The RX-V577 AV receiver provides advanced HDMI features including pass-through of 4K Ultra HD, which is gaining popularity. 4K Ultra HD refers to four times the resolution of a 1080p display. This receiver is capable of passing the 4K Ultra HD data from the source to the monitor, for image clarity far beyond present standards. It is designed with a strong focus on achieving exceptionally high sound clarity. The RX-V577 employs a discrete amp configuration and a low jitter PLL circuit, which contributes to its excellent audio performance.

Wi-Fi built in capability allows wireless connection with your household wireless router, greatly simplifying system connections to enjoy network audio and music streaming services. If no Wi-Fi router is available, the unique Wireless Direct feature not only allows you to stream music directly from your smartphone or tablet via AV Controller App's Music Play feature, Apple AirPlay etc., but also control your receiver using the AV Controller App.

A benefit of HDMI is the availability of CEC functionality. When the unit is connected to a CEC compatible TV, it will turn on and off together with the TV, and you can use the TV remote to control the volume. CEC also provides advanced functionality with other components. For example, you can use the receiver’s remote unit to control player functions like skip and stop.
