The brand-new QUANTUM QL amplifiers in the ESX portfolio are technically the smaller siblings of the QE models. Ideally, they can be used in installation spaces that are very tight. They are also emission-free and, like the larger QE models, feature the best Class-D technology, fulfilling all requirements for performance, sound quality, and settings. The visual appearance and dimensions of the QL models are the same as those of the XE-DSP amplifiers and the X-DSP processor, allowing for the creation of high-quality DSP systems with a lot of power when these devices are combined. The QUANTUM QL models come with a compact remote control. The 24V versions can operate in trucks and coaches with a 24-volt electrical system.
