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
Current Amperes model status, firmware, accessories and project-specific approvals should be verified before formal quotation.
System dependencies
Complete the Amperes system chain
A product is only one part of the deployment. Confirm the supporting components and infrastructure before final model selection or installation.
Dependency links are planning paths, not automatic compatibility claims. Exact model/SKU, interfaces, loading, firmware/software and accessories must be verified for the final project.
Distribution
Zone control
Map amplifier channels to actual zone and load requirements.

Choose from the family, then verify availability
Use the listed models as the selection path. Exact Malaysia SKU, stock/channel status, warranty terms and accessories should be verified at quotation stage.
Maintaining an installed system
Do not assume an older model must be replaced
For installed systems, the appropriate path depends on product identification, supportability, compatibility and condition; the outcome may be repair, continued use, phased replacement or migration.
