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.

SPK-WA511 - Getting Started

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)

2. Connect the audio source (for example, a CD or a DVD player and so on) to

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

Slide the mounting bracket over the mounting screws so that the

mounting bracket is secured to the surface
