Detailed Description SmartAmp 10
SmartAmp 10 combines two-channel amplification with DSP for Optimal Audio loudspeakers. Rear-panel switches select a loudspeaker preset, applying its EQ and limiting settings. The Custom Configurator supports additional loudspeaker profiles and configurations for installations that need them.
The amplifier is nominally rated at 2 × 125 W, with a maximum of 250 W shared between the two channels. This allows an uneven allocation when the channels drive different loads. Both conventional 4–16 Ω loudspeakers and 70/100 V distributed lines are supported.
Its half-width 1U enclosure can share a rack space with another compatible SmartAmp using the appropriate kit. Balanced Euroblock inputs and Euroblock speaker outputs provide the audio connections. ZonePad VL1 adds local volume control through GPIO, and a Zone controller adds routing, scheduling and WebApp access. The mains supply accepts 100–240 V.
