ON / OFF

A sound system should be switched on sequentially. Switch on the self-powered units last in your sound system (switch on the subwoofer before the mid-high system). Switch on the sound sources such as CD players or turntables, then the mixer, then the processors, and finally the selfpowered unit. If you have several units, it is recommended that you switch them on sequentially one at a time.

Follow the inverse order when switching off, turning self-powered units off before any other element in the sound system.

Disconnect the device by removing the mains connector from the mains socket. The mains connector and mains socket must always be freely accessible and never covered or blocked in any way.

Use a power cable equipped with a Neutrik PowerCon NC3FCA connector.

IMPORTANT: Do not disconnect the unit while in use.

Ensure that the device is disconnected from the mains by observing that the ON LED is turned off. Please note that the ON LED can stay on for several seconds after the mains power has been disconnected.

Overheating

This equipment does not normally overheat during normal conditions of use. When overheating occurs, the unit protects itself. You should then find out why and if necessary contact an authorised dealer for technical assistance.

Equalisation

The unit does not need extreme settings of equalisation to produce quality sound. Avoid high levels of gain on the equalisers. Gain values above +3 dB on a console’s EQ are not recommended.

Overload indicator

This device has an indicator (LIMIT LED) that

lights when the signal is excessive.

The indicator should not be lit continuously. This distorts the signal (quickly fatiguing your ears) and may damage the speakers. Therefore, it is recommended that you never work with this LED on; at most it should blink only occasionally.

Low mains voltage

Therefore the current consumed by a 115V version is double the 230V version to achieve the same acoustic power level.

If mains voltage falls below the shutdown voltage for the unit, it will stop playing. When acceptable levels are regained, the unit will switch back on automatically.

Normally it is enough just to let the unit cool down after you have corrected the problem so that the system functions properly again.

Page 14

Manual del Usuario / DR-500 active / User’s Manual

PROBLEM

No sound from the unit. The SIGNAL LED does not light up.

Full power cannot be obtained. The LIMIT LED never lights up.

Sound is distorted. The LIMIT LED is not on, or only lights up occasionally.

Sound is distorted and very loud and LIMIT LED lights up.

Hum or buzz when a mixer is connected to the unit.

Hum or buzz when using lighting controls in the same building.

The ON LED does not light up when the mains connector is connected and the unit is switched to ON.

CAUSE

1 – The signal source is sending no signal. 2 – Defective cable.

3 - The amplifier has overheated.

The signal source does not have a hot enough output.

The mixer or signal source is distorting.

The system is overloaded and has reached maximum power.

1.– The console probably has unbalanced outputs. You may be using an incorrect un-balanced to balanced cable.

2.– The mixer and the powered speaker are not plugged into the same mains outlet.

3.– The audio signal cable is too long or too close to an AC cable

1.– The audio signal cable is too long or too close to the lighting cable.

2.– On a sound system with threephase AC, the lighting equipment and the UNIT are connected to the same phase.

1.– Bad or loose AC connection to the UNIT or the mains outlet. 2 – Faulty AC cable.

SOLUTION

1 – Check that the mixer or sound source is sending signal to the UNIT. 2 – Check that the cable from the sound source to the UNIT is connected correctly. Replace the cable if defective. 3 - Allow the unit to cool down for some minutes and it will function again. Check the main output level of the mixer or channel gains since the unit will have been functioning with excessive levels.

If using a mixer, use the balanced output if available. Use a professional mixer with a hotter output.

Turn mixer channel gains down. Check that none of your signal sources are distorting.

Turn down the mixer's output.

1.– Read the appendix of this manual to make a correct unbalanced to balanced cable.

2.– Connect the mixer and the unit to the same mains outlet.

3.– Use a cable that is as short as possible and/or move the audio signal cable away from mains cables.

1.– Move the audio signal cable away from lighting cables. Try to find out at what point the noise is leaking into the system.

2.– Connect the sound system to a different phase than the lights. You may need the help of an electrician.

1.– Check your connections.

2.– Check the cables, connectors and AC power with a suitable mains tester.

APPENDIX: Line connections: unbalanced and balanced

There are two basic ways to transport an audio signal with microphone or line level:

Unbalanced line: Utilising a two conductor cable, it transports the signal as the voltage between them. Electromagnetic interference can get added to the signal as undesired noise. Connectors that carry unbalanced signals have two pins, such as RCA (Phono) and ¼” (6.35mm, often referred to as jack) mono. 3 pin connector such as XLR (Cannon) may also carry unbalanced signals if one of the pins is unused.

Balanced line: Utilising a three conductor cable, one of them acts as a shield against electromagnetic noise and is the ground conductor. The other two have the same voltage with respect to the ground conductor but with opposite signs. The noise that cannot be rejected by the shield affects both signal conductors in the same way. At the device’s input the two signals get summed with opposite sign, so that noise is cancelled out while the programme signal doubles in level. Most professional audio devices use balanced inputs and outputs. Connectors that can carry balanced signal have three pins, such as XLR (Cannon) and ¼” (6.35mm) stereo.

The graphs that follow show the recommended connection with different types of connectors to balanced processor or amplifier inputs. The connectors on the left-hand side come from a signal source, and the ones on the right hand side go to the inputs of the processor or amplifier. Note that on the unbalanced connectors on the left-hand side, two terminals are joined inside the connector. If hum occurs with balanced to balanced connections, try disconnecting the sleeve (ground) on the input connector. Note that the illustrations show what should be connected to what, but that pin locations on an actual XLR connector are different. Also, pin 2 hot is assumed on XLR connectors.
