Pioneer SC-LX502 vs SC-LX501 Review

The SC-LX502 and SC-LX501 are mostly identical, except for the fact that all 6 rear HDMI inputs on the SC-LX502 are full-bandwidth (in terms of the HDMI 2.0 specification). Furthermore, the aforementioned inputs are HDCP 2.2 compatible. In comparison, only 3 of the 6 rear HDMI inputs on the SC-LX501 have enough bandwidth to transmit 4K signal at 50/60Hz with full chroma 4:4:4 and 8-bit color depth (12-bit color depth is possible when 4:2:2 or 4:2:0 chroma subsampling is used). HDCP 2.2 is only supported on HDMI IN 1-3 on the SC-LX501 while HDMI IN 4-6 are compatible with HDCP 1.4. The latter three HDMI inputs have limited bandwidth which also applies to the single HDMI input that can be found at the front of the SC-LX501. There is no difference in that aspect between the SC-LX502 and SC-LX501 since the front HDMI input on the SC-LX502 also has limited bandwidth. It should be mentioned, though, that the SC-LX502's front HDMI input is compatible with HDCP 2.2 unlike the SC-LX501's front HDMI input which supports only HDCP 1.4.

The SC-LX502 supports HDR10, HLG (Hybrid Log-Gamma), and Dolby Vision signal pass-through out of the box on all of its rear HDMI inputs. The SC-LX501, on the other hand, supports only HDR10 out of the box. When it comes to Dolby Vision pass-through, you'll have to install a firmware update via USB before you can transmit Dolby Vision signal. Furthermore, only HDMI In 1-3 can be used for connecting an Ultra HD Blu-ray player to the SC-LX501. Whilst on the subject of firmware updates, the SC-LX501 needs one for DTS:X whereas the SC-LX502 supports this object-based audio format out of the box. In order to use FlareConnect, which is a multi-room audio system, you'll need to perform a firmware update on either the SC-LX502 or SC-LX501. Additionally, you'll need other FlareConnect compatible components (such as speakers or a receiver that are sold separately) so that you can wirelessly send music to. The music selection and destination is done in the Pioneer Remote App. There is no difference in the number or the type of external audio inputs on the SC-LX502 or SC-LX501 that can be used with FlareConnect.

The power amp section is identical on the SC-LX502 and SC-LX501. Both receivers are rated at 120 Watts per channel (2 channel driven into 8 ohms loads at 1 kHz with no more than 0.08% THD). A Class D3 (Direct Energy HD) Amplifier provides 7 amp channels on both the SC-LX502 and SC-LX501. Up to two powered subwoofers are supported, but the SC-LX502 and SC-LX501 lack discrete subwoofer functionality, meaning the same signal is output from the two Subwoofer pre out jacks. There are two pre/line outs for Zone 2, meaning you can use an external 2 channel power amplifier in order to have a stereo in another room while the SC-LX502 and SC-LX501 built-in amplification powers a 7.1 channel speaker system in your main room. Since there are 9 speaker terminals on the SC-LX502 and SC-LX501, it's possible to connect both height and surround back speakers. However, they cannot be powered simultaneously so a Dolby Atmos speaker setup of only up to 5.1.2 channel is supported (5.2.2 channel if two powered subwoofers are used). The SC-LX502 and SC-LX501 lack any dedicated pre-outs for the purpose of expanding a Dolby Atmos setup via an external amplifier.
