What is the maximum output level of a single channel amplifier?

Why doesnt a headend ever reach this output level?

Respuesta: 

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 in which case 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:

  1. The internal loop-through loss of the amplifier.
  2. The loss of the link used to interconnect them.

The contribution of these two losses is about 1 db.

Because of this, the maximum output level of the headend is always lower than that specified in the technical specs of the single channel amplifers.
