Kramer Introduces HDMI Distribution Amplifier and Four Isolation Transformers

Kramer Electronics introduced a new 1:2 distribution amplifier for HDMI signals that can store and recall EDID information.

The VM-2HDMI is a compact and high quality 1 input, 2 output distribution amplifier for HDMI signals from tuners, set top boxes, DVD players and other HDMI equipped sources.  The unit supports up to 1.65Gbps bandwidth for compatibility with all HDTV standards including 1080p/60 signals.  It will allow the connection of one HDMI source to 2 HDMI equipped display devices.

The VM-2HDMI features a default EDID setting for fast and efficient connection of the unit.  With a default EDID setting, you can turn on the distribution amplifier and source device without first connecting and powering on any of the displays.  The VM-2HDMI can also store and recall an EDID setting from either connected display device.

Kramer also has four new isolation transformers designed to eliminate noise in video and audio signals caused by ground loop problems. The models are the TR-1, TR-1A, TR-2A and TR-3 and they address the problems caused when the connection between sources and displays can introduce a 50Hz or 60Hz ground loop resulting in unwanted noise in the form of video hum bars or audio hum or buzz.  The new Kramer isolation transformers, the TR-1 for composite video signals, the TR-1A for balanced mono audio signals, the TR-2A for balanced stereo audio signals and the TR-3 for composite video and balanced stereo audio signals, break the ground connections in video and audio transmission lines to eliminate any hum caused by ground loops.

These isolation transformers remove both DC potentials and common mode noise which could be the result of long cable runs.  Each of these models offers various grounding options.  The TR-1 and TR-3 have ground connection for the video signal so that the unit can be attached to an external ground and the TR-1A and TR-2A have dip switches so that the left and right audio in and out signals can be grounded if desired. 

The TR-1, TR-1A, TR-2A and TR-3 are all housed in compact Kramer TOOLS enclosures and are passive in operation making them well-suited for field use.  The TR-2A and TR-3 models are in stock in the US and available for a list price of $130 and $195 respectively.  The TR-1 and TR-1A models are expected to be available in November 2006.
