the cabinet face, and about 1 meter in front of the
MSL-5.
• If polarity of the high frequency drivers is reversed, a
trough will appear in the response curve centered
near 800 Hz. If in doubt, reverse the polarity of the
Hi amplifier output while you watch the analyzer
display.
2. Multiple cabinet arrays. Each cabinet should first be
tested as above.
• Connect one loudspeaker and advance the pink
noise to a convienent measuring level. Position the
measuring microphone on the axis between the
loudspeaker and the cabinet adjacent to it, and
about 2 meters distant. Note the frequency re-
sponse and overall level.
• Leaving the first loudspeaker connected, connect
the adjacent one and observe the analyzer display.
The entire curve should jump up in level, indicating
correct addition between the loudspeakers. A polar-
ity reversal between the loudspeakers will show up
as severe broadband cancellation.
• Similarly, add in the rest of the cabinets of the array
one at a time, looking for correct addition as each
loudspeaker is connected. (It will be necessary to
reposition the microphone.)
Rigging The MSL-5 loudspeaker has twelve offset pivoting lift
rings (6 top and 6 bottom) fastened externally through
cabinet cut-outs to an internal steel frame. Please
consult Meyer Sound about any questions concerning
MSL-5 rigging strength and loading conditions. If the
structural integrity of any cabinet has been compromised
by damage or negligence, then the safety of the rigging
cannot be assured. All rigging should be done by
competent professionals.
Placement and
Arraying The MSL-5 is designed to function as a 30-degree
arrayable section with additional cabinets being em-
ployed as modular 30-degree building blocks.
