Hello. We have a headphone with subwoofer out kit. Though it doesn't say on the website that it is compatible with MBr it is.

Here is the link. http://www.pinnovators.com/catalog/product_info.php?products_id=79

Let me know if you have any other questions and we'll be happy to help.

Thank you.

Since my OP we have discovered that CGC changed the board sometime during production so if interested in a kit please message us so we can be sure to get you the correct kit. Thus far we think it was just on the LE. We are keeping track of serial numbers as customers message us so we can try to discern when the change was made.

In addition, the link has changed as we launched our new website on 11/1. Here is the new link https://pinnovators.myshopify.com/pages/monster-bash-remake

We make a headphone kit with subwoofer output. Here is a link to our PinPAC 7 https://pinnovators.myshopify.com/pages/monster-bash-remake. We have two different ones available depending on which rev your MPU is.

The PinPAC 7 allows you to control headphone volume but not system volume. You can also mute the external volume while using headphones.

Feel free to PM me if you have any questions.

Thanks.
