2: It is safe to have a speaker with a nominal impedance greater than the amplifiers minimum
output rating. But care must be taken not to use a speaker or speaker combination that is below the
amplifier’s minimum impedance capability. Having said that, most reputable amplifier manufacturers
allow for a small safety margin, for instance it is not likely to cause any problem if you connect an
“AARON” 6 ohm speaker to an 8 ohm rated amplifier output. Should you wish to put two speakers on
each amplifier output, a little more care is required. Below is a list of safe combinations that can be
used with the most high quality, modern amplifiers.

If your combination does not fit any of the above seek advice from the amplifier manufacturer
before turning the system on. Note: a 6 plus 6 ohm connection may be possible but check first as the
amplifier will need to be rated into 2 ohms to make this combination safe.
SURROUND SOUND
SPEAKER PLACEMENT
With an audio visual system, “centre channel” and “surround sound” speakers have to be
placed in certain positions to obtain the best surround sound effect. However the system must also
fit in with your room layout and décor, so more often than not the following recommendations can’t be
followed to the letter. Still, our advice is to stick as close as possible to the guidelines below.
With the combined centre channel and main speakers they will give you the best results if
they are placed equal distance on each side of the TV panel. The audio image will also further im-
prove if they are placed at some distance away from the panel. This is despite the fact that we offer
special covers to match the panel height with the expressed purpose of placing the speakers adja-
cent to the panel. Positioning the speakers directly next to the panel is a lifestyle decision that has
the sole benefit of enhancing your home environment without a huge negative affect on the surround
sound image quality.
Surround sound speakers should be placed one each side of your listening position at ap-
proximately ear height or higher. It is also common to place them behind the listening position each
side of the room at ear height or higher. Both positions will give you excellent results but it is worth-
while to note that the software has been recorded assuming the surround sound will come from the
sides.
