INTRODUCTION 

 

The tvONE 1T-DA-674 and tvONE 1T-DA-678 HDMI Distribution Amplifiers provide 
multiple outputs from a single HDMI input for distribution to devices capable of receiving 
and/or displaying such signals. The 1T-DA-674 provides 4 HDMI compliant outputs and 
the 1T-DA-678 provides 8 HDMI compliant outputs.  Each product in this series is 
compatible with HDMI v1.4 specifications; a cutting-edge technology that supports Deep 
Color (10-bit and12-bit) video. In addition, all devices exhibit high bandwidth (up to 
300MHz - 9Gbps) and provide signal amplification and equalization for high 
performance processing of audio and video allowing the signals to travel great 
distances without quality loss. As a bonus feature, all HDMI outputs can also be 
cascaded.
