Firmware updates via network connection

Perform firmware updates quickly and easily over a network connection.

Built for sound

Every detail from the removable aluminum faceplate, to electronic component selection, special 2nd generation ES solder, structural/chassis elements, and even screw placement has been scrutinized and tuned in the higher interest of reliably consistent sound performance.

The STR-ZA3100ES offers improved structural stability for better sound via the analogue signal path. This circuit is located on a glass epoxy board, in order to achieve higher speed and power.

Three DSPs to reduce unwanted electrical noise

Dispersing the load between three DSPs allow the realization of clarity and realistic ambience by reducing noise.

USB Front Input

Using the front mounted USB, you can easily apply system updates and during setup, save all receiver settings to a flash drive for backing up and porting over to another unit to replicate settings.^3,4

Seamless Integration

With help from your authorized ES dealer/installer the full power of an ES receiver can easily be integrated into expanded home automation systems with all major third-party control partners, simplified IP access via the front panel ‘Ping’ button, A/V zone distribution and simplified setup including built-in test patterns and access to easily used setup features.

In-ceiling speaker mode

Developed especially for use with in-ceiling speakers and easily configured during setup, In-Ceiling Speaker Mode virtually relocates the Front and Center in-ceiling speaker sound images to better coincide with the screen.
