The QUANTUM QL amplifiers in the corresponding ESX series are technically the smaller siblings of the QE models. Ideally, they can be used where installation space is very limited. They are also emission-free and feature high-quality Class-D technology, meeting all demands for performance, sound quality, and adjustment options.
The visual appearance and dimensions of the QL models are shared with the XE-DSP amplifiers and the X-DSP processor, allowing for the combined use of these devices for the implementation of high-quality DSP systems with great power. The QUANTUM QL models also come with an affordable remote control.
