Construction
Electronic structure of amplifier was designed with help of newest technologies. All electronic elements were installed with the SMD technology. The plate is in the massive body made from aluminium, which ensures mechanical resistance and good screening.
Amplifier is secured against overvoltage. External connections are made with F75 W connectors.
On a side wall of casing is a WS outlet to connet with external power supply.
