8. OUTPUTS
Power out : outputs to be connected to the loudspeaker enclosures. Amplifier's A&B outputs
both have BINDING-POST connectors and speaker connectors
Only loudspeaker(or loudspeaker enclosure systems)within the amplifier's
declared power and Impedance load range should be connected to the
amplifier's outputs (see Technical pecifications). Use only speaker cables
(two-core cables, normally with a red and a black wire):do not use screened
of "signal" cables (cables normally used for microphones , instruments and
audio equipment in general).
9. 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 of other noises.
10. STEREO/BRIDGE selector
Selector for the amplifiers 2 operating setting: allows to decide how to use the amplifier in
the audio setup considerably with other units (crossovers, other amplifiers, loudspeaker
enclosures).
This control should only be used when the amplifier is off, otherwise the
loudspeaker's components could be damaged.
A) STEREO
With the STEREO setting, 2 separate signals are treated separately by channels A and B of the amplifier. In
other words, a signal connected to input A is only treated by channel A of the amplifier and only fed to
output A and a signal connected to input B is only treated by channel B of the amplifier and only fed to
output B..
B) BRIDGE
With the BRIDGE setting signal is amplified by the two sections (A&B) of the amplifier
summed together. In other words the signal connected to input A is:
1)amplified by both the amplification sections summed together;
2)fed to a single output (BRIDGE).
The characteristic of this setting consists in the fact that there is a signal fed out with
double the power and rated impedance ( see TECHNICAL SPECIFICATIONS ).
11. INPUTS
Balance inputs (0 dB/30 k ): in all models both channel A&B of the amplifier have a
double balanced input with an CANNON connector and a JACK connector connected in
parallel. In this manner, the amplifier s input signal can be connected to either of these
connectors (greatly facilitating connections) and if necessary, can be passed on to the
input of another amplifier or other units (see illustrations).
