|The Monitor Audio De-Tox CD combines ultra-high speed frequency sweeps and high-energy random noise to allow speaker drivers to reach their optimal operating condition quickly and without damage. Each of the De-Tox disk's four burn-in tracks has been designed for a specific application. Track 1, of twenty minutes duration, is created to optimise stand mount speakers. Tracks 2 and 3, lasting twenty minutes each, are calibrated for 2 and 3-way floor standing speakers respectively. Track 4 (five minutes) performs a quick system refresh before each listening session.
