Problems With Volume Settings / resistor values
"kak wrote in
I am using Quad 34 & 606 II amplification with a Marantz CD40, Denon
TU260L,
and Epos ES11 speakers. While I am happy with the performance of the
amplification, I am having problems with the volume settings. Most of my
listening is done with the volume control set at 1 or 2, and with some
newer
recordings, which seem to be recorded at ever higher levels, 1 is too
loud.
The CD input is the standard 300mV version - Assuming I could find one,
would it be worth getting the 500mV option? Or should I use in-line
attenuators or attenuated interconnects between CD player and pre-amp, and
if so, where can I get such items? Is it preferable to use attenuation
between source and pre rather then pre and power?
Any other suggestions?
TIA.

I have a couple of Quad 34's I had the output increased on one so I could
use it with Quad II amps, this was done by decreasing the value of resistors
R118 & R121 and increasing R119 & R122
To reduce output Connect additional resistors in paralle with resistors R119
& R122
470 ohm for 9db .18v
180 15db .09v
100 20db .05v
outputs
1.6v 1.1v 0.775v
R118/R121 shorted 1k 1.5k
R119/R122 3.3k 2.2k 1.5k
I have copies of most service manuals, of Quad kit in psf format, have not
looked but I think it would have a lot more information
