The HDDA12V13 1x2 distribution amp from Octava distributes HDMI 1.3 and includes a Toslink connection to take the PCM, Dolby Digital, or DTS audio directly to a home theater audio system. The unit handles bandwidth up to 6.75Gbps for displays up to 1080i/p. All connections are on the rear panel, while the front has the power button and port activity LED. The processing features Octava’s ClearEye design to reduce timing errors and relevels the signal using a data slicer circuit and an HDMI limiting amplifier.
The PureLink HD-2100 HDMI 2x10 distribution amplifier sends two HDMI inputs to 10 outputs at up to 1.65Gbps and video resolution up to 1080p. The signal is HDCP-compliant on all 10 outputs. The 1RU amp includes a 12VDC power supply, and its maximum power consumption is 60W.
Providing HDMI 1.3 from one or two inputs to as many as 10 outputs, the HD-D210N HDMI distribution amplifier from RTcom USA supports HDCP and bandwidth from 25MHz to 225MHz on all outputs. The unit supports video resolutions up to 1080p at 60Hz with 36-bit color depth along with Dolby TrueHD and DTS-HD sound. With the unit’s internal EEPROM, EDID can be saved from the display or the user can select factory preprogrammed EDID. The internal circuitry provides a direct connection from each input to each output rather than using a daisy-chain wiring scheme. A 12VDC 3-amp power supply is provided, and the unit’s power consumption is 15W.
With signal presence indicators for the input and all four outputs, the Sima Products VS-HD14 also has digital audio outputs to feed a home theater amplifier. An infrared in/out port is available for flexible system configuration, and the half-rack-sized, all-metal chassis can be fitted with an optional rack mounting kit. Providing a boost for HDMI video, the unit can be cascaded for longer cable runs.
Resolution up to 1080p and WUXGA is supported by the HDS-4P from SmartAVI along with HDMI 1.3c-deep-color- and HDCP-compliant devices. The formats include DTS-HD Master Audio, Dolby TrueHD, Dolby Digital, DTS, DVD-Audio, LPCM, SACD, and MPCM. The HDMI four-port splitter runs on an external 5DVC 2-amp power supply module, and it supports home theater applications through CEC with a cable range of up to 20ft. to displays.
The StarTech ST128HDMI eight-port HDMI distribution amplifier has a built-in EDID simulator and HDCP keyset allowing each output to operate independently. The rackmountable unit can be cascaded up to three layers for increased reach to displays or more outputs, supporting resolutions from VGA to UXGA and 480p to 1080p at 1.65Gbps bandwidth. All connections are on the rear panel, and the front panel includes a power LED, sync and enhance LEDs, and a connection indicator LED for each output channel. The unit includes a 5VDC 2.6-amp power adapter.
For running an HDMI 1.3 input signal to as many as eight outputs with 10-bit and 12-bit deep color along with Dolby TrueHD, Dolby Digital Plus, and DTS-HD digital audio, the 1T-DA-658 distribution amplifier from TVOne provides equalization for signal loss on HDMI cables. The unit also features automatic EDID discovery, and the outputs may be cascaded for greater flexibility. An internal jumper is used to select between EDID discovery from the display or from an internally stored table. Along with the power LED, the front panel of the rackmountable unit has an LED that indicates whether an HDMI or DVI signal is on the input. Another indicator shows the presence of HDCP, and a third LED confirms synchronization of the HDCP signal.
The Xantech HDMI1X4 supports 1080p resolution to four outputs and the unit includes an internal DIP switch panel for settings to control switching delay, EDID parameters, and infrared control codes. Bandwidth support extends to 1.65Gbps, 12-bit color, and the unit’s features include lip sync and CEC passthrough along with support for Dolby Dolby TrueHD and DTS Master Audio.
