antenna or cable system is connected to the product,
be sure the antenna or cable system is grounded so
as to provide some protection against voltage surges
and built-up static charges. Article 810 of the National
Electrical Code, ANSI/NFPA 70, provides information
with regard to proper grounding of the mast and
supporting structure, grounding of the lead-in wire
to an antenna discharge unit, size of grounding
conductors, location of antenna-discharge unit,

Controls and Features
Audio® - - DLT-15A - Instruction Manual Page 6
Rear Panel:
Rear Panel Controls and Features
1. BALANCED XLR/1/4” COMBO LINE INPUT – This connection is designed to accept a balanced line input signal from a mixer or other line level device with a balanced output jack. Use a
balanced cable when the signal cable length exceeds 15 feet, this will reduce excessive signal
loss. Be sure to connect only line level input devices such as mixers and tape machines to this
2. XLR PARALLEL OUTPUT JACK – This jack is used to send the incoming line level signal from
either of the Line Level Inputs Jacks to another DLT-15A or other line level input jack such as
a mixer or power amp.
3. POWER LED - This LED will be lit when you switch on the power.
4. LOW CUT SWITCH 5. LINE LEVEL INPUT VOLUME – This knob is used to regulate the output signal of the line level
source connected to the Line Level Input Jack (1).
TREBLE CONTROL – This knob is used to adjust the amount treble applied to the output signal. The maximum amount of treble gain is +15dB and the maximum amount of treble decrease
is -15dB. Turning the knob in a counter-clockwise direction will decrease the amount of treble
applied to a channel signal, turning the knob in a clockwise direction will increase the amount
of treble applied to a channel signal.
MIDRANGE CONTROL - This knob is used to adjust the midrange levels applied to the output
signal. The maximum amount of midrange gain is +12dB and the maximum amount of midrange decrease is -12dB. Turning the knob in a counter-clockwise direction will decrease the
amount of midrange applied to a channel signal, turning the knob in a clockwise direction will
increase the amount of midrange applied to a channel signal.
BASS CONTROL – This knob is used to adjust the amount bass applied to the output signal.
The maximum amount of bass gain is +15dB and the maximum amount of bass decrease is
-15dB. Turning the knob in a counter-clockwise direction will decrease the amount of bass applied to a channel signal, turning the knob in a clockwise direction will increase the amount of
bass applied to a channel signal.
6. VOLTAGE SELECTOR - Because power supplies vary from location to location we have incorporated a selectable voltage switch. This switch can select a voltage input of 120v~60Hz or
230v~50Hz. Always disconnect the power plug before changing the voltage.
7. MAIN POWER INLET – This connector is used to supply main power to the unit via the
included detachable power cord. The power connection uses an I.E.C. type connector, use
only the supplied polarized AC power cord. Use only a power cord that matches this type
of connection. Be sure to only connect this unit to a power outlet that matches the printed
power label on the unit. Never use a power when the ground prong has been removed or
broken off. The ground prong is used to reduce the risk of electrical shock in case of an electrical short. This cord is designed to fit in one direction only. Do not attempt to force a cord
if it does not fit, be sure the cord is being inserted properly.
8. MAIN POWER SWITCH – This is the main power ON/OFF button. A green LED directly above
the power switch will glow indicating power is ON. Before main power is applied, be sure you
have made all connections to the speaker. Remember to avoid damaging pops to the speakers, the mixer is turned on first and turned off last.

FUSE HOLDER – This housing stores the 3.15 amp GMA protective fuse. Always replace with
the exact same type fuse, unless otherwise instructed, by an authorized American Audio®
service technician. Replacing with any other type of fuse than that of the recommended fuse
will void your unit warranty.

Horn Rotation
The DLT-15A is equipped with a rotatable high frequency horn. The horn can be turned 90 degrees
when a differnet dispersion is desired; i.e. when rigging the speaker horizontally. Carefully follow the
directions below to rotate the horn.
1. Start by removing the 6 phillips screws located on each side, that hold
the grille in place.
2. Carefully remove the grille from the speaker.
DO NOT remove it completely! Seperate it
enought to disconnect the Clip LED wire. See
Step 3.
3. Slip your hand in between the grille and speaker and disconnect the Clip LED wire.
4. Once you have disconnected the wire, remove the grille completely to access the horn. Unscrew and remove the 8 phillips
screws that hold the horn in place.
5. After unscrewing and removing the screws, carefully and gently pull
the horn out of the housing (not all the way) and rotate the horn 90 degrees.
6. Once you have rotated the horn, replace the scews that secure the
horn, connect the clip LED wire, and secure the grille into place.

Mounting Options
Pole Mounting – The DLT-15A also include a pole mount option. The
pole mount socket located on the bottom of the speaker may be used
to secure the speaker to a speaker tri-pod, such as the American Audio®
SPS-1B as illustrated on the left. Always be sure to follow the guidelines
listed below when pole mounting your speaker;
• Always be sure the stand is designed to support the weight of
the speaker
• In outdoor situations that are prone to windy conditions and
strong wind gust, be sure to use sandbags as additional tri-pod
support, this will greatly reduce the risk of tipping
• Do not stack speakers on top of each other when mounting on
a tri-pod. Only one speaker should be mounted to a tri-pod at one
• Always position the tri-pod legs away from foot traffic
• Extend the tri-pod legs to their fully extended position to avoid
accidental tipping
• Observe and follow all safety guidelines and regulations specified
by the tri-pod’s manufacturer
• Be sure the tri-pod is situated on a flat, level, and stable surface
• Always tighten all tri-pod locks.
