Amplifier
Onkyo TX-SR353 and Onkyo TX-SR343 have 5 channel amplifiers. Onkyo TX-SR353 delivers 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and Onkyo TX-SR343 delivers 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven)
Video Features
Both receivers support 4K passthrough up to 60p. Onkyo TX-SR353 supports HDR10.
HDR10
High-dynamic-range (HDR) video has greater dynamic range than standard-dynamic-range (SDR) video with brigter whites and deeper blacks. HDR10 was announced on August 27, 2015, by the Consumer Technology Association and uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports up to 1000 nits of brightness and 10-bit color which corresponds to 1024 shades of the primary RGB colors.
WRAT
Onkyo TX-SR343 features Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.
Advanced Music Optimizer
Compressed music enhancement in Onkyo TX-SR353 and Onkyo TX-SR343 is done by Onkyo’s Advanced Music Optimizer. While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound. Also included in this technology is a loudness correction feature that further improves the audio character of compressed files.
Phase-Matching Bass Boost
Onkyo TX-SR343 features Phase-Matching Bass Boost. The negative effects of phase-shift or the timing difference between sound waves of different frequencies can sometimes be heard in audio players when corners are cut in order to increase bass response. While most audio systems have some form of low-frequency enhancement system, often a bigger bass sound comes at the expense of mid-range clarity, and results in a smeared or muddy sound. Onkyo’s Phase-Matching Bass Boost technology avoids this problem by improving the phase timing to preserve the natural clarity of the mid-range allowing vocals and strings to shine while maintaining a smooth, powerful bass response at all volume levels.
Connectivity
Onkyo TX-SR353
Onkyo TX-SR353 can also connect to bluetooth devices via built-in bluetooth adapter. It has 4 HDMI inputs with HDCP 2.2 copy protection.
