Why this function matters
System role before model number.
Amplifier power is selected from the verified speaker load, design headroom, duty cycle, zoning and redundancy strategy—not from room size alone.
QP2000 Series
125W, 250W, 375W and 500W variants for conventional PA.
QD2000 Series
Current high-efficiency Class-D amplifier family for projects where rack space and power efficiency are priorities.
Representative system deployment: In one 100V PA rack, four QP2500 amplifiers were arranged as three duty amplifiers plus one standby amplifier to provide operational redundancy. This is one amplifier configuration example; quantity, power rating and standby strategy are engineered from the actual speaker load and zoning plan.
Selection checks.
Verify before reuse
Check the actual rack, speaker loads, line condition, cabling, power and control interfaces before assuming compatibility.
Document priorities
Define normal audio, paging, emergency override, fire-alarm triggers and fallback behavior before finalising the equipment list.
Confirm current model status
PNSS reconfirms current Amperes model status, firmware, accessories and project-specific approvals before formal quotation.
