DAVID Pal Audio Visual Entrainment w/HRV
DAVID PAL AVE
Meet your latest PAL. That's what we've named our latest addition to the DAVID family, the DAVID PALTM (Portable And Lightweight). We're very excited about our latest creation with our newest and best preset sessions programmed into it and it's half the size of our other audio-visual entrainment (AVE) models. It even has heart rate variability (HRV) to help you breathe as well as a meditator can.
The DAVID PALTM is an extremely portable audio-visual entrainment (AVE) device. This is the one that will fit in your shirt or jacket pocket (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.
AUDIO-VISUAL ENTRAINMENT (AVE):
To ensure safe, gentle and effective audio-visual entrainment (AVE), the DAVID PALTM offers the following:
- 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 light blue lights 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 PALTM 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.
- Soft-OffTM - 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 has ended.
- 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.
- 18 Preset Sessions - Including Brain Brightener (for ADD and cognition), Fractioned Hypnosis, Alpha/Beta Mix (for depression), Schumann with Dissociation & HRV (for meditation), Beta Perker, Theta with Dissociation (for sleeping), and Sound Sync (to turn your music into an intriguing light show).

HEART RATE VARIABILITY (HRV):
For the first time ever, a system exists where meditative breathing may be paced along with an audio-visual entrainment (AVE) session. This technique has been borrowed from our clinical model, the DAVID Paradise XLTM. Long, graceful breathing cycles have been used as part of meditation. Scientifically, this technique has been analyzed and shown to settle down a stressed autonomic nervous system. Both sympathetic (flight-or-fight) activity and para-sympathetic (the brain’s efforts to compensate) activity settle down dramatically using HRV techniques.
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 heart.
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.
