AUDIO AMPLIFIER 8 CHANNELS LA I OTTO from installation – 530 W per channel

Original price was: €4,118.66.Current price is: €2,883.06. IVA esclusa

The Lombardi LA I OTTO is an 8-channel all-analog class AB audio amplifier for installation designed by us in Italy to operate at high efficiency while maintaining accurate sonic performance across the entire bandwidth even under stress conditions.
In addition to the 8 audio amplifiers, the Lombardi LA I OTTO has 8 crossovers and 8 independent optical safeguard limiters for each channel. In order to maintain the high standard of Lombardi made in Italy quality, the product is handcrafted with high quality components and switching transformer.

The Lombardi LA I OTTO before being placed on the market is tested up to the threshold (with impedances lower than 4 Ω).
