Ideally you want to play one of your most favourite pieces of music through the system that has rich
sounds and plenty of bass, being something you can identify with later when testing the helmet
installation.
Please check to ensure that both rider and passenger master volume controls are still set per picture C
on page 6.
WARNING; because the system is capable of being VERY LOUD for use with earplugs CAUTION should
be used when turning the volume control clockwise above the mid-way position unless you are using
conventional earplugs.
Plug the 3 pole end of the stereo music lead (supplied in the kit) into your portable music devices
headset socket and connect the 4 pole end into Aux 4 socket of your hub.
Top Tips (5)
Note: there are two audio leads supplied in Kit L-1, the longest lead has a smaller 3 pole plug one
end for the phone* and a larger 4 pole plug the other end to connect to Aux 3, while the stereo
music lead is the shortest lead and has the same size larger plugs to both ends, however one end
has 4 poles to connect to your Logic hub (Aux 4) and the 3 pole end is to connect to a PORTABLE
music device.
If both your Logic and music device are bike powered you MUST use an ISOLATION
interface lead. See page 17.
Make sure that you plug your music lead into the music systems headset socket and not the line out
socket, or the volume control may not work.
Turn the ignition on. Adjust the
music devices volume control to
about half way and then press
play, (note you need to wait about
10 to 15 seconds after turning the
Logic power on before the music
will be heard) Before holding
the speakers directly and
firmly over your ears listen to
check that the music is not too
loud and adjust as required using
the music devices volume control.
Note that the speakers are slightly
off-set in their housings so try to
align the centre of the speakers
directly with centre of your ear-
holes (with the wire coming out
towards the back of your head).
Apply light pressure to the back of
the speakers and you should now
hear the music very clearly.
Now try to generate as much
background noise as you possibly
can, either by revving the bikes
engine or using a loud TV, hi-fi
system or perhaps a noisy
vacuum cleaner etc, or even all of
them together, as this ambient
noise will simulate helmet noise as
if riding.
Listen to the speakers again with them correctly positioned over your ears and you should hear the music
clearly with virtually no outside noise being heard. This is the ideal speaker positioning and you will notice
that moving the speakers just a small amount away from your ears, or out of alignment (up, down,
backwards or forwards) can easily half the volume and reduce the sound quality, in particular the bass
response, and let considerable external background noise in which will spoil the full potential of sound quality
and performance, especially at higher background noise levels (higher speeds), or when using earplugs.
When you have readjusted the speaker positioning, lightly pressed comfortably over your ears, so that
the music quality is at its very best and you can hear the least amount of background noise coming
through, you have found the best possible speaker positioning and so you now know what to aim
for when fine tuning the speaker positioning after helmet installation.
If you now hold the BEIGE side of the microphone to your lips and project your voice positively through
the loud spot, the VOX turns your microphone on while at the same time automatically reducing the
music level to about 50% to improve communications. When you stop speaking the microphones
automatically switch off and the music gently returns to its original level. Practice this a few times to
become familiar with it, and show your passenger what you have discovered.
Turn the engine off.
Top Tips (6)
If your VOX accidently turns on when you are not speaking due to high noise levels, please slightly
adjust the VOX preset control clockwise until the noise no longer activates the VOX, but be careful
not to turn it clockwise any more that is required or you will make it harder to operate with your
voice.
It’s sometimes a bit tricky holding three parts with only two hands so try pressing one ear to your
shoulder with the speaker in between, leaving your hands free for the other speaker and boom
microphone, or get someone to assist with holding the microphone for you.
