Never until now has a line of stereo
receivers packed so much muscle and
so little distortion.

The Marantz 2252 produces a mini-
mum continuous power output of 52
watts per channel, with no more than
0.1% total harmonic distortion, from 20
Hz to 20 kHz, both channels driven into
8 ohms.

Under the same conditions, the 2238
delivers 38 watts per channel, with no
more than 0.1% total harmonic distor-
tion. The 2226 delivers 26 watts per
channel, with no more than 0.3% THD.
And the 2216 delivers 16 watts per
channel, with no more than 0.5% THD.

Whichever Marantz receiver you
choose, you get the same technical ex-
pertise and uncompromising standards
of excellence that made Marantz the
worlds most respected name in high
fidelity.

A Marantz may cost more than an
ordinary stereo receiver. But thats be-
cause we put more quality into a
Marantz. And it's because a Marantz is
designed to continue to meet its speci-
fications through years of steady per-
formance.

You dont just buy a Marantz, you
invest in it.

symmetry OIIIIIIII

Every Marantz receiver features a full
complementary symmetry output stage
-the same design used extensively in
Marantz professional components. Its
more costly than the quasi-comple-
mentary outputs of many receivers. But
it assures significant performance im-
provements in linearity and harmonic
and intermodulation distortion over oth-
er types of output stage circuitry.

The Marantz output stage design also
produces an exceptionally wide Safe
Operating Area - that range where
voltage, current and temperature con-
ditions permit reliable output stage op-
eration. The result is an amplifier sec-
tion so stable, it will drive a load at
virtually any frequency or level without
breaking down.

Output devices and speakers are
guarded by a sophisticated energy-
sensing protection circuit, which elimi-
nates distortion caused by the tradition-
al protection circuitry used in ordinary
receivers.

Early transistorized power amplifiers
incorporated either a transformer or a
capacitor between output stage and
speaker terminals. However necessary
this was for adequate output-to-speak-
