2 SPK-W411T - 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 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.

4 SPK-W411T - Overview

3 Overview

The SPK-W411T includes a pair of high performance indoor on-wall speakers that

can be mounted on the wall vertically or horizontally. The mounting brackets are

made of painted steel that can be attached to each speaker, letting you rotate

each speaker to the left or right. The SPK-W411T 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.

4 Installing the SPK-W411T

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 SPK-W411T (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

The distance should measure up to about 4 meters (13 feet)

2. Strip the ends of the wires to expose a length of approximately 3/8 inch.

3. Pass the speaker wires through the round hole in the mounting bracket (see

Section 4.3

4. Adjust each speaker to the appropriate tap setting (see

Figure 2).

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 2: Adjust Tap Selector

5. Connect one of the + and – terminal block pairs on the rear panel (see

Figure 1) by connecting the:

Wire from the negative terminal on the receiver into the negative

terminal block of the speaker

Wire from the positive terminal on the receiver into the positive terminal

block of the speaker

6. Repeat step 5 for the other speaker (see Figure 7).

7. If required, connect the + and - terminal blocks to the + and - terminal blocks

to an adjacent speaker (as illustrated in the example in Figure 6).

4.3 Installing the Mounting Bracket

To install the mounting brackets, do the following:

1. Mark the location of the mounting holes on the wall.

2. Screw the mounting screws onto the wall at the location that you want to

mount the speakers.

If the location is backed by wall studs, you can use the wood screws

provided. If the location is backed by a gypsum board, use wall anchors (not

included in the package).
