narrow pickup pattern. You should therefore place the monitor in the rear,
but at a slight angle.
High frequencies are unidirectional while low frequencies are omni
directional. Being that this is a full range enclosure, it is important that the
speaker be placed so that the high frequencies reach the intended listeners
properly. Make certain that no person or object could come to interrupt the
line-of-site between the loudspeaker and the performers.
When using more than one loudspeaker, you have to account for
phase alignment. When the speakers are close together this is not usually an
issue. However, when they are far apart, the sound from one speaker may
reach the ear a fraction of a second before the other. This will cause certain
frequencies to cancel out, resulting in a hollow sound. To avoid this, you
may have to use a delay processor to align the sound from the speakers.
Maintenance and Safety
Do not expose the speaker to moisture.
Avoid hot and cold temperature extremes.
Clean using a damp cloth. Make sure that no moisture contacts the
drivers. You can use a hand vacuum to clean the carpet.
Do not attempt to service the unit. Refer service to a certified Pyle Pro
technician.
This loudspeaker is capable of producing extremely high SPL levels.
Use earplugs when necessary.
