Definition of the M-4.0t Amplifier: The CARVER M-4.0t is a stereo Magnetic Field Power Amplifier which incorporates CARVER's patented technology. This technology is utilized to create a powerful, highly efficient amplifier. Above all, the M-4.Ot duplicates with extreme accuracy, the sonically pure characteristics of the Silver Seven Vacuum Tube Reference Amplifier.
The cool techie stuff:
Magnetic Field Theory
The Magnetic Field principle itself enables a compact, lightweight power supply to process large amounts of energy, and to store energy reserves in a unique. highly efficient way. Large supply capacitors are not needed, and a bulky expensive power transformer of the conventional sort is not reduired.
The Magnetic Field Amplifier's Power supply is governed by electronic control circuits that directly respond to the moment-to-moment power requirements of the audio sections.
The AC power control circuitry controls the amount of power the Magnetic Field coil must store and transfer. The AC power control receives its instructions from the power demand sense circuitry which are transierred to the primary via the optocoupler. For low power demands. conduction begins near the minimum voltage points for the AC line signal, and is relatively brief in duration. As more drive becomes needed, conduction begins earlier and lasts longer.
The employment of High, Mid and Low DC power supplies permits biasing the output stage ol the low power AMP to near class "A". Much less power is dissipated at low output levels while providing higher DC power supply voltages when higher amplification is required. Accordingly, the M-4.0t dissipates little of the energy it processes as heat. The CARVER M-4.0t Amplifier's power supply is modulated on a signal-demand basis. It uses Low, Mid and High DC power supply voltages combined with Low, Mid and High power amplification stages to increase your Amplifier's power from a 35 watt amplifier into a 400 plus watt-per-channel amplifier. The result is high efficiency, with large output capability.
Amplifier Protection: This unit incorporates a main fuse along with specifically designed protection circuits to protect the amplifier and loudspeakers
