AEQ TALENT

1. INTRODUCTION.

1.1. General description.

AEQ TALENT is a single-channel audio codec with professional microphone input and

headphone output. Also, it counts with auxiliary 3.5mm jack line input and output and Bluetooth

connectivity.

AEQ TALENT is optimized for OPUS encoding algorithms, but it is also compatible with other

AEQ and third-party audiocodecs, as it also features AEQ LD Extend modes and the mandatory

algorithms according to EBU-TECH 3326 specification from EBU N/ACIP work group.

When connecting to another AEQ codec, users can take advantage of an exclusive set of tools

that makes initiating communications and control of the unit a simple task:

•The "SmartRTP" proprietary call-initiation protocol that simplifies connection to compatible

codecs.

•"AEQ ControlPHOENIX", remote control Software that allows for the remote operation and

adjustment of the unit from your station. ControlPhoenix allows you to control everything

related to the call initiation process and also the adjustment of all audio parameters and the

local audio routing of TALENT.

•It is also possible to control the unit using "AEQ TALENT PILOT" App for Android and iOS,

running on a Bluetooth-linked smart device. It is also possible to transfer audio between a

smart device and TALENT audiocodec.

•"HELP" function, that allows the journalist to use the system to request for assistance from

the station when facing an unexpected situation.

It is recommended to carefully read this manual and the "AEQ ControlPHOENIX" user’s

guide before using the unit, although chapter 6 offers a quickstart user’s guide.

3G / 4G / 5G telephony: a 3G, 4G or 5G modem can be connected to the IP

interface.

Wireless data links: a "wireless bridge", WiMax or WiFi antenna can be

connected to the IP interface.

Other Features:

-Local interface with keys and encoders.

-Three-level LED vumeter at the front panel for program TX level indication.

-Received audio signal presence indicator.

-Operating temperature: -10 to +45 º C (14 to 114 º F).

through USB interface. Power consumption: 3.5 W max.

AEQ offers the "SmartRTP"call initiation protocol in order to greatly simplify the

operation of the audiocodec.

AEQ also offers two SIP servers free of charge as a standard service for the users of

Phoenix ALIO. One of them is configured as main and the other is provided as a backup.

More information can be found in Appendix B.

AEQ TALENT

1.6. Compatibility with third-party codecs.

TALENT is a portable IP audiocodec compatible with EBU-TECH 3326 technical specification

from EBU N/ACIP workgroup. This technical specification was developed to guarantee

compatibility between equipment from different manufacturers in applications for professional-

quality audio contribution over IP networks. Therefore it is possible to connect TALENT with any

codec from other manufacturer over IP provided that this unit has been developed according to

N/ACIP (please check third-party codecs technical specifications).

2.2.3. "RESET"pushbutton.

This push-button allows the user to reset the device configuration in several ways, according to

this sequence (for this there must be no call established on the device):

1) Hold it pressed until a “beep” is emitted. If the push-button is released at that moment,

the unit will return a different confirmation tone and will return to DHCP mode, without

any further changes.

2) If the push-button is held pressed for a longer time until it emits 2 beeps, and it is

released at that moment, the unit will return a different double confirmation tone and will

reboot adopting the following default Ethernet configuration: 192.168.1.89 fixed IP

address (DHCP mode is turned off), /24 network mask (255.255.255.0), 192.168.1.1

gateway and 8.8.8.8 DNS server, without further alteration.

3) If, the push-button is held until the unit beeps three times and then released, after a

different triple confirmation tone it will perform a full FACTORY CONFIGURATION

RESET, although ONLY the following parameters will remain unchanged:
