HEAVY DUTY Line:
Sound quality and reliability for your PA.

  More reliance and profits on your investment.

All the HEAVY-DUTY line is an international pattern for 19" frames. It is fitted with the ultra-efficient, forced ventilation Dynamic Cooler, protection against short-circuit and overheating, an always silent Auto-Mute,  activation, High/Low-Pass frequency filters and intelligent and adjustable Opto-Compressor/Limiter Crest-Factor. It can be powered on a 110V to 240V AC power line with external selection. An installation technical manual accompanies the equipment. Its servo amplifier unit is on a steel chassis with luminous VU, volume controls, and output level indicator on the front panel. A plug-in drawer is located on the back panel for the various type off input interfaces (modules) at your choice, according to the type of work to be applied. Whenever a new technical breakthrough appears, such as the digital audio, its amplifiers can be updated, by merely exchanging these modules. We can currently choose among the following modules: ADL, SUB-1, SUB-2, and FULL. You can purchase your amplifier with any of these modules for a given application, and in the future replace only the input module with another one having another function. The only ones designed to operate with 4 speakers per channel, providing maximum power and equipped with the revolutionary Linear Bass system.

5 years
warranty! ***

The warranty covering our products has never been meant to be merely concerned with repairing them promptly every time they present a fault, but rather to prevent faults for a long period during their lifetimes. In addition to going through a stringent selection of components and measurements, every Studio R amplifier is in-factory tested, for three 3-hour cycles at full power in a high-temperature oven. It is cooled and tested again at every interval. This Burn-in process is the only internationally proven way of discovering components of a system which could deteriorate prematurely.

Our current fault rate for the Heavy Duty line is only 2 out of every 1,000 devices,
with a 5-year time regular use between two faults.

The following equipment has all characteristics stated above as series items, and are one of the most complete, advanced, and powerful amplifiers on marketplace, boasting a technology and features only to be found in touring-class amplifiers. Also, they are provenly the most durable, robust, and reliable amplifiers available.
