ORAmplifier Selection Considerations
- How much power is needed (less powerful amplifiers can be used if you don’t need all the SPL the speaker is capable of producing. However, pushing a lowerpower amplifier into clipping can damage the speaker).
- How much DSP and which DSP functions are required.
- Whether the amp needs to be networked (DCi-N).
- Project’s budget.
