Onkyo TX-850

Important Features:

Discrete Output Stage:

Instead of IC power amp circuitry, the TX-850 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 proof of Onkyo's dedication to audio excellence not merely in its high end amps but across the board.

"CD Direct" Switch:

This switch lets the user bypass the tone and balance controls in the amplifier when listening to CD (or other digital audio sources).since noise levels in digital audio are extremely low, sending and switching the audio signal through tone and balance circuitry is often unnecessary and may even adversely alter the high quality digital signal.

APR (Automatic Precision Reception) System:

Onkyo's exclusive APR precision reception system lets every FM broadcast sound its best. Intelligent circuitry monitors the signal and selects the optimum settings for three reception modes: stereo/mono, hi-blend on/off and local/DX mode, the system controls the noise reduction on/off mode as well.  The APR system settings are shown by indicators on the front panel.
