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
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (such as the Kramer BC-2S) 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 Yarden IH-1 away from moisture, excessive sunlight
and dust

This section describes:
The optimal installation recommendations (see Section 5.1)
How to install and mount the speaker (see Section 5.2)
How to set up an array installation (see Section 5.3)
5.1 Installation Recommendations
For optimum installation:
Make sure that there are no objects that may block the area between the
listener and the speakers
Fill the wall cavity behind the speakers with fiberglass insulation or mineral-
wool. Keep the same amount of insulation for each of the speakers to achieve
a true consistent bass response

5.1.2 Setting up a Theater Application
When setting the system in a theater setup (as shown in Figure 3):
Place the main front speakers on each side of the display at a minimal
distance of 5cm from the edge of the display
Center the speakers to the display screen
Locate the center speaker under the display screen
If you want to add additional speakers on the side walls, we recommend that
you place them at the same height of the main front speakers

Do not nail or staple the speaker wires.

5.2 Installing the Speaker
To install the hidden speaker inside the wall:
1. Check that there is no infrastructure or studs behind the wall where you want
to locate your speaker.
2. Place the cut out template on the wall in the correct location.
3. Mark the opening in the correct location by tracing the template.
4. Cut out a hole or small area within the marked template.
Initially, you can cut a smaller area inside the marked hole just to be sure that the area
behind the wall is clear. To do so insert a piece of “L-shaped” wire into the smaller
opening and rotate it. If the wire hits any obstacle which prevents you from installing the
speakers, you will need to move the template and test the area behind the wall again.
5. Cut out the full-sized opening according to the template.
6. Route the wiring from the amplifier to the speakers’ cut out holes, taking care
not to place them next to electrical wires or at least at a distance of about two
feet from an AC line.
7. Adjust each speaker to the appropriate tap setting (see Figure 4).
Set the tap according to the power requirements of the speaker based on its location in the
room (for example, a speaker located in a remote corner may require additional power)
Figure 4: Adjust Tap Selector
8. Connect the + (red) and – (black) wires to the + and – terminal block
connectors of the speaker.

9. Insert the top clamps through the opening, letting the clamps grip the wall
from the inside of the wall and slide the speakers upwards.
10. Insert the lower clamps through the opening and gently slide the speaker
downwards until the lower clamps are locked in place.

5.3 Setting up an Array Installation
When installing the Yarden IH-1 in an array installation layout, you need to define
the distance between speakers according to the uniformity of the coverage desired
and the budget. You can set the power on each speaker to get the desired power
level in different installation areas.
Figure 6 shows an example of parallel wiring in a square array installation:
