The 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-654 provides 4 HDMI compliant outputs, the 1T-DA-658 provides 8 HDMI compliant outputs and the 1T-DA-664 provides 4 HDMI compliant outputs plus separate audio distribution via integral 1x4 analog stereo and 1x4 S/PDIF coaxial audio. Each product in this series is compatible with HDMI v1.3 specifications; a cutting-age technology that supports Deep Color (10-bit and12-bit) video plus new, lossless Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio digital audio. In addition, all devices exhibit high bandwidth (up to 225MHz - 2.25Gbps) and they provide signal amplification and equalization for high performance processing of audio and video allowing the signals to travel great distances without quality loss. A rear panel switch allows the EDID reference to be selected from either a connected display on a priority basis or from an internal resolution look-up table All DAs can also be cascaded for expanded functionality and all HDMI distribution amplifiers can function as DVI Distribution Amplifiers using cable adapters. An optional Rack Mounting kit provides for mounting either one or two of the 1T-DA-654 or 1T-DA-664 HDMI DAs in a 19” Rack. Optional Rack Ears are available for mounting a single 1T-DA-658 in a standard 19” rack.
