The DAVID PAL36 is
our newest in portable audio-visual entrainment (AVE) devices. What the new
PAL36 offers is 12 more preset sessions than the PAL (30 in all!) and six
empty spaces to store your own personally designed sessions. It is the
same size as the DAVID PAL (approximate dimensions - 2.5 x 1
x 3.5 inches / 7 x 2.5 x 9cm ) and will allow you to experience AVE wherever you go. Perfect for people who are on the go.
Also available is the PAL36 with CES which has the
added benefits and features of CES (Cranio-Electro Stimulation).
- Tru-Vu OmniscreenTM
Eyesets - Our unique Tru-Vu OmniscreenTM
Eyesets were carefully designed to provide you with the most effective and
safe light and sound experience. The Tru-Vu OmniscreenTM
Eyesets for the PAL use eight blue-tinted white LEDs mounted over a silver reflector
behind a translucent screen. This disperses the light
evenly. Our new Tru-Vu OmniscreenTM
Eyesets are specially designed to allow for the left and right visual fields
of each eye to be individually stimulated rather than the entire eye. With
the Tru-Vu OmniscreenTM
Eyesets, the lights flash into the left visual fields of both eyes, then
alternately flashes into the right visual fields of both eyes. This approach
allows the ability to stimulate either visual cortex with a frequency different
from the other visual cortex. For example, a person who functions strongly
from the left brain could have 8 Hz stimulated into the right visual field
(and therefore the left brain) to slow down left brain function and have
18 Hz stimulated into the left visual field to increase right brain function.
- Isochronic Pulsed Tones, Binaural Beats and Chime - The tones of the DAVID PAL36 are
evenly spaced, are of equal pitch and are turned on and off at a specified
rate. This is important to enhance the effectiveness of audio entrainment.
- The gradual lowering of the lights and tones at the end of the session
prevents a startle response (also known as somnatic shock). Soft-OffTM
ensures that relaxation and other benefits carry over even after a session
- Battery Power Indicator - At a quick glance you can tell if your
battery has enough power to run your session. New eyeset technology
allows for much longer life for your 9-volt battery.
- Easy-To-Find Intensity and Volume Buttons
- The intensity and volume buttons are raised so that you
can make the necessary adjustments easily and quickly, even with your eyes
closed. Adjust the intensity
of the OmniscreenTM
Eyeset with the easy-to-find INT button.
- 30 Preset Sessions -
Including Brain Brightener (for ADD and cognition), Fractioned Hypnosis,
Alpha/Beta Mix (for depression), Schumann with Dissociation & HRV (for

The heart speeds up with every breath in and slows down with every breath
out. This swing in heart rate is HRV. A typical heart beat swing is in the
order of about 15 beats per minute (bpm). When people get stressed, the heart
typically clamps to sometimes as low as five bpm HRV at times intermixed with
sharp spikes in heart rate. This is all abnormal activity and is rough on
The HRV technique used clinically is based on a 10 second breathing cycle
(six breaths/minute, by inhaling slowly for five seconds and exhaling slowly
for five seconds in an easy, relaxed breath). When using HRV paced breathing,
listen to the heartbeat generated by the DAVID PALTM
through the headphones. Inhale for two heartbeats and exhale for two heartbeats
(not your own heartbeats!). Most sessions begin at seven breathing cycles/minute
(28 heartbeats/min) and slow to six breaths /minute (24 heartbeats/min). This
allows the user to breathe a little faster at the onset of a session until
he/she has had time to relax.
