Rear view of Version 2 Steelhead showing cable spread measurements. (Click on the pic for a bigger rear view.)
Your phono input cables need to be able to spread 9" apart.
Your LINE input RCA cables need to be able to spread 12.250" apart.
Your Output cables need to be able to spread 15" apart.
The chassis itself is 17" wide. The faceplate is 19" wide.
This is a picture of the Steelhead Power supply. You can hide it somewhere out of the way.
As of November 2005 the PSU has a BLUE LED instead of a RED one. Because you asked
