Detailed Description SmartAmp 30
SmartAmp 30 supplies four independent 250 W amplifier channels with onboard DSP. Each channel can deliver its rated output without sharing power with another channel. It supports 4–16 Ω loudspeakers and 70/100 V distributed lines in commercial installations.
Rear-panel switches select the EQ and limiter preset for the connected Optimal Audio loudspeaker. Installations needing other profiles can use the SmartAmp Custom Configurator. Balanced Euroblock line inputs and Euroblock loudspeaker outputs provide the audio connections.
The full-width 1U chassis fits a standard 19-inch rack and operates from a universal 100–240 V mains supply. ZonePad VL1 can provide local volume adjustment through GPIO. Adding a Zone controller brings source routing, timed routines and browser-based WebApp control to the complete system.
