*The maximum recommended amplifier power rating will ensure proper system headroom to allow for
occasional peaks. We do not recommend sustained operation at these maximum power levels.
Occasional refinements may be made to existing products without notice but will always meet or exceed
original specifications unless otherwise stated.
