Our take on the Sony STR-DE345


Receivers: Your ticket to sensational sound

Your receiver powers your speakers and lets you connect and select your entertainment sources. But a great receiver does a lot more — it ignites your emotions. From the passion of a favorite musical artist, to the crossfire of a super-charged movie soundtrack, to the intensity and immersion of a fast-paced video game, your receiver is the key to experiencing and enjoying it in full.

The power of multichannel surround sound is waiting for you on nearly 12,000 movie soundtracks and many stereo TV broadcasts. The STR-DE345 has the Dolby® Pro Logic™ decoding you need to unlock it. This smart Sony also has 5.1-channel inputs for connecting a Dolby® Digital decoder or DVD player with built-in decoding.

With 100 watts per channel in stereo mode, or 100 watts x 5 in home theater mode, you get the multichannel power you need for sonic clarity, realism, and impact. Speaking of realism, the 'DE345's built-in Digital Signal Processing includes Digital Cinema Sound™ — exclusive soundfield circuitry based on acoustic measurements made at Sony Pictures Studios movie production stages. You'll hear movie soundtracks the way the producers and directors intended!
