Aer years of research and development, Involve Audio has achieved
a number of technical breakthroughs dealing with the core physics
involved with creating stereo and surround sound that are incorporated
into your Akoustos Y4 Pro Home Stereo System.

Our patented process called Involve™ creates a full surround sound
experience from any stereo source including Television, Internet, mobile
devices, iPods, records, etc. without adding or subtracting any signals

We have created a patented technology called SweetSpot™ that enables
your Involve™ Akoustos Y4 sound system to be enjoyed by everyone
in the room no matter where they are, eliminating the need to nd the

2.1 Y Speaker Positioning
e speakers are marked as
Front Le (FL), Front Right
(FR), Rear Le (RL) and Rear
Right (RR). Face the front of
the room where your front
speakers are to be placed. Le
and Right are taken from this
perspective including the rear
speakers. e diagram to the
le illustrates the positioning
of each speaker. Place the
speakers on the installed wall
mounts, speaker stands or
other raised unit.
Your speakers should be
placed at the same height as
your ears when sitting down.
If they are higher than this
they are best angled down to
send the sound to the centre
listening position.
2.2 Y Speaker Distance & Orientation
Speakers can be placed around the room in front and behind the centre listening
position. Ideally the centre listening position will be in the middle of a room however
this is oen not possible and so place your rear speakers as far to the rear of the centre
listening position as practical.
When orienting your Y Speakers turn the speaker so the outside electrostatic panel is
facing the front and back directly. e distance between the speakers should be set so
that the inside panels face the opposite side of the listen area. is should mean the
panels of each opposing front and back speaker line up and the inside panels are facing
the opposite side of the central listening position.

SweetSpot™ allows you to sit anywhere within the room and still receive a correct stereo
image. To set up this technology rst ensure your Y Speakers are placed and oriented
correctly as shown in sections 2.1 Y Speaker Positioning and 2.2 Y Speaker Distance
and Orientation.
e Front and Rear speakers have separate SST™ Settings to ensure SST™ is operating at
the highest quality. e SST™ factory default setting is 0.5, which covers a wide range
of environments. To set up SweetSpot™ for your listening environment follow the steps
below.
1. Measure the distance from the most o centre seating position to the closest Front Y
Speaker, as shown in the diagram on the next page to obtain the Close Distance.
2. Measure the distance from the most o centre seating position to the furthest Front
Y Speaker, as shown in the diagram on the next page to obtain the Far Distance.
3. Subtract the Close Distance from the Far Distance to obtain the Delay Distance,
refer to the table below and set the SST™™ FRONT dial to the corresponding number.

3.5 Volume
Use the Volume Knob to adjust the system volume, turn clockwise to increase volume
and anti-clockwise to decease volume. e volume can be adjusted from -∞db to
+20db. Try to avoid going above 0db, instead adjust the volume output on your input
device higher if possible. e volume is displayed on the Main Display.
At 0db the system is taking the signal from your device directly with no extra gain.
When above 0db the system must add gain, which can degrade the quality of the
sound. When below 0db the system is removing gain, this does not degrade the quality
of the sound. is is why systems use both negative and positive numbers for volume
control.
3.6 Sub-Woofer Level
Use the Sub-Woofer Knob on the front of the system to vary the bass level of the
system to your individual preference.
3.7 Rear Speaker Level
e volume of the rear speaker can be adjusted with the Rear Level Knob to your
preference.
3.8 Headphones
Headphones can be plugged into the 6.35mm Headphone Socket on the front of the
unit. Before plugging in your headphones into the system turn the volume down below
-10db. Once your headphones are plugged in the Y Speakers and Sub-Woofers will be
muted. You can adjust the volume with the Volume Knob as normal.
