The bass and treble controls use click-stop attenuators with selectable turnover frequencies (200Hz/400Hz for bass; 2.5kHz/5kHz for treble). This allows for highly precise room and speaker correction.
The amplifier boasts an advanced layout, featuring two separate transformers and dedicated power supplies for each channel. This design minimizes channel crosstalk and provides massive current headroom, allowing it to drive difficult speaker loads with ease. pioneer sa 8900 ii
The SA-8900 II delivers a sonic presentation that characterizes the best of vintage analog gear without the sluggishness often associated with lesser mid-fi units of the era. The bass and treble controls use click-stop attenuators
The preamplifier, particularly the phono stage, is a standout feature. Many modern amplifiers treat the phono stage as an afterthought, but not Pioneer. The SA-8900 II features a built around a "first stage differential, 3-stage direct connection, final stage class A operation" circuit. Pioneer went to great lengths here, using premium components like nichrome evaporated metal film resistors with a tolerance of just ±1% and low-loss styrol capacitors with a tolerance of ±2%. This meticulous design results in a phono stage with a maximum allowable input of 300 mV, a very high figure that provides a huge dynamic margin and prevents overload, even with high-output cartridges. This design minimizes channel crosstalk and provides massive
