1.0 INTRODUCTION Thank you for purchasing this HDMI switcher from Audio Authority. The Model 1372A and 1374A switchers are designed to allow selection of 2 or 4 inputs respectively for display on an HDMI compliant television or signal distribution system. These version 1.3 HDMI switchers support all standard HDTV formats, PC formats from 1024x768 through 1920x1200, and embedded HD-Audio. The switchers can be controlled via the front panel, the included infrared remote control and/or RS-232 control.
2.0 GETTING THE BEST RESULTS Many factors influence the quality and reliability of HDMI switcher installations. Consider the following and take basic precautions suggested below to ensure the best possible performance. • Output display device. The quality of the output signal depends largely upon the type and quality of the HDMI display device used; some televisions simply look better than others. • Distance between the sources and the display.
4.0 CONNECTING THE HARDWARE Please study the front and rear panel drawings and become familiar with the signal input, outputs and power input. MRN-CLUX41AP-1AA Model 1374A 4X1 Switcher 1 2 3 4 INPUT ENHANCE POWER MRN-1TSX634-2 HDMI OUT 5V DC HDMI IN 4 3 2 1 RS-232 • Connect HDMI approved cables from the HDMI sources to the inputs of the switcher. Cable length can be up to 30 meters – preferably shorter. • Connect the output of the switcher2008.03.
4.1 Using the Locking Cable Securing Feature If HDMI cables are used that are equipped with locking type connectors, remove the Philips head screws from the rear of the unit just above the HDMI connectors and replace them with the hex jackscrews included with the accessory pack. After screwing these into the threaded holes vacated by the Philips head screws, the jackscrew provides a threaded receptacle for the screw that is part of the locking HDMI connector on the cable.
5.3 Switcher Operation via RS-232 Machine Control The 1372 and 1374 HDMI Switchers may be operated using RS-232 protocols. The technical information needed is provided in the two charts below. A system using RS-232 control should be wired and programmed by a qualified custom integrator.

6.0 TROUBLESHOOTING • For higher resolutions such as 1080p, first make certain that the input cable is as short as possible and none of the output cables are more than 15 meters long. HDMI cable design and quality are extremely important in long cable runs where capacitance can severely effect performance. Our 1391A Extender/DDC Corrector may be a necessary accessory to use in extreme length applications. • Make certain that the switcher is receiving power by looking at the power LED.
