Note on loudspeaker impedance:
The power ratings specified for this Marantz receiver are obtained using
fixed value test load impedances. However, the actual impedance of a
loudspeaker system will vary with frequency, deviating from the nominal
rating. This Marantz amplifier will drive any modern loudspeaker system
with a rated impedance of 8 ohms or higher. A few newer loudspeakers
feature impedances of less than 8 ohms. The high current output capability
of this Marantz receiver can provide the additional power necessary to
drive such low impedance speakers. However, during extended passages
of high volume, the protection circuitry may temporarily interrupt opera-
tion. If this occurs, simply reduce the volume accordingly. The protection
circuitry is specially designed so that it cannot affect the sound quality
during normal operation.
