ESX QL800.4 - 4-channel digital amplifier

QL800.4

  QUANTUM QL  amplifiers are technically the little brothers of the  QUANTUM QE  models. They are ideal for use in situations where installation space is very limited. They are also emission-free and, like the larger QE models, feature the finest Class D technology, which leaves nothing to be desired in terms of performance, sound quality, and adjustment options. The space-saving remote control is also included with the QL models.
