ESX Quantum QL500.1 Monoblock Class D Digital Car Amplifier 500W

ESX Quantum QL500.1

The brand new QUANTUM QL amplifiers in the ESX portfolio are technically the little siblings of the QE models.  They are ideal for use where the installation space is very tight. They are also emission-free and, like the large QE models, have the finest Class D technology on board, which leaves nothing to be desired in terms of performance, sound quality and setting options.

The QL models share the optics and dimensions with the XE-DSP amps and the X-DSP processor, so that high-quality DSP systems with a lot of power can be built up by combining the devices. The space-saving remote control is also included with the QL models.
