The input circuits of the Alesis amplifiers are electronically balanced. They may be fed from either symmetrical (ÒbalancedÓ) or unbalanced sources. There are two combination XLR/1/4Ó (6.3 mm) jacks provided, one for each channel, and a barrier screw terminal strip for connecting bare wire or crimp terminals. See Figure 2.
