PRO DG SYSTEMS IS NOT RESPONSIBLE OF ANY DAMAGE OF THE SYSTEM CAUSED BY A MANIPULATION, ADJUSTMENT, OPTIMIZATION OR REPARATION REALIZED BY NO-AUTHORIZED PERSONAL BY PRO DG SYSTEMS
- High loudspeaker levels can cause hearing damage, it must avoid the direct contact with loudspeakers operating at high levels, Dtherwise it must use hearing protectors.
MAIN CONNECTION:
- The system is designed for continuous operation
- The set operating voltage must match the local mains supply voltage.
- The unit has to be connected to the main via the supplied power unit or power cable.
- Power unit: never use a damaged connection lead. Any type of damage must be fixed.
- Avoid connection to the mains supply in distributor boxes together with several other power consumers.
- The plug socket for the power supply must be positioned near the unit and must be easily accessible.
PLACE OF SITUATION:
- The system should stand only on a clean and totally horizontal surface.
- The system must not be exposed to any type of vibration during its operation.

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.

In Pro DG Systems we know that making high quality speakers is an important
part of our job. Then, offering the warranty of using speakers properly is
another part which is also fundamental in our job. Good tools make the
difference for an optimal use of the system.
With Ease Focus V2 prediction software for IT 112 PA we can design different
configurations between systems and simulate their behavior in different places
and circumstances like obtain information of: coverage, frequency, SPL and
general system behavior in an easy and comfortable way. It is easy to handle
and we offer training courses for Pro DG Systems users. Click here to redirect
