Question

How do I hook up my Eris 4.5 monitors with a Focusrite2i2 with HP Desktop computer with Windows 7?

Answer 1

The Scarlett 2i2 has 2 x TRS Balanced outputs (Stereo L / R). The Eris 4.5 has both L / R TRS Balanced inputs and unbalanced RCA inputs. Use TRS Balanced 1/4" cables to connect the two.

Refer to the Eris 4.5 owner's manual for hook up guide on Section 2.3:
