The presence of many connectors makes the receiver more versatile. But there are also narrowly targeted models, the number of connectors which are limited to a certain area of use. And when choosing their own receiver, users need to consider exactly your goals for using the receiver. For extensive connection, Denon AVR-S540BT got 6 points, but Yamaha RX-A780 received 9 points.
Denon AVR-S540BT is equipped with 5/1 HDMI inputs and outputs, and Yamaha RX-A780 has 7/2 HDMI inputs and outputs.
HDMI eARC is the next step in the development of audio return channel technology, which works in conjunction with HDMI 2.1. Using eARC provides the highest sound quality for home audio systems. HDMI eARC is available on Yamaha RX-A780.
The HDCP encryption protocol is now mandatory for most media devices. This security technology encrypts digital signals from one product to another. HDCP content-encryption protocol is present on Denon AVR-S540BT in the HDCP 2.2 version, and Yamaha RX-A780 has the HDCP 2.3 version.
Connecting a vinyl player or phonograph is possible using a Phono input which is represented by mini-jack or RCA connectors. Only the RX-A780 has a Phono interface.
