This way, equipment feeding the amp won’t “pop” or “thud” when it’s powered up or down. Power cord we all know what a power cord is. The m•1400/m•1400i has a big beefy cord built in. Pl...

    20 the amp mode switch determines the in- put signal routing within the m•1400/m•1400i amplifier. Shipped from the factory, the switch is set to stereo. This is correct for about 90% of the applications using an amp like this (hence the typical indicator near it). But you may be in the 10% bracket, ...

    21 simply stops. This causes a sine wave to “square off,” and the average power going into the speaker is roughly double that of a sine wave. Square waves sound awful, and could possibly damage your speakers and/or your reputation. The limiter is especially handy when you’re working with loud output...

    23 general precautions and considerations ac power considerations be sure the m•1400/m•1400i is plugged into an outlet that is able to supply the correct volt- age specified for your model.

    24 the extension cord used to supply power to the “amp rack” should have a third wire safety ground to avoid presenting a safety hazard. We also recommend using a cord that has conduc- tors large enough to avoid severely limiting the amplifier’s ability to supply high currents on transients. Power a...
