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 (we recommend Kramer high-
performance, high-resolution cables) 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 Speakers 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.

Yarden 4-O - Overview
3 Overview
The Yarden 4-O includes a pair of high performance on-wall speakers that can be
mounted on the wall either vertically or horizontally. The mounting brackets, made
of painted steel, can be attached to each speaker, letting you rotate each speaker
from side to side. The Yarden 4-O speakers feature a multi-tap power transformer
for selecting 8Ω (bypassing the transformer) or 70V/100V power settings that are
suitable for an array installation.

Yarden 4-O - Installing the Yarden 4-O
4 Installing the Yarden 4-O
This section explains how to:
Choose the best location for your speakers (see Section 4.1)
Install the speaker wires (see Section 4.2)
Install the mounting brackets (see Section 4.3)
Setup an array installation (see Section 4.4)
Install the Yarden 4-O (see Section 4.5)
4.1 Choosing the Best Location
Before installing the speakers:
Experiment by placing the speakers in different locations before finally
deciding on the most suitable location
Be sure that the wall type is appropriate for the mounting brackets, that is,
either solid wood, bricks, concrete, hollow building blocks, or wood studs
Check that the mounting location is free of obstructions, such as electrical
piping, AC ducts or water lines, and so on
4.2 Installing the Speaker Wires
To install the speakers, do the following:
1. Prepare the wires for the speakers:
Cut the wires to similar lengths
For achieving high quality sound
Measure the length from each speaker to the receiver, and cut the
wires accordingly, adding some access wire length to let you easily
remove the speakers from the bracket without having to disconnect the
input wires
2. Strip the ends of the wires to expose a length of approximately 3/8 inch.
