Section 4: Connecting Your Speakers
Before making any connections always turn off your amplifier.
Although the binding posts on the back of the speakers accept bare wire, it is recommended that the cable be terminated
with soldered 4mm banana plugs. Even if it seems unnecessary, it is advisable to use equal lengths of speaker cable to
each speaker.
Most speaker cable is marked so that it is possible to distinguish between conductors by the color of the insulation or by a
white stripe or small raised edge along one conductor. Correct phasing of the speakers is vital for sound quality.
Very tight and positive connections are necessary. Care should be taken to ensure that the connections are neat and that
no strands from the two conductors are allowed to touch.
At the rear of each speaker there are two pairs of red and black terminals marked LF and HF. Under normal operating
conditions these pairs are linked across by connecting links (supplied), so that the input to one pair of terminals will be fed
to both.
Your speakers should be wired in phase with each other. Proper phasing will be assured if the speaker cables connect the
red speaker input to the plus (+) or “hot” amplifier output terminals, and the black speaker input terminals to the negative (-
) or “ground” amplifier output terminals (see figure 1).
Should you be interested in absolute phase of your system, a positive voltage at the red terminal of the speaker will cause
all drivers to move outward, provided the links are in place.
The facility to split the crossover on the AN-E range allows the speakers to be operated in a bi-wired or bi-amplifier mode.
The crossovers are split by removing the connecting links between the HF and LF terminals on the rear of the speaker. Bi-
wiring (see figure 2) involves running two sets of cables to the rear of each speaker so that the LF section of the crossover
is fed by one set, and the HF section by the other. Both sets of cable are connected together to the corresponding pair of
terminals on the back of the amplifier. Two preamplifier outputs per channel are required for any of the following bi-amping
set-ups.
Care should be taken when using the loudspeakers with very high-powered amplifiers. Although these speakers are
reasonably tolerant and have high power handling, they are also very efficient and therefore require considerably less
power than many other similar loudspeakers. If audible distortion occurs the amplifier or the loudspeaker is being
overloaded and damage is likely to result.
The following diagrams show how to connect your speakers for different connection scenarios.
