1. INTRODUCTION

The inherent routing exibility of Audio over IP (AoIP) provides great

advantages over traditional audio cabling solutions while using highly cost

e󰀨ective Cat.5e cable. This greatly reduces the cost of wiring large systems

and improves control convenience. This unit takes full advantage of the core

benets provided by AoIP and adds support for dual audio output formats,

including both analog (balanced speaker output) and digital (optical S/

PDIF). This product allows you to easily receive extended audio sources

from compatible audio transmission devices located anywhere on the local

network.

Standard control is provided by front panel controls, WebGUI, and Telnet.

Advanced control and system integration is possible using the optional IP

Master Controller.

2. APPLICATIONS

• Home Theaters

• Classrooms

• Lecture Halls

3. PACKAGE CONTENTS

• 1× Audio over IP Receiver

• 1× 5V/1.2A DC Power Adapter

• 1× 3-pin Terminal Block

• 1× 5-pin Terminal Block

• 1× Operation Manual

4. SYSTEM REQUIREMENTS

• Audio receiving equipment such as headphones, audio ampliers or

powered speakers.

• A Gigabit Ethernet switch with “IGMP snooping” enabled is required for

multicast support.

• An active network connection from a switch or router that supports PoE

(802.3af) to power the unit is highly recommended.

5. FEATURES

• Analog output: 1×Balanced stereo output

• Digital output: 1×Optical output

• Reception of extended audio and RS-232 over TCP/IP in unicast (point-to-

point) or multicast (single-to-many) modes

• Reception of extended AoIP signals can be further extended (up to 100m

per segment) by using gigabit network switches.

• Volume control for the analog audio output

• Compatible with the IP Master Controller to allow integration with existing

compatible TCP/IP video matrix networks.

• Field-upgradable rmware

• May be powered directly by Power over Ethernet (PoE) when connected

to a Gigabit Ethernet switch that provides PoE (802.3af)

• Standard control is provided by front panel controls, WebGUI, and Telnet.

Advanced control and system integration is possible using the optional IP

Master Controller.

1PWR LED: This LED will illuminate to indicate the unit is on and receiving

power.

2LINK LED: While the receiver is attempting to establish a network

connection the LINK LED will ash. When the receiver has established a

stable connection the LINK LED will illuminate solidly.

3OPT/LINE/MIC LEDs: The illuminated LED indicates which source is

currently selected on the linked transmitter.

Note: Only active when linked directly to a compatible dedicated audio

transmitter.

4MUTE LED: This LED will illuminate when audio output is muted.

5CH-/CH+ Buttons: Press these buttons to increase or decrease the

streaming channel used to receive audio from the local network.

Note: If only one channel is detected, the channel number will not

change.

6MUTE Button: Press to toggle between muting and unmuting the audio

output.

7VOL -/+ & AUDIO SELECT Knob: Turn this knob to increase or

decrease the audio volume level of the analog output. Press the knob in

to sequentially switch through the available audio sources on the linked

transmitter.

Note: Input selection is only available when linked directly to a compatible

dedicated audio transmitter.

with a 3-pin adapter cable for the reception of RS-232 signals from a

compatible transmitter.

4LAN(POE) Port: Connect via a Gigabit Ethernet switch to compatible

receiver(s) to transmit data, and to a PC/laptop to control the unit via

WebGUI.

Note: This unit can be powered directly by the connected Gigabit

Ethernet switch if it provides PoE (802.3af).

5DC 5V Port: Plug the 5V DC power adapter into the unit and connect it

to an AC wall outlet for power. (Optional if powered by PoE)

• Device Discovery

Please obtain the “Device Discovery” software from your authorized dealer

and save it in a directory where you can easily nd it.

Connect the unit and your PC/Laptop to the same active network and

execute the “Device Discovery” software. Click on “Find Devices on Internet”

and a list of devices connected to the local network will show up indicating

their current IP address.

Note: This unit defaults to Auto IP mode. The current IP address can be

veried using the Device Discovery software.

By clicking on one of the listed devices you will be presented with the

network details of that particular device.

1) IP Mode: If you choose, you can alter the static IP network settings for

the device, or switch the unit into DHCP mode to automatically obtain

proper network settings from a local DHCP server. To switch to DHCP

mode, please select DHCP from the IP mode drop-down, then click “Save”

followed by “Reboot”.

2) WebGUI Hotkey: Once you are satised with the network settings, you

may use them to connect via Telnet or WebGUI. The network information

window provides a convenient link to launch the WebGUI directly.
