BEHRINGER/Digital Processor/ULTRA-DYNE PRO /DSP9024


 

Well, it reports on standard Compressor limiter DSP9024 that a lot of mini FM station uses this time.

"Super-low price" BEHRINGER is given though it is a multi band digital Compressor limiter.
is digital though might be a thing. "Super-low price"

No sound of BEHRINGER even if it becomes digital. There is not but no retreat compared with the sound of analog BEHRINGER the difference feeling. Because the processing speed is fast, it is not anxious in a foolish ear that the delay of the sound is accustomed to digital.

There is not a thing that the sound of an extreme setting collapses like the example . either. BEHRINGER might be a cause in the person who likes equipment that are extremely transfigured of the sound that cannot come to like it though this is a thing with a terrible truth.

Taking time in the experience having to the place where taking turning is bad in a common place to the digital device whole of each manufacturer for the setting. Only calling it now memory. Even BEHRINGER whether manage will.
 

 
 
 

This performance seems not to be mastered effectively a regrettable thing though everyone might put out its hand because it is a handy price.

Time hangs even in a professional sound creator who has the exclusive knowledge and the ear to master six Band multi enough. if the band increases, the combination of the setting indeed becomes variegated, and recommends the thing brought close to the sound concept that exists in my head reproducing all the music sources and repeating attention many times.
 

Even if the image and the sound concept of the sound leave vaguely by when, the faced sound is not emitted from DSP9024.

Do you want to emit the sound of what sound concept first of all, what do you want to express as a sound, and the had thing of the image to my sound.

it is important to deepen the image to a necessary sound.
 
 


Then, I will see contents as usual.

One base is exhausted to the vicinity of the back panel in the sky and it has adhered when beginning more than the half. The power transformer is seen a heat sink and a right panel for the heat radiation of the power supply part right. (upper part of photograph)
 

it is connected with the switch and each liquid crystal panel by front panel flat cable of the gray.
 
 

When it begins and the base is seen well it is printed on BEHRINGER ULTRA-CURVE/ULTRA-DYNE MODEL DSP8024/DSP9024 and the base.

DSP9024 was originally DSP8024.
What is different?、it transforms to DSP8024 and DSP9024 by the program that controls DSP.
it seems that the younger brother of DSP9024 because it has been developed DSP8024 of ULTRA- CURVE is years how many ago.

DSP9024 might be a thing from the knowhow of the DSP control obtained when DSP8024 is developed after the birth.

 
 
 

As for DSP9024, reduction in costs is done in all respects.
 
 

it is possible to laugh in the power transformer that doesn't suit about the audiovisual apparatus.

There is no thing that the sound improves even if what code is used in this power transformer though the thing that the sound improves has been described when such a place changes the power supply code into high-level goods for audio on the homepage of the reduction in costs of DSP9024 how many shadow it. To make sure.
 

Such strapping case crowd disregard..base manage make desirous However, because it is this case, the low price shall not be made thing of achievement. The inside of DSP9024 doesn't include VR for fine-tuning analog AMP part etc. at all, and the digital-to-analog conversion will be an internal processing of A/D to thing directly to soon. the signal it persists in reduction in costs.
 
 

 

it is enough also in a poor power supply because there is little part that functions in the analogue.
The place where the sound of BEHRINGER is heard is neatly BEHRINGER.
 
 
 


 
 

The put software program rules a basic control of DSP9024 this ROM. MPU is INTEL . intel is entering.
 

This is installed by two 24 bit high-speed signal processor (DSP) systems of sales. Made in Japan why
 
 
 
The function of DSP9024 can evolve to the functionality of hardness such as twin DSP in 24 bits further depending on software because it is enough though the version of the program at the time of this is 1.3.
 
 
 


it is glad that there are equipment of BEHRINGER inputting and outputting two systems (the horn and Canon inc.), and all the I/O of the horn and the MIDI system is integrated only by using the sub base for Canon inc. by the main base and is done reduction in costs.
 

Because AES/EBU of digital I/O is an option, the terminal of Canon inc. is closed.

contents!?? in not but retreat a though the face and the performance correspond.

it can be understood to say that DSP9024 is a typical product of the low price and high performance that can be achieved because of digital when this photograph is seen.!
 


This DSP9024 that uses a lot of mini FM station it is mastering processor of high performance and high performance, and knows and is ?.
Even if the former steps of the transmitter are equipped, it corks it to our regret straight the function stripes for FM Broadcast. The occupation band diffuses according to the setting and there is a harmed thing,
DSP9024 is no processor for Broadcast.

To make DSP9024 function as Broadcast processor for the frequency modulation broadcasting, the processing such as the emphasis loop backs and the emphasis amplifiers is needed.

As for the audio signal of the frequency modulation broadcasting, Pre-emphasis is processed. (it is 50μS in Japan. )The upper register is raised, transmitted on the broadcasting side (transmitter), the upper register is lowered in reception side FM (receiver) tuner, and it reproduces. As a result, S/N (compared with signal vs. noise) is improved.

Because the modulation band increases if the sound with a lot of upper registers is emitted because the upper register is raised on the broadcasting side (transmitter) and it transmits, it becomes an overmodulation if it doesn't lower the volume and the sound is distorted on the reception side. The BROADCAST processor for the frequency modulation broadcasting controls a needless upper register by operating this emphasis and is improving a usual voice compared with drawing out S/N to its maximum.

Therefore, there is a necessity for making it send DSP9024 the audio signal to which the emphasis is processed and process.

1.it becomes a basic Broadcast specification because of the composition of mixer to Pre-emphasis amp to DSP9024 to de-emphasis amp to transmitter.

A usual FM transmitter processes Pre-emphasis in the modulation machine.

2.Mixer to Pre-emphasis amp to DSP9024 to transmitter(emphasis processing release)
3.Mixer to DSP9024 to (END-EQ Pre-emphasis characteristic setting) transmitter (emphasis processing release)

if Pre-emphasis of the modulation machine (inside of the transmitter) can be removed, the method of "2" might be good in the point of the frequency response.

When the above-mentioned can be composed, let's set the modulation. The level of the transmitter is adjusted to the point that the limiter of DSP9024 is effective in several Band width of 150KHz (100% modulation) in becoming it this side.

it is sure to bring it close to the condition of major FM station in this a little.

Does the setting of the boast of DSP9024 that a lot of mini FM station makes public ahead of that notice and has your bureau strangely noticed a certain thing though the device is necessary to use DSP9024 as mentioned above as FM Broadcast processor?

Let's learn the base of FM Broadcast and draw out a good sound from DSP9024.
 
 
 
 

it is the world of electronics where the thing that cannot be achieved can be achieved tomorrow today.
to a familiar person and the Future..This is broadcast.
