Installations 6 Matica 500/900 Reference Manual C HAPTER 2 I NSTALLATIONS Unpacking and Inspection Carefully unpack the amplifier and inspect it for physical damage originating in shipping. Do not discard the packing materials; they may be helpful in shipping the amplifier when it is not mounted in a rack or other enclosure.
Installations Matica 500/900 Reference Manual 7 Electrical Installation One of the most important considerations for proper installation and operation of a power amplifier is the capacity of the line feeding the mains voltage to the amplifier.

Installations 10 Matica 500/900 Reference Manual multiple loudspeakers or systems to any amplifier, care should be taken that the actual load impedance does not drop below the amplifierÕs rated output load.
Installations Matica 500/900 Reference Manual 11 Banana plugs are inserted in the ends of the plastic insulating nuts on each output terminal. The terminals are spaced to accept standard 3/4Ó (19 mm) spaced dual banana plugs. Alternately, the insulating nuts may be loosened so that stranded or solid wire may be attached.
Installations 12 Matica 500/900 Reference Manual What we're doing here is compensation for the fact the Matica's B Channel is normally internally inverted and then re-inverted at its output. This improves the amplifier's ability to respond to high power low frequency signals better than conventional amplifiers.
