Noise Check - Decware TORIIMONO Owner's Manual

O W N E R S M A N U A L
Summary of quick start up
You're going to hook up your speakers, properly install the tubes and power cord, plug
the amplifier in, turn the volume control all the way down, and turn on the amp.
You'll watch the bias meters as the tubes start to glow and within a minute or less you'll
see them register the current of each output tube. Adjust the control so they match.

NOISE Check

At this point, the amp is on with a speaker hooked to it and the volume is turned all the
way down. This is called "idle" and you should hear no sound from your speakers. No
hum, no hiss, no noise that would be detectable from the listening chair. To hear
anything at all you should have to put your head around 6 to 12 inches away from the
speaker.
Source hookup - it is important from this stage forward to pay attention to the residual
noise floor that we have established in the noise check above. If it increases in any
way as we hook up the source component(s) then we know the cables or source
components are the cause.
The next step is to hook up your source, and this can be done with the amplifier on or
off, but in both cases, the volume control on the amplifier should always be turned
down as far as it will go while you are hooking up the source cables.
If you have balanced sources then use the balanced XLR input jacks, if not, then use
the RCA unbalanced input jack. Once connected, with your source paused, you can
slowly raise the volume control and check for noise. If everything seems satisfactory,
then return the volume control the off position, and un-pause your source and slowly
raise the volume to the desired level.
