Lencore Magnacast User manual

INSTALLATION
MANUAL
MAGNACAST SPEAKER

1) The Magnacast should be mounted with a slight downward angle
as shown below. The horn should never be mounted with the
opening facing up. Using the device in a manner contrary to these
instructions will void factory warranty.
Magnacast Downward Angle
2) The Magnacast comes with a junction box for speaker
connection. Speaker + should be wired into terminal block 1 and
Speaker –should be wired into terminal block 3. The Magnacast
is rated at a maximum input voltage of 45 VRMS (64 V peak).
Driving the unit beyond this voltage will void factory warranty.

3) The junction box comes pre-drilled with a ¼” pilot hole. The installer
must drill this hole to the correct size based on input conduit
connection (not included). (Note: After drilling, ensure all metal
shavings are removed from the box. Failing to properly seal this
connection could result in premature failure of the device and void
the factory warranty.)

Magnacast Vertical Beamwidth Reductions
4) The primary beam angle of the Magnacast is 70° x 80° @ 1 kHz.
Within the primary beam angle the user can expect to achieve the
full rated SPL. Outside of the primary beam angle, the device will
still be able to be heard but at a reduced output as depicted below.

MAGNACAST SINGLE UNIT MOUNTING OPTIONS
1) The Magnacast comes standard with eye bolts for hanging by
chains. Again, the unit should be mounted at a slight downward
angle with the mounting bracket up.
2) Optional mounting hardware is available to attach a single
Magnacast to a wall or pole. Hardware allows for incremental
adjustment both horizontally and vertically.

5) Wire directly into junction box as detailed in Section 1. Speaker +
should be wired into terminal block 1 and Speaker – should be
wired into terminal block 3.
MAGNACAST 4XUNIT MOUNTING OPTION
1) Mounting hardware is also available to mount four (4) Magnacasts in a
manner to create an omni-directional acoustic source. The kit
provides the hardware necessary to mount the unit to the top of a
pole up to 10” in diameter.

3) Drill a hole in the junction box. The location is indicated by the pilot
hole on the side. (Note: Hole size to match transformer/junction box
cable gland seal.) Remove the cabling provided with transformer/
junction box and install into Magnacast. Speaker + should be wired
into terminal block 1 and Speaker – should be wired into terminal
block 3.
4) Attach the pan/tilt bracket to the Magnacast mounting bracket.

5) Attach the pole mounts to the 4X mounting plate as shown below.
(Note: Leave fasteners loose until system has been attached to the
pole in step 6.)
6) Mount to pole and ensure the unit is level. Tighten all pole
fasteners, and then tighten the fasteners left loose in previous step.
(Note: Pole fasters not included.)

performance. Shown below are polar plots for recommended
configurations.
