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-1Por 650-Pdepending on the needs of the end user.

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.
