PA 50 CA TWO SERIES
PUBLIC ADRESS AMPLIFIER

GENERAL DESCRIPTION:
For the convenience of the users, the AC Mains of the amplifier
series is controlled by the power selector, it provide the two
kinds of voltages: 110V-120V / 220V-240V
For greater operational flexibility, two Microphones can be in-
serted in the amplifier, on which also have "AUX" inputs, which
can provide for the use of radio tuner, CD player and other high
impedance, high power input .
The rear panel selector switch must be tuned in to "PHON" po-
sition when the amplifier is playing recorder.
"MIC", "AUX.CD", "PHON" positions are all set on volume con-
trollers, which can freely adjust the volume needed by users.
You will find it safe and reliable to use the Series; AC
selector is made of insulating material and the rear panel is ins-
talled with connecting-ground terminal. Any other components
are all considered Safety-factor while assembling.

CAUTION
You shall hold the plug firmly to avoid the pull-out of power line
and risk occurring when you pull the power line out from AC
outlet.

Cuando desea operar con altavoces a una distancia superior a
los 50 metros del amplificador, es recomendable la instalación
de transformadores de línea para prevenir las pérdidas de nivel.
Este método se conoce como distribución de tensión constante
y elimina el cálculo de impedancias de carga e instalaciones
serie-paralelo. Con este sistema todos los altavoces se
conectan en paralelo.
Esta salida de tensión constante distribuye la potencia entre los
altavoces. Cada uno de ellos debe disponer de un transformador
de línea de 100 V el cual marca la potencia deseada al
altavoz.
El número total de potencia soportada por los altavoces debe ser
la misma que la potencia de salida del amplificador o menor.

Lo terminales de baja impedancia 4, 8 16 ohms se usan para
un sistema con pocos altavoces o donde la distancia entre el
amplificador y los altavoces sea menor de 50 metros. Es
necesario que la impedancia total sea la marcada por la

Speaker Output
The amplifier may be used in conjunction with a speaker
rated at4, 8, 16 ohms or with 100-Volt constant-voltage
speaker systems.
Low impedance speaker output : 4, 8, 16 ohm
(balanced)
The low impedance 4, 8, 16 ohm terminal is provided for
connection of a few large-output speakers when constant
voltage speaker system is unnecessary or in case the
distance between the amplifier and the speakers is short
enough (less than 50m). It is requested that the total
speaker load impedance be correctly matched to the output
impedance (4, 8, 16 ohm) of the amplifier for most efficient
transfer of power.
Be sure that total impedance of speakers Amplifier must be
in equal, do not raise amplifier output power to above the
permissible input power of speaker if the latter is smaller
than the former. lf the amplifier output power should be
raised above it, by mistake, the speakers would be
damaged. COM 4W 8W 16W 100V

100 Volts speaker output (balanced)
When it is desired to operate the speakers from the
distance, over 50 meters of the amplifier, it is recom-
mended that line matching transformers be installed on the
speaker units to prevent excessive line losses. This method
of load matching known as the constant voltage distribution
system eliminates the calculation of load impedancd and
series-parallel speaker arrangements. ln this method, all
speakers are connected inparallel.
These constant voltage outputs are most convenient for
distribution of power when a number of speakers are
installed . Each speaker must have 100-volt line transformer
with a tap that gives the power desired for that speaker .
The total number of powersettings for all speakers should
be equal to the amplifier power rating or less.
