500W Power for Large Commercial Music & Paging Systems
The TEXONIC EX500D is a 500W Class-D commercial mixer amplifier designed for larger 100V speaker systems that need background music, microphone paging and everyday announcements from one compact unit.
Bluetooth and USB playback, three microphone inputs, two AUX inputs, paging priority and a slim 1U rack-mount chassis make it a practical audio centre for large retail stores, schools, gyms, banquet facilities, warehouses and other commercial spaces.
When Is the EX500D a Good Fit?
Plan Your 100V Speaker Load
For a 100V system, add together the selected wattage tap of every connected speaker. AVTECK recommends leaving approximately 20% amplifier capacity unused rather than designing the system continuously at the full 500W rating.
| Speaker Tap | Example Quantity | Total Load |
|---|---|---|
| 10W | 40 speakers | 400W |
| 20W | 20 speakers | 400W |
| 30W | 13 speakers | 390W |
| 50W | 8 speakers | 400W |
Examples assume all speakers use the same tap. A real system may mix different speaker tap settings as long as the combined load remains within the planned amplifier capacity.

Commercial Speaker Compatibility
The EX500D supports a 100V constant-voltage speaker line for larger distributed commercial audio systems and an 8–16Ω low-impedance output for compatible speaker configurations.
For larger business installations using many speakers or longer cable routes, the 100V output is normally the more practical configuration.
