Step 1
— Turn all of the equipment off and disconnect all power sources.
Step 2
— Mount the amplifier in either a plenum space, on a rack, under a desk, or on a projector.
ATTENTION:
•
Although the amplifier is plenum rated, the power supply provided with it is not. The power supply must not be placed
in the plenum space. Cables to and from the amplifier must be plenum rated.
•
Bien que l’amplificateur soit conforme à la norme relative aux faux plafonds, la source d’alimentation fournie avec
ne l’est pas. La source d’alimentation ne doit pas être placée dans l’espace plenum. Les câbles depuis et vers
l’amplificateur doivent aussi être classés plenum.
•
Use only the two round mounting holes for mounting the MPA 601. The other four (hexagonal) holes anchor stand-offs
for the internal circuit boards. Using them may damage the amplifier and does not provide secure mounting for the
unit.
•
Utilisez seulement les deux trous pour monter le MPA 601. Les autres quatre trous d’ancrage sont destinés aux cartes
de circuit internes. Le fait de les utiliser pourrait endommager l’amplificateur et n’assurera pas un montage sécurisé
pour l’unité.
Step 3
— Attach the speakers to the MPA 601 using the 2-pole, 5 mm screw-lock captive screw speaker
receptacle on the rear panel.
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.
Step 4
— Attach sources to the MPA 601 unit from the audio source or projector.
The three rear panel audio inputs can be used individually or together:
•
One pair of RCA receptacles (unbalanced)
•
One 3.5 mm stereo tip-ring-sleeve receptacle (unbalanced)
•
One 3.5 mm, 5-pole captive screw receptacle (balanced or unbalanced)

NOTES:
•
The MPA 601 amplifier sums the left and right signals from both the TRS and RCA
inputs to form Sum 1. 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. Refer to the
MPA 601 Series User
Guide
for more details regarding audio summing.
•
The captive screw, RCA and TRS inputs are buffered.
Ensure the audio output of the projector is set to variable. Multiple input options can be used simultaneously and be summed.
