Well, this equipment dismantlement series dismantles the consumer machine of SONY.

These 11 series can be able to be finished up in the small space design by the EIA-1U rack mount type made for the business such as broadcasting stations.

The only good one is good though the equipment made of SONY is hated, and it is a thing however like Cost Performance and natural convenience, etc.
why to have adopted this model in me basically because I have encountered painful in respect in the past that is variously.
I do not have the prejudice, and if this report is seen, does the thing of the hated manufacturer understand by me and if it is acceptable, understand the reason why the SONY product is hated a little though adopts?
 

CDP-D11 CD Preyar(up) MDS-E11 MD recorder(under)

When the sound was heard natural in the public welfare machine that SONY did because it was not if adhering to an essential sound first, the impression of the sound of the broadcasting equipment of old DENON was received. An inside region with putting doesn't feel SONY and the sound firmly done is. My favorite sound is emitted sound. Is the chosen maximum reason a space factor of sound and 1U?
 
 
 

SONY /CDP-D11

Then, let's pursue the subject while seeing contents as usual. Anxiously though it will become an equipment dismantlement page what time it is.

Then, it is CDP-D11 of CD Preyar first.

The front panel : made of aluminum of the gray painting. The switch and each liquid crystal part is arranged extremely simply.

Because the CD drive is a type to make CD no tray type it, and slide into straight, an extremely smooth putting in and out can be done. There is no useless operation said that the tray is opened, CD put, and it closes. It is can a quick exchange of CD in the program, too and a suitable drive for coming program.
 
 
 
 

All cases consist of SPC Hagane excluding the front panel. It doesn't "Henahena" it because there is board thickness though it is a thin case with 1U even to things except beginning. Let's assume it is good because seem made of SONY around here and it doesn't exist.
 

When beginning, it lays it out in the left of the front, and the power transformer is laid out in the drive unit and the interior and the substrate is laid out to the interior. The control systems of RS232C and the parallel control circuit, etc. and the output systems such as a power supply circuits and analog amplifiers are developing with this substrate. The basic circuit of digital audio is under the drive unit and doesn't exist in the seen part.		Then, I will see from the power supply. It is a usual power transformer in the thin core installed on the case with 1U, and as for the leakage of the flux of magnetic induction, it is large and the influence is causing it extreme to other equipment though the belt of copper has been rolled. It is Rainfitar substrate on the AC side, and is a power supply circuit and a forward line OUTPUT circuit in the right of the transformer. The power supply is +/-15V, -9V, and 5V for a digital circuit for OP-AMP.

 
 

Canon connector (XLR-3) has adhered by the balance output because the line output is two systems, and business uses of -10 the dB of +4dB and the public welfare standards. The power supply circuit of �}15V is used only for this output circuit.		Digital OUTPUT has coaxial (IEC-958) and usual optical connector output. Substrate interior parallel control circuit and coaxial OUT are 5V power supply circuits in the left of this side from which the pulse transformer is used and insulated for logic.

 
 
 
 
 

		Control system circuit part that leads to CTRL-S, parallel control, and terminal RS232C It is a design of the layout. considerable rough

 

 

The operation logic substrate is covered with the shield that can be done with the front panel and SPC Hagane of aluminum. In the operation logic system, will it already be a natural technology that an analog circuit and an enough distance are taken to prevent a digital noise that occurs from MPU and the liquid crystal display circuit, etc. and the shield is given more strictly? It differs obviously from the design of rough layout the large substrate that develops in the case.

 
 

 

 
 

The back panel can differ from simplicity in the reception desk and be controlled variegated and remotely. Control system, RS232C, RELAY PLAY, parallel control, CTRL-S,
digital person in charge of voice OUT PUT, coaxial (IEC-958), analogue digital (EIA CP-340) person in charge (Consumer Specification -10dB) optical, and standard output +4dB from the left(XLR-3)

Because it is possible to control without parallel controlling, and peeling off and using an external equipment of special, the range of the application is wide and convenient.
 
 
 
 
 
 
 
 

SONY /MDS-E11
 
 

I think here to be sold previously though it is MD recorder MDS-E11 of the same design as CDP-D11 of CD Preyar.

 

 

It is a drive unit in the left of the front when beginning. They are the output systems such as a power supply circuits and analog amplifiers of the amplifier in the substrate in the power transformer and the interior. the interior The control systems of RS232C and the parallel control circuit, etc. are laid out to the substrate in a right interior. It doesn't see it because the basic circuit of digital audio is as much as CDP under the drive unit. Something rough-and-ready work nature does considerably by about design compared with CDP-D11.		Notorious power transformer that scatters inducement magnetic field The same thing as CDP-D11 is used. If a "Troy dal transformer" of an analogue system amplifier of BEHRINGER is used, there is not an inducement magnetic field where it influences other equipment and either might be the thing in a clean equipment that has finished. Was it severe in the cost?! It is a power supply circuit and line OUTPUT circuit in the line filter substrate interior of the AC side. right of the transformer The power supply is +/- 15V and 5V for a digital circuit for OP-AMP.

 
 

 

Different balance input, output circuit, and the power supply circuit separate to one substrate and it is made with the part OUTPUT of CDP-D11. The sound emitted naturally is also the same because the output circuit is the same circuit as CDP-D11, and the connector of (XLR-3) has adhered by the input output attendant balance because it is a business use.		The inducement magnetic field of the substrate of the I/O circuit of the power transformer. To receive the influence directly, the shield board is partitioned. From the beginning to wanted transformer by me than putting up shield board of tinplate in such a place by any means

 
 
 

 

It is a toy of tinplate like the MD drive unit and the example, etc. When they are other manufacturers, it : around here. Do though it is thought that it makes it from the die cast frame or something?The place said so cannot be yet understood. There is basic circuit board of digital audio of the control circuit and the recovery circuit, etc. under this unit.		It is 5V power supply circuit in the center of the photograph for logic. It was in the left of this side and did not exist in CDP-D11. The memory backup battery is seen.

 
 

 

Control system circuit part that leads to CTRL-S, parallel control, and terminal RS232C From CDP-D11 to design of rough layout The terminal RS232C part is not integrated in the main substrate and is another substrate why.

Substrate casual draw around wiring ribbon cable substrate useless space take put substrate something rough-and-ready work think.

I can obviously hear the difference of the manufacturer to the product by comparing it to contents of the BEHRINGER product regardless of analog digital.
 
 
 
 

Place where the world is obviously different from doubtful design that develops with other parts
 

Only here is firmly designed as well as CDP-D11. The operation logic substrate is covered with the shield that can be done with the front panel and SPC Hagane of aluminum.

Because the liquid crystal panel output the noise, it might already be a natural technology, and control part and liquid crystal panel part DSP9024 of BEHRINGER had been completely shielded in this kind of equipment.
 
 

 
 

The back panel can differ from simplicity in the reception desk and be controlled variegated and remotely. Analogue person in charge of voice IN and OUT PUT (Consumer Specification -10dB), digital person in charge and coaxial (IEC-958) control systems, CTRL-S, parallel control, RELAY PLAY, RS232C voice IN, analogue person in charge of OUT PUT, and Standard I/O +4dB from the left(XLR-3)

There is neither RELAY PLAY nor a peel only by the reproduction and the recording is also possible.
Digital I/O is coaxial alone and doesn't have a usual optical connector output. Because it is possible to control without similar CDP-D11 parallel controlling, and peeling off and using an external equipment of special, the range of the application is wide and convenient.

MDS-E11 RS232C INTERFACE MANUAL

 
 
 
 

I had been surprised at the difference of mechanism before. Made of SONY, the frame of mechanism was well-made, and Panasonic and made by Aiwa, it was stoutly made from the frame by the die cast, and the frame of Aiwa was especially

well-made for piercing SPC Hagane like the example. The mechanism frame of SONY ..holding considerably for a long time.. is skillful in piercing Hagane. SONY has a short life though it is thought that the strength and the correspondence years change in the case. When the movement is repeated by the fieldwork etc. , an initial performance of mechanism is suddenly lost though it is not and cannot know the great difference to put quietly and to use it. !!
Therefore, I hate SONY. !!
