1 DESCRIPTION

The VCC-64 allows up to 64 programmable channels and volume control (0-9). Usually installed

in local zones and connected via bus to the system, it offers source selection, volume control

and lock function.

FEATURES:

•Source selection (1-64)

•Volume setting for the zone (0-9) – 10 steps per change

•Automatic lock function

•It shows the identifier of the music source routed to the zone

•It shows the volume level assigned to the zone

•Lock activated indicator

•Connection of devices by bus mode

2 FUNCTIONING

The VCC-64 has a 2x8 character alphanumeric display where it shows the information related to

the zone of the PA system that is assigned.

2.1.1 Rest Mode

During the rest mode, the display will indicate the music source assigned to the zone, the

volume level (0-9) and the lock indicator.

User Manual: VCC-64

2.1.2 Active Mode

To unlock the device, press CH+ and then CH-. The lock indicator will disappear from the

display.

Once unlocked, press VOL+ to raise the volume level of the zone and VOL- to lower it. The

following table of equivalence shows the relationship between the volume indicated in the VCC-

64 and the gain associated to the zone.

Table 1 - Active Mode

To change the audio source assigned to the zone, press the buttons CH+ and CH-. The display

will show the change in the number of the source. The number displayed corresponds to the

number of the source in the PA system.

The audio source in the zone of the VCC-64 can be assigned remotely from the main PA

system's management or locally from the VCC-64.

The VCC-64 can select from any of the audio sources available in the system, up to 64. By

pressing CH+ or CH- we move from one to the next in a cyclic order.

The information relative to the audio sources that the VCC-64 will show, can be seen in the

following table.

2.1.3 Automatic Lock

The VCC-64 has an automatic lock that will be activated after 25 seconds from the last push of

a button. To activate the VCC-64 again, press CH+ and then CH-. The lock indicator will

disappear from the display.

2.2 Connection to the System

Figure 1 - Connections

2.2.1 Data Bus and Power Supply

The VCC-64 has two poles for data connection through RS-485 protocol. It has a power supply

input of 12V DC with a consumption of 1.2W (100mA). The connector is marked as J500. When

the equipment has a power supply, the LED indicator marked power will be on.

The maximum number of units connected to the same interface is 8. The maximum length

(considering all sections) is 1000 m.

The connection uses a female Eurobock type connector (included) of 4 pins and 3.81mm pitch.

The range of cable section for each pole of this connector is 0.14 →1.5mm2(30 →14 AWG)

2.2.2 Bus Address

The VCC-63 has a DIP-Switch to configure the address in the RS-485 bus. Every controller

assigned to the same zone should have the same address configuration. For different zones

different address should be assigned.

2.2.3 Cabling

The VCC-64 is connected to the system's interface through bus mode, and every VCC-64 will

be connected to each other. Only one VCC-64 has to be connected to the system's interface.

User Manual: VCC-64

8 Rev.0.3

The unit located closest to the system will be connected to the interface, and to the next VCC-

64. The last VCC-64 in the bus will not have any connection to a consecutive device.

3 PROBLEM SOLVING:

3.1 Blank Screen

If the display is blank, check the power supply. Verify that the wiring has been connected

according to chapter 2.2.1. If the power indicator light is on, reboot the system by disconnecting

the power and reconnecting it again. If, after restarting the system, nothing appears in the

screen then contact Technical Support of LDA.

If the power indicator is off, the device is not receiving power and therefore will not work

properly.

3.2 The Number of Sources and Volume Does Not Appear on Screen

If the number of sources and volume does not appear on screen, this is an indication to the

system that there is no connection. Restart the device by disconnecting the power and

reconnecting it again. If the problem persists and is not resolved, check the wiring as described

in section 2.2.

If, after performing these tests the problem persists, contact the support service of LDA.

4 MAINTENANCE INSTRUCTIONS

Generally, the equipment requires a reduced periodical maintenance.

The frequency of maintenance should be adjusted depending on the installation conditions of

the system.

Warning:

•Use only a soft, lint-free cloth to clean the system.

•Disconnect the device from any external power source.

•Disconnect all external devices.

•Keep it away from any liquid.

User Manual: VCC-64

9 Rev.0.3

•Do not use aerosol sprays, solvents or abrasives.

•Do not spray any cleaning products directly on the device.

Operation:

•Wipe the system with a damp cloth.
