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.MAIN FUNCTIONS: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 channelPriority 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 channelLED Protection IndicatorLED signal indicatorOperation mode LED indicator (4 ohm\/70\/100V)SMPS (switch mode power supply) switching technology2 U-shaped fins to fasten to a 19\" rack"}
