Frequently Asked Questions - DX1500 Malone

How to connect speakers in stereo mode?

Connect each speaker to the corresponding outputs (CH1 or CH2) respecting a minimum impedance of 4 ohms per channel. Use the 6.3 mm jack, NL4, or screw terminal outputs.

How to use the bridged mode?

Set the mode switch to "Bridged". Connect the input signal only to channel CH1. Connect the speaker between the + terminals of CH1 and CH2. Do not use the - terminals in bridged mode. The load impedance must be 8 ohms.

What to do in case of hum or ground loop?

Use the Ground Lift switch located on the back of the amplifier to isolate the chassis ground and eliminate ground loop noise.

What is the required mains voltage?

The amplifier operates at a voltage of 220-240 V~, 50 Hz. Check that your mains socket matches before connecting the device.

Can I use the amplifier outdoors?

No, the device is designed for indoor use only. Protect it from rain, moisture, and splashes. Do not install near water.

How to clean the amplifier?

Disconnect the device from the mains. Use a soft dry cloth to clean the surface. Never use liquid or abrasive products.

Is it normal for the amplifier to get hot?

Yes, some heat is normal during operation. Ensure ventilation grilles are not obstructed and leave at least 5 mm space around the device for proper ventilation.

What to do if the fuse blows?

Replace the fuse with a strictly identical type (see fuse holder on the back). If the problem persists, contact customer service. Do not use a fuse of a different value.

Can I repair the amplifier myself?

No, opening the device exposes you to risk of electric shock and voids the warranty. Entrust any repair to qualified personnel.

How to dispose of the amplifier at end of life?

Do not throw it in household waste. Take it to a collection point for waste electrical and electronic equipment (WEEE) in accordance with local regulations.

SAFETY INSTRUCTIONS

• Children over 8 years as well as mentally, sensory and physically impaired persons may only use the device if they have been informed in detail about the functions and safety precautions by a supervisor responsible for them beforehand and understand the associated risks.
• Observe all the instructions given in the operating instructions.
• The unit must not be used near water or in a humid environment.
• Take care not to spill any liquid over the appliance and the appliance openings.
• Move the unit carefully so as not to damage it.
• Do not block the unit outputs.
• Do not place the unit near heat sources (e.g. heating). Do not expose the device to direct sunlight.
• Plug the power plug of the device into the mains socket.
• Insert the mains plug of the device into the socket in the intended way.
• Under no circumstances should you attempt to service or repair the device yourself. In this case, the warranty becomes void.
• The mains plug is used to disconnect the unit from the mains after it has been switched off. Make sure that the mains plug is always freely accessible.
• Do not expose the appliance to splashing water and do not place objects filled with liquids, such as vases, on the appliance.
• Do not expose the batteries to extreme heat such as sunlight or fire.
• Never obstruct the ventilation of the appliance by blocking the ventilation openings with objects such as newspapers, tablecloths, curtains etc.
• Make sure that a minimum distance of 5 mm is maintained to all sides of the unit.
• Do not place any sources of ignition with an open flame, such as lit candles, on the device.
• Only use the unit in a temperate climate, not in a tropical climate.

WARNING

Danger of injury! To reduce the risk of electric shock, do not open the unit cover or the back of the unit. The unit does not contain any parts that could be serviced by the customer.

Please contact customer service or similarly qualified personnel for maintenance and repair.

DEVICE OVERVIEW

1 6.3 mm jack inputs: Two 6.3 mm jack sockets for connecting a signal source (mixer, etc.). RCA
2 Inputs: Two RCA input sockets for connecting a signal source (mixer etc.)
3 Mode switch: The amplifier can operate in 2 modes: Stereo and Pressed. Select one of these modes: Stereo mode: Standard left/right stereo mode. Bridge mode: This mode of operation combines both channels on one channel, resulting in doubling the power of that channel. Connect the signal to the left input channel and the output level can now be adjusted with the left volume control.
4 Ground Lift Switch: Disconnects the circuits from the ground in case of problems with ground loops.
5 6.3 mm output: In stereo mode, the load impedance is 4 ohms per channel.
6 NL4output: In stereo mode, the load impedance of each channel is 4 ohms. Pin +1 & +2 = + output, Pin -1 & -2 = - output
7 Screw connections Loudspeaker outputs: 4 Ohm per channel. In bridge mode 8 Ohm.
8 Mains input: First plug the IEC plug into the socket on the appliance and then plug the other end into a power socket
9 Fuse holder: The fuse protects the amplifier and the connecting wires against defects. Replace only with a completely identical fuse.

OUTPUT CONNECTION

The amplifier must be switched off while making the connections. The speakers can be connected via the NL4 sockets or via wires to the screw terminals. In the table below, select the appropriate wire gauge that corresponds to the distance between the amplifier and the speaker.

Distance Strength
< 10 m 1.5 mm ^2
> 10 m < 20 m 2.5 mm ^2
> 20 m < 30 m 4.0 mm ^2

LINE-UP

The amplifier can be set to 2 operating modes:

1. Stereo connection

Set the mode switch (3) to stereo. In this mode, the amplifier has two independent channels, each with its own input and volume controls.

2. Bridge operation

Set the mode switch (3) to 'Bridged'. As already described, the output power is doubled. Connect the audio cable to input 1 and the output signal can now be adjusted with the volume control of channel 1. Connect the speakers to the positive (+) outputs of both outputs and not to the (-) output or ground. The negative outputs must NOT be used in bridge mode.

POWER SUPPLY

Before connecting the amplifier to the power supply, make sure that the voltage of the power supply corresponds to the supply voltage of the amplifier. First connect the IEC end to the appliance and then the power cord.

Important instructions

• Make sure that all cables are connected correctly!
- Check whether the speakers are suitable for this amplifier!
- Never cover the ventilation grids!
- Protect from rain and moisture!
