HORIZON

PRODUCT TRAINING MANUAL

HORIZON is not just a speaker ...... it is a complete system, highly modular, infinitely versatile, with a sound concert pressure level and bandwidth.

It combines the simplicity and flexibility of installing a "point source" with the consistency, control and output of a line array

STRENGTHS

Modularity, Scalability:	Precise 90° x 20° single element coverage also allows the use of a single VHA 406A.Wide splay angle between cabinets (5° to 20°) to adapt and scale coverage and max output depending on the environment and audience.
Vertical and Horizontal:	System dispersion totally configurable.
Concert sound SPL & Bandwidth:	HORIZON system provide remarkable power, bandwidth and coherence, flexible and predictable coverage.Beautiful midrange voicing maintaining high outputs thanks to 4 x 6.5" custom woofers and 12" FBT engineered waveguide with 1.4" B&C compression driver.
Coherence:	Symmetrical driver arrangement with central waveguide for symmetrical and constant 90° dispersion pattern.
Plug and Play:	HORIZON system (top, flying sub and ground sub) have all the processing onboard on the internal DSP and is factory optimized to get the best out of each of the endless configurations.
Durable:	The rubber sides protect the cabinet from wear, keeping the astonishing look of the system over the time.
Integrated advanced hardware:	Prepared for mounting in horizontal or vertical arrays, the hardware is fully integrated into the cabinet and has only two anchoring points, for quick and easy installation; FBT engineered locking pins are permanently anchored in the structure, without the possibility of being lost and do not protrude from the sides of the structure.
Unique 3 way operation mode:	The VHA 112SA is a real plus of the HORIZON system; with the same cabinet and hardware of the VHA 406A, it can be used as subwoofer in so called "2 way + sub" configuration with a 50 - 110Hz bandwidth or as LF in "3 way" configuration with 50 - 230Hz bandwidth with the VHA 406A specialized to MF and HF. In this mode the VHA 112A and VHA 406A work as bigger real 3 way cabinet with 12" LF woofer, 4 x 6.5" MF and 1 x 1.4" HF, garantend higher dynamics and headroom but maintaining the modularity and simplicity of transport of a small cabinet.

APPLICATIONS

- Small to large rental, fixed installations, outdoor / indoor live events as main, frontfill and central cluster.

MARKET POSITION

VERTICAL VARIABLE CURVATURE ARRAY:

• Only vertical installation with 90° (typical) horizontal fixed coverage
• Narrow single element vertical directivity and max 10° inter-cabinet angle mean a lot of cabinet to cover wide vertical audience
• Complicated setup and hardware

CONSTANT CURVATURE ARRAY:

• Wide vertical single element coverage and 20° - 25° inter-cabinet angle mean few elements to cover entire audience at the expense of maximum output
• Limited application to short/medium throw

HORIZONTAL/VERTICAL VARIABLE CURVATURE ARRAY

Fill the gap between the two keeping the best of both!

• Horizontal and vertical installation mean maximum freedom coverage pattern selection to best fulfill the audience
- 5° to 20° inter-cabinet angle mean the possibility to cover the entire audience with few elements or with a hard rock concert amazing output!
- Infinite system configurations possibility thanks to a complete set of hardware accessories

SMALL CONFIGURATIONS

LARGE CONFIGURATIONS

APPLICATION QUESTION

• What mean '2WAY+SUB' and '3 WAY' configuration?

They represent two operating modes of the system, in particular the VHA406A and VHA112SA elements. In 2WAY+SUB, the VHA406A is used for LF and HF (2way) and the VHA112SA as a subwoofer with 50 – 110 Hz bandwidth. Of course the VHA112SA can be coadiuvated with the VHA118SA ground subwoofer to increase SPL and extend low frequency response. In this configuration the VHA112SA is not indispensable to the system that can be composed just by VHA406A and VHA118SA with full power bandwidth from 30 to 20KHz.

In 3WAY mode, the VHA406A is used as MF and HF, the VHA112SA is used as LF with crossover point at 230Hz. So both element work effectively same as 3way cabinet with increased dynamics, detail and headroom. The ratio between quantity of VHA406A and VHA112SA is strictly fixed to 1:1. Of course the VHA118SA can still be used as subwoofer to increase SPL and extend low frequency response.

- When VHA112SA can or must be used?

The HORIZON system is designed to work properly when composed with just VHA406A as top and VHA118SA as subwoofer. Anyway the VHA112SA is very helpful in some cases:

- As 'energy gap filler' between VHA406A top and VHA118SA subwoofer in high output application. In this case a ratio of 1 VHA112SA to two or three VHA406A is suggested.

- In flown application as subwoofer (in tandem with VHA118SA) to improve bass frequency consistency at far distance.

- As the only subwoofer of the system in application where only flown installation is mandatory. In this case, depending on the program reproduced, a ratio of 1 vha112SA to one or two VHA406 is suggested.

- In 3 WAY operation where VHA112SA with 1:1 ratio with VHA406A is mandatory

• VHA118SA and VHA112SA overlap in the 50-110Hz range when both are present on system, there is a risk of phase cancellation?

Onboard DSP preset, if properly configured, is designed to obtain perfect power summation from the two overlapping subwoofers when aligned to the same vertical plane. Of course, if they are installed on different vertical plane, some care must be taken to digitally realign the acoustic sources to audience. VHA118SA have a delay switch onboard that is helpful to cover most installations. Otherwise an external delay line must be use.

• What's the ration between VHA406A and VHA118SA?

Normal ratio for standard program is two VHA406A to one VHA118SA. For indoor with light or acoustic program 3 to 1 is more than sufficient. For live concert with high output levels outdoor we suggest 1:1 or 1:1.5 ratio.

- What's the maximum cabinet that can be flown on each flybar?

Vertical flybar VHA-F 406 can hung a maximum of 6 x VHA406A or VHA112SA (or a combination of the two) with 10 safety factor. Horizontal flybar VHA-FH 406-1 can hung a maximum of 5 x VHA406A or VHA112SA (or a combination of the two) with 10 safety factor.

AUDITORIUM / HOUSE OF WORSHIP

SYNOPTIC

SOLUTION

Horizontal array system, useful in case the height required for a vertical array configuration is not adequate, when it is important to have large vertical dispersion (90 °) and to control the horizontal dispersion accurately and according to the environment. This configuration is suitable for medium-sized environments where the audience is arranged on a number of levels and with a general music program. To increase the SPL at low frequencies, it is possible to add the VHA 118SA subwoofers. The subwoofers are in cardioid configuration to reduce the pressure on the stage by approximately 18dB in the 30 ÷ 100Hz range.

POWER SUPPLY 220 - 230V

For power supply VHA model features a Neutrik PowerCon

cable duplex with input and output.

CAUTION: never replace the plug of the power cord supplied since the power cord can only support a maximum current of 16A.

POWER SUPPLY 120V

If the total current demand does not exceed 15A use the power cable supplied.

If the total current demand is between 15A and 20A, user the power cable AWG12 SJT VW1 with plug rated current equal or greater than 30A.

THE CABLE AND THE PLUG MUST HOLD THE "UL" OR "CSA" CERTIFICATION.

The HORIZON system consists of three models:

• VHA 406A: 2-way bi-amplified speaker with 65Hz - 20kHz bandwidth (120Hz - 20kHz HP Filter ON)
• VHA 112SA: 12" 1-way amplified subwoofer with 50Hz - 120Hz bandwidth (40Hz - 120Hz con "LF Extension" ON)
• VHA 118SA: 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 guarantee 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 406A and VHA 112SA, two modes of operation are possible:

- 2 WAY + SUB SYSTEM: "2 WAY" refers to the VHA 406A model and "SUB" to the VHA 112SA model. In this mode the acoustic crossover is set to 110Hz (therefore outside the vocal range) 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 112SA and under 4 x VHA 406A. This mode works correctly with any permissible configuration of the HORIZON system.

- 3 WAY SYSTEM: The combination of VHA 406A and VHA 112SA is addressed to produce a 3-way speaker (LF+MF+HF) in which the VHA 112SA speaker forms the first way (LF) and the VHA 406A constitutes the two remaining ways (MF+HF). The acoustic crossover, in this case, is set to 230Hz (within the vocal range) 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 118SA 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 406A in full-range (HP FILTER OFF): for voice or music with limited energy content at low frequencies.
- VHA 406A (HP FILTER ON) + VHA 112SA in "2 WAY+SUB" or "3 WAY" configuration. The "LF EXTENSION" button can be activated on • VHA 112SA to obtain greater extension at low frequencies.
- VHA 406A (HP FILTER ON) + VHA 112SA in "2 WAY+SUB" or "3 WAY" configuration ("LF EXTENSION OFF" button) + VHA 118SA with a preset of your choice (VHA button 112SA 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 112SA and VHA 118SA. The "PUNCH" preset is not recommended.
- VHA 406A (HP FILTER ON) + VHA 118SA (VHA button 112SA OFF). In this configuration it is necessary to choose one of the first 4 pre-sets (A-B-C-D) for VHA 406A according to the number of speakers that compose the array, while it is forbidden to use the "E-F-G-H" pre-sets (see figure 1). For the VHA 118SA 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 button located on the VHA 406A 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 406A. 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 112SA and VHA 406A is fixed at 1:1. E.g. A configuration with 4 speakers must have no. 2 VHA 112SA models and no. 2 VHA 406A models. Furthermore, the two modules must respect a rule on their mutual positioning. (see fig.1)

HORIZON VHA 406A

Button for activating the low-cut filter device that only releases the highest frequencies of the "cut-off frequency". N.B. the command, in a 3-way configuration, is "bypassed".

HORIZON VHA 112SA

Activating this control extends the response to the low frequencies. TO BE USED EXCLUSIVELY WHEN THE VHA 112SA IS THE ONLY SUBWOOFER OF THE SYSTEM.

HORIZON VHA 118SA

Position the button in "YES" mode only when the HORIZON system also includes the VHA 112SA model; in this way, through the "all pass" filters, perfect phase alignment between the two subwoofers is guaranteed.
