AMP SERIES
Functions & controls
9
GND
Auxiliary connector for the earth of the amplifier.
10
GROUND ON / FLOATING
Controls the separation of the electrical earth from that of the
chassis. Using this selector, it is often possible to break earth
loops which can form when several units are connected together
and which can cause hum or other noises
LIMITER ON/OFF
Limiter ON/OFF selector.
PARALLEL/STEREO/BRIDGE selector
Selector for the amplifier’s 3 operating settings: allows to
decide how to use the amplifier in the audio setup, considerably
simplifying the connections with other units (crossovers, other
amplifiers, loudspeaker enclosures).
This control should only be used when the amplifier is off,
otherwise the loudspeakers’ components could be damaged.
A) STEREO
With the STEREO setting, 2 separate signals are treated separately
by channels A and B of the amplifier.
