AA-JA11112 is an interface extension board in compact size for use with JAB1 / JAB2 to provide customers with a simple panel amount solution. It provides a 3.5mm AUX IN port for line input, 2CKTS USB ports for powering other devices, a switch button to control the system and LED indicators to have a better overview of the system condition. The connection is very easy. The only thing you need to do is to connect this board with JAB1 / JAB2 via a 10pin cable. When this extension board is connected with JAB1 / JAB2, it will be powered by JAB1/ JAB2, so there is no need of an extra power supply, which is convenient and saves much space.

Panel Amount Solution

With the pre-mounted interfaces, this extension board can be a panel amount solution for Jukecase, Boombox and portable Bluetooth speakers with JAB1 / JAB2.

Available for BC1.2 Protocol

The 2-port USB charger on interface extension board supports USB charging specification, revision 1.2 (BC 1.2) which could automatically config D+ and D- lines connections for an attached device. This interface extension board automatically adjusts its output level based on the connected device. It is compatible with smartphones and tablets from Apple, Samsung, HTC, Google and BlackBerry. In addition, this extension board can charge up to two devices at the same time, which can get more output than ordinary dual-port chargers. A maximum output of 5.25V/2.1 A brings you to a whole new level of high-speed charging.

Hi, alex. Thank you for your interest in our products. The USB port on this interface extension board outputs 5V 2A. You can see if it's suitable for your LED strip. Wish this could help you. Have a nice day~

Is there a way to have only the AUX jack? not the usb or indicator...

Hi, Frédéric. Do you mean that you want an extension board with only the AUX jack? We don't have such product now. If you want, we can customize for you. Please note MOQ is required. If you are interested, please contact with store@sure-electronics.com for further discussion. Or you can use the 3.5mm AUX cable, which don't have the panel. Wish this could help you. Have a nice day!

Hello ,what does exactly do the switch? Jab2 power standby or input selector? Does exist any extension board documentation ? Thanks

Hi, Simone. The switch on the AA-JA11112 is used for mute control of JAB2. We have uploaded the connection diagram and manual to the detailed page of AA-JA11112. Wish this could help you.

Can this work with 1 X 100 WATT CLASS D AUDIO AMPLIFIER BOARD W DSP - JAB3-1100?

Hi, Thierry. Thank you for your interest in our products. The Interface Extension Board (AA-JA11112) can't be used with WONDOM JAB3. Wish this could help you.
