Rigging and Electrical Safety
DANGER: The loudspeakers described in this manual are designed
and intended to be suspended using a variety of rigging hardware,
means, and methods. Installation of loudspeakers should only be
performed by trained and qualied personnel. It is strongly recommended
that a licensed and certied professional structural engineer approve the
mounting design. Severe injury and/or loss of life may occur if these products
are improperly installed! All electrical connections must conform to applicable
city, county, state, and national (NEC) electrical codes.
DANGER: It is possible to experience severe electrical shock from a
power amplier. Always make sure that all power ampliers are in the
“OFF" position and unplugged from an AC Mains supply before
performing electrical work.
IMPORTANT: All electrical installation connections for loudspeaker
lines are subject to all applicable governmental building and re
codes. The selection of appropriate electrical hardware to interface
with the loudspeaker lies solely with the installation professional. Biamp
recommends that an appropriately licensed engineer, electrician, or other
qualied professional identify and select the appropriate conduit, ttings, wire,
etc. for the installation.
DANGER: The output power capabilities of audio ampliers present a
danger to installers. To minimize the risk of electric shock from
loudspeaker connecting cables, conrm that the power ampliers are
turned “o" before connecting loudspeaker cable(s) to the loudspeaker or
amplier. Always follow local electrical codes and proper electrical safety
procedures.
WARNING: After wiring the amplier(s) to the loudspeaker(s), rst
power-up all devices that are upstream of the amplier, such as
mixers, equalizers, compressor/limiters, etc., before powering-up the
amplier. This is to avoid passing any clicks or pops that may originate in the
upstream devices to the loudspeakers. The amplier should initially be
powered-up with its gain controls turned all the way down. After making sure
that a continuous signal is present, such as a CD playing, slowly raise the level
of the gain controls to establish that the wiring has been installed correctly.
Only then should the loudspeaker be operated at normal output levels.
Wiring and Electrical Safety
All standard paging horns come with attached SJOW-rated input cables
(length 1m [3.3']). The cable exits the enclosure through a weather-resistant
nut. The other end of the cable is un-terminated. The designer must account
and compensate for cable losses between the amplifier and the loudspeaker
system. Refer to this article on Cornerstone for more information on cable loss
calculations. Do not remove the rear enclosure or tamper with the cable nut,
as this will compromise the weather integrity of the enclosure. Please contact
the Customer Support for additional assistance (email: support@biamp.com)
Wire the loudspeaker. A typical installation method is to bring the cable
into a junction box (J-box). Connections within the J-box may be made with
appropriate wire connectors. Terminate per your local electrical code or
requirements.
NOTE: Be sure to read the loudspeaker safety guide included in
the carton with the loudspeakers.

INSTALLATION
H10-G / H20-G / H30LT-G Horn Loudspeakers
These installation instructions apply to the H10-G, H20-G, and H30LT-G. Each loudspeaker comes
with an attached stainless-steel U-bracket for easy surface installation. The installer must provide
the appropriate hardware for the application. The horn and cable egress are watertight and may be
installed indoor or in outdoor applications.
1. Determine where the loudspeaker is to be installed.
2. Attach the loudspeaker to the structure or surface using the holes in the U-bracket (hardware not
provided).
NOTE: It saves time to adjust the tap setting before installation. See page 4.
3. Attach a safety cable (not shown) to one of the unused holes in the U-bracket (refer to safety
note at the bottom of this page.
NOTE: The U-bracket can be removed and pre-installed. Reserve the hardware for reattachment of the
horn.
4. Aim the loudspeaker to the desired angle and tighten the bolts on either side to hold it in place.
Figure 4. Position horn
NOTE: The safety cable and associated hardware are not included. Consult all applicable codes for your application.
Confer with a structural engineer for the appropriate cable / hardware for the load, application, and locale. If required,
the safety cable must be secured to a suitable load-bearing point separate from the array mounting, with as little slack as
possible, so as not to develop undue kinetic force if the primary mount were to fail.

SET LOUDSPEAKER TAPS
1. Remove the small black cap at the back of the horn to access the
tap switch as shown in Figure 5.
2. Use a small at screwdriver to turn the shaft to the appropriate
setting.
3. Replace the cap and make sure that it is fully seated to ensure
weather-resistance.

WIRING
The loudspeaker comes with an attached cable with 2 conductors white (+) / black (–) as seen below
in Figure 7.
Figure 7. Wire / cable
1. Route the cable to a junction box (J-box). Outdoor installations should utilize weatherproof boxes
and connectors to consistent operation.
2. Connect the cable in the J-box with barrel-type crimp connectors, wire nuts, solder and heat-
shrink, or terminal strips.
NOTE: Biamp recommends using barrel-type crimp connectors that are crimped with a forged
crimp or a ratcheting tool, as this method, when properly executed, results in a gas-tight
connection that is easy to accomplish.
3. Terminate connections per the local electrical requirements.
4. After all of the horns are installed and connected to the appropriate DSP/amplier equipment,
power and test the system.
Amplier power per channel must be higher than total power of all speakers on that channel.
