Brand: Onkyo

The Onkyo T-9090 (mkI) is a high-end integrated amplifier that was released in the late 1980s. It features a power output of 85 watts per channel into 8 ohms, with an additional 25 watts per channel in bridged mono mode. The amplifier uses Onkyo's exclusive Discrete Feedback Circuitry (DFC) technology, which provides exceptionally precise and detailed audio reproduction. The T-9090 also boasts a high-quality toroidal power transformer, and it is known for its rich, full-bodied sound and comparatively low levels of noise and distortion. It is considered a classic among audiophiles and collectors, and it remains a sought-after piece of vintage audio equipment.Here are some additional technical specifications for the Onkyo T-9090 (mkI):- 2-channel integrated amplifier- Selectable input impedance: 10k ohm or 47k ohm- Inputs: 6 pairs of RCA line-level inputs, 1 pair of XLR inputs (unbalanced), and 1 phono input- Outputs: 1 pair of Speak On speaker terminals, 1 set of preamp outputs with RCA connectors, and 1 set of record outputs with RCA connectors- Subwoofer output: 1 set with RCA connectors and variable level control- Tone control: Bass (20 Hz, ±10 dB) and Treble (20 kHz, ±10 dB) controls, with bypass switch- Equalizer: 5-band graphic equalizer with 10 discrete frequencies, with bypass switch- DIM (Dynamic Interlock Modulation): Onkyo's proprietary circuitry designed to eliminate bass-and-treble distortion that can result from overdriving loudspeaker cones at high frequencies- Protection circuitry: Input overload indicators for all inputs, as well as AC fuse and DC protection at the output stage- Dimensions: 435 x 170 x 410 mm (W x H x D)- Weight: approximately 21 kg- Color: silver- Manufactured in Japan.Note: "mkI" in this context refers to the first generation of the T-9090 model, which was produced from 1988 to 1992. A newer version, the "mkII," was released in 1992 and featured some cosmetic and functional improvements.
