Servo 600 It's better than I hoped for.
I have used Samson products for over 5 years (power amps, powered mixers, powered subs, airline wireless, and mics,). Never a failure, never a problem! I bought a Servo 600 a few months back for monitor use. It served well enough that I have tried it out for front of house use in armories, churches and the like, only to have better sound quality than I have ever had with Peavey amps.
This unit really does a good job with monitors and front of house in small to small/mid-size venues. I have used it with 4 medium foh speakers and with 2 quality foh speakers like yamaha s115v and Peavey sp5. It really performs well with quality speakers. Samson equipment is built really rugged and will hold up well to travel. It has impressed me to the point I am shifting over to all Samson.
