Dear JENSEN Customer
Congratulations! Your new JENSEN loudspeaker system is an out-
standing home hi-fi product that will give you many years of reliable
service. The superlative quality of JENSEN products is renowned all
over the world and meet or exceeds all official audio standards.
In order to avoid possible errors or damage please take the time to
study the following Important Information before unpacking and
installing the new speakers.
CONNECTING YOUR JENSEN SPEAKERS
Strip the insulation from the connection cable ends and twist the ends
tightly or tin them with solder. Then insert the ends in the connection
terminals and secure them with the spring mechanism or terminal
screws.
Caution: Take care to ensure that the speaker cables are connected
with the correct polarity!!
Connect the negative amplifier output terminal (black) to the negative
connection terminal of the JENSEN speaker (also black). Proceed in
the same way to connect the positive terminals, which are normally
red. Standard speaker connection cables normally have coloured
marking of identification in the surface of the insulation to distinguish
the two leads from one another.
CHOOSING THE BEST POSITION
FOR YOUR JENSEN SPEAKERS
The optimum listening position is at the tip of the so-called “stereo tri-
angle” (fig. 1 and fig. 1a). The equilibrium between the left and right
stereo channels is best in this position, providing the most balanced
and realistic sound reproduction.
Your JENSEN speakers will operate most efficiently when they are
located in parts of the room with “hard” acoustics, i.e., areas including
hard, smooth surfaces such as walls and wooden furniture. The speak-
ers should radiate the sound from this hard area into the “softer” parts
of the room containing sound-absorbing elements such as upholstered
furniture, carpets and so on.
Make sure that there are no sound-absorbing obstacles between the
speakers and your listening position, as this will muffle the sound and
impair your listening pleasure.
Install the speakers at least one metre away from your television set to
avoid interference to the TV picture by the magnetic fields. Some
other JENSEN speakers are also shielded - please check the operating
instructions and the labels on the back of the speakers before
installing.
If possible, bookshelf speakers should be installed so the tweeters are
on the same level as the listener’s ears. If you install the speakers in a
wall unit, take care to ensure that the fronts of the speakers are flushed
with the front of the wall unit.
ONLY USE TONE CONTROLS WHEN
ABSOLUTELY NECESSARY
You will get the best sound from your speakers when all tone controls
are in the middle position. This neutral settings enables the speakers
to reproduce the music absolutely naturally and without distortion.
JENSEN speakers are designed to produce optimum sound without
any bass or treble modifications.
WARNING: If you turn up the tone controls too far at high volumes
you may actually cause irreparable damage to the tweeters and
woofers!
USE THE VOLUME CONTROL WITH CARE
You can also damage the speakers by using the amplifier whose power
significally exceeds the rated capacity of the speakers. In practice,
however, this kind of damage is actually very rare. Surprisingly, weak
amplifiers connected to speakers with high power rating pose a much
greater risk. In such a configuration it is quite possible to overdrive the
music signal, even at medium volumes. This results in audible and
measureable distortions, which cause excessive mechanical stresses
that will ultimately destroy the speakers. Always remember that the
power rating of your speakers is for clear music signals, not distortion.
It is thus very important to match the output power of your amplifier
to the capacity of your speakers. Always take care to adjust the vol-
