Bi-wiring Bi-amping
CABLES
The connection to your amplifier is extremely important for your sound experience. Therefore, we
recommend using high quality loudspeaker cables from DALI.
Regardless of whether you use your loudspeakers single-wired, bi-wired or bi-amped, please use
the same length and type of loudspeaker cable for left and right loudspeakers.
For the perfect sound experience (both stereo and surround sound systems), the right speaker
must be connected to the output terminals marked "R" or "Right" on your amplifier and the left
speaker to the terminals marked "L" or "Left".
A detail that is often overlooked is connection in correct phase, i.e. the red terminal (+) on the
amplifier must be connected to the red terminal (+) on the speaker, and the black terminal (-) on
the amplifier should be connected to the black terminal (-) on the speaker.
If just one speaker in a stereo or surround sound system is connected out of phase, the bass will
be weak and the overall sound will be diffuse.
CONNECTION OF HELICON S600/S600MK2
There is a built-in crossover and power amplifier in the subwoofer. The subwoofer has a separate
input, if you wish to bypass the crossover, for instance when using a surround processor with
built-in crossover.
The subwoofer has a built-in highpass filter and separate connectors for access to a high-pass
filtered signal.
We recommend using high quality interconnect cables between your amplifier and subwoofer.
Connecting to a Stereo Signal with Full Frequency Range
When connecting the subwoofer directly to a preamp without built-in crossover network of high
quality, we recommend that you connect the subwoofer inputs “LINE IN - LEFT/RIGHT” to a full-range
signal from a normal preamplifier output. This way, the subwoofer’s built-in crossover network filters
the signal so that the subwoofer exclusively reproduces the lowest frequencies.
When the subwoofer inputs “LINE IN - LEFT/RIGHT” are
fed a full-frequency stereo signal, it is possible to take
a highpass filtered signal from the “LINE OUT - LEFT/
RIGHT” sockets. This means that the low frequencies,
which will be handled by the subwoofer, have been
filtered out. The highpass filtered signal is then fed to
the power amplifier that drives the main speakers. As a
result, these speakers no longer have to handle the de
-
manding low frequencies, which in turn means enhanced
clarity from the main speakers.
Connecting to a Mono Signal with Full Frequency
Range
When connecting the subwoofer to just one channel, for
instance when using two units in a stereo set-up, and if
you still want to utilize the built-in crossover network of
the subwoofer to divide the signal as described in the sec
-
tion concerning connection to a stereo signal, the sub
-
woofer input “LINE IN - LEFT” should be used. As with the
stereo connection, the built-in crossover networks of the
subwoofer split the audio signal, resulting in the subwoof
