J-Rak™ Rackmount Adapter
SETTING UP THE J•RAK 8
Step One: Remove the Shell
To begin, remove the protective outer ‘book-end’ shell from the Radial
product by unscrewing the four (4) hex #6/32 screws. A hex allen key
is provided for these screws. Do not discard the screws or shells.
Store them in a safe place in case you want to restore the product
to its original con guration.
Step Two: Load into Slot
With the outer shell removed, slide the enclosure into the front of the
J•Rak 8 slot. Ensure the open side is facing up as pictured below.
Step Three: Rear Screws
Once the enclosure is seated in the J•Rak 8 locate the two screw
holes for the slot on the top near the rear edge. Sixteen Philips head
screws are provided to secure enclosures in place. Insert two screws
per slot. Repeat the procedure for the other slots. The J•Rak 8 is now
ready to mount in your 19” rack.

PRODUCT DESCRIPTION
The Radial J•Rak 8 requires two rack spaces (3 ½”) and allows up
to eight Radial products to be rack-mounted in a standard 19” rack.
The J•Rak 8 is designed to allow touring companies to make better
use of their DI box inventory by allowing stand-alone units to be
converted to rackmounted DIs for applications like keyboards. A wide
range of Radial interface and mic-splitter products are compatible
with the J•Rak 8 making it possible to quickly create a custom rack.
A strong advantage for the J•Rak 8 is that you get to choose what
connectors face front. Before you start loading up DIs take a minute
to consider how you will connect to them. Depending on your situa-
tion you may prefer to have the inputs face front. This would be best
for studio applications where instruments are often connected and
disconnected during a session.
GUITARS AND BASS
The 1/4" inputs face front allowing
easy connection for instruments.
J•RAK
If you’re using the J•Rak 8 in a concert touring situation then you may
want the outputs to face front for quick connection to a microphone
snake. The J•Rak 8 lets you choose the orientation for each slot so
you may want to think about which arrangement is best for your setup.
KEYBOARD RACKS
The XLR outputs face front for connection
to mic snakes and mixing consoles.

tion and a baked enamel nish for years of trouble-free performance.

to protect against manufacturing defects.
