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 - 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).

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.
