LOUDSPEAKERS LINE OUT

8
The loudspeakers line out is effected by means of a transformer that has
low impedance outputs (4 – 8 – 16 Ohms) and high impedance outputs
(50 – 70 – 100V).
The connection must be made between terminal "0" and the terminal
corresponding to the appropriate impedance or voltage.

Low impedance

One of these three outputs will be used when the loudspeakers do not have a line transformer, and it will be
selected in such a way that the loudspeaker line impedance is the same as the impedance of the amplifi er
output contact.

High impedance

When working with the 50, 70 and 100V lines, it should be remembered that:
The loudspeakers to be connected must have a line transformer.
Eng The total connected power will be the sum of the power absorbed by the loudspeakers and this must be
between 50% below and 20% above the rated power of the amplifi er.
The power absorbed by a loudspeaker with a transformer is indicated on its terminals.This power is on the
100V line. If the transformer is connected to the 70V line, it will absorb half the indicated power, and if it is
connected to the 50V line, it will absorb a quarter of this power. A 30W transformer will absorb 15W if it is
connected to the 70V line and 7.5W if it is connected to the 50V line.
