OVATOR S-600 & S-400 – English
4 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.
4.1 Cables and Connectors
If your Ovators are to be used with Naim amplification,
Naim loudspeaker cable will produce the best results and
is necessary with some amplifiers. Cable lengths to both
speakers should be equal and be between 3.5 metres
and 20 metres. If the position of a speaker in relation to
the amplifier results in spare cable do not coil the cable
but lay it out back and forth between the amplifier and
speaker.
The Ovator connection terminals are intended to accept
the custom-designed Ovator speaker connector. This
connector is designed to provide the best possible
performance. Other 4mm plugs can be used however the
results will be unpredictable. Your retailer will be able to
make up speaker cables terminated on one end by the
Ovator connector and on the other end by a connector
appropriate to the driving amplifier.

4.2 Connection Polarity
It is important that Ovators are connected with the correct
polarity. Ensure that the positive terminal on each speaker
(marked
+
) is connected to a positive output terminal on
the amplifier and the negative terminal on each speaker
(marked
–
) is connected to a negative output terminal on
the amplifier. Diagram 4.3 illustrates the Ovator connection
panel.
Note:
Naim speaker cable has a rib running down one
side to aid polarity identification. The positive side of Naim
speaker plugs have a small protrusion for identification.
