The BEHRINGER SONIC ULTRAMIZER SU9920 requires 1U  for installation in 

a 19-inch rack. Please make sure that you leave around 10 cm for the rear 

connections. For installation of the unit in a rack please use M6 machine 

screws and nuts.

There are various ways to integrate the SU9920 into your setup. Depending on 

the application you will need different connecting cables, and these will be 

discussed in the following section.

4.2.1  Cabling with jack cables
To operate the SU9920 in series with other equipment, you will need standard 

commercial ¼" jack cables, often referred to as instrument cables or patch cables. 
These cables have a ¼" TS jack plug at each end. Connect the inputs of the 

equipment with the corresponding outputs of each of the other devices.

If your other equipment has balanced inputs, use a balanced switched cable 

with two stereo jack plugs at the balanced outputs of the SU9920. These cables 

provide a high level of security against interference signals such as noise 

interference from power cables, and they should be used for all long cable routes. 

For connection of balanced and unbalanced plugs,

ring and sleeve have to be bridged at the stereo plug.
