Using Multiple Distributed Line Voltages
The MPC amplifiers allow you to connect distributed lines to any of the 100V, 70V, and 25V
outputs at the same time. For example, a single channel could drive both a 70V and a 25V
line; such flexibility could save you the expense of an additional amplifier.
The total power of all the speakers connected to the AUDIO TRANSFORMER outputs should
always be less than the power rating of the channel. For example, an MPC300T is rated for a
maximum power output of 250 watts; therefore, the total of all the speakers’ power taps for
all the lines connected to the 100V, 70V, and 25V outputs must not exceed 250 watts.
MAKE SURE THAT LOCAL BUILDING CODES PERMIT THE USE OF THE
OUTPUT VOLTAGE YOU SELECT.
BRIDGED MONO MODE
CAUTION:
ALL MODELS —Output
voltages as high as 160
volts rms are available
between the MPC
amplifier’s bridged termi-
nals (200 volts at isolated
outputs).
MPC200T, MPC300T, and
MPC600T
(140V and 200V
operation)—Fully insulated
CLASS ONE wiring must be
used to connect the ampli-
fier to the loudspeakers.
MODE BRIDGÉ MONO:
ATTENTION
TOUT LES MODÈLES —Des
tensions de sorties aussi
élevée que 160 volts rms
sont disponible aux bornes
du amplificateur MPC en
mode bridgé mono (200
volts aux sorties isolés).
MPC200T, MPC300T, et
MPC600T
(opération 140V
et 200V)—On doit utiliser
du câblage entièrement
isolé de CLASSE 1 pour
relier l’amplificateur aux
haut-parleurs.
VORSICHT BEI MONO-
BRÜCKENBETRIEB:
ALLE TYPEN —Zwischen
den Ausgangsklemmen der
MPC-Verstärker können
Ausgangsspannungen bis
160 Volt RMS anliegen
(200 Volt bei isolierten
Ausgänge).
MPC200T, MPC300T, und
MPC600T
(140V- und 200V-
Betrieb)—Der Anschluß
muß vom Verstärker bis
zum Lautsprecher mit
vollisoliertem Kabel
erfolgen.
PRECAUCIÓN PARA EL
MODO MONO PUENTE
TODO LOS MODELOS —
Voltajes de salida de hasta
160 Vrms existen entre los
terminales de puente del
amplificador MPC (200
voltios a las salidas
aisladas).
MPC200T, MPC300T, y
MPC600T
(operación 140V
y 200V)—Utilice cableado
de CLASE UNO totalmente
aislado para conectar las
altoparlantes.
Bridged Mono Mode
Bridged Mono mode combines the output power of both channels to drive a single load.
Channel 2 is fed with an inverted signal from Channel 1. Thus, when one channel “pushes,”
the other “pulls,” providing twice the voltage swing of a single channel. The speaker connects
between the “+” terminals of each channel.
