A new version of the unit and some explanations:
This is a stereo unit. That should be obvious, but for anyone who is not familiar with binaural beats it might not be. This unit is just two sine oscillators that are hard panned one to the left, one to the right, but the right oscillators frequency is influenced by the “beat” parameter where you can choose the exact Hz frequency difference between the left ear and the right ear. Supposedly, listening to a 5Hz difference of frequencies in your left ear and your right ear, should “tune” your brain to that frequency. When changing the “beat” parameter, you will hear movement in the sound that is not actually there (more rapidly as you increase the frequency difference). So your brain is making that up. In that way you can use it as a meditation aid, or for brain experiments if you’re into that sort of thing The great thing about doing this with the ER-301, is that you can actually sequence the tone without loosing the exact frequency offset, and combine it with other sounds to make the binaural beats less well, monotonous. That is the idea at least. Thanks to @odevices to make it actually work! And @Joe for chiming in. @sixnon try the new version, it should be accurate.

The “beat” parameter takes a bi-polar offset signal from -15 to 15, where 0 gives you a perfectly balanced tone in both ears. As you increase or decrease the “beat” parameter, the right oscillator will start offsetting resulting in the perceived wobble of the tone.
This is a little brain map for your entertainment:
Epsilon < 0.5 Hz
Super normal abilities, expanded consciousness, ‘suspended animation’ with no perceivable heartbeat, respiration or pulse
Delta & Sub-Delta:~ 0.5– 4 Hz
Deep dreamless sleep, immune enhancement, regeneration and healing; anti-ageing hormones, cortisol reduction and pituitary release of H.G.H.; extremely deep relaxation
Theta: ~ 4 – 8 Hz
Memory consolidation; creativity, imagery and visualization; free-flowing lucid thought; spatial navigation tasks; inspiration and intuition; REM; processing of new (episodic) information; emotional processing and heightened suggestibility.
Alpha: ~ 7.5 – 12.5 Hz
Information processing; relaxed, tranquil consciousness and inward awareness; creative flow states; the coalescence of different frequencies; enhanced HRV, serotonin production, memory and dream recall; reactivity to disturbing noises in sleep
Sensorimotor Rhythms (SMR): ~ 12.5 – 15 Hz
Physical and mental calm; non-impulsive, external awareness; improved energy levels; flow states; healthy sleep patterns
Beta: ~ 15 – 40 Hz
Focused, analytical, rational, wide awake, alert awareness; concentrated, focused mind, heightened sensory perception, emotional stability, visual acuity, cognitive control of motor activity
Gamma: ~ 38 – 100 Hz
Integration/synchronization of brain centres involved in learning, memory, thought generation, task processing, motor function and sensory binding; heightened creativity, comprehension, concentration and impulse control
Lambda ~ 100 Hz +
Largely unknown but may include brain timing, higher states of awareness and ‘super-normal’ abilities
