2 Getting Started

We recommend that you:

•Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

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) 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 SPK-OCA504 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-OCA504 - Overview 3

3 Overview

The SPK-OCA504 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-OCA504 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-OCA504 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.

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
