MA Series Power Amplifiers
8 Specifications
Maximum Power Notes:
All maximum power specifications are based on 0.1% regulated AC mains and an ambient room temperature of 70°F (21°C). International units with multi-tap transformers are specified for the best-case transformer tap (normally 240 VAC, 60 Hz). Although it is an unusual condition, your amplifier can function well with AC mains volt- ages up to 10% over the specified line voltage. With overvoltage conditions, your amplifier may be capable of delivering instantaneous power levels up to 20% greater than the specifications in the matrix.
1. A single cycle sine wave is presented to the amplifier and monitored for nonlinear distortion. The average power during the burst is reported. Loudspeakers must be able to withstand this level if they are to be safely used with this ampli- fier.
2. A 40-millisecond sine wave burst (10% duty cycle) is presented to the amplifier and moni- tored for nonlinear distortion. The average power during the burst is reported. This power level is a measurement of the amplifier’s maximum tran- sient power than can be perceived by the human ear.
