Loudspeakers
Installation The UPL-1 and UPL-2 are are aligned for flat fre-
quency response in free field (no adjacent bound-
ary surfaces). Placing either unit next to a wall or
floor will cause the low frequencies to be exagger-
ated, requiring equalization to correct. Always
allow at least 6 inches clearance behind the
speaker for cooling airflow.
The UPL-1 and UPL-2 are fitted with four 3/8"-16
nut plates, two each on the enclosure top and
bottom. These may be used to attach the enclo-
sures to cables for hanging, or to a suitable sup-
port plate for mounting on a loudspeaker stand.
Each rigging nut plate is designed to support the
weight of a single cabinet.
Note. The UPL-1 and UPL-2 are not weather-
resistant, and should not be installed outdoors
where they may be exposed to the elements.
To protect from hazard of shock and compo-
nent failure, avoid rain or liquid spilled on the
amplifier chassis.
To avoid accidental disconnections, the UPL-1 and
UPL-2 cabinets are fitted with four tie-wrap an-
chors located at the four corners of the rear-
mounted amplifier chassis. Power and signal input
cables may be secured by inserting a plastic lock-
ing tie-wrap through any of these anchors, wrap-
ping it around the cable(s) and locking it in place.
