line level signal (particularly when the head-amp is ON) and more importantly, will alter the tonality of the signal by passing it through the RIAA equalization circuit. 

So they will work with a line level signal  but will not preserve the proper tonality.

Ah, thank you. Odd that the CD sounded so good when I tested it.

How difficult would it be to modify one of the inputs to use as a second AUX?

Another question – and I may well remain confused – as it appears that the DISC channels were also designed for a TAPE function, would the same (gain and RIAA) issues hold true? In other words, is it possible that the amp is designed to defeat those issues by switching to a line level input when the tape function is engaged, or is it just wishful thinking on my part?

Thanks.
