PACKAGE CONTENT AND MAIN FEATURES

|
---|---

The package contains:

• VIO C (depending on the purchased model)
• Mechanical LP-1 link plug for cluster installation
• Power cable and fuse according to Country of use
• Paper documentation (quick-start guide, section 1 and section 2 warnings-warranty)

The figure shows:
A – Rear handles (one at the top, one at the bottom)
B – IR sensors
C – Upper mechanical fixing seats (one on each side)
D – Side handle, one on each side
E – Lower mechanical fixing seats (one on each side)
F – LEDs for remote positioning verification with Aurora Net
G – Rubber feet (2 at the top, 4 on the side)
H – Seat for LP-1 transport
I – Amplification section
LP-1, which can be housed in position H for transport, is mandatory for cluster construction. Please refer to the relevant chapter: CLUSTER INSTALLATION AND LP-1 ACCESSORY.

COVERAGE (HORIZONTAL CLUSTER)

The horizontal sound coverage of a speaker for the 3 models is:
22.5°. The coverage in the horizontal clusters can be assumed to be the sum of the individual coverages (e.g. clusters of 4 VIO C units side by side: 90°).
The vertical coverage is asymmetrical and varies according to the model.
VIO C12-C212: +20° -35°.
VIO C15: +15° -30°.
In addition to the use in horizontal 1-layer clusters, VIO C12 AND
VIO C15 can be used in 2-layer clusters.
In this case, as shown in the figure, the speakers are upside down in the upper layer: therefore, thanks to the matching of the acoustic horns, the vertical coverage can be as follows:
VIO C12 – 2-layer clusters – V: 70°
VIO C15 – 2-layer clusters – V: 60°
DIMENSIONS
The VIO C series has been designed with the intent to optimize weight and dimensions in relation to performance.
For a quick comparison of the 3 models, the overall dimensions are the following:
VIO C12 – 379 mm (w), 787 mm (H), 495 mm (D)
VIO C15 – 436 mm (W), 892 mm (H), 630 mm (D)
VIO C212 – 379 mm (W), 1132 mm (H), 495 mm (D)

INFORMATION ON POWER DAISY CHAIN
In the 220-240V~ range of use, the maximum number of VIO C linkable speakers is 1+4.
In the 100-120V~ range of use, it is 1+3 for all models.

ACCESS TO PARAMETERS AND MENUS

Use the control panel button to access all the speaker parameters displayed on the screen. Pressing this button allows you to change a parameter or confirm it, rotating it allows you to select the value or increase/ decrease it.
SWITCH-ON AND CLUSTER RECOGNITION
The initial page is shown upon switch-on (FIG.1).

Once the cluster has been recognized, there is a simplified procedure to control it entirely from a single control panel.
In particular, if the IR sensors detect a speaker next to the one you are operating on, the relevant symbol will be highlighted (FIG. 2)

If the IR sensors detect a speaker above the one you are operating on, that speaker will be considered as a slave unit by default, and its display will show the relevant screen page (FIG.3).

In this case, if you change a parameter on the master, all slaves (next to it and above) in the cluster will start flashing.
Press the button on the panel of each slave once to confirm this parameter on all elements of the cluster.

MAIN PARAMETERS
In sequence, the user can access the following screen pages on the control panel of a master (in figure 4a, 4b, 4c, 4d respectively):

• LEVEL (0 -12dB / MUTE)
• HPF (High Pass Filter) (60 120 Hz / FLAT)
• DELAY (0 – 10 ms)
• MENU

In particular, MENU allows accessing:
-EXIT (to quit the menu)
-CLEAR CONFIGURATION (to reset local parameters)
-SPEAKER TEST ( to immediately test impedance on the HF or LF channel)
-SAVE/RECALL MENU (to save/recall settings on VIO C)
-OPTION
If the speaker is a slave unit, only OPTION – MENU – SPEAKER TEST will be displayed.
In particular, OPTION allows acting on the following parameters:
-contrast (to adjust contrast)
-stand-by (to enable and set an idle time after
which the speaker sets to standby mode)
-restore
-force master (to force a slave to become a master)

REMOTE CONTROL AND RDNET CONNECTION (AURORA NET)

All speaker and cluster parameters can be adjusted with the remote control, once the RDNet connections have been properly made, using the AURORA NET software. When using the remote control, the local controls on the speaker are bypassed. Using this software, you can control a larger number of parameters (for more information, please refer to the AURORA NET user manual).
In the case of remote control and connection with AURORA NET, the DISPLAY shows a screen page with the software logo locally on the speaker (FIG. 5).

LP-1 AND CLUSTER INSTALLATION

The LP-1 link plug is required for creating VIO-C clusters. It is equipped with 2 buttons X for quick coupling. The number of required LP-1 link plugs varies depending on the number of elements and whether the installation is in flown or stacked configuration. Two people are required to connect the LP-1, following the sequence below:

1. align the pins to the holes of 2 speakers in the mechanical seats C or E, as shown in the figure below
2. press and hold the buttons X down to insert LP-1
3. release the buttons X

The figure at the top right side shows the possible connection positions in a cluster: T (top), E (external), I (internal), L (lower). According to this nomenclature, depending on whether the installation is with one or two layers and whether it is flown or stacked, the table below shows the LP-1 numbers required for correct installation.

STACKED 1-LAYER CLUSTER

FLOWN 1-LAYER CLUSTER

STACKED 2-LAYER CLUSTER

FLOWN 2-LAYER CLUSTER

CLUSTERIN FLOWN AND STACKED CONFIGURATION AND ACCESSORIES
