Iron - two circuits connecting Covox'a.

* S T A L L *

 Section * IRON * I-would return to the question
COVOX'a connection.
 So two shemki:

+12 M-ma D1 - KR572PA1 (a)


           January 16 X

           February 1915 ¡The Amplifier
GND March 1914

   S9 April 13 GND

   May 12 S1 S8

   S7 June 11 S2

   July 10 S3 S6

   September 8 S4 S5


              D1
 Signals S1 ... S9 corresponds to the signal output of the 
printer port (RS-232) with another (or D, or otherwise) marking.

 The signal from the foot of 16 m, we have D1 "hangs in the air.
 This scheme was kindly provided by VMG .
 And this shemka provided WOXONOM that is,
been and will be there AMADEUS'om (:-))) from FLASH.


        R1
S1 ¡The Amplifier


        R1 R2
S2 par:


        R1 R2 R1 - 15kO
S3 R2 - 7.5kO


        R1 R2
S4


        R1 R2
S5


        R1 R2
S6


        R1 R2
S7


        R1 R2
S8


        R1 R2
S9


                 R2



             / / / /
 Signals S1 .. S9 similar to the same signals in the previous 
scheme.  She, schemes, there are pluses and minuses:



  Type COVOX'a plus or minus


                   Good kach.zv. Costliness

  KR572PA1 (A) and m-we

                   Chorus. mixes. Often "broken"


                   Low cost Poor

   Resistors mixing

                  Easy to Connect. channels.

 Due to the fact that COVOX is a 4-channel -
LIMITED DAC, the main thing - it's the quality of the mixing 
channels. In this connection, I would suggest to put mi - 
kroshemny option.  But due to the fact that most chips are sold

already with zgorevshimi bits, then the quality may zvyka
very lame.
