Introduction

This manual has been designed to help all the users of the system IT 112 PA of Pro DG Systems to its correct use as well as for the understanding of the benefits and versatility of the same. IT 112 PA is a passive multipurpose system totally designed, assembled and optimized in Spain.
IT 112 PA
Totally designed, manufactured and optimized in Spain. 
Description
IT 112 PA is a 2-way multipurpose passive system equipped with one (1) speaker of 12″ in a tuned enclosure. The HF section has one (1) compression driver of 1/4”, coupled to one (1) rotating diffuser of 80×50. IT 112 PA incorporates multifunction switch to work with its own crossover or biamplied. It is perfect to be used as P.A, frontfill and sidefill with or without subwoofer, as portable system or permanent installation. It can be used individually and horizontally stacked or flown with two or more units together as X-Array system of constant curvature, or vertically adapted thanks to its special flight hardware to work as a Line Array system as well.

MOUNTING INFORMATION

Baffle cutout diameter:
– Front mount| 278 mm (10,94 in)
Depth| 131 mm (5,16 in)
Net weight| 5,5 kg (12,12 lb)

• T-S parameters are measured after an exercise period using a preconditioning power test. The measurements are carried out with a velocity-current laser transducer and will reflect the long term parameters (once the loudspeaker has been working for a short period of time).
  The Xmax is calculated as (Lvc – Hag)/2 + (Hag/3,5), where Lvc is the voice coil length and Hag is the air gap height.
