Prijs op aanvraag


This series of audio power amplifiers was designed to fulfil an evolving market in the most flexible and professional manner. 
The new range responds to precise operating criteria, and was designed and tested to guarantee total reliability of use, also with continuous operation. 
Thanks to the use of power supply switching with SMPS (switch mode power supply) technology and obtaining 70/100V electronically without transformers, it was possible to insert as many as 4 entirely independent audio power amplifiers in a single cabinet, succeeding in containing the weight and size.

•    4 constant electrical impedance outputs (4 ohm)
•    4 constant voltage outputs (70/100V) obtained electronically without the use of output transformers.
•    Balanced inputs for each channel
•    Priority balanced input with independent level control of each channel.
•    Independent Master control for each channel.
•    Independent Low and High pitch control on the 4 channels.
•    PA-HF filter individually inserted at the rear of each channel
•    LED Protection Indicator
•    LED signal indicator
•    Operation mode LED indicator (4 ohm/70/100V)
•    SMPS (switch mode power supply) switching technology
•    2 U-shaped fins to fasten to a 19" rack
