Rack Ear Kit Installation Instructions

The Rack Ear Kit allows the Onyx 1620 mixer to be mounted in a standard 19" rack, where it will look rather super. The 

mixer will take up 12 rack spaces, and you should allow an extra 1 or 2 rack spaces above to make your connections. The 

kit contains two rack ear brackets and four screws (longer than the original screws, with a captive washer).

Tools Required:

One Phillips screwdriver.

Procedure:

1.  Turn off the mixer, and disconnect the power cord, and all connecting cords.

2.  Place the mixer face up on a soft and dry flat surface.

3.  Remove the four screws as shown below, and keep them in a safe place for further use. Do not remove the middle 

two screws on each side, as these remain in place. If you are not planning on using the old screws again, take them 

down to your local recycling plant. They may give you some money just to go away. 

4.  Using only the new screws supplied, secure the rack ear brackets to each side of the mixer as shown. Hand-tighten 

the screws securely. The brackets are identical, so it does not matter which one goes on which side.

5.  Offer up the mixer to your rack and secure it in place with eight rack screws (not supplied). Remember to leave 

enough room at the top so you can easily make your connections.

6.  That's about it really. Take the rest of the day off; you have done well.
