Yes, but I have the same signal on the console, and there I hear a lot

Listening tests are good, but if you're trying to solve a problem, or
determine if there's a problem and where it is, measurements are
better.

If I'm interpreting your setup correctly, you have the console output
connected to the input of your recorder and the output of the recorder
connected back into the console. You're switching (at the console)
between listening to the direct console output (as fed to the
recorder) and what's coming out of the recorder?


No, the input of the recorder is connected to the output of my
soundcard thru a (cheap, sorry) patchbay that routes the soundcard
output also to the console.

And you're losing bass, even with the recorder set to Input Monitor?


Yes, it's not a loss as if you would listening to a vinyl without RIAA
eq, but there's surely a loss in the bass area.

There's something very wrong here, either with the recorder, the
console input that you're usinjg to monitor the recorder, or the
hookup.

Proper alignment requires some references - a known, or at least fixed
(sine wave) input source and, for playback alignment, a standard test
tape.


I have the test tape, and for feeding the tones I'm using sine waves
generated by csound.


If the recorder is operating properly and it's properly
connected to your monitoring system, you can make some adjustments so
that it sounds best, but you won't know where you are in reference to
the rest of the world, and you may be making problems for yourself.

Alignment is simple, but you can't do it without test equipment. And
there's no sense in doing an alignment until you fix all the real
problems, which it appears that you have.


As far as I can tell the recorder works, in the sense that it records
well what's on the SOURCE, but that signal is already degraded in bass
response...

thank you
