2 SPK-W611 - 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
•Use Kramer high performance high resolution cables
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 (such as the Kramer BC-2S cable)
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

SPK-W611 - Overview 3
3 Overview
The SPK-W611 includes a pair of high performance speakers that can be
mounted on the wall vertically or horizontally. The mounting brackets are made of
hardened steel that can be attached to each speaker, letting you rotate each
speaker to the left or right.
3.1 Defining the SPK-W611
This section defines the SPK-W611:

4 Kramer Logo Gently pull the spring-loaded logo to set it to the
horizontal position if the speakers are mounted
horizontally

4 SPK-W611 - Choosing the Best Location
4 Choosing the Best Location
Before installing the speakers:
•Experiment by placing the speakers in different locations before finally
deciding on the most suitable location.
For achieving the best sound, it is recommended to space them at least 6
feet apart, and aim them towards the listening area
•Be sure that the wall type is appropriate for the mounting brackets, that is,
either solid wood, bricks, concrete, hollow building blocks, gypsum (only if it
is properly prepared) or wood studs
•Check that the mounting location is free of obstructions, such as electrical
piping, heat sources, AC ducts or water lines, and so on
•Hold the speaker in the chosen location to verify that it is not interfered by
obstacles such as adjacent walls, window or door frames, beams, lighting
fixtures and so on
Each bracket is specifically designed to hold the weight of the
speaker.
Do not hang anything from the bracket other than the speaker, and
do not place any item(s) on top of the speaker.

5 Installing the SPK-W611
Before installing the speakers, you can paint them to match the surrounding
furnishings (see Section 5.4). If you choose not to paint the speakers, you can
install them directly.
This section explains how to:
•Prepare for installation (see Section 5.1)
•Install the speaker wires (see Section 5.2)
•Install the mounting brackets (see Section 5.3)
•Paint the speakers, if required (see Section 5.4)
5.1 Preparing for Installation
Before installing the speakers, check that you have all the required tools:
•A Philips-head (#2) screwdriver
•A power drill
•Eye and ear protection and a dust mask
•A 2.5mm (0.1”) wood bit or a 6mm (0.24”) masonry bit
5.2 Installing the Speaker Wires
To install the wires, do the following:
1. Make sure that the amplifier power is OFF.
2. Prepare the wires for the speakers:
Use two stranded speaker wires (it is recommended to use the Kramer
BC-2S cables) of similar length for achieving high quality sound
Measure the length from each speaker to the amplifier, and add some
access wire length to easily remove the speakers from the bracket
without having to disconnect the input wires
3. Prepare the mounting bracket installation (see section 5.3.1).

4. Strip the ends of the wires approximately 1/2 inch.
5. Pass the wires from the location of the amplifier to the speaker location.
If the speaker wires are run inside the wall, pass the wires from the
amplifier into the wall and out the hole in the wall where the speaker
is to be installed.
6. Pass the speaker wires through the round hole in the mounting bracket (see
Figure 2).
Figure 2: Installing the Speaker Wires
7. Connect the left side speaker to the left side channel of the amplifier and the
right side speaker to the right side channel of the amplifier:
Unscrew the negative (black) screw-type connector on the rear panel
of the speaker, insert the wire from the negative terminal on the
amplifier, and retighten.
Take care not to insert the insulated part of the wire into the screw-type
connector
Unscrew the positive (red) screw-type connector on the rear panel of
the speaker, insert the wire from the positive terminal on the amplifier,
and retighten.
Take care not to insert the insulated part of the wire into the screw-type
connector

8. Once the speakers are connected to the amplifier, test the connection:
Set the balance control on the amplifier to normal
Play some music with deep bass passages
Listen if the sound comes from both speakers and check if the bass
sounds full and natural
If not, recheck the connections (+ to + and - to -)
9. Attach the brackets to the speakers (see Section 5.3.2).
5.3 Installing the Mounting Bracket
5.3.1 Installing the Mounting Bracket onto the Wall
To install the bracket onto the wall, do the following:
1. Place the bracket so that the narrow edges of
the keyhole slots face upwards and mark the
location of the two mounting holes (use the
bracket as a template).
2. If you are mounting the speaker on a wall
stud, insert the appropriate size screws
through the wall and into the stud. If you are
mounting it on the wall, use wall anchors.
Leave the screw heads protruding just a bit
so the speaker can hang on them.

5.3.2 Installing the Speakers to the Bracket
To install the speakers to the bracket, do the following:
1. Screw the bracket to the speaker using
the bracket knob (remove the knobs and
then screw them back to the speaker
after placing the bracket).
2. Align the bracket with the attached
speaker to the inserted screws and hang
it, letting the screwhead slip into the
narrow side of the keyhole opening (in
the same way you can also hang the
speakers horizontally).
Check, by gently pulling the speakers,
that the speakers are sitting well on the
mounting screws and tighten them if
required.
Check that the speakers are well aligned
against the wall, and tighten if necessary.
3. Loosen the bracket knobs slightly to set
the speaker in the desired angle and
then retighten.

5.4 Painting the Speakers
To paint the speakers so that they match the surrounding area, you need to
prepare the following:
•A spray can of primer paint
•A spray can of paint
•A paperclip or corkscrew for removing the grille
•Masking tape
•A paint mask (see Figure 3)
Remove the following parts of the speaker:
•The brackets and bracket knobs
•The grille gently, using a bent paper clip
Mask:
•The input port area
•The bracket knob openings and end panels
•The grille area

10 SPK-W611 - Installing the SPK-W611
Prepare the masks by cutting heavy nonporous paper in the shape of the areas
you want to mask. For example, use the grille as a template for the speaker front
panel (see Figure 3).
Figure 3: Preparing the Paint Masks
Use primer paint on the cabinet and bracket knobs. When these are dry you can
apply the paint on these, as well as the bracket and grille.
Painting the grille:
When painting the grille (in two layers), you can either cover the logo on the grille
or paint over it. It is best to spray paint the grille using either a spray can or a spray
gun with a compressor set to the finest spray diameter.
