Connecting Your loudspeakers
It is critical for proper performance that both speakers (left and
right) be connected in proper phase. Note that one terminal on each
speaker (the +) is colored red and the other (the -) is colored black.
Please make certain that you connect the red (+) terminal on each
speaker to the red ( +) terminal of its channel on your amplifier or
receiver, and the black (-) terminal to the black (-) terminal. It is
essential that both speakers be connected in the same way to the
amplifier (in phase). If you experience a great lack of bass, it is likely
that one speaker is out of phase with the other.
Usually
if
distortion is heard when the speakers are being driven at loud levels, it is
caused by driving (turning up) the amplifier too loud and not driving the speakers
with more power than they can handle. Remember, most amplifiers put out their full
rated power well before the volume control
is
turned all the way up!
If
your speakers
distort when you play them loud, turn down the amplifier or get a bigger one.
"Spiking" Your loudspeakers
An optional "spiking" kit has been provided should you desire to
"spike" your loudspeakers. "Spiking" your loudspeakers will provide
greater stability when placing your loudspeakers on carpeting and will
also, according to many experts, result in an overall improvement in
sonic performance. Care should be taken when using spikes as they
may cause damage to wooden or other floors which are susceptible to
being scratched. Definitive Technology is specifically not responsible
for damage which may result from the use of spikes.
The spike kit contains 4 spikes. To install,unscrew the plastic guides
on the bottoms of the speakers. Then screw the 4 spikes into the T nuts.
Then (preferably with the help of another person) lift the speaker
upright and lower it down to its exact desired position on the floor. You
must lower the speaker to the exact position you want because once the
spikes are in place you cannot move the speakers sideways on the rug
or floor - this may damage the floor or the speakers. Next, adjust the
spikes so the speaker sits solidly (and does not rock).
Please note that you can adjust the feet or spikes to tilt the speakers back (front
to back approximately 1/2" to 1" higher than rear) for even better sound.
