About the TX-8160
The Onkyo TX-8160 Network Stereo Receiver delivers 80 watts per channel into 8 ohms (20 Hz to 20 kHz, 0.08% THD, 2 channels driven) from a high-current analog amplifier with a discrete low-impedance output stage and large power transformer for better speaker control and dynamic range. It features built-in Wi-Fi, Bluetooth, and Apple AirPlay for wireless streaming, with support for services such as Spotify, Pandora, SiriusXM Internet Radio, Slacker, and TuneIn via the Onkyo Remote app for iOS and Android. A 384 kHz/32-bit AKM AK4452 DAC handles digital-to-analog conversion for high-resolution audio playback. Connectivity includes a phono equalizer input for turntable connection, multiple analog RCA inputs, USB type-A port for audio playback from storage devices, Zone 2 pre-outs for distributed audio, and speaker A/B switching with gold-plated headphone jack. An FM/AM tuner with 40 presets and RDS is built in, and direct input enables a purer signal path. Dimensions are approximately 435 x 149 x 345 mm.
