CONNECTING THE D-200 & D-400
CENTRE CHANNEL
CENTRE CHANNEL WIRING INSTRUCTIONS
After you have connected the two lower terminals in the normal manner to the main left and right
amplifier outputs wire the centre channel as follows. The centre channel wiring process is the same
for the D-200 and D-400. If you refer to the diagram you will see that a twin cable is connected to the
top terminal of the speakers on both sides. Then at the back of the Amplifier these two cables are
then twisted together and connected to the amplifiers centre channel output. This results in the two
part centre channels being wired in parallel. Please note the combined impedance of the two centre
channel half’s is 6 ohms.
SPEAKER INPUT IMPEDANCE
Very important please note: What we state in this section relates only to the AARON
LOUDSPEAKER product, we are not responsible for any nominal specifications quoted by any
other manufacturers that may be inaccurate.
It is important that you understand a little about your speakers impedance for two main rea-
sons. One is to calculate how much undistorted power your amplifier will deliver. Secondly to check
that the speaker’s impedance is suitable for your amplifier or if it’s safe to have two speakers on the
output of each channel. The speaker input resistance is quoted as the “nominal impedance” this is
what you base all your calculations on.
1: If you wish to calculate the output power from the amplifier then you must first look at the
amplifier specifications. It will usually give you an output rating for 4 ohms and 8 ohms. If the nominal
speaker value is 8 ohms for example, then the amplifier’s power rating for 8 ohms is the one you have
to allow for. Note: If the speaker’s nominal impedance is 6 ohms (which is the case with some models
on the Aaron range) then the maximum undistorted power from the amplifier will be half way between
the 4 ohm and the 8 ohm rating.
These wires can be connected to
the other center channel speaker input
instead of directly to the amplifier.
Note: Wires are
twisted together.
Left and Right Main channel
connections are done to the
lower terminals on the speakers.
