0 Plenty of Clean Power

Tx-seo: 125 watts oi 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.)

TXA87O: 105 watts of continuous power per channel 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 lull rated power even into low impedance loads.

0 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.
0 "CD Direct" Switch

This switch lets 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 on necessary and may even adversely

aflect the sound.
0 APR (Automatic Precision Reception) System

Onkyos exclusive APR system lets every FM broadcast sound its best. A microelectronic brain monitors the broadcast signal and selects
the optimum settings for tour reception modes: stereo/mono, hl~blend on/off, local/DX and noise reduction on/ofl. The APR system

settings are shown by indicators on the front panel.
