Autocom helmet headsets are designed in two parts.
1 Main headset loom & plug-in speakers (Part 11. HS7-U2)
2 Choice of plug-in booms (Parts 12, 13, 14) Plug in boom microphones.
These headsets are not designed to work with ½ helmets (Chip style)
There are too many different helmets to be able to fully describe every possible installation and so these instructions
are designed as a basic guide. Please NOTE helmets with straps that go directly over your ears do not lend
themselves for a good headset installation, as the speakers have to sit on top or behind the straps, which can make
them uncomfortable or reduce sound quality. Some helmets
do not lend themselves to be installed as we have
shown and may require alternative methods, so please take some time to consider these basic principles and your
helmet design before installation. If you are unsure then please contact your supplier or Autocom. If your system is
not performing as we claim, it is almost certainly due to incorrect installation and/or use.
MAIN HEADSET LOOM SPEAKER (Part 11) (HS7-U2)
This is a twin speaker, stereo headset loom with a short down lead fitted with our 7-pin din plug, for connecting to ou
r
systems. It has a small red socket for plugging in a choice of boom microphones. When this product is plugged into
the rider’s lead of a portable battery powered Pro-7-Sport (Part 4), Easi-7-Advance (Part 2) it activates the battery
power.
Before installing your headset you must first listen to it by plugging it into your powered system, then while holding
the speakers directly over your ears, either play some music or get someone to speak to you through the system.
Doing this is very important to help you to understand what to expect when the speakers are positioned correctly.
Moving the speaker’s just 5mm (1/4”) away from the ears, or out of alignment can easily halve the volume and/o
r
reduce the bass, especially when out on the bike when the powerful helmet noise can overwhelm the speaker sound.
Correct speaker positioning is essential and you will hear this during this test. Use earplugs during this test if you
intend to use them out on the bike, bearing in mind that over attenuating earplugs will impair speaker sound.
Please study the front cover and page 8 illustrations to get the general idea for installing part 11 into your helmet.
Also note the illustrations on page 6, which shows correct speaker and microphone positioning.
If required, tape or glue the rubber joint and/or boom to the outer shell or inner lining so that they are secure.
Position the speakers for maximum comfort and performance then tuck the speaker wires into or behind the lining.
The small red connector is for plugging in one of our boom microphones (NOT required for AVMS, Part 5). You may
find that you need to reposition the speakers, about once a year, due to slight movement that can happen when
putting the helmet on and off your head.
Top tips
You may need to fine-tune the speakers positioning several times
before finding the optimum position for comfort
and performance. Start with the speaker’s low, so as to avoid pressure to the top of the ear and slowly move them up
until you find the optimum position. Try to position the speakers behind the helmet fabric if possible (on top of the
polystyrene). Pack the speakers out to your ears with foam if required. A slight angle out towards the top edge of the
speakers (as shown on page 6) can help with comfort and performance. Normally the speaker wire will come out
towards the back of the helmet.

The fabric is either taped or elasticated
over the polystyrene and so it is easy to
install the speakers behind the lining.
Note that the wire should come
out of the speaker towards

When replacing the cheek

BMW SYSTEM 4 Helmet Instalation
Remove neck collar by pulling the back of the collar away from the helmet and
slide both side guides out from retaining locators
Detatch velcroed flaps (Marked ‘A’ below) to expose the polystyrene ear cups
Thread boom (Microphone first) under the chin strap but over the opened velcroed
flaps(A).
Locate speakers just below the polystyrene ear indents under the velcroed flaps
(B)
Neatly tuck speaker cable under lining around the back of the helmet and below
the neck collar retaining groove, out of sight (C)
Position headset down lead along the outer egde of the helmet under the velcroed
flap. This may require addition velcro to ensure security
Close the velcroed flaps and tidy
Push the thin section of boom into the joint between the skull and cheek lining,
under the chin strap. Locate the boom across the top of left hand cheek pad
forming it to follow it’s contours
Hold boom down firmly and secure in place with velcro pad supplied (D)
Form boom so that microphone is situated in-front of and just touching the center of
your mouth.
Check that down lead and boom are well secured and wires are tidily tucked away.
CAREFULLY check the opening and closing of the front of the helmet does not
snag the boom or down lead.
Test the headset and reposition microphone and speakers if required. Refit neck
collar. Please note that due to the design of this helmet, positioning of the speakers
is limited and as such it may not be possible to position the speakers directly in line
with your ears. If this is the case one cannot expect the sound to be good when
using earplugs.
