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.

1MICROPHONE INPUT
Balanced XLR/jack microphone input
2GAIN MICRO
Adjust the input sensitivity of the microphone
input with this gain control. Please note that
microphones that require phantom power
(condenser microphones, for example) will not
work on these inputs because they do not supply
phantom power.
3LINE INPUTS
Balanced XLR/jack mono line input.
4LINE INPUTS
Unbalanced stereo RCA line inputs.
5GAIN LINE
Adjust the input sensitivity of the line input with
this gain control.
6LINE OUTPUTS
Balanced XLR and jack mono outputs. The mixed
input signals are split before the power amplifier
unit and sent to this output. You can use this
output, for example, to drive additional active
speakers or amplifiers with the mixed input
signals.
Important: This output signal is sent before the
master tone control and the master volume, so
it is unaffected by these settings.
7VOLUME MASTER
Use this control to adjust the overall volume of the
power amplifier.
8TREBLE
With the treble control, you can boost or decrease
the treble in the output signal by 12 dB.
9BASS
With the bass control, you can boost or decrease
the bass in the output signal by 12 dB.
The bass boost switch on the LDPN122A2 and
LDPN152A2 additionally permits a boost of 3
dB @ 100 Hz (LDPN122A2) and 6 dB @ 100
Hz (LDPN152A2).
10 POWER / CLIP
The power LED lights up green when the unit is
on. The red clip LED starts to light up when the
amplifier overloads, in other words, when signal
modulation reaches the clipping range. You should
avoid constant illumination of this LED by reducing
the master volume (control no. 7 in the picture)
until the clip LED goes out.
11 GROUND-LIFT SWITCH
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 the
resulting low-frequency hum by activating the
ground-lift switch.
12 AC INPUT
This power socket is used to connect the power
cord.
