QSC has been the world leader in Amplifiers for over 30 years. Just about every club and stadium in the world has QSC at its head end powering its speakers. At HDH we figured, why should our clients homes be different? We install amplifiers that are expected to run 24 hours a day, 365 days a year for the life of the system. QSC has one of the best warranties in the business and being one of the top dealers in the US, HDH gets top service from them (not that we ever need it)!
