Precautions for placement and use · Use this unit within its operating temperature range of 5­40º C (40­104º F). In addition, please avoid placement in locations that are very dusty or humid because this could cause malfunction. · Do not give the unit a violent shock. This could cause damage to the internal circuitry or the case. NOTE Please be aware that, as a result of improvements or other changes to the product, photographs, illustrations and other depictions in the Owner's Manual may differ from the actual product. Cleaning the unit Use a soft cloth to wipe the unit clean. Do not clean it with chemical-based wipes, benzene, thinner, alcohol or similar substances. This could damage the surface or cause the color to change. Rack-mounting the unit Use the supplied rack-mounting kit to mount the unit in a standard 19-inch rack, as shown below.

Rear panel (LA-80) 4 INPUTS 1­8 RCA pin jack type input connectors with nominal input levels of -10 dBV (0. 3 V). 5 OUTPUTS 1­8 XLR type output connectors with nominal output levels of +4 dBu (1. 23 V) or -20 dBu (0. 0775 V). [. . . ] This connector is convenient when using multiple LA-80/81MKII units. The specifications are displayed on the top of the unit. NOTE The GND LIFT switches do not cut the ground for the OUTPUTS 4. 7 ALL LIFT switch When other equipment is mounted in the same metal rack, for example, a ground loop can occur through the panel or chassis, and this loop can cause a hum or other noise. If this occurs, engage the ALL LIFT switch to cut the loop. The EUR model does not have this power outlet, so the panel here is blank. q AC IN connector Connect the included power cord.
