Amperes QP2500 power amplifier
Choose 100V PA amplification for the connected speaker load, zone plan and standby requirements. Compare Amperes QP2500, QP2000 Series and QD2000 Series options below.
How it works
Match amplifier power to the speaker circuits.
Add the connected speaker loads for each amplifier, then allow design headroom and account for duty cycle, zoning and standby operation.
QP2000 Series
125W, 250W, 375W and 500W amplifier variants for conventional PA systems.
QD2000 Series
High-efficiency Class-D amplifier family for projects where rack space and power efficiency are priorities.
Choosing amplification: Size each amplifier from its connected 100V speaker load and required headroom. Set the standby arrangement to suit the system’s operating requirements.
