The TOA DA-150EH-AM 3CU is an eight-channel Class D power amplifier rated at 150W per channel across 70V and 100V distributed audio lines, designed for systems integrators and AV engineers deploying large-scale commercial sound installations. Per-channel DIP switching between 70V and 100V operation gives designers the flexibility to adapt to different speaker line requirements within a single chassis, eliminating the need for separate amplifiers across zones.

At 1U in an EIA-standard rack, this amplifier is a practical choice for installations where rack space is at a premium, including hospitality venues, retail environments, corporate campuses, houses of worship, and transportation hubs requiring reliable background and foreground music distribution alongside voice announcement capability. The eight electronically balanced inputs accept removable terminal block connections, simplifying field wiring and future serviceability without proprietary connector dependencies.

Comprehensive onboard protection circuits address short circuit, open circuit, thermal overload, excessive input, ultrasonic, and RF conditions, reducing service call risk in unattended equipment rooms. Per-channel signal, peak, and protect indicators give technicians clear at-a-glance system status during commissioning and maintenance. Forced air cooling sustains continuous operation across demanding multi-zone deployments where the amplifier runs extended hours at high load.
