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)
•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.
2.2 Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC
aims to reduce the amount of WEEE sent for disposal to landfill or incineration by
requiring it to be collected and recycled. To comply with the WEEE Directive,
Kramer Electronics has made arrangements with the European Advanced
Recycling Network (EARN) and will cover any costs of treatment, recycling and
recovery of waste Kramer Electronics branded equipment on arrival at the EARN

SPK-W511 - Overview 3
3 Overview
The SPK-W511 includes a pair of high performance speakers that can be
mounted on the wall vertically or horizontally, and indoors as well as outdoors. 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 speakers are weather resistant but not waterproof, and can
withstand the humidity in the air. We recommend that you locate
them in an area that is covered and protected from rain.

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)
•Install the SPK-W511 (see Section 4.4)
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. 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 approximately 3/8 inch.
3. Pass the speaker wires through the round hole in the mounting bracket.
4. Unscrew the negative (black) screw-type connector, insert the wire from the
negative terminal on the receiver, and retighten.
5. Unscrew the positive (red) screw-type connector, insert the wire from the
positive terminal on the receiver, and retighten.

6. Insert the brackets (see Section 4.3)
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 where 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 2).
