The Carver
Receiver
When Bob
Carver designs a receiver you can be sure it is like no other. To give you the
power you need for today's recording advances plus virtually noise-free stereo
FM reception. Carver has designed a receiver with astonishing performance. This
extraordinary instrument incorporates two of the high fidelity art.'s most
advanced technological breakthroughs: Bob Carver Magnetic Field Power Amplifier
and his Asymetrical Charge Coupled FM Detector.
With the
Carver Receiver you command 130 watts per channel and fully digital quartz
synthesized AM-FM stereo tuner through a highly sophisticated and meticulously
engineered premplifier section.
Live music
is full of lighting-fast transients, combinant crests of demand created by
multiple music waveforms and high intensity peaks. To reproduce the full sound
of the music now made possible by the most recent recording advances in fine
analog recordings and especially Digital Audio Discs, your system needs large
amounts of power to accomodate the dynamic range without distortion.
The Magnetic
Field Amplifier in the Carver Receiver gives you 130 watts per channel of pure
clean power so you can truky appreciate the music.
The
technological elegance of the Magnetic Field Amplifier enebles it to produce
large amounts of power without the need for heavy heat sinks, massive
transformers, and enormous power capacitors required by conventional amplifier
design.
Unlike
conventional amplifiers which produce a constant high voltage level at all
times, irrespective of the demands of the ever-changing audio signal and indeed
even when there is no audio signal in the circuit at all the Magnetic Field
Amplifer's power supply is signal responsive and highly efficient. It produces
exactly and only the power needed to carry the signal with complete accuracy
and fidelity.
The Carver
receiver gives you FM stereo performance unmatched by that of any other
receiver.
As it is
transmitted from the station, the stereo FM signal is extremely vulnerable to
distortion.noise, hiss and multipath interference. In fact because of the
transmission system in use today the signal to noise ratio of FM stereo has
been degraded fifteen times (more than 23 dB).
However,
when you engage Carver's Asymetrical Charge Coupled FM Detector circuit, the
stereo signal arrives at your ears virtually noise-free. You hear fully
separated stereo with space depth and ambience.
You will
also appreciate the AM section. Meticulous attention to every aspect of tuner
performance gives you an AM section with true high fidelity response. You will
not find another receiver with such high performance anywhere.
The Craver
Receiver has been designed for serious music listeners who seek fidelity
accuracy and musicality.
