The rear panel provides a comprehensive and flexible set of summing input
connections. Connections include:
• Line inputs
• Insert sends and returns
Summing Input Line Input Connections
The line inputs for the sixteen summing inputs are distributed on two DB-25
connectors.
Summing Input Insert Connections
All insert sends and returns are balanced, low-impedance, line-level signals routed via
¼” tip-ring-sleeve jacks on the rear panel.
The insert send is fed immediately after the input on summing inputs 1-16.
INSERT SEND: ¼” tip-ring-sleeve, balanced, low-
impedance, line-level
INSERT RETURN: ¼” tip-ring-sleeve, balanced, low-
impedance, line-level
SUMMING INPUTS 1-8: DB-25, balanced, low-
impedance, line-level
• Standard pin-out: 1-8=summing inputs 1-8
SUMMING INPUTS 9-16: DB-25, balanced, low-
impedance, line-level
• Standard pin-out: 1-8=summing inputs 9-16
