MARANTZ MODEL 2230
AM/FM STEREO RECEIVER
With impressive
specifications and Marantz-exclusive features, the low-prieced Model 2230
offers more value and performance than any other receiver in its class. It
delivers 60 watts continuous RMS into 8 ohm speakers from 40 Hz to 20 kHz with
total harmonic and intermodulation distortion under 0,5%. Frequency response is
±0,5 dB. Stepped, three-zone controls for Bass, Mid, Treble. Provisions for
tape decks, phones, record changers, 4-channel adaptors. Ultra low-distortion
FET, RF and IF circuitry. Massive heat sinks; automatic protection for internal
circuitry and associated speakers, plus the famous Marantz gold-anodized front
panel. Completely enclosed metal chassis finished in simulated walnut or with
optional WC-22 walnut cabinet.
