Introduction:

The EQUITEL audio over IP devices family allows the transmission and reception of music channels and audio messages over IP, using standard IP network hardware.

These devices provide a unified solution for transmitting audio signals such as background music, advertising and informational messages, to one or more destinations.

By supporting multiple protocols and encoders, these devices are indicated in broadcasting applications, VoIP and Internet radio. In addition to leveraging existing infrastructure and devices such as SIP phones.

The encoder (E421) sends audio input through the Ethernet network. This process is known as "streaming". Streams can also be generated by other devices, like a PC running an application or a SIP phone.

The E495 and E497 desktop microphone consoles can also send vocal messages to the decoders for paging applications. If more than one of these devices are used, they intercommunicate to avoid message collisions.

The E497K is a 24 keys extender for the E495 or E497 desktop microphone consoles.

Decoders (E411, E413 or E415) can receive selected channels (i.e. "streams") from the network and convert it back to an analog audio signal.

Mixer (E417), besides the same features than the decoders, includes the option to use audio coming from files stored in a USB memory or analog signals in its MIC or LINE inputs.

The E430 is a background music and announcements server.

The selection of the actual stream, local file or analog signal to be played is made based on a powerful but very easy to configure priority schema.

The figure shows a schematic of this family of devices usage:

 

The members of the family are:

E411 - Decoder

  • Stereo output in line level (RCA) and headphones.
  • To be used with an external amplifier.

E413 - Decoder with digital I/O

  • Same features as E411 including two digital inputs and outputs for external devices control.
  • Digital outputs can be used to switch ON/OFF the external amplifier.

E415 - Amplified decoder

  • Same as E413 and includes a high quality 25W audio amplifier.
  • Amplified output can be configured in mono or stereo.
  • Line-out output can be used simultaneously.

E417 - Decoder / Mixer

  • With the same characteristics as E415, it can also play sound from files stored in an external USB memory and from its analog inputs.
  • Ideal to mix external background sources with local messages.

E421 - Encoder

  • Line and microphone level inputs for analog encoding.
  • USB input for audio files streaming.
  • Digital inputs for audio encoding triggering.

E430 - Background music and announcements server

  • Generates background music and announcements from internal stored files.
  • High quality MP3 background music.
  • Periodic or scheduled announcements.
  • 60GB internal storage capacity.

E495 - Paging console

  • 12 configurable keys
  • Microphone or pre-recorded messages.
  • Up to 10 units can be used simultaneously, with busy zone indication.

E497 - Paging console

  • 24 configurable keys.
  • Microphone or pre-recorded messages.
  • Up to 10 units can be used simultaneously, with busy zone indication. 

E497K - Extended keyboard

  • 24 keys extender
