SPECIFICATIONS
NOTE:
Measurements
referenced
to
8
ohms
are
taken
with
the
Speaker
Impedance
Selector
set
to
“8
ohm
(High)””.
Measurements
for
4
and
2
ohms
are
taken
with
the
impedance
selector
at
‘’4
ohm
(Normal)”.
Specifications
are
measured
in
accordance
with
EIA
Standard
RS-490
(IHF
A-202)
for
amplifiers
and
ANSI-IEEE
Standard
185
(1975)
(IHF
T-200)
for
tuners.
Tuner
sensitivity
is
measured
via
75
ohm
coaxial
input
and
converted
to
equivalent
300
ohm
values.
