Connection Cables
Take care of your cables, always holding them by the connectors and avoiding knots and twists when
coiling them: This gives the advantage of increasing their life and reliability. Periodically check your
cables. A great number of problems (faulty contacts, ground hum, discharges, etc.) are caused entirely
by using unsuitable or faulty cables.
Speakon
Input is a Speakon connector for connecting a speaker-level signal.
Output is a Speakon connector paralleled with the input connector, for daisy-chaining speakers.
Wiring:
Pin 1+ = Signal (+)
Pin 1- = Ground (-)
Maintenance
The Pure-18S requires almost no maintenance. However, you should keep the unit clean. Disconnect the
mains power supply, and then wipe the cover with a damp cloth. Do not immerse in liquid. Do not use
alcohol or solvents.
Keep connections clean. Disconnect electric power, and then wipe the connections with a damp cloth.
Make sure connections are thoroughly dry before linking equipment or supplying electric power.
Troubleshooting
No Sound
Always check if all the cables and cords are connected. Always turn off power to the area before
checking the wires, to prevent electric shock.
If everything works properly and there is still no sound, revisit the manufacturer’s instructions to make sure
they were followed during installation. If everything was installed correctly and there is still no sound, you
may want to consider bringing in a professional to take a look at your speaker.
If the speakers do not operate properly, refer servicing to a technician.
Suspect two potential problem areas as: the power supply and the speakers.
01)
Power supply. Check if the unit is plugged into an appropriate power supply.
02) The speakers. Return the Pure-18S to your DAP Audio dealer.
03) If all appears to be O.K., plug the unit in again.
04) If you are unable to determine the cause of the problem, do not open the Pure-18S, as this may
damage the unit and the warranty will become void.
05) Return the device to your DAP Audio dealer.
Sound Warping
If the sound coming out of your speaker is loud enough, but seems to be warped or distorted, your treble
or bass levels may need to be adjusted.
If there are not many pieces of furniture in the room and the floor has no carpet or rug, then you will most
likely have to set your treble to minus. With very little in the room to absorb the sound, too much treble
can make the sound bounce off of fixtures in the room, making it tinny sounding.
With the bass, if the speaker is too close to a wall and is not aimed properly, then you will need to set the
bass to minus, to stop the low tones from bouncing off of the walls or large pieces of furniture.
