MASTER EQ. FILTER
he MASTER section is fitted with a 4-position pot called FILTER , with which it is
possible to change the EQ of the MIX L&R signal from the mixer’s input channels.
The three pre-set EQ curves enable the response of the system to be varied according
to the type of use or to suit personal taste.
• 0 OFF é In this position, the filter doesn’t modify the MIX L&R signal in any
way.
• 1 WARM é This curve has been designed for all applications in which a warm,
embracing sound is necessary. In fact it “cuts away” the signal in correspondence
to those frequencies which one typically tends to remove on single channels ( mids )
and boosts the frequencies at the extremities of the band ( low and high ).
• 2 VOCAL é The VOCAL curve has been designed for use in all those
environments or situations in only the human voice has to be reinforced: conference
rooms and meeting halls, theatres, churches, etc. The response curve is
characterized by a bandpass filter, used to reduce low frequency resonance which
often occur when using microphones, emphasize the mid frequencies typical of the
human voice and reduce the high-frequency feedback problems.
• 3 LPS - P.A. SYSTEM é This third curve has been specifically designed for
compensating and optimizing the response of the LEM range of LPS PLUS & LPS
ACTIVE loudspeaker enclosures.
