Frequently Asked Questions - Speaker Box 15 DS2 PRO-JECT

How to connect the Speaker Box 15 DS2 speakers to an amplifier?

Make sure the amplifier is off. Connect the red terminal of the speaker to the red terminal of the amplifier, and the black terminal to the black terminal. Repeat for the other channel. Only connect one speaker per terminal.

What is the ideal distance from the walls?

Place the speakers at least 50 cm from the rear wall and 1 m from the side walls. A spacing of at least 2 m between the two speakers is recommended.

Can I use a low-power amplifier?

Yes, but avoid turning the volume up all the way, as this may damage the speakers. Prefer an amplifier with suitable power (4-8 Ohms) and good quality.

How to clean the speakers?

The manual does not specify a cleaning method. Use a soft, dry cloth to dust. Avoid liquid or abrasive products.

What to do if a speaker stops working?

Contact your dealer or Pro-Ject after-sales service. The speakers require no regular inspection, but in case of problems, only a professional should intervene.

What type of amplifier is compatible?

Any good quality amplifier with an output impedance of 4 to 8 Ohms is suitable. Make sure the amplifier power is neither too low nor excessive.

How to achieve good stereo effect?

Place the speakers 2-4 m apart, and the listening position should be at least as far as the spacing between the speakers. Test different locations to optimize the sound.

Are the speakers delivered with cables?

The manual does not mention any supplied cables. You will likely need to purchase suitable speaker cables separately.

Can I place the speakers on a shelf?

Yes, but follow the recommended distances from walls. Avoid placing them in corners or too close to obstacles to preserve sound quality.

How to contact Pro-Ject after-sales service?

In case of problems, first contact your dealer. If necessary, they will direct you to the official Pro-Ject after-sales service.

USER MANUAL Speaker Box 15 DS2 PRO-JECT

You have just purchased one of the best domestic hi-fi loudspeakers available and we hope you will enjoy the music they reproduce for many years to come. Before connecting your loudspeakers and to achieve maximum performance and reliability you should study these instructions for use carefully.

Safety instructions

Avoid spilling liquids on speaker, connection terminal or speaker cable. Never place any item containing liquid such as a flower vase on or near the device. Never place any naked flame sources, such as lighted candles on or near the speakers. The product shall not be used in damp or wet locations, next to a bathtub, sink, swimming pool or any other similar conditions.

Unpacking

Both loudspeakers are packed in one cardboard box and contains all necessary parts:

2 Speaker box 15DS2 floorstanding speaker

8 Spike feet with counter spike discs

Step 1: Place Speaker Box 15DS2 upside down (ideally on a carpet, not to scratch top surface).

Step 2: Mount all 4 spike feet

Step 3: Place Speaker Box 15DS2 with spikes onto the floor (spike discs can be added to avoid scratches on the floor)

Loudspeaker positioning

Ideally both loudspeakers should be positioned at the same level (tweeter in about ear level) and in the same distance from the listener, at least 50~cm from a rear wall, 1 meter from a side wall and ideally forming an equilateral triangle – see page 3 of this manual. If loudspeakers are placed too close to each other or too far apart, stereo images will not be fully developed. The listeners distance from the loudspeakers should be at least equal to and preferably greater than the distance between the loudspeakers. Tests should be made with both speech recordings and music before deciding upon final locations.

Amplifier capacity - power handling

Your loudspeaker system will operate satisfactorily with any good amplifier designed for use with an 4-8 Ohm impedance load. Although loudspeakers are designed to handle high power loadings, you must remember that any loudspeaker that is abused with excessive use of volume, tone controls and graphic equalizers is likely to cause damage to the drive-units. Be careful especially with small amplifiers constantly driven on high power levels, as these may be liable to go into „clipping mode" and distort the signal causing possible damage. If you hear a distorted signal through the loudspeakers you must reduce the power level.

Connecting to your amplifier

We strongly recommend the use of high quality speaker cables, colour coded or grooved cables are recommended to assist checking polarity, your local dealer should be able to advise you on this point. Always switch OFF your amplifier before making any connections or adjustments to the system. Wire the right-hand channel cable so that the positive (RED) terminal of your loudspeaker is connected to the positive (RED) on your amplifier, and the negative (BLACK) terminal of your loudspeaker is connected to the negative (BLACK) terminal on your amplifier. Repeat the instructions for the left-hand channel. Do NOT connect more than one loudspeaker to one terminal on your amplifier.

Please set the volume level to minimum before switching on the amplifier!

Phasing

Providing that you have followed the connecting instruction correctly the loudspeakers should be in phase and provide solid stereo images. If however, you have any doubt as to the phasing of the loudspeakers, try reversing the connections (RED & BLACK) to ONE of the loudspeakers, and play a recording which has plenty of deep bass operating both loudspeakers simultaneously with the stereo amplifier switched to „mono". The correct polarity is indicated by firm full bass, when incorrect, the bass will be noticeably much weaker.

Service

No routine attention is required to the working parts of the loudspeakers and being very reliable loudspeakers rarely require service. Any service problems should in the first instance be referred to your dealer.
