Achieving the Best Performance  
To achieve the best performance:  
Use only good quality connection cables (such as the Kramer BC-2S) 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 SPK-WA511 away from moisture, excessive sunlight  
and dust  
To ensure that you obtain the best sound results, do not open the  
housing of the passive speaker or the active speaker.

Overview  
The SPK-WA511 is a powered two-way speaker system designed for indoor wall  
mounting. The system accepts a line level stereo input and amplifies it using a  
built-in amplifier and outputs a speaker signal to the passive speaker.  
The SPK-WA511 speaker system features:  
Three available inputs (that can either be connected separately or  
connected simultaneously to form a mix of the inputs) that consist of:  
.
A Line level unbalanced stereo audio input on a 3.5mm mini jack  
connector  
.
.
A balanced stereo audio input on a 5-pin terminal block connector  
An unbalanced stereo audio input on two RCA connectors  
An output to external amplified or non-amplified speakers  
An output to an external sub-woofer  
A unique looping output, letting you chain additional pairs of active and  
passive speakers  
TREBLE, BASS and VOLUME control knobs  
A control panel on the back of the active speaker that controls all the  
functions of both speakers  
A magnetic shield  
Enhanced bass reflex design  
An integrated 2x30W stereo amplifier (no external amplifier required)  
A self adjusting power range of 90 to 240V AC  
Auto-power shutoff  
The SPK-WA511 is enclosed in an ABS cabinet and can be mounted indoors on  
the wall, vertically or horizontally. The mounting brackets are made of hardened  
steel that attach to each speaker, letting you rotate each speaker to the left or  
right.

Installing the Speakers  
This section explains how to:  
Choose the best location for your speakers (see Section 5.1)  
Install the speaker wires (see Section 5.2)  
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.  
You cannot mount the brackets on gypsum walls  
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. Connect the + and - stereo sockets of the active speaker to the + and -  
stereo sockets of the passive speaker using the cable supplied, as follows:  
Passive Speaker (R)  
Active Speaker (L)

one of the INPUT connectors on the active speaker.  
3. Connect the power.  
4. Adjust the volume on the input source.  
5. Adjust the volume control on the rear side control panel.  
6. Adjust the bass and treble control on the rear side control panel.  
7. If required, connect an additional set of speakers by connecting the LOOP  
OUTPUT connector to the input of a second active speaker.  
8. If required, mount the speaker on the wall via the removable mounting  
brackets. To do so:  
.
.
Mark the location of the mounting holes  
Screw the mounting screws (not included in the package) into the  
mounting holes  
.
