The Mackie SRM150 Compact Active PA System is ideally suited for applications ranging from A/V to live music performance and can be mic stand mounted, placed on a tabletop, or used in traditional stage monitor position. The built-in three-channel mixer accepts mic/line inputs via combo connector (with switchable phantom power), and offers CD/MP3 inputs with a dedicated level control for added versatility. Tone-shaping/feedback control duties are handled by Mackie 3-band active EQ, and a built-in limiter protects the powerful 150 watt Class-D amplifier and its exceptionally loud 5.25” full-range speaker. The cabinet is robustly made of the same composite material as the legendary Mackie SRM450. The SRM150’s lightweight, durable finish makes it ideal for portable sound system use.
