The HORIZON system consists of three models:
• VHA 406ND: 2-way bi-amplified speaker with 65Hz - 20kHz bandwidth (120Hz - 20kHz HP Filter ON)
• VHA 112SND
: 12” 1-way amplified subwoofer with 50Hz - 120Hz bandwidth (40Hz - 120Hz con “LF Extension” ON)
• VHA 118SND : 18” 1-way amplified subwoofer with 30Hz - 100Hz bandwidth
The system is very versatile and is available in a variety of configurations to better adapt to the requirements of use; the pre-sets are designed to guaran -
tee correct alignment of the system in amplitude and phase as the configuration used varies. It is very important to correctly configure all the controls
in the speakers in order to avoid seriously compromising the final result .
When the system includes
VHA 406ND
and
VHA 112SND
, two modes of operation are possible:
• 2 WAY + SUB SYSTEM : “2 WAY” refers to the VHA 406ND model and “SUB” to the VHA 112SND model. In this mode the acoustic crossover is set to
110Hz and the system is assimilated to a “SAT+SUB”. The ratio between SUB and SAT can be chosen between 2:1 and 1:3 depending on how much
energy is required below 110Hz and the physical distance between SUB and SAT can also vary accordingly depending on the number of SAT and
SUB that make up the horizontal and vertical array. For example, an array can be configured with 2 x VHA 112SND and under 4 x VHA 406ND. This
mode works correctly with any permissible configuration of the HORIZON system.
• 3 WAY SYSTEM : The combination of VHA 406ND and VHA 112SND is addressed to produce a 3-way speaker (LF+MF+HF) in which the VHA
112SND speaker forms the first way (LF) and the VHA 406ND constitutes the two remaining ways (MF+HF). The acoustic crossover, in this case,
is set to 230Hz and the system must respect precise rules in terms of the ratio of the two speakers (which must be strictly 1:1) and the distance of
the acoustic centres ( which must be aligned vertically or horizontally and as close as possible). This configuration was conceived above all to have
the maximum SPL and “headroom” in large configurations where the 12” woofer is used in all its potential to provide the system with the necessary
energy supply on the LF range.
N.B. Both configurations can be accompanied by the VHA 118SND which is the “actual” subwoofer of the system and is required in the vast majority of
“live” and “sound reinforcement” applications to provide the correct impact at low frequencies.
The possible combinations of speakers are:
• VHA 406ND in full-range (HP FILTER OFF): for voice or music with limited energy content at low frequencies.
• VHA 406ND (HP FILTER ON) + VHA 112SND in “2 WAY+SUB” or “3 WAY” configuration. The “LF EXTENSION” mode can be activated on VHA
112SND to obtain greater extension at low frequencies.
• VHA 406ND (HP FILTER ON) + VHA 112SND in “2 WAY+SUB” or “3 WAY” configuration (“LF EXTENSION OFF” mode) + VHA 118SND with a
preset of your choice (mode VHA 112SND ON). In this configuration the preset “INFRA” offers the highest quality and timbre neutrality, while the
“ORIGINAL” or “DEEP” pre-sets offers the maximum SPL ensuring the overlap between VHA 112SND and VHA 118SND. The “PUNCH” preset is
not recommended.
• VHA 406ND (HP FILTER ON) + VHA 118SND
(mode VHA 112SND OFF). In this configuration it is necessary to choose the presets for VHA 406ND
according to the number of speakers that compose the array, while is not allowed the use of presets in 3-way system configuration. For the VHA
118SND in general the “INFRA” pre-set is not recommended while it is possible to choose from among the others available as required. The INFRA
preset can only be used together with the “HP FILTER” OFF located in the VHA 406ND speaker which ensures a uniform response in the crossover
area, even if energetically, at high volumes, the system may suffer a drop in performance in the 75Hz - 105Hz range, due to the limitation of the VHA
406ND. The PUNCH pre-set offers a fast and high impact bass on 60 - 90Hz, particularly suitable in “live” mode.

The ratio between the quantities of VHA 112SND and VHA
406ND is fixed at 1:1.
E.g. A configuration with 4 speakers must have no. 2 VHA
112SND models and no. 2 VHA 406ND models.
Furthermore, the two modules must respect a rule on their
mutual positioning. (see fig.1)

Select “YES” mode only when the HORIZON system
also includes the VHA 112SND model; in this way,
through the “all pass” filters, perfect phase alignment
between the two subwoofers is guaranteed.
