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 cables1
3 Overview
The SPK-OC508 includes a pair of high performance speakers that can be
mounted on the wall vertically or horizontally, and indoors as well as
outdoors2
To achieve the best performance:
. 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.
•Connect only good quality connection cables, thus avoiding
interference, deterioration in signal quality and level, and elevated
noise- levels (often associated with low quality cables)
•Avoid interference from neighboring electrical appliances and position your
Kramer SPK-OC508 away from moisture, excessive sunlight and dust
1 The complete list of Kramer cables is on our Web site at http://www.kramerelectronics.com
2 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

•Install the mounting brackets (see section 5.3)
5.1 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

5.2 Installing the Speaker Wires
To install the speakers, do the following:
1. Prepare the wires for the speakers:
Use the 4 meter 24AWG, black and white dual color wire cut to
similar lengths1
Measure the length to reach from each speaker to the receiver, adding
some access wire length to let you easily remove the speakers from
the bracket without having to disconnect the input wires
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 5.3).
5.3 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 the mounting bracket over the mounting screws so that the
mounting bracket is secured to the surface.
4. Slide a speaker into each mounting bracket.
5. 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.
6. You can slightly loosen the knobs on a speaker to adjust its direction.
