Pure Resonance Audio DA2240 2-Channel 240W 70V Power Amplifier

Pure Resonance Audio DA2240 is a 2-channel 240W power amplifier built for flexible 70V and low-impedance commercial audio systems in one clean rack-ready design.

The Pure Resonance Audio DA2240 is designed for commercial installs that need dependable power, cleaner rack layouts, and more flexibility than a basic single-mode amplifier can offer. Sold individually, this 1U Class D power amplifier delivers 240W per channel and lets each channel run either a 70V distributed speaker line or a 4 to 16 ohm speaker load. That makes it a strong fit for offices, schools, restaurants, retail, houses of worship, warehouses, and other multi-zone spaces that need paging, background music, or mixed speaker system designs.

1. What makes the Pure Resonance Audio DA2240 different from a basic 70V amplifier?
Its biggest advantage is that each channel can be switched independently for either 70V or 4 to 16 ohm operation, which makes it much more flexible for mixed speaker system designs.

2. Is the DA2240 a good fit for commercial paging and background music?
Yes. It is a strong option for offices, retail spaces, schools, restaurants, and similar environments that need reliable power for distributed audio, paging, and music playback.

3. Can this amplifier help reduce rack space and equipment count?
Yes. Because it can power different types of speaker zones from one 1U chassis, it can simplify the rack and reduce the need for multiple separate amplifiers in some installations.
