The centerpiece of a mastering system allowing control of up to eight pieces of outboard gear.

Winner of the 2009 TEC award, the Manley BACKBONE Mastering Insert Switcher accepts up to three balanced source inputs, selectable on the left side. Left and right can be reversed and Abolute Polarity can be flipped. The 24 position input & Output gains can be switched active or left passive. Up to 8 inserts can be switched in or bypassed. A Sum - Difference MS Matrix can be addressed between inserts 2 and 3. The order of inserts 4 & 5 can be swapped. The Manley Backbone is an injection point between inputs 7 & 8 to allow for several functions on the 3-Function mix - Fade output control. You can mix in the Difference signal from the input. This mixes in some out of phase signal from the input to the output in order to widen the image if desired. OR you can mix in a parallel signal in between inserts 7 & 8. A lot of folks run a reverb or parallel compressor in this fashion. Or you can use the knob as a fader to make smooth and accurate level fades with the Penny & Giles rotary fader.

This Manley Backbone comes with DB25 connectors for the INSERTS I/O. Cables sold separately.
