M•1400/M•1400i AMPLIFIER M•1400/M•1400i High-Current Power Amplifier (continued from page 1)  The M•1400/1400i uses a unique T-Design constant-gradient cooling tunnel that draws air in through the front of the amplifier and forces it out through the amplifier's sides. The T-Tunnel design provides a shorter, more direct path for cool air. This allows for reduced heat build up and cooler transistor operation.  The amplifier has a subwoofer mode that allows you to turn on the built-in subwoofer crossover. When activated, the signals appearing at the left and right inputs are summed, directed to a low-pass filter, and routed to both output stages. The inputs are summed regardless of stereo, mono, or bridge amp mode selection. A switch selects the cutoff frequency of the filter at either 63Hz or 125Hz. www.mackie.com 16220 Wood-Red Road NE, Woodinville, WA 98072 USA 800.898.3211, fax 425.487.4337, [email protected] UK +44.1268.570.808, fax +44.1268.570.809, [email protected] Electronic files for this product available at: www.mackie.com This Specification Sheet Owner/Operator's Manual M1400_SS.PDF M1400_OM.PDF LOUD Technologies continually engages in research related to product improvement. New material, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current LOUD Technologies product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated. ©1999-2004 LOUD Technologies Inc.
