SYSTEM CONNECTION
Speaker output terminals are on the rear panel. The terminal under the label “COM” is COMMON. The
terminals under the labels “4
Ω
, 70V, 100V” are Hot. The connection should be COM-4
Ω
/ COM-70V /
COM-100V.
Normally the “rated power” (70V / 100V) output terminal is used in output connection. The connected
speaker should have a matching transformer, and the gross power of speakers should be less than the
rated power of the amplifier.
“Rated Impedance”(4
Ω
) output terminal can be used when speakers are fixed closely, and the gross
impedance of speakers should be 4
Ω
.
