Power Supply Fan
The power supply is cooled by a single small internal
fan that turns on low when the unit is first powered up.
The fan doubles its speed as the system is driven with
audio. Since the fan draws air in from, and exhausts it
out the side of the cabinet, there must be at least six
inches on the amplifier’s side of the cabinet and ad-
equate air flow.
UM-P Applications
In half-space loading condition, the UM-P will typically
produce a maximum SPL of 135 dB at 1 meter with a
frequency response down to 60Hz, which is perfect for
vocals and most instruments. When using the UM-P in
most applications that require SPL in the sub harmonic
frequencies, such as monitoring drums and bass, the
UM-P should be supplemented with a subwoofer such
as the Meyer USW-1P or 650-P depending on the needs
of the end user. For ideas on integrating the UM-P with
other Meyer Sound products contact Meyer Sound Technical
Support.
The Constant Q design of the horn allows frequencies
outside of the coverage area of the speaker to attenuate
quickly. This is excellent for monitoring where several
different monitors are used in close proximity. When
placing the monitor carefully consider the coverage
pattern of the UM-P and UM-100P.
The UM-1P’s coverage area is:
–6 dB points:
45° H x 45° V
–10 dB points:
65° H x 65° V
The UM-100P’s coverage area is:
–6 dB points:
100° H x 40° V
–10 dB points:
120° H x 60° V
The following drawings illustrate the coverage area of
each horn from three different perspectives in order to
depict the three dimensional coverage pattern.
