Polarity
Positive pressure on AMS microphone diaphragm produces
positive voltage on pin 1 (+) with respect to pin 2 (--) at Output.
Send inputs to all outputs are non-inverting. AUX input to all
outputs is inverting.

Certifications
AMS8100: UL and cUL listed under UL813, CSA C22.2 No.1
AMS8100E: Conforms to European Union directives, eligi-
ble to bear CE marking; VDE GS-Certified to EN 60 065;
meets European Union EMC Immunity Requirements (EN
50 082--1, 1992).
CE Certification Note:
The extreme sensitivity of the
Direc-
tional Intellimix
circuitry may allow some channel gating due
to static discharge or abnormal electrical disturbance to the
power or signal lines. The unit will not be damaged: normal
operation will resume after the disturbance ceases.
