Hiya, im looking to use my 840a as a power amp & it has a 'fixed input mode' function but i'm not sure if this actually bypasses the pre-amp or not?
You can set 'fixed mode' at any level so i assume not
The manual says:
"Completely separate pre-amp and power amp toroidal transformers and circuits make the 840A effectively a pre and power amplifier combination in one chassis"
"The 840A features separate transformer secondaries for left and right
channels, twin rectifiers and separate PSU's for dual mono operation of the
left and right power amplifiers. A separate transformer supplies the preamp
making the 840A effectively a Pre and Power amp combination in one box"
"Fixed level inputs
Any input of the 840A is able to be set for fixed gain. Whenever this input
is selected the gain will automatically go to this value and will not be
adjustable by the volume control. This feature allows the 840A to be
effectively used as a stereo power amplifier (for that selected input only)"
Im basically looking to use my DAC as the pre-amp, 840a as power amp, as i hear this will improve sound quality, but i can't see it improving anything unless the 840a's pre-amp is actually bypassed in 'fixed input' mode?
Thanks in advance for any help
