two telephone hybrids, the D612 can work on studies 
that otherwise would need consoles of high price



Connection between studies in model D612/AoIP 


Using the model D612/AoIP you do not have even need to add new cables to link the studies because the fact that the output of the 
console will be sent as digital streaming to the same Ethernet LAN that links all your PCs. 
Signal can be send to studios where it will be received on a PC or via an ADA102. 
The delay is less than 10 milliseconds and the audio quality is 100% Digital


The Ethernet input of the D612/AoIP model 
connects directly to the LAN 
like a PC. 



D 612 features advanced internal phone hybrids 


The communication with the audience is now the essence 
of modern radio. 
The D 612 can handle calls from audience 
and talk privately with the caller. 
Handles telephone and cellular communications and can perform
simultaneous conferences. 

Also can do long distance calls, by Internet using Skype. 

No other console on the market offers these features!


D 612 lets you using a telephone set next to the console. But if you do not use it, is also possible to answer incoming calls by pressing a button at console 

The cellphone is connected by Bluetooth wirelessly. This  achieves higher sound quality. 

The Bluetooth connection avoids cables and allows that the cellphone will be located several meters away from the console in a place that has better signal reception. 
Any cellphone is connected in seconds to the D612!


Advantages of working with Bluetooth

The D612 console is the first at the international market to offer the remarkable possibility of having cellphone Hybrids with Bluetooth link
This provides significant operational advantages for journalism because it is possible to connect the console in seconds with the journalist  private cellphone. This allows doing an interview with people whose telephone numbers are confidential, and the journalist of course do not want to reveal 

We can imagine a lawyer who contacts your client or a Star Representative  that wished to make an interview to one of 
his show business stars . Or multiple situations where we can obtain an exclusive communication.
If we add the fact that these exclusive phones of the show business stars are only attended when they are called from a known
telephone, then we can realize the remarkable power of D612 technology


Do you know what is Bluetooth? 


Bluetooth is a wireless link that modern phones have in order to be linked with "hands-free" accessories. Bluetooth is an international standard that replaces the annoying cables and connectors that were previously employed.
 It has a range of 10 meters. The audio quality is far superior to the wired connection because the Bluetooth link is DIGITAL and eliminates the distortion of the cellphone internal codecs. 

Solidyne was pioneer at the Bluetooth technology link in their portable consoles and telephone hybrids . Select from your cell phone the Solidyne equipment you want to connect and you will manage your calls without touching the phone.

The processor 562dsp Evolution is the top-of-the- line of the famous Solidyne line of audio processors. We have applied in this unit our 40 years of experience developing audio processors for broadcasting, because we are the company with more experience in the field of the investigation and development of new technologies in processing. The 562 is 100% digital, equipped with several DSP units (Digital Signal Processor) that have a total power of 3.200 MIPS (million calculations per second). But, which is more important, the 562 uses DSP of fourth generation, that eliminates the rough digital sound and annoying artifacts, characteristic of the digital processors of the present market. The unit uses converters of 24 bits @ 192 KHz and the processing is made at48 bits, to eliminate the "truncate error" that the audiophiles do not wish to listen... We recommend you to listen our Sound Demonstration (Menu at left). You will verify that the 562dsp is the only FM processor that offers the crisp sound of the digital technology, bringing deep bass and high stereo definition, characteristics of the sound of hi-end Audiophile Audio Systems.

The Solidyne 562dsp is the world only digital processor that brings your radio the audio quality of hi-end units for audiophilesίw with the 3D surround sound of SRS WOW

Why the 562dsp surpasses the limits that processor much more expensive could not cross? In the first place, because before the 562 we have designed other 18 processors throughout 40 years... we had time to learn. We had the patience to wait for the fourth generation of DSP. We had the possibility of applying calculation algorithms that we had perfected during long time and which represent the way in which the ear interprets (through 30,000 nervous fibers) the subtle sound qualities of the real sound. In addition, we deeply understand the limitations of technology DSP to handle fast growing truncated signals (for example those that take place during microseconds, when clipping a signal to increase their energy). All our competitors know the problem, but failed to find a solution. Unlike them, we chose to leave conventional DSP technology, using in its place a new system of 4 channels with 10 MHz of bandwidth (is equivalent to 32 bits with 20 Mega samples) that produces absolutely clean sound, free of aliasing spurious. Only Solidyne 562 can offer this advanced technology to the FM radio stations.

The stereo coder of the 562 DSP also was object of a new vision, different from the used by other great brands. In order to obtain those specifications, that will astonish your Radio engineers, and your own ears, we have chosen to create a new technology doing oversampling at 608 Khz, that allows us to send very high the overtones of the MPX process, being able to set the cutoff filters to 320 KHz (instead of conventional 53 KHz). It manages a perfect phase response with 75 dB channel separation and distortion below 0.003 %, free of alias and spurious components.
The 562 DSP has option for digital inputs and outputs (AES3). Also have MPX output and simultaneous analog balanced output for Internet streaming.

RDS generator is also an optional feature

Another facility that you will not find in any other processor is the MIC Start input. It allows that, whenever the microphones are opened, the 562 changes to a special processing program that allows obtaining the perfect processing for the voice of your speakers. At the same time, the RS232 / USB interface from PC, allows the air automation software controlling the 562 in order to change to one of the 30 stored programs that best fit the musical style. The best processing setting for Jazz is not the same that for Rock & Pop or promotional Ads..

An optional Ethernet input allows controlling the 562dsp from any point of your LAN network or directly connected to Internet
