Features
a
®@ Plenty of Clean
Power
TX-890: 125 watts of continuous power per channel into 8 ohms with no more than
0.02% total harmonic distortion (FTC).
(2 x 380 watts dynamic power at 2 ohms.)
TX-870: 105 watts of continuous power per channe! into 8 ohms with no more than 0.025% total harmonic distortion (FTC).
(2 x 310 watts dynamic power at 2 ohms.)
These tuner amplifiers are designed to consistently deliver their full rated power even into ow impedance loads.
® Discrete Output Stage
Instead of IC power amplifier circuitry, the TX-890 and TX-870
both employ a discrete output stage for effortless drive into low impedance
loads. Low distortion linear switching and the high quality parts used throughout are further proof of Onkyo's dedication to audio ex-
cellence not only in our high end amps but across the board.
@ "CD Direct" Switch
This switch fets you bypass the tone and balance controls when listening to CD players (or other audio sources). Since noise levels in
digital audio components are extremely low, tone and balance circuitry or excessive switches are often unnecessary and may even adversely
affect the sound.
® APR (Automatic Precision Reception) System
Onkyo's exclusive APR system lets every FM broadcast sound its best. A microelectronic brain monitors the broadcast signal and selects
the optimum settings for four reception modes: stereo/mono, hi-blend on/off, local/DX and noise reduction on/off. The APR system
settings are shown by indicators on the front panel.
