Powerwise, the QSC PLX 1602 would be adequate for my needs, bridged into two 8 ohm cabs. The 2402 bridged is another option. The 1602 has Class AB output circuitry. The 2402 has Class H (2-step)output circuitry and "Advanced Thermal Management". Is this any reason to spend a couple hundred more dollars and "move up" to the 2402?
