ICM-16/MHI Installation and Operation Manual

INSTALLATION

INTERFACING TO THE STUDIOS

Most likely you have different consoles, headphone amps, and other associated
equipment in each of your studios.  By preparing a setup form, you can help prepare
yourself for the installation.

Using Electronically Balanced Inputs and Outputs

• Electronically balanced inputs and outputs must sometimes be treated different-

ly from transformer coupled inputs and outputs.

• With balanced equipment:

• When the MHI is used with equipment with balanced inputs and outputs of any 

type:

• Be sure polarities are matched (if desired), then connect:

• (+) to hi (+)
• (-) to low (-) ground

•With unbalanced equipment:

• When the MHI is used with equipment having unbalanced inputs 

and/or outputs:

• To use the MHI inputs with unbalanced outputs, connect:

• to hi (+)
• ground (-) input
• ground

• The polarity may be changed by reversing the (+) and (-) connections.

• To use the MHI output with unbalanced inputs, connect:

• (+) to (+) ground

CAUTION!

DO NOT CONNECT
THE LOW (-)  
OUTPUT TO
GROUND!

NOTE:

The polarity may be
changed by reversing
the (+) and (-) connec-
tions. Tie the shield at
one end only. Never tie
each end of the cable
(there are always
exceptions).
