ROOTMASTER EVO II
USER GUIDE
Inputs
There are two choices of instrument input, these are marked passive and
active. The passive input is high sensitivity and high impedance to suit
passive bass instruments. The active input is much lower sensitivity and
impedance to accurately match the signal from active bass instruments
i.e. Those with a built in battery powered pre-amp.
Input control
The input control sets the signal level through the preamp in conjunction
with the input level vu meter. This is adjusted to give a reading of 0vu on
the meter for average playing dynamics with occasional peaks into the
red region. Please note that the setting of this may have to be re-adjusted
after modification of the E.Q. controls.
Shape
With this button in a fixed E.Q. is superimposed on the pre-amp to give a
bass & high boost to the sound. This gives +8db at 50hz and gives +10db
at 10khz.
E.Q.
This button switches the equalisation section in or out i.e. the Bass, Mid-
dle and Treble controls and the two rotary controls placed between these.
