This system can monitor and share the experience of two people’s left, right and coherence brainwaves : use  CH 1, CH 2, CH3 and CH4.

System include :

two sets of:

head pad, cable, head band, electrode, Bluetooth IBVA (one ‘F’ and one ‘M’ type), 9V alkaline battery, carry case with one 2 meter stereo mini jack audio cable.

Software :
IBVA4 DVD

                           all package                                             content of one package

Setup procedure:

1: Remove the two 2P short pin connectors from 6P connector input of ‘F’ type IBVA unit. It says on the front “CH 3-4 INPUT”

2: Next insert a battery into the F type unit and into the M type unit.

3: Turn the power ON only for the F type IBVA, then make ‘pairing; with F type. Don't make pairing with M type.
Make sure there is only one IBVA Bluetooth port name in the Mac system.

4: Connect F type and  M type IBVA units using the stereo mini jack audio cable.

5: For both systems :

Snap on 3 new electrodes inside the head pad, peel off the protective film from each electrode, they must be moist and sticky to ensure good contact and signal. Next attach it to the forehead, locating the central electrode to the centre of the forehead, you can secure further with the soft head band over the outside around the head.

Position the head pad with the connectors on your left side.

Ear ‘ground’ cable connects to the left ear.

Follow the white dots on the cable, corresponding with the white dots on the headpad, connect the cable to the head pad and the other end to the CH 1 ( Left ) and CH 2 ( Right ) input of IBVA Bluetooth unit ( white dots face up )

Connect cable to head pad and CH 1 ( Left ) and CH 2 ( Right ) input of IBVA unit.

Do the same for F type and for  M type

                       F type IBVA                         M type IBVA

6: Install IBVA4 main application from the DVD to Mac Hard Drive, also install the QC plugin, AU plugin and sample files.

Turn the power ‘ON’ for both IBVA then Run IBVA4 and setup 4 ch device and select port for access CH 1, CH 2, CH 3, CH 4.

Preferences / Device / Hardware setup / select 2 set of L & R (1, 2, 3, 4 CH)

When using the  4 channel display mode, you need to use a high speed Mac system.

( minimum 2 GHz Core Duo, nice speed with 3GHz Quad Mac Pro )

=======================================================

How "two person IBVA system"  works :

An Bluetooth IBVA headset is connected to each person.

The two Bluetooth IBVA are connected by stereo mini jack cable.

Limited distance between the two people depends on this cable length

A 2 meter wire is included, this also works using a 10 m to 20 m standard audio mini jack cable. (signal level is 0 .. 5 V )

The signal output impedance (M type IBVA) is 100 ohm, the frequency range is DC to 2 KHz.

M type Bluetooth IBVA unit sends Channel 3 and Channel 4 to F type Bluetooth IBVA unit.

The Mac communicates with the F type Bluetooth IBVA unit.

The F type Bluetooth IBVA unit sends Channel 1, Channel 2, Channel 3 and Channel 4 to the Mac via Bluetooth.

This system can be used in the following ways:

1. Mac A  can be paired with the F type Bluetooth IBVA unit to be used as a standard 2 channel system,  exclusive use for the functions needed to ‘Brain VJ’.

2. Mac B can be paired with M type Bluetooth IBVA unit, to be used as a standard 2 ch system. exclusive use for the functions of ‘Brain DJ’.

Shows :

CH 1 ( person 1 left brain ), CH 2 ( person 1 right brain ) and CH 1 & CH 2 coherence

CH 3 ( person 2 left brain ), CH 4 ( person 2 right brain ) and CH 3 & CH 4 coherence

CH 1 & CH 3 coherence : coherence between person 1 left brain and person 2 left brain

CH 2 & CH 4 coherence : coherence between person 1 right brain and person 2 right brain

CH 1 & CH 4 coherence : coherence between person 1 left brain and person 2 right brain

CH 2 & CH 3 coherence : coherence between person 1 right brain and person 2 left brain
