Yarden 8-C - 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 (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.

3 Overview
The Yarden 8-C consists of a pair of high performance closed back speakers.
Mount your Yarden 8-C speakers to the ceiling in one of two ways: either directly
onto the ceiling or, for added protection, secure the speakers safely, using our
ceiling mounting kit that is provided free (see Section 5.3).
The Yarden 8-C 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. Figure 1shows an example of how the Yarden 8-C can be
installed in a boardroom setup:

Each Closed-back Ceiling speaker is supported by a C-ring and two tile rails. The tile
rails prevent the speakers from falling if the tile itself comes out or falls apart, as
their ends catch onto the T-grid. When mounting onto the ceiling tiles, use both
supports. When mounting onto a sheetrock ceiling, the C-ring alone is used to
reinforce the ceiling material.
Be sure that the tiles can support the speaker. Smaller sized tiles or
fiberglass-type tiles cannot support the weight of the speakers.
When this is the case, the speakers will need additional support.

Yarden 8-C - Installing the Yarden 8-C Closed-back Ceiling Speakers
5 Installing the Yarden 8-C Closed-back
Ceiling Speakers
This section explains how to install the Yarden 8-C, that is:
Choosing the best place to locate your speakers (see Section 5.1)
Cutting the ceiling tile (see Section 5.2)
Mounting the speakers (see Section 5.3)
Setting up an array installation (see Section 5.4)
Painting the speakers (see Section 5.5)
5.1 Choosing the Best Location
Ideally, locate the speakers above the main listening area. Before doing so, be
sure that:
The desired location is free of obstructions, such as electrical piping, AC
ducts or water lines, and so on
There is enough space behind the mounting surface for the speakers
The rear side of the speaker is not blocked by wall studs or other objects
5.2 Cutting the Ceiling Tile
To cut the ceiling tile, do the following:
1. Remove the circle in the supplied template.
Keep this template for later use as a mask, as you may want to paint the speakers (see
Section 5.5)
2. Mark the opening in the correct location by tracing the hole in the template.
3. Cut out the hole according to the template or with a circular cutter set to the
appropriate cutout size.
Initially, you can cut a smaller area inside the marked hole just to be sure that the
space above the speakers is clear
