BETRIEBSANLEITUNG
INTRODUCTION
Excellence is an exclusive quality. It's so easy to recognize, yet so
di๎cult to attain.
JBL craftsmen have been involved in the art of sound for more than
a generation โ€“ signal and source, wood and fabric, transducers and
acoustics โ€“ all of it.
Today these craftsmen continue to perform to the most rigid
standards any craftsmen can submit to: those imposed upon
themselves.
JBL loudspeakers are carefully engineered instruments, pains-
takingly crafted and assembled to watchmaker standards. JBL
enclosures express the excitement of creative design; they are ele-
gant, rigid and ๎‹Šawlessly ๎‹‰nished. JBL transducers and electronics
o๎€er what has been characterized by devoted music listeners as
โ€œthe incomparable JBL soundโ€.
JBL Ti Series loudspeakers are the ultimate expression of over 50
years experience creating loudspeakers that are the ๎‹‰rst choice of
professionals worldwide. This experience, teamed with an extensive
development program of comparisons, experiments, testing and
listening, has resulted in loudspeaker systems displaying truly
exceptional performance.
By following the few simple suggestions contained in this booklet,
you can look forward to superb high ๎‹‰delity reproduction that will
retain its clarity and realism year after year.
UNPACKING
The packing material of your Ti speakers has been designed to
protect the loudspeakers from any damage due to rough handling
during shipment. We strongly suggest that you keep the packing
material for future purposes, in case you are moving or your
loudspeakers should require service.
PLACEMENT
The listening room and the location of the loudspeakers within the
room a๎€ects bass level and bass response, imaging, clarity and
overall quality of sound. No other single factor has the same level of
e๎€ect on the ๎‹‰nal sound quality. The acoustics of the listening room
are determined by the dimensions of the room, its construction and
the furnishings it contains. Rooms that have di๎€erent dimensions
for ceiling height, length and width will give a more even, balanced
sound than rooms where the dimensions are equal to each other,
especially at low frequencies. This is important, especially at low
frequencies, as the room dimensions determine the pattern of
standing waves within the room.
The construction of the room, wooden ๎‹Šoors, wood wall panelling,
plasterboard or brick will a๎€ect the reproduction of low frequencies,
with โ€œsoftโ€ walls, ๎‹Šoors and ceilings resulting in a loss of bass energy
in the room, because the low frequencies are โ€œleakedโ€ out. On the
other hand solid walls, ๎‹Šoors and ceilings like brick and concrete
may cause problems by increasing the level of reverberation time at
low frequencies giving a boomy, fat sound.
At middle and high frequencies furniture, carpets and curtains all
have a damping e๎€ect that might be desirable, depending on the
actual acoustics and your listening preferences.
Ideally, there should be a reasonable balance between the
absorptive material and sound re๎‹Šecting surfaces. If there are two
large re๎‹Šecting surfaces facing each other, the โ€œbounceโ€ between
them will make sounds run together and the music will lack
de๎‹‰nition. Large ๎‹Šat surfaces should be broken up with bookshelves,
drapes, screens or tapestries.
Consult your JBL Ti Series dealer for further information regarding
the use of products or materials designed to control certain acoustic
problems caused by room size, shape or construction. In many
cases, signi๎‹‰cant improvement in performance can be achieved by
careful attention to room acoustics.
Your JBL Ti speakers are able to give a very satisfying sound in a
great variety of listening rooms when set up in an even sided
triangle with respect to the listener. However, a careful setup
procedure will always be rewarding, and for best results we
recommend placement well away from the boundaries of the room
with preferably minimum 0.75 m (30 in) distance to the wall behind
the speakers, and 0.75-1 m (30-40 in) distance to the side walls.
A good guideline is to start by concentrating on the tonal balance of
the sound, aiming for the most neutral reproduction. When the
desired tonal character is achieved, e๎€orts should be directed
towards the recreation of the sound stage โ€“ the imaging.
The tonal balance is roughly determined by the distances to the
walls of the room in combination witht the speci๎‹‰c acoustic proper-
ties of the room. Placement close to walls gives a reinforcement of
lower frequencies compared to placement well away from room
boundaries. Movements of the loudspeaker to give good tonal
balance requires relatively large movements, typically 0.20-0.30 m
(8-12 in).
When a satisfying balance is found, a proper sound stage and stereo
localization is developed by smaller movements of the loudspeaker
in combination with angling towards the listening position.
The Ti speakers are supplied in mirror imaged pairs that will help
build an impressive sound stage due to their asymmetrical shape.
The Ti speakers do not come as speci๎‹‰c left or right enclosures. We
strongly recommend experimentation in order to ๎‹‰nd the most
satisfying overall sound. Attention to every detail of the setup will be
bene๎‹‰cial in terms of improved sound quality.
The JBL Ti 2K should be placed on a rigid and open, preferably
heavy stand of approximately 40-60 cm (16-24 in) height. A
dedicated stand for the Ti 2K is available from your JBL Ti Series
dealer. The JBL Ti 6K and Ti 10K have provisions for the mounting of
spikes at the bottom of the speakers. The spikes can be mounted in
threaded inserts located beneath the rubber feet at the bottom of
the speakers. The bene๎‹‰t of spikes will very often be a more
accurate, tight and dynamic bass reproduction, and a more stable
and precise stereo image. The reason behind this is that the spikes
provide a tighter mechanical coupling between the loudspeaker
enclosure and the ๎‹Šoor, whether hardwood, concrete or brick.
Your authorized JBL dealer will be happy to help you obtain the best
possible performance from your JBL speakers.
INSTRUCTION MANUAL
NOTE: New loudspeakers require a certain amount of โ€œexerciseโ€
before they perform their best. A steady level of performance is
achieved after 8-12 hours of operation, depending on the nature of
the music and the level. Should you want to speed up this process
you can use inter-station FM noise as a signal during periods, where
you would normally not be listening to the speaker. Alternatively a
CD player on "Repeat" would be an appropriate signal source.
CONNECTIONS
IMPORTANT: When connecting or disconnecting loudspeakers from
an ampli๎‹ˆer, the ampli๎‹ˆer must be turned o๎€. Making connections
while the ampli๎‹ˆer is operating could seriously damage the loud-
speaker system and void the warranty. The ampli๎‹ˆer must also be
turned o๎€ before connecting or disconnecting cables at the
ampli๎‹ˆer or pre-ampli๎‹ˆer inputs.
1 mm
2
(18 AWG) insulated wire is the minimum size recommended
for loudspeaker connections up to 5 meters (16 ft). Beyond this
distance, heavier gauge wire is recommended: 1.5 mm
2
(16 AWG)
up to 10 meter (30 ft) and 2 mm
2
(14 AWG) up to 20 meters (60 ft).
These recommendation are given as MINIMUM requirements, and
generally speaking, the speaker leads should be as short as
possible.
Speaker wire and interconnect cables are important components in
an audio system. With all other factors at an appropriate level of
quality the speaker cable and the interconnect cable can make
signi๎‹ˆcant contributions to the perceived sound quality. Careful
selection of cable and interconnect can add or subtract marked
shadings in tonal character. Likewise, di๎€erent cables can have
quite a dramatic impact on the dynamic contrasts experienced by
listeners.
The same care that was given to the internal system wiring in the
JBL TI speakers should be a๎€orded to the selection and application
of the cable that will connect the various components in your
system. Your JBL Ti Series dealer has the experience and knowledge
to recommend suitable interconnects and speaker wire to best
complement your system.
The length of the speaker wire will depend on the location of the
loudspeakers and the ampli๎‹ˆer. Since the ๎‹ˆnal positioning of the
loudspeaker will be determined by careful listening, you may want
to arrange a temporary wiring layout that will allow the moving of the
loudspeaker to experiment with placement. When the best loud-
speaker position is determined, permanent connections may be
made using the shortest cable runs possible. Both left and right
speaker wires should be the same length. In some systems, the
ampli๎‹ˆer may be located near the loudspeaker system and may be
connected using a short length of speaker wire. Although a relatively
long cable between the preampli๎‹ˆer and main ampli๎‹ˆer is required
by such a hook-up, the bene๎‹ˆt of a short ampli๎‹ˆer-to-loudspeaker
connection will often outweigh the drawbacks.
Connections to the loudspeaker system are made at the terminals
located at the bottom of the enclosure. These terminals permit a
variety of connection methods.
The most straightforward connection is made by directly connecting
clean bare wire. This way the connection is made by stripping
8-10 mm of insulation off the loudspeaker wire and passing the bare
wire through the hole in the binding post. If the wire is too thick to
pass through the hole in the terminal in one single bundle, separate
the copper wire into three equal bundles, then pass the center bundle
through the hole in the terminal. Wrap the remaining bundles around
the binding post and twist the center stands. The knob can now be
tightened securely, and any excess wire that is not in contact with the
binding post surfaces should be trimmed to avoid short circuits.
A very convenient way of connection is the use of 4 mm banana-
type connectors, which are then, in turn, connected to the binding
posts. Bear in mind, however, that the number of contact points
should be kept to a minimum, and at the same time each contact
should be as tight as possible.
For the same reason, we recommend the use of the highest quality
spade connectors, expertly connected to the selected cables.
Spade lugs will together with the custom made binding posts
made for the JBL TI speakers, make the best possible connection
between the speaker wire and the loudspeaker system, minimizing
any contact resistance that might degrade the sound ever so slightly.
Any connection in an audio system should not be considered โ€œgood
foreverโ€. All connections should be inspected and cleaned or
remade periodically. Frequency of maintenance depends on the
materials involved in the connection, atmospheric conditions and
other factors. Consult your dealer for speci๎‹ˆc recommendations.
It is essential that both loudspeakers in a stereo system have the
same polarity with respect to the input signal (are in โ€œphaseโ€). JBL
Ti speakers are designed to produce a positive pulse when a positive
signal is applied to the red input terminal.
If the driver cones of the two loudspeakers do not move in the same
direction for a given voltage at the input terminals, there will be a
lack of stereo de๎‹ˆnition and a loss of deep bass.
We recommend experimenting with the polarity of the speakers,
since recordings, program sources or power ampli๎‹ˆers can invert
the polarity of the signal. The โ€œcorrectโ€ connection is the one that
yields the best audible results. Be sure to reverse both left and right
connections to keep the systems in polarity.
MULTI-WIRING
JBL Ti loudspeakers may also be connected to the power ampli๎‹ˆer
using several lengths of wire. The multi-wire connection method
o๎€ers a number of options and advantages.
Each section of the Ti-loudspeaker systemโ€™s internal frequency
dividing network is electrically separated and equipped with its own
pair of input terminals
This way each individual loudspeaker drive unit (and its associated
network) can be connected independently to the power ampli๎‹ˆer.
The loudspeaker system is shipped from the factory with all the
network sections interconnected by strapping bars, so that the
loudspeaker can be hooked up to the ampli๎‹ˆer by a single run of
cables.
Be removing the bars, connections can be made to the individual
network sections using two or more pair of wires (four or more
conductors) as shown in ๎‹ˆgure 1. The wires used may be of the
same type for both low, middle or high frequency sections. The
advantages are that wire e๎€ects (resistance, inductance, etc.) are
reduced, and intermodulation of low and high frequencies in the
cable is avoided. Specialized wires for low, middle and high
frequencies may yield excellent results in some systems.
In either case, the cable for the low frequencies should be as short
as possible, and the left and right cable for each section must be the
