For over three years
the Marantz 2270 was the standard by which all others compared their receivers.
Now, its successor, the 2275 carries that comparison one step futher. The 2275 boasts of a Phase-Lock-Loop FM Multiplex
Demodulator to assure maximum separation with
a minimum of distortion. The Multipath Indicator tells you the best
position of your FM antenna. The Variable Turnover Tone Controls provide a
flexibility for contouring the sound that is far superior to anything
previously available. Plus, there's a unique Dolby De-emphasis Switch for use
with an external adaptor - to accommodate Dolby FM broadcasts. There are
complete facilities for two tape recorders with the ability to "dub"
from either one to the other. And the pre-out main-in jacks permit convenient
use of any external device such as an equalizer or electronic cross-over. The
direct-coupled full complementary amplifier output circuitry assures crystal
clear highs and solid lows. The entire package is backed up with a full three
year parts, labor and performance guarantee.
A full Complement of Inputs and Outputs
In
addition to the standard phono and auxiliary inputs, two sets of tape inputs
and outputs are provided to facilitate copying from one tape deck to another.
Front panel dubbing jacks allow you to add a third tape deck without disrupting
any rear panel connections.
The
preamp-out/main-in jacks on the rear panel enable you to use the preamplifier
and amplifier sections independently. You get simplified connection of external
components such as noise reduction systems, equalizers and electronic
crossovers - and the ability to use the receiver's preamp section to drive a
separate power amplifier. Here's
another benefit: Connecting the preamp section directly to a tape deck enables
you to make specially equalized recordings by using the preamp's flexible tone
controls.
