High Dynamic Professional Power Amplifiers
new design with adjustable power limiters
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.
We know you want total control and adjust even the finest detail of your installation.
For this reason the new design incorporates a detachable front panel which gives you access to a limiter threshold adjust for each channel.
Full control in a pro way!
BETTER TEMPERATURE CONTROL
On first-line amplifiers with the most demanding performance is really a big challenge keep temperature under control.
We’ve got a solution thanks to a new power module with proprietary high efficiency heatsink design, that keeps the power stages at a low working temperature. In addition to this, the temperature of the power modules is continuously sensed and in case of abnormally high temperature, the output power will be automatically regulated to avoid a thermal stop.
NEW INTERNAL DESIGN: MORE COST-EFFICIENT
In HD amplifiers we have developed a new internal design with new and optimised components which allow us to decrease production cost.
This means maximising performance and saving cost for the final user.
