SSOUNDS A4-600
4-channel 1U Class-D installation amplifier, 4 × 600 W into 8 Ω, XLR and Euroblock inputs, speakON outputs.
Not every installation needs a touring amplifier. The A4-600 is a 4-channel 1U Class-D rack amplifier at 600 W per channel into 8 Ω for the background music, paging and fill zones of a building: analog XLR and Euroblock inputs with link outputs for daisy-chaining a source along the rack, speakON outputs, input sensitivity selectable per channel between 0.775 V and 1.4 V, and stereo, bridge and parallel modes. The front panel carries a gain control per channel and protect, clip and signal indicators. We specify it for retail, restaurants, hotels, schools, offices and public address zones.
