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.
