The Telco Mixer HL 204 is the most advanced solution for over-the-air conferencing between cell phones,

land lines and digital SIP telephony.

Replaces the old analog telephone hybrids with a system created for the radio of the digital era.

Combines all communication technologies in a stand-alone 4-channel system, allowing conferences

and can make conferences between them by means of a single attenuator of the console.

Two HL 240 units with summing cables provide 8 channels over a console attenuator.

It is the only system to offer VQR technology for sound quality restoration.

This invention allows to reconstruct, by means of a delay-free processing, the original sound of the person

to the original sound of the person talking on the phone or cell phone, including WhatsApp communications.

It uses the harmonic spectrum of the signal to recover the dynamic range, bass and treble that were lost.

We recommend listening to the audio demos below.

The HL 240 provides simple operation with illuminated buttons. Incoming calls are indicated by a flashing light and are answered by pressing the button and cut off in the same way. Even cell phones operate in this way, allowing the cell phone to remain in the hands of the announcers at all times. Even the cell phones operate in this way allowing the cell phone to be always in the hands of the announcers. You can talk in private, without going on the air, by pressing Talkback which includes an internal microphone and then leave the calls on hold listening to the on-air program until the moment when we open the attenuator of the console and each of the 4 calls go on the air separately or in conference because each one has its own attenuator.

In the same way the communications coming from the two cellular phones are seen flashing on the connection button. By pressing the button they are answered from the HL 240 or they can also be answered and operated from the cell phone and then transferred to the Telco Mixer. Always have communications in your hands... no matter where they come from!

Advantages of Bluetooth cellular communications

The HL 240 offers this technology that we have been pioneering since 2010.

1- The cell phone call with WhatsApp enchants listeners because they can talk to the radio at no cost from anywhere they are. It has great sound quality because the connection is DIGITAL and also the HL 240 can restore it to original voice through the VQR. The Bluetooth has a response that covers the entire vocal range. From the cell phone can be armed conferences of several people.

2- The star journalist of your radio station will have a formidable tool that will allow him/her to connect to the private cell phones of politicians, businessmen and media stars to make reports to those who keep their number secret. Remember that these VIPs only answer calls coming from a known cell phone.
