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-W511T - Overview
3 Overview
The SPK-W511T 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-W511T 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.

7 Tap Selector Adjust each speaker to the appropriate tap setting:
For 70V, 1.2W, 2.5W or 5W; for 100V, select 2.5W, 5W or
10W or select 8Ω(to bypass the transformer when
connecting directly to an amplifier without using the 70/100V
array option), see

4 Installing the SPK-W511T
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-W511T (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
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
of 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).
3. Slide a speaker into each mounting bracket.
4. Align the bracket screw holes (upper and lower) to those on the speaker and
screw a knob to each of the holes to secure the speaker to the bracket (see
Figure 3).
Figure 3: SPK-W511T with Brackets Connected
5. Slide the mounting bracket over the mounting screws so that the mounting
bracket is secured to the surface.
6. You can slightly loosen the knobs on a speaker to adjust its direction.

4.4 Setting up an Array Installation
When installing the SPK-W511T in an array installation layout, you have to define
the distance between speakers as well as the layout pattern (square or
hexagonal). The distance between speakers is set according to the uniformity of
the coverage desired and the budget.
The coverage angle of the speaker determines the coverage area and the number
of speakers required in the array installation. Two patterns are usually used for
array installations, square (see Figure 4) or hexagonal (see Figure 5), depending
on the shape of the installation area. The speakers are positioned according to
their coverage area.
Figure 4: Square Layout
Figure 5: Hexagonal Layout
You can set the power on each speaker to get the desired power level in different
installation areas.
