1. INTRODUCTION

Audio interface with IP connection for COMPACT System.
Incorporates a module of 2 configurable analog audio inputs for music or announcements and a module of 2 output zones with DSP
and monitoring functions.
Main characteristics:

Dual Ethernet connection for installations with redundant
network systems. The connection is constantly monitored
and switches automatically when required.

It is equipped with two power supplies for redundant
installations (primary at 100-240Vac 50/60 Hz and
secondary at 24 VDC).

Two analog audio inputs configurable such as music input
or announcements.

Two zone outputs Incorporates DSP and monitoring
functions.
DSP functions:
Controls for volume controls, bass and treble or 10-band
graphic equalizer (30Hz / 60Hz / 125Hz / 250Hz / 500Hz /
1KHz / 2KHz / 4KHz / 8KHz / 16KHz) controlled by means
the Call Point software
Monitoring functions:

Monitoring of the speaker line: To accomplish this the
card injects different frequencies in the speaker line; it
then collects and analyses these frequencies to
determine the condition of the line (line open, short-
circuit, low impedance, high impedance or line in good
condition).

Monitoring of the condition of the amplifier by
analysing the audio signal to detect if the power stage has
entered into protection mode or is turned off and by
detecting the 24 VDC it receives from the amplifier.

Front USB input for music.

CAN bus for communicating with the peripherals (NS-
CAN, MD-30C, ME-200C).

Reception of digital audio via an IP connection (4
simultaneous channels).

IF-722ETH

Reception and sending of control data via an IP
connection.

Monitoring of the operation of the equipment using Call
Point software and/or basic TELNET or SSH (Secure Shell)
functions.

Configuration of the IP address in Flash memory via
software.

Constant notification (IP) of the status of the equipment
via a Heart Beat signal.

Pre-recorded messages residing in the equipment that
can be remotely updated using the Call Point software via
IP located in the internal Micro SD memory (16 GB).

Monitoring functions:
- of the speaker lines (short-circuit and open line).
- of the amplifiers.
- of the primary and secondary power supplies.
- of the input contacts.
- of the pre-recorded messages.

Communication with external systems:
- VoIP: receiving of direct calls from any VoIP digital
telephone
Incorporates zone selection by sending DTMF tones.
Provides the possibility of protecting the access with a
password.
- Direct integration (XML, API/DLL).
