SAFETY PRECAUTIONS

• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.
• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or cautions regarding safety.
• After reading, keep this manual handy for future reference.
• This equipment is not suitable for use in locations where children are likely to be present.
• An equipment installer and the person in charge of maintenance are required to fully understand the functions and structure of this unit, then be aware of electrical and mechanical risks before work. Before starting work, he or she should take possible measures to prevent occurrence of such risks. Be sure to contact your nearest TOA dealer if you need to confirm unclear points about risk sources of this unit.

Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

WARNING
Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

When Installing the Unit

• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.
• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified may result in fire or electric shock.
• Since the unit is designed for indoor use, do not install it outdoors. If installed outdoors, the aging of parts causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of electric shock.

When the Unit is in Use

• Should the following irregularity be found during use, immediately switch off the power, disconnect the power supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the unit in this condition as this may cause fire or electric shock.
  • If you detect smoke or a strange smell coming from the unit
  • If water or any metallic object gets into the unit
  • If the unit falls, or the unit case breaks
  • If it is malfunctioning (no tone sounds)
• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage components inside the unit. Refer all servicing to qualified service personnel.
• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they accidentally spill into the unit, this may cause a fire or electric shock.
• Do not insert nor drop metallic objects or flammable materials in the ventilation slots of the unit’s cover, as this may result in fire or electric shock.
• When replacing the fuse, be sure to use the supplied one. Using any other fuse than supplied may cause fire or electric shock.
• Be sure to switch off the amplifier’s power when replacing the fuse.
  Inserting or removing the fuse with the amplifier’s power on may cause personal injury.

CAUTION
Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

When Installing the Unit

• Do not block the ventilation slots in the unit’s cover. Doing so may cause heat to build up inside the unit and result in fire.
• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.
• Note correct polarity (positive and negative orientation) when connecting the power supply cord. Reversed polarity connections will cause damage to the unit.
• To avoid electric shocks, be sure to switch off the power when connecting the unit.
• The VX-3000IM-EB is designed exclusively to be mounted in an equipment rack. Be sure observe the following instructions when rack-mounting the unit. Failure to do so may cause a fire or personal injury.
  • Install the equipment rack on a stable, hard floor. Fix it with anchor bolts or take other arrangements to prevent it from falling down.
  • The supplied rack-mounting screws can be used for the TOA equipment rack only. Do not use them for other racks.

Warning: This equipment is compliant with Class A of CISPR 32. In a residential environment this equipment may cause radio interference.

GENERAL DESCRIPTION

The isolator manager VX-3000IM-EB is designed to control the transmission path of 8 loudspeaker loops equipped with the isolators VM-300IS-EB. Normally (when no fault is present) it sends the audio signal into beginning of the loop.
In case of a short circuit on the loudspeaker line, the isolators isolate the defective line from the proper line. This causes a break of the loudspeaker line. The isolator manager VX-3000IM-EB detects a break of the loudspeaker line and then sends the audio signal into the beginning and end of the loop. It indicates the defective line by an LED on the front panel and provides a control output signal for each faulty line to the VX-3000F.

NOMENCLATURE

Front panel

• Green: channel is OK
• Yellow: failure on the channel

Rear panel

INSTALLATION

The unit with a height of 2 U is designed to be mounted into standard 19” cabinet racks. We strongly recommend using supporting brackets for the unit due to its weight.
Fix the unit by four screws at its mounting holes (see front panel above).

CONNECTIONS

The unit connects the VX-3000F speaker output signals with the speaker line loops. Each speaker line loop can handle up to 150 watts speaker power. When an amplifier output exceeds 150 watts, then two or three loops are to be used.

• Loudspeaker Line Connections
• Connection between a single amplifier output and a single loop

Connection between a single amplifier output and a several loops
Since the maximum wattage per loop is limited to 150 watts, in case of connecting an amplifier with more than 150 watts output power, the loudspeaker lines are to be split into several loops that can handle the total power.
The following drawing shows how to connect several loudspeaker line loops to one amplifier.
Connection diagram with three loudspeaker loops at one amplifier (max. 450 watts):

Connection of the Fault Outputs to the VX-3000F
This connection is quite simple: connect the fault output (RJ45 jack) with the control inputs CONTROL IN 1 or CONTROL IN 2 jacks that shall receive the failure information from the VX-3000IM-EB.with a shielded patch cable (Cat5 FTP/STP or higher with RJ45 plugs).
Example: Connection from VX-3000IM-EB to a VX-3004F, CONTROL IN 1:

Settings in the VX-3000 Setting Software

Relation between Control Inputs and Failure Outputs
Depending on the control input jack used, there is the following relation between the channels of the fault output and the control input jacks CONTROL IN 1 and CONTROL IN 2:

Software Settings
The fault information of the VX-3000IM-EB is to be treated as a failure of the control inputs. All of them are to be implemented into the general fault pattern that you must create for compliance with EN 54-16.
In the following description, we explain the settings by an example with a VX- 3016F and two VX-3000IM-EB. All 16 audio output channels are used. The fault output of the first VX-3000IM-EB (IM1) is connected to CONTROL IN 1, that of the second VX-3000IM-EB is connected to CONTROL IN 2. The settings for other frames are to be made accordingly.

Basic Settings
Set “used” for the “Setting for fault detection functions”.

Surveillance Settings
Since we use the surveillance of the control inputs connected to the VX- 3000IM-EB, make a check for all control inputs that receive a failure information from the VX-3000IM_EB.

The loop isolator detects short circuits and breaks of the speaker lines but not an earth leakage, therefore set the earth lakage surveillance of the speaker lines used.

General Failure: Pattern Settings in Tab “Failure”
For indicating failures of the speaker lines by the general failure, select all control inputs that receive the failure information of the VX-3000IM-EB. In the box “Speaker line fault”, at “Type”, select “Earth only”. (Example: red frames).
