TEXONIC EX660D 660W 100V Commercial Mixer Amplifier

High-Power 100V Commercial Mixer Amplifier TEXONIC EX660D 660W 100V Commercial Mixer Amplifier The TEXONIC EX660D is the highest-power model in the EX Series, designed for larger commercial background music, paging and public-address systems that require strong amplifier output from a compact 1U rack-mount chassis. With 660W of Class-D amplification, the EX660D is suitable for larger warehouses, banquet halls, gyms, schools, hospitality spaces, multi-floor facilities and other commercial installations using compatible 100V distributed speakers or 8–16Ω low-impedance speaker systems. 660W Class-D Output 100V or 8–16Ω Output Bluetooth + USB Playback 3 Mic Inputs 1U Rack Mount Overview Features Specs Speaker Load What’s Included Manual Product Overview The EX660D is built for larger commercial audio systems where more amplifier power is needed for multiple speakers, paging zones, background music or public-address coverage. Built-in Bluetooth and USB playback provide simple music source options. Three microphone inputs, two AUX inputs and a line output support paging, announcements and external audio equipment. Chime and alarm functions, priority control, tone adjustment and front-panel status indicators make the EX660D practical for everyday business use. Integrated short-circuit, overload and high-temperature protection help protect the amplifier during demanding installations. Best For Larger warehouses, banquet halls, gyms, schools, hospitality spaces, multi-floor facilities, public-address systems and larger commercial background music systems. System Fit Compatible 100V distributed speaker systems or 8–16Ω low-impedance speaker systems. Use only one speaker-output type at a time. Planning Note: For 100V commercial systems, calculate the total wattage of all speaker taps and leave suitable amplifier headroom instead of running the amplifier continuously at its maximum rated output.

Do not connect both speaker-output types at the same time. Recommended 100V Speaker Load For 100V speaker systems, add together the wattage tap setting of every connected speaker. The EX Series manual recommends keeping the total combined speaker tap wattage at or below 80% of the amplifier’s rated output power for proper headroom and reliable operation. 660W × 80% = 528W recommended maximum speaker load 660W amplifier − 528W recommended load = 132W headroom This gives the system approximately 20% amplifier capacity available instead of operating continuously at the maximum rated output. Speaker Load Example Total 100V Load Typical Use Light system load Up to 165W total Lower-level background music or smaller speaker groups Medium system load Up to 330W total Moderate background music and paging coverage Recommended maximum design load Up to 528W total Best target range to keep about 20% headroom Full rated amplifier output 660W total Not recommended for continuous design load because it leaves no headroom Important: Connect 100V speakers in parallel or daisy-chain to the EX660D 100V and COM speaker terminals with consistent polarity. Do not use the 8Ω speaker setting on transformer speakers connected to a 100V speaker line. Setup note: Turn off the amplifier and disconnect AC power before changing speaker wiring, output mode or speaker wattage taps. After installation, check that no protection, overload or clip indicator stays active during normal operation.
