VIO-L208 Cod. 420120268 REV. 1.0

INPUT, OUTPUT AND CONTROL SECTION

1. INPUT AND OUTPUT LINK (“Balanced audio”)

Input and output compatible with balanced XLR cables.

In particular, "Input" is used to connect with the audio signal coming from the mixer or from another loudspeaker,

"Output Link" is used to link the signal to the other modules of the line-array, in daisy-chain conguration.

2. AUDIO ATTENUATION

Allows adjusting the attenuation of the module using the input volume.

Before installing the line array, set at 0 dB.

4. DSP PRESET

Rotary for the acoustic setup of the line array.

It is advisable to use these controls (or the same parameters remotely via RDNet connection) to optimize the

acoustic behavior as a function of the number of modules and their aiming. An in-depth analysis on the use of

“SPEAKER COUPLING” and “HIGH FREQUENCY COMPENSATION” can be found in the “DSP PRESET PARAMETERS

AND REMOTE CONTROL” section.

3. INPUT AND NETWORK CONNECTION LINK RDNet

Section compatible with network cables with etherCON/RJ45 connectors.

In particular, "Data in" must be connected to devices such as RDNet Control 2 or Control 8; "Data Out" is used to

link the network to additional modules of the line array in daisy-chain conguration.

5. STATUS LEDs

LEDs relating to module operation. A table in next page summarizes the meaning of the different LEDs.

6. CONTROL LEDs

LEDs relating to module network operation (RDNet).

In particular, if "Link" is on the RDNet network is active and has acknowledged the device, if "Active" is ashing

there is data trafc, if "Remote Preset Active" is on all local control on the amplier panel are by-passed by the

RDNet remote control.

7. SERVICE DATA USB PORT

It is a mini-USB B port to be used only for product rmware update. For further information refer to "FIRMWARE
