Dolev 8 - Getting Started

2 Getting Started

We recommend that you:

Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

Review the contents of this user manual

Go to http://www.kramerelectronics.com/support/product_downloads.asp

to check for up-to-date user manuals, application programs, and to check if

firmware upgrades are available (where appropriate).

2.1 Achieving the Best Performance

To achieve the best performance:

Use only good quality connection cables (such as the Kramer

C-XLQM/XLQF) to avoid interference, deterioration in signal quality due to

poor matching, and elevated noise levels (often associated with low quality

cables)

Do not secure the cables in tight bundles or roll the slack into tight coils

Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

Position your Kramer Dolev 8 away from moisture, excessive sunlight and

dust

This equipment is to be used only inside a building. It may only be

connected to other equipment that is installed inside a building.

Do not open the housing of the speaker; doing so may reduce the

quality of the sound.

Dolev 8 - Overview

Dolev 8 - Installing the Speaker

5 Installing the Speaker

This section explains how to:

Choose the best location for your speakers (see Section 5.1)

Setup mid/near-field (see Section 5.2) or far-field (see Section 5.3) Installation

Install the speaker (see Section 5.4)

5.1 Choosing the Best Location

For optimum installation:

Speakers should be positioned at least 50cm from the walls

Install the Dolev 8 so that the center point between the tweeter and the

woofer are at ear level. If required, use a speaker stand

If required, use sound absorbing materials around the room

Place the speaker facing towards the listener to minimize the distance and

reflections from the walls and get the best stereo image

5.2 Setting up Mid/Near-Field Installation

Mid-field or near-field installation is usually directed towards a specific listener or

listeners in a specific location of the room. To maximize your listening experience:

1. Make sure that the speakers are set at head height (whether you will be using

the speakers sitting down or standing up).

Figure 2: setting the Dolev 8 at head height

Dolev 8 - Installing the Speaker

2. Position the speaker at an angle so that together with the listener, an

equilateral triangle is created.

3. Try to keep the speakers at a distance of about 50cm from the walls

4. Try to keep a distance of about 1.5 to 2 meters between the speakers.

Figure 3: Dolev 8 Optimum positioning

Note that even though the illustration in Figure 3 shows two

speakers each Dolev 8 package includes one speaker.

5.3 Setting up Far-Field Installation

Far-field positioning is suitable for a large amount of listeners (unlike the near-field

positioning where the speakers are directed at a specific listener). To maximize the

listening experience:

1. Make sure that the speakers are facing the center of the room.

2. Make sure that both speakers are placed along the same wall in the room

(not facing each other).

3. Aim to achieve the largest sweet spot.

For optimum results we recommend that you either experiment and locate the

sweet spot by trial-and-error or alternatively, consult an acoustic engineer.
