Speaker Connection
T66 speakers have a set of speaker-level 5-way binding posts and, in addition, each speaker has a line-level LFE
(Low-Frequency Effects) input. The LFE input can be used with AV Receivers and Processors to separately feed the
discrete LFE channel (the ".1" signal in a 5.1- or 7.1-channel surround system) into each T66's subwoofer. Unlike a
conventional system in which the powered subwoofer is driven only by a discrete LFE or subwoofer signal, the T66
speakers' powered subwoofer is also driven by low frequencies from the speaker-level inputs from left/right chan-
nels. Using the LFE input with this connection method allows independent adjustment of the LFE channel volume
level for movie playback (or any source with a ".1" channel) from an AV receiver/processor.
If the T66 speakers are main left/right speakers, connect the left main/front channel red(+) terminal of the receiver
or amplifier to the red(+) terminal of the left loudspeaker and the left main/front channel black(-) terminal of the
receiver or amplifier to the black(-) terminal of the left loudspeaker. Connect the right channel main/front channel
red(+) terminal of the amplifier or receiver to the red(+) terminal of the right loudspeaker and the black(-) terminal
of the right main/front channel of the receiver or amplifier to the black(-) terminal of the right loudspeaker. It is es-
sential that both speakers be connected in the same way ("in phase") to its own channel of the amplifier. If a great
lack of bass is experienced, it is likely that one speaker is out of phase (+ and – reversed) with the other.
If using the T66 speaker as surround speakers, connect the left surround red(+) terminal of the receiver or amplifier
to the red(+) terminal of the left surround speaker and the left surround black(-) terminal of the receiver or ampli-
fier to the black(-) terminal of the left surround speaker. Connect the right surround red(+) terminal of the amplifier
or receiver to the red(+) terminal of the right surround loudspeaker and the black(-) terminal of the right surround
channel of the receiver or amplifier to the black(-) terminal of the right surround loudspeaker. Again, it is essential
that both speakers be connected in the same way ("in phase") to its own channel of the amplifier.
Connecting Speaker Cables Only
Illustration 1 shows the simplest setup, which is to connect the T66s
with a pair of Full-Range, equal-length speaker cables. T66s are bi-wire
capable, and ship with special "jumpers" joining the TREBLE or FULL
RANGE and BASS inputs that must remain place in this configuration.
These short jumpers should remain in place even if connecting bare
wire or spades to the speaker-level inputs. But if they fall out contact
your dealer, or simply replace them by running them through the hole
in the center of the binding posts and curling them around the posts
to secure them in place while connecting speaker cables.
If using an AV receiver or processor, simply set the receiver or processor's
speaker setup menu to indicate "Large" for left and right main speakers and
"No" for subwoofer (note that some receivers/processor setup menus
might use "Full-Band" or "Full-Range" instead of "Large."). The bass
management system will then send all low frequencies (including the
LFE ".1" channel) into the left and right channels and it will be
reproduced by the subwoofers in your T66s, giving you all the benefits
of their two built-in subwoofers. (The speakers have a special circuit
that takes the signal from the speaker level input and converts it to
a low-level signal which then drives the subwoofer power amp.)
Illustration 2 is for connecting two discrete equal-length speaker cables
to each speaker in a bi-wire configuration(follow same bass management instructions as above on your AV receiver or
processor). This requires the removal of the two bi-wire jumpers referenced above. Simply open the positive and nega-
tive speaker-level inputs and remove the jumpers. Please store for future use if needed again.
Whenever possible, this is the preferred connection from your AV receiver or power amplifier(s) to your T66. When
bi-wiring, the current modulation of delicate high-frequency audio signals is virtually eliminated from the isolated
midrange/treble cable. This and other audio distortions can be greatly minimized when using a bi-wire speaker
connection with your T66.
