2. How to use it:

Read this owner manual completely before use to fully understand your Shiva's functions. In paragraph e)
th
the differences of the 20
a) Master Volume and Presence
The Master Volume and Presence work on both channels. Experiment with different combinations
between Volume and Master Volume. You can set the Volume high and the Master Volume low or set the
Master high and the Volume low. One setting could be just as loud as another, but they will feel and
sound different.
b) Boost Function and Bright Switch
On Channel 1, with the Boost engaged, the Tone-Stack is bypassed. This means the Bass and Treble
controls are not in the circuit anymore and have no effect on the sound. This was the only way to have a
boost function on this channel with the original un boosted tone preserved.
With the Bright switch pushed in you get a brighter more open sound; this is less to none effective the
higher the Vol.1 is set.
On Channel 2, with the Boost off use Vol.2, with the Boost engaged use B.Vol.2. This makes the boost
variable and you are able to set it quite different.
With the Bright switch pushed in you get a brighter more open sound. This gets less effective the higher
the Gain is set but still noticeable if turned all the way up.
