AVR 7550HD

This week Harman Kardon announced a new firmware update for three of its receivers - the AVR 2600, AVR 3600 and AVR 7550HD - giving them HDMI v. 1.41 and 3-D capability.

The upgrade will allow compatibility with all 3-D formats from either Blu-ray players or satellite and cable set-top boxes, and all 3-D video displays. Current owners of these AVR models will be able to upgrade their existing AVRs to HDMI v. 1.4a with 3-D. The units will ship with the upgrade already loaded beginning this September.

The free firmware upgrade is available at www.harmankardon.com.Simply download the software to a USB memory stick, insert the stick drive into the front panel USB jack on the AVR unit and use the remote to navigate through on-screen instructions to install the upgrade. No software loader or direct connection between the computer and AVR is required.
