Additionally, built-in Bluetooth for wireless audio streaming and a rear-panel USB for hi-res and lossless digital music, make the value of this receiver enormous. A powerful, versatile, and easy-to-use hub for all your media sources, the TX-SR333 is the ideal entry point to exhilarating entertainment.

Supporting Next Generation HDMI 2.0

Imagine playing the latest blockbuster game or movie on your Ultra HDTV at a breathtaking 60 frames per second. Now add thunderous 5.1-channel surround sound from Onkyo. With every HDMI terminal on your receiver supporting HDMI 2.0 4K/60 Hz, all this and more is possible. Even if you're not planning on upgrading your current display right away, it's good to know your Onkyo receiver is ready for the future of gaming and video entertainment.

Built-In Bluetooth

The TX-SR333 has built in Bluetooth 2.1 + EDR with DSP optimization for wireless audio streaming from your smartphone or PC. No wires, no dongles, no mess. Just pair your Bluetooth-capable device and stream directly to your home theater. With Advanced Music Optimizer DSP compensating for compression, music via Bluetooth sounds better than ever.

Authentic High-Fidelity Amplification

Onkyo's Wide Range Amplifier Technology (WRAT) is designed for high current delivery. High instantaneous current is needed to maintain control of the speaker drivers for precise yet musical audio reproduction, from delicate piano passages to the thunderous roar of an action movie soundtrack. Backed by a massive high-output transformer, the amplifiers feature a discrete low-impedance output stage with high-current transistors for instantaneous power and very low distortion. The resulting sound is detailed, dynamic, and highly realistic for both stereo and multichannel listening.

High-Res Audio Processing

There's nothing quite like plunging into a high-resolution studio-master 5.1-channel movie soundtrack.Your TX-SR333 can decode and play Dolby® TrueHD and DTS-HD Master Audio™formats via HDMI for a thrilling surround-sound experience. A 32-bit DSP chip and high-quality 192 kHz/24- bit TI Burr-Brown DAC smoothly and efficiently decode all the lossless and high-resolution formats common to DVD and Blu-ray.

Play Lossless and Hi-Res Music via USB

If you prefer a wired connection, the rear-panel USB port is ready to accept a range of audio formats from mass- storage class disks. As well as MP3 and AAC, you can play FLAC and WAV up to 192 kHz/24-bit resolution, Apple Lossless and 5.6 MHz DSD. Alternatively, you can connect your PC, smartphone, tablet, or media player via the digital or analog audio inputs.

Zone 2 Line-Out for Multi-Room Audio

The Zone 2 line-level output lets you enjoy music from the source devices connected to your A/V receiver via the analog audio inputs in another area of your home. If you have a power amp and a pair of speakers, you can set them up in your kitchen, garage, or even out on the deck and listen to CDs and radio playing via your A/V receiver.
