 We present to your attention a mu-
sound card Soundrive v. 1.05, times
by Flash Inc. and taken from me from
demo of the same name.
  Some comments on the first diagram.
The circuit represents Soundrive itself.
 Scheme 2 




Switch S1 in the diagram serves to re-
circuit connections: Sounddrive/COVOX.  With decoding
radiator DD1 from feet 11, 14, 15 signals are coming
for 11 legs of DD2-DDS microcircuits and resistor
R-2R matrices similar to those collected
we are on DD2. Power is supplied to the microcircuits
as follows: +5V on leg 16ID7 and 20
leg IR23, ground on leg 8 ID7 and leg 10
IR23.
In order for the circuit to automatically switch
switched to the Sounddrive/COVOX modes, required
we can make a small modification that
shown in diagram 2. In this case, switching
body S1 is removed from the circuit.
To check the correct assembly of the circuit
you can use the test from the demo
program Soundrive 1.02, which has
is at the editorial office of our newspaper.
Personally, I have already collected for myself a relatively long time ago
this device and quite happy with the quality
the music it plays.
