Introduction and Unpacking

The Ovator S-800, S-600 and S-400 are very high performance speakers that will

repay effort spent on installation. It is important that you read this manual before

fully unpacking and installing your Ovators. The manual begins with unpacking

instructions. Ovators are extremely heavy and to minimise the risk of damage

or personal injury you should follow these instructions carefully. Unpacking and

installing Ovators is a two-person task and should not be attempted alone.

4 Installation

Once your Ovators are fully unpacked they may be manoeuvred into their initial working

positions. Take care that the floor-spikes do not cause damage or personal injury. The

S-800 and S-600 incorporate BMR transit screws. These should not be removed until the

speakers are installed in their final positions. The S-400 incorporates no transit screws.

Positioning guidelines are provided in the following paragraphs but you should be

prepared to make positioning adjustments as the speakers “run-in” and as you become

more familiar with them.

Ovator loudspeakers are not magnetically shielded and should be kept well away from

CRT displays and other magnetically sensitive items.

4.1 Positioning

The performance of any loudspeaker will be influenced

by the room and position in which it is located. Even small

changes of loudspeaker position can significantly influence

the sound. Changes of room contents, the introduction of

significant piece of furniture for example, can also have an

effect.

The following paragraphs constitute only a general guide

to Ovator positioning. Every listening room is different and

you may find an alternative positioning solution works best

in yours.

In general, try to choose a site for the speakers where they

are located between 2.0 metres and 4.0 metres apart,

clear of room corners, and where each one is between

0.25 metres and 1.0 metre away from a solid rear wall.

The distance between the speakers and the rear wall is

The Ovator S-800 and S-600 BMR (balanced mode

radiator) modules are fitted with a twin leaf-spring

suspension system. The suspension system is restrained

during shipping by two transit screws that must be released

before use. The transit screws are located on the rear face

of the speaker directly behind the BMR.

Use the supplied 5mm Allen key to unscrew the transit

screws. Remove the screws and store them safely. Diagram

5 Connecting

Ovators incorporate a passive crossover but can be converted for use in active systems

using the appropriate Naim active crossover and multiple amplifiers. Contact your local

retailer or distributor for more information.

to make up speaker cables terminated on one end by the

Ovator connector and on the other end by a connector

It is important that loudspeaker cables are arranged and

dressed so that mechanical stress is minimised and that no

undue force is applied to the connectors either during or

after connection.
