MartinV56 834 Publicado Septiembre 21, 2017 Share Publicado Septiembre 21, 2017 Why auto-transformer? The impedance response of a speaker is rarely flat. The impedance typically rises toward higher frequencies and decreases at lower frequencies. Depending on the impedance, the need for amplifier power varies, and this must be somehow taken into account at the amplifier end, and compensated. Auto-transformers always align the load impedance so that the amplifier outputs more or less the same amount of power independent on the impedance. Thanks to their auto-transformers, McIntosh transistor amplifiers, up from the model MA-6600, do not need to worry about fluctuations in the speaker’s impedance response. Auto-transformers always align the load impedance so that the amplifier outputs more or less the same amount of power independent on the impedance. This is good news, and can cause headache only if the speaker is manufactured assuming that amplifiers are not capable of handling impedance variations at the speaker end. The MA-6600’s got a two-stage output stage: a differential voltage amplifier is connected to a push-pull power amplifier and from there to auto-transformers. As always in McIntosh amplifiers, the power supply is regulated, has a massive power transformer and enough of filter capacitance (100 Jules). The MA-6600 delivers power up to 200 watts (8 Ohms) at 0.005% total harmonic distortion. The Power Guard circuit monitors the input and output signals and dynamically adjust the input signal level so that the amplifier is not overridden into distortion. Further, the circuit protects the amplifier from excessive temperature variations, and impedance matching problems. If there’s anything worry-some, the front panel indicator light remains on and the device is muted. https://www.inner-magazines.com/audiophilia/mcintosh-ma-6600-integrated-transistor-amplifier/ Citar "What this country needs is a good 5 watt amplifier." - Paul Klipsch Enlace al comentario Compartir en otros sitios More sharing options...
