Brand: DENON
Model: PMA-780D
Year: 1987
The PMA-780D was a completely new type of integrated amplifier equipped with a digital multi-interface circuit and a D/A converter circuit that directly receives music information sent from CDs, DAT, DBS (PCM satellite broadcasting), etc. as digital signal. This unit is equipped with 3 digital input circuits and automatically selects the sampling frequency of CD, DAT, and DBS. Furthermore, it is equipped with a double super linear converter circuit that uses a high-precision digital filter and independent D/A converters for left and right channels, converting it into a pure audio signal and directly driving the power amplifier. The amplifier section is equipped with a super non-feedback power amplifier that boasts high speed, and a pure dynamic power circuit that uses a powerful power transformer, dramatically improving instantaneous power supply capability and delivering unwavering high dynamic power of 350W + 350W/2Ω. Furthermore, it is equipped with a wealth of functions such as a phono equalizer amplifier, a processor loop, and three recording/playback terminals.
