More volume Required!!!! BF533 - vina...@yahoo.com - Jun 3 3:52:00 2005
hi
I have BF533 EZ KIT lite . I am running the talkthrough application on it .
I am driving the input point Audio-in ( j5 ) of bf533 from the line out from
the computer system.
However to much of surprise i found out that the volume of audio coming out
of audio out ( j4 ) of bfs533 is very much less compared to the volume at the
driving point.
please tell me the configuration settings for the board so that volume of
audio output is comparable with that at input to the board.
with regards,
vinay kumar

Hi Vinay,
Some things to thing about:
1. Verify that the settings for the CODEC correctly
set a gain of "1". This involves reading and
understanding the DSP code and the CODEC itself.
2. Verify that the analog stage on the board sets for
a gain of "1".
3. Verify that the impedances for your input/output
match, so there is no attenuation.
Correct with code on the DSP, either with CODEC
configuration or with signal gain (multiplication).
