INTRODUCTION
Thank you for purchasing a NEXT HFA112 Digital Active system. This manual will
provide you with useful and important information about your HFA112 element. Please
devote some time reading this manual, and keep it at hand for future reference. NEXTProaudio is concerned with your safety and well-being, so please follow all instructions
and heed all warnings. Also, a better understanding of some specific features of the CX
Series system will help you to operate it to its’ full potential.
UN PA CK IN G
NEXT HFA Series systems are built in Europe (Portugal) by NEXT-Proaudio,
according to the highest standards and thoroughly inspected before they leave the
factory. When unpacking your HFA112, examine it carefully for any signs of possible
transit damage and inform your dealer immediately if any such damage has occurred.
It is suggested that you retain the original packaging so that the HFA112 can be
repacked in the future if necessary. Please note that NEXT-Proaudio and its’ authorized
distributors cannot accept any responsibility for damage to any returned product through
the use of non-approved packaging.
HFA SERIES OVERVIEW
The HFA speaker series are fully powered PA systems, designed to deliver high output
and dynamics, extreme linearity and fidelity for unrivalled performance at a very
competitive price.
Entirely manufactured in Portugal, the HFA speaker series uses superb quality custom
made components, loading birch plywood enclosures coated by a scratch resistant
textured paint to assure an outstanding performance and durability.
The integration with the new DPAmplifier modules with up to 1650 Wrms, and the
advanced digital signal processing, set a new standard for distortion, noise and thermal
efficiency. A surprisingly simple handling concept lets you plug in and play straight away.
Configure the system by selecting the right preset and let the system do the rest.
Containing an asymmetric horn that ranges from 50º in the horizontal far-field to 100º in
the horizontal near-field and 50º vertical, fully rotatable, means you can use it either
vertical or on it’s side and still maintain the same directivity pattern.

SAFETY FIRST
Please pay close attention to this chapter. Failure to comply with these
instructions may result on injury or death.
HFA Series systems are capable of producing extremely high sound
pressure levels and should be used with care. Hearing loss is cumulative
and can result from levels above 90dB if people are exposed for a long
period. Never stand close to loudspeakers driven at high levels.

HFA112 AMPLIFIER
The HFA112 as all HFA series models, was designed
to achieve a simple to use and deploy versatile
system. The HFA112, like all HFA series models, is
prepared to be completely plug’ n play, having
already six pre-determined configurations that cover
almost all situations. But if you’re not happy with
any of those, there are also two available user
defined configurations, which can be used to adapt
the system to your needs using the Next
SOUNDWARE1 software and the supplied RS485 to
USB converter.
Here is a brief description of the amplifier panel:
1- Signal input
2- Level adjustment
