Instructions for using LD-Systems Pro Series Loudspeakers

Description

The speaker enclosures in the LD Pro Series have been developed as universal passive, or
two-way active systems for full-range operation. Eight versions are available:
LDP8-2 With 8" Bass chassis and 1" HF-driver, 80W RMS, 8
LDP8-2A As above, but with built-in amplifier 50 + 20W in 4 + 16
LDP10-2 With 10" Bass chassis and 1" HF-driver, 150W RMS, 8
LDP10-2A As above, but with built-in amplifier 100 + 25W in 4 + 16
LDPN12-2 With Neodymium 12" Bass chassis and Neodymium 1" HF-driver, 250W RMS,
8
LDPN12-2A As above, but with built-in amplifier 160 + 70W in 4 + 8
LDPN15-2 With Neodymium 15" Bass chassis and Neodymium 1" HF-driver, 300W RMS,
8
LDPN15-2A As above, but with built-in amplifier 160 + 70W RMS in 4 + 8 .
Recessed flanges make the cabinets suitable for mounting on speaker stands, but they can
also be flown thanks to the lashing points provided. A floor monitor bracket can be ordered
as an optional extra. All cabinets are manufactured from high quality plastic.

Placement

Indoors, you can place the cabinet however you see fit. Use the built-in flange for a speaker
stand, hang the cabinet from the flying system using the recessed threads provided in the top
of the cabinet (each of which is protected by a rubber cap when not in use) or use the
optional monitor stand.
Outdoors, you must ensure that the cabinet is placed so that it will be protected against direct
exposure to rain and water spray.

Connections

The passive versions of the cabinets are equipped with 2 Speakon jacks; the second jack is
used to loop-through the signal to the next cabinet.
The active version is first connected to the 230V (UK 240V) AC mains using a mains cable.
The following audio inputs are available:
LDP8-2A - Balanced Line In via XLR, balanced Microphone in via XLR, the input sensitivity
of both inputs can be adjusted using the adjacent Level control.
LDP10-2A and LDPN12-2A balanced Microphone in via XLR, unbalanced Microphone in
via jack, the input sensitivity of both inputs can be adjusted using the adjacent Level control.
LDPN15-2A has two microphone input channels.
The XLR Line in is also a balanced input. Unbalanced Line signals can be connected via
RCA/phono sockets. There are two (L & R) for a stereo signal, which are mixed together
internally to mono. The gain is also adjusted via the line in Level control. Of course, the line
and microphone inputs can all be used at the same time. The Master Volume determines
