8. Do not install the device near radiators, heat accumulators, ovens or other sources of heat. Make certain that
the device is always installed so that is cooled sufficiently and cannot overheat.
9. Do not place open sources of ignition, e.g., burning candles, on the device.
10. Do not cover ventilation slots.
11. Do not operate the device in the immediate vicinity of water. Do not expose this equipment to combustible
materials, liquids or gases.
12. Please make certain that dripping or splashing water cannot get inside the device. Do not put objects filled
with fluids, such as vases or drinking vessels, on top of the device.
13. Make certain that objects cannot fall into the device.
14. Use the device only with accessories with which the manufacturer intends the device to be used.
15. CAUTION: If this device has a mains connector equipped with protective earth, it must be connected to a
mains socket with a protective ground connection. Never disable the function of the protective ground connection
of the included power cord.
16. Do not turn on the device immediately if it was exposed to strong temperature fluctuations (for example after
transportation). Moisture and condensation may damage the device. Leave the device switched off until it has
reached room temperature.
17. Do not open the device and do not make any changes to the device.
18. Before connecting to mains power, make certain that the mains voltage and the mains frequency are the
same as the operating values of the device (see type label). If the device is equipped with a supply voltage selec-
tor switch, make certain that the values of the device match the values of the mains power before connecting.
If the plug on the included cord does not fit your mains outlet, contact your electrician.
19. Make certain that the power cord is not stepped on. Protect the power cord against pinching, especially at
the device plug and the power plug.
20. In order to prevent damage or accidents, for example, due to tripping hazards, check all connections once
you have connected the device.
21. When connecting the device, make certain that the power plug remains readily accessible.
Always pull out the power plug when the device is not in use or when you clean the device. Disconnect the
power cord by pulling the plug not the cable.
22. Avoid switching the device on and off at short intervals, because it may shorten the durability of the device.
23. IMPORTANT: Replace fuse only by fuse of same type and rating! If fuse blows repeatedly please contact
authorized service center!
24. In order to disconnect the device completely from the mains voltage, the power plug must be unplugged.
25. If your device is equipped with a Volex power connector, the matching Volex device plug must be unlocked
in order to disconnect it. This also means that a tug on the power cord can pull the device out of place, thus
causing personal injuries and/or property damage. Thus please make certain to route your cables carefully.

CAUTION
RISK OF ELECTRIC S HOCK
DO NOT O PEN
CAUTION:
To reduce the risk of electric shock, do not remove cover (or back). No user serviceable parts inside. Refer
servicing to qualified personnel.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the
user to the presence of uninsulated “dangerous voltage” within the product´s enclosure that may be
of sufficient magnitude to constitute a risk to persons.
The exclamation mark within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.
CAUTION! HIGH VOLUME!
You will operate this transmission system for professional use. Therefore the commercial use of this equipment
is liable to the rules and regulations of the Accident Prevention & Insurance Association of your industry sector.
Adam Hall as a manufacturer is bound to inform you formally about the existence of eventual sanitary risks.
Risk of hearing damage due to prolonged exposure to excessive volumes: The loudspeaker is easily capable of
generating sound pressure levels (SPL) sufficient to cause permanent hearing damage to performers, production
crew and audience members. Caution should be taken to avoid prolonged exposure SPL in excess of 90 dB.
DESCRIPTION:
The LD PRO series of speaker cabinets are designed as universal two-way systems for full-range operation.
Eight versions (4 passive and 4 active) are available:
• LDP82 with a 8" bass chassis and 1" HF compression driver, 100 W RMS, 8 Ω
• LDP82A, like LDP82, but with built-in bi-amping amplifier 80 + 40 W RMS
• LDP102 with a 10" bass chassis and 1" HF compression driver, 150 W RMS, 8 Ω
• LDP102A, like LDP102, but with built-in bi-amping amplifier 140 + 40 W RMS
• LDPN1222 with a 12" bass chassis and a 1" HF compression driver, 250 W RMS, 8 Ω
• LDPN122A2 , like LDPN1222, but with built-in bi-amping amplifier 190 + 60 W RMS
• LDPN1522 with a 15" bass chassis and a 1" HF compression driver, 300 W RMS, 8 Ω
• LDPN152A2 , like LDPN1522, but with built-in bi-amping amplifier 220 + 60 W RMS
Decisive modifications and improvements have once again been made to the 12" and 15" versions in the LD
Pro series, which encompasses four active and four passive models. In addition, a switchable bass boost was
integrated in the 12" and 15" active versions, which has a positive influence on the sound in the LF range at
low to moderate volumes. Now as ever, all four models are manufactured with the same time-tested, rugged
cabinets. The active versions still operate in bi-amping mode, which ensures high operational reliability, and
boast features that are unique in this price class. There are now wall brackets in addition to the optional monitor
feet available.
Recessed flanges make the cabinets suitable for mounting on speaker stands, but they can also be flown thanks
to the lashing points provided. Optionally, plastic feet that permit simple use of the cabinet as a floor monitor can
be ordered separately. All cabinets are manufactured of high-quality plastic.
SETUP
Indoors, you can position the cabinet however you see fit. Use the built-in flange for a speaker stand, the
recessed threads on the top of the cabinet (each covered with a rubber cap) for flyware, or the optional monitor
stand. Outdoors, you must ensure that the cabinet is protected against direct exposure to rain and water spray.

The passive versions of the cabinets have 2 Speakon compatible sockets; one socket is used for looping through
the signal to the next cabinet. The active version is first connected to the 230 V AC power mains with a power
cord. The following audio inputs are available:
LDP82A, LDP102A, LDPN122A2 and LDPN152A2 - balanced line input via XLR and unbalanced line input via
2 cinch sockets (RCA), balanced microphone input via XLR and unbalanced microphone input via 6.3mm TRS
plug. The sensitivity of each can be adjusted using the adjacent level control.
The LDPN152A2 has two microphone inputs with separate volume controls.
The XLR line input is balanced. Unbalanced line signals can be connected via the RCA sockets. There are two
connectors (L & R) for a stereo signal that is mixed down to mono internally. The volume is determined by the
adjacent level controls. Of course, the line and microphone inputs can be used at the same time. The master
volume is controlled by the third volume control below the other two. A shared 2-band tone control affects treble
and bass. A bass boost switch on the LDPN122A2 and LDPN152A2 additionally permits a boost of 3 dB @ 100
Hz (LDPN122A2) and 6 dB @ 100 Hz (LDPN152A2). At high volumes, it is advisable to deactivate the bass boost,
because otherwise the power amplifier enters the clipping range sooner.
Before turning on the unit with the power switch (the green power LED serves as an indicator lamp), all level
controls should be set to the MIN position. Otherwise, connected microphones may cause unintended feedback.
Start with the tone controls in the centre position. The levels of the various sources are balanced with one
another using the associated level knobs; the master volume is determined with the third level control (master
volume). The red clip LED lights up to indicate when the amplifier reaches the clipping range. This should be
avoided. If you connect mains-powered instruments that are grounded by a protective contact to the inputs of
the active cabinet, a ground loop may result due to double grounding. You can eliminate this low-frequency hum
by activating the ground-lift switch. All cabinets have a blue signal LED on the front which lights up as soon as a
signal is connected to the cabinet.
