Vand amplificator profesional pt sonorizari, cluburi etc. Lab Gruppen C28:4 cu 4 canale, putere totala 2800W.

Amplificatorul e in stare de functionare si a fost folosit pana recent intr-un club pe partea de top-uri.
Sunet excelent, foarte puternic.

Daca sunteti interesat, contactati-ma pe mesagerie pentru un link cu un clip cu un mic test al amplificatorului.

Prefer predare personala.

Pret 6500 Ron Negociabil.
