The HD series consists of five models with a power output ranging from 230 W/8 Ω per channel, to 5000 W/4 Ω (bridged), all in a 19’’/2U format, ideal for use in fixed installations.HD Series technology combines Class AB for the smaller models HD800 / HD1200, with Class H for the more powerful units HD2000 / HD3200 / HD4000.
All five models are based on our proven High Dynamic Power technology, which means higher dynamic headroom for an outstanding hearing experience and higher efficiency in the ratio of power output versus energy consumed.
They incorporate the soft-start circuit with gradual volume increase, clip limiters and special protection features such as temperature control, overcurrent, DC output and anti-short circuit on the outputs.

Master Audio revolutionized the power amp sector in 1988 by bringing the industry’s first triphonic amplifier, the TP700, to the market.
25 years later, the TP2400, holding true to its original principle, continues to be the benchmark in its class.
The TP2400 is very easy to set up and use, and the results obtained are exceptional. Comparable with more expensive and complex systems, the TP2400 is the ideal option for all types of bars or pubs.
