Connecting a combination of Wall and Ceiling
Speakerswith100VLMT
130 Ceiling Speakers with 100V LMT at 4 Watts and
80 Wall Speakers with 100V LMT at 6 Watts can be
connected together. The power drawn from the amplifier
shouldnotexceed1000Watts.
Useof 70VoltLine
A loudspeaker / Driver Unit with its LMT adjusted to the
15W tap, when connected to COM and 100V terminals
on the Amplifier's Terminal Strip will draw 15W from the
Amplifier but when the same is connected to COM and
70V it will only draw half power i.e. 7.5W. A good use of
70V line tap can be made in installations where large
number of Speakers / Driver Units are to be installed for
moreevendistributionofsound.
Correct Phasing of Loudspeakers
lWhen two or more Speakers / Units are installed in the
same area and are facing the same direction, it is
essential that their cones / diaphragms act in unison.
Otherwise the sound level of one speaker will be
cancelling the sound level of the other. To avoid any
mistake, the terminals of Box speakers and the Driver
Unitsaremarked '+' &'-'.AlwaysconnecttheCOMofthe
Amplifierto'-'ofspeaker&2 /4 of the amplifier to the
'+'ofthespeakers.
lIn case of LMT’s the COM of all the LMT’s should be
connected to the COM of the red strip terminal of the
amplifier and the power tap to 100V line as shown in
figure.
IMPORTANT
l
l
When 70 / 100 Volt line is being used, no speakers / driver units should be connected to 2 / 4 (Low
Impedance)Tap.
Loudspeaker / driver unit should be connected to either COM-100V or COM-70V terminals, but never to
