considerations can be said for the treble phase

switch at 0º (continuous line) and 180º (dotted

plane of the mid and treble engines. The start
position is with the switch at 180º. If a disco
sound or a lower voice enhancement are desired,
place the switch at 0º.
BASS BOOST
emphasizes by 3dB the bass output. The normal
position for the 90% of the situations is off
(unpushed). Only if the bass cabinet is not
stacked to the EPC215B is placed far from walls
(eg. hanged) is recommendable the use of this switch.

4.3. Machines connected to the processor

External equalizers must be used with care because the EPC200 already does a
pre-equalization and is possible to feed excessive energy to the system thus yielding to an overload.
The processor has been designed to give an equilibrated sound. Any external equalization should be
limited to ±6dB, more than enough to compensate possible hall and/or equipment deficiencies.
However, if a mixer with +15dB tone control is used, make special attention to possible saturation
of the system by checking the processor overload indicators (3-4-5).

5. CONSIDERATIONS

5.1. Ground loops

Be always sure that all the signal sources connected to the processor do not have their
grounds interconnected between them. The cable shielding, when connected to the chassis, can
never be interconnected between them. If after all, there is still noise, use the GROUND LINK
switch (19) so that electrical and mechanical grounds will be disconnected.

5.2. Audio connections

As a general rule, make the signal connections as short as possible and use the best
connectors and cable available. Cables and connectors are frequently undervaluated, forgetting that
a bad connection can result in a poor sound reproduction.
