Sony’s STR-DH770 is one of the least expensive 7-channel receivers you’ll see on store shelves. Despite this, the 770 comes loaded with a substantial list of features such as 4K support, Bluetooth, and more.
Sony STR-DH770 Connectivity
The Sony STR-DH770 is a 7.2 channel receiver, which according to the spec sheet, puts out about 145 watts per channel. To connect all of your components, the 770 has 4 HDMI inputs and 1 output. If you have a 4K TV or plan on getting one, then the STR-DH770 should play nice with it. All of its HDMI inputs and outputs support HDCP 2.2, 4K at 60p 4:4:4, and HDR (High Dynamic Range). The receiver will pass through a 4K signal, but it won’t upscale regular HD Video to 4K quality.
If you need a few legacy connections, the 770 also supplies 4 analog audio inputs and 2 digital inputs (1 coaxial and 1 optical). The front of the amp includes a headphone connection so you can listen to your music without disturbing others in your house. A USB input rounds out the 770’s list of connections.
The 770 does not include built-in WiFi, however, it does support Bluetooth. With Bluetooth, you can wirelessly stream audio from your smartphone, computer, or tablet directly to the AV receiver.
The Sony STR-DH770 is capable of decoding Dolby TrueHD and DTS-HD Master Audio. The amp won’t decode Dolby Atmos or DTS:X. On the music front, MP3, AAC, WMA, WAV 192k, FLAC 192k, ALAC, and AIFF are all supported by the 770. Simply plug your drive into the front USB port and the receiver will do the rest.
To assist with maximizing the sound quality of your system, the Sony STR-DH770 includes an auto-calibration suite. Plugin the included microphone and the receiver will send out a series of test tones which it uses to set the appropriate frequency crossovers and speaker levels for your home theater. If you’re facing speaker placement challenges, the Sony 770 can also approximate surround sound with only two front speakers. Other manufacturers also employ similar features on their amps and it’s usually hit or miss. However, it does typically create a wider and more dynamic sound stage
Sony has given the STR-DH770 an extremely competitive price point. In fact, you’ll be hard-pressed to find a more affordable 7-channel amp. However, don’t let the low price fool you. If the 770 sounds nearly as good as its more expensive brethren then it’s well worth a look.
