What is the difference between single channel and dual channel headphones
Dual channel headphones are an important feature if you wish to watch two DVD's at the same time in the back seat. Please note all headphones from OnFair are dual channel headphones.
Dual channel headphones are equipped to receive the IR (infrared) signal on two frequencies. Typically they are simplified to channel A and channel B. We always recommend setting up one headrest to channel A and the other headrest to channel B. Then setup your headphones to channel A and B accordingly.
The IR signal from the headrests to the headphones is a "Line of sight" singal meaning you need to be sitting directly behind or within less than a 30 degree position to receive the IR signal.
We have many large families who wish to install 4 headrests into one vehicle. We always recommend alternating the A/B audio signals from left to right. Meaning that in the middle seat have channel A on the left and channel B on the right side. Then in the back seat, alternate it so channel B is on the left side and channel a is on the right side. We're told this works well at reducing any overlap and signal interference.
OnFair is the leading online provider and most passionate about offering only the best headrest DVD players on the market. They work directly with factory engineers to design and develop the most advanced features and capabilities available and then offer them to you in their exclusive AUTOTAIN branded headrest monitor packages.
Because they've been doing this for over 11 years as a family business from Lincoln, Nebraska, some would argue they've earned their PHD in headrest DVD players as it'll be nearly impossible to find anyone more passionate and more experience with the product.
