Accuphase A-48 Class A Stereo Power Amplifier

Description: Accuphase A-48 Class A Stereo Power Amplifier AC100V From Japan DescriptionThe A-48 is a full-fledged "pure class A stereo power amplifier" that has been redesigned based on the design technology developed for the higher-end model, and has been refined to have an attractive sound quality. The output element uses high-performance audio-grade power MOSFETs, and is driven by 6 parallel push-pull pure class A per channel. This allows the amplifier output to have a low impedance, and constant voltage drive is possible to support low impedance loads, achieving linear power against the load impedance of 45W/8Ω, 90W/4Ω, 180W/2Ω, and 360W/1Ω (music signal only) per channel. The input circuit also uses an "instrumentation amplifier" configuration. This method configures the entire power amplifier, including the signal input stage, as a balanced amplifier, and the signal path from the input terminal to the power amplifier stage is fully balanced. Thanks to the excellent technology inherited from the higher-end model, a signal-to-noise ratio of 117dB and a damping factor of 800 have been achieved. Furthermore, by using two A-48s in a bridged connection, you can upgrade the amplifier to a high-output monophonic amplifier of 180 W/8 Ω, 360 W/4 Ω, or 720 W/2 Ω (music signal) per channel. ■Power MOSFET 6-parallel push-pull circuit■Linear output characteristics to load impedance■Powerful power supply with large toroidal transformer and large-capacity 60,000μF filter capacitor■Instrumentation amplifier■Signal input section with high-gain discrete configuration■Equipped with dedicated power supply for signal input section■Equipped with line input terminals and balanced input terminals■Polarity switching function for balanced input terminals■Equipped with MCS+ circuit■Equipped with current feedback amplifier circuit■Uses MOSFET switch for protection circuit■High damping factor: 800■Uses balanced remote sensing■Equipped with speaker output protection circuit to prevent short circuit accidents■Equipped with high-sensitivity large power meter■Equipped with two large speaker terminals■4-stage gain control function■Bi-amp connection and bridge connection possible■Aluminum hairline finish top plate Rated continuous average output (between 20 and 20,000Hz)Note: (※) loads are limited to music signals.
