2.1 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.

3 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.
