Speaker Output Connector
— This 2-pole 5 mm screw-lock captive screw connector
is used to connect speakers to the amplifier. The MPA 601-70V provides up to 60W
for a 70V distributed sound system, while the MPA 601-100V provides up to 60W for a
100V distributed sound system.

ATTENTION:
•
Do not ground or short the speaker outputs as this will damage the amplifier.
•
Ne pas mettre à la terre ni créer de court-circuit dans les sorties de l’enceinte,
afin d’éviter tout risque de détérioration de l’amplificateur.
The MPA 601 amplifiers sum the left and right signals from both the TRS and RCA
inputs to form Sum 1 (see figure 10 below). Sum 1 is then weighted. At the same time,
the amplifier sums the left and right signals from the captive screw input to form Sum 2.
Sum 1 and Sum 2 are then summed together to form a single mono signal.
NOTE:
All inputs are buffered.
