{"product_id":"toa-da-250f-cu","title":"TOA DA-250F CU 4-Channel Class D Rack Power Amplifier","description":"\u003cp\u003eThe TOA DA-250F CU is a four-channel Class D power amplifier built for permanent installation and commercial audio applications where rack space, weight, and power efficiency are critical constraints. Delivering 250 W per channel into 4 ohms or 500 W bridged per channel pair into 8 ohms, it covers a wide range of loudspeaker configurations without requiring additional rack units. Each channel runs from its own independent power supply, which means a fault or overload on one channel does not degrade performance on others, a meaningful advantage in multi-zone paging, background music, and distributed audio installations.\u003c\/p\u003e\u003cp\u003eIntegrators working in education facilities, houses of worship, corporate AV, and hospitality environments will find the DA-250F CU directly suited to their needs. The switching power supply keeps weight at 6.6 kg and power consumption low relative to output, simplifying both shipping and physical installation. Tamper-proof control covers and a CH1 broadcast mode switch allow system designers to lock in a configuration and protect it from accidental adjustment by non-technical staff. Forced air cooling via low-noise constant-speed fans maintains thermal stability across continuous operation, while onboard protection circuits guard against overcurrent, short circuit, DC offset, and thermal events at both the heatsink and interior chassis level.\u003c\/p\u003e\u003cp\u003eCompared to conventional linear amplifiers in the same output class, the DA-250F CU occupies a single rack unit and draws significantly less idle power, making it practical in dense rack builds where heat management is a concern. Per-channel LED metering for input, output, peak, and protect status gives technicians immediate visual diagnostics without connecting external test equipment.\u003c\/p\u003e","brand":"TOA ELECTRONICS, INC","offers":[{"title":"Default Title","offer_id":52446335959224,"sku":"52095","price":1970.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/52095_TOA-DA-250F-CU-4-Channel-Class-D-Rack-Power-Amplifier_ALT01sqr.jpg?v=1789136157","url":"https:\/\/soundpro.com\/products\/toa-da-250f-cu","provider":"SoundPro","version":"1.0","type":"link"}
