Stereo Integrated Amplifier (1988)
The Pioneer A-91D has high driving capacity, suitable for low-impedance speakers.
Use of the Non-switching Circuit Type III reduces distortion for a high-quality playback sound.
The line direct circuit allows for high-fidelity reproduction of sources, with flat frequency characteristics and little tone variation, while the REC selector switch makes tape editing easy.
The unit has a built-in phono equalizer circuit, permitting use of an MC cartridge.
High-quality parts for an outstanding sound reproduction honeycomb chassis, honeycomb heat sink, large insulator, large speaker terminals, CD and Phono gold-plated input terminals, etc.
