SM58 Rev. 4.00 AA36-100 Digital ICS Tie Line Adapter Manual

Section 1.0 Description

1.1 Introduction

This manual contains information on the AA36-100 Digital ICS Tie Line Adapter.
Information in this section consists of purpose of equipment, features and specifications,
and unit nomenclature.

1.2 Purpose of Equipment

The AA36-100 will allow any NAT audio intercom product with an ICS tie line or
SuperNAT tie line to be interfaced to other proprietary bi-directional and uni-directional
ICS tie lines.

Typically, the AA36-100 is used to add NAT intercom/audio systems to an existing
system that is not manufactured by NAT.

The AA36-100 can be set to work in a number of installation configurations. The typical
application would have an NAT ICS tie line (or SuperNAT tie line) being interfaced to
another ‘universal’ bi-directional tie line (e.g. dB Systems, Gemelli, Andrea, etc).
Alternatively, the NAT tie line can be interfaced with the ‘universal’ uni-directional tie line
(e.g. mic and phones).

1.3 Features

The AA36-100 is designed to be easy to install and set up.

The AA36-100 accepts intercom bi-directional audio from the NAT standard ICS tie line
(340 mVrms into 2 kOhms), and can accommodate up to three NAT loads in parallel. In
Nat Super tie mode (1.2 Vrms into 2 kOhms), up to 3 Nat Super tie loads are allowed.

At installation or service, the following functions can be adjusted to suit the user:

• the universal microphone output levels (but not impedances)

• the universal bi-directional ICS tie line output levels and impedances

• the attenuation of the analog audio signal arriving on the universal ICS tie line or

microphone input

• the attenuation of the analog audio signal arriving on the NAT ICS tie line

• the output level of the NAT bi-directional ICS tie line

• the universal bi-directional tie line can be configured to one of 4 possible proprietary

tie lines

On power up, a burst of white noise is generated on each bi-directional ICS tie line,
along with a short tie line identification message.
