what is the meaning of the maximum output level of a single channel amplifier?
the standard din45004 specifies the measurement procedures to evaluate the maximum output level of a single amplifier.
nevertheless, a single channel amplifier is always part of a headend and then it is combined with other amplifiers.
when this channel amplifier is looped-through with the rest of the amplifiers, the final output level of the headend is affected by:
the contribution of these two losses is about 1 db.
because of this, the max. output level of the headend is always lower than that specified in the technical specs of the single channel amplifers.
