Amp help

ok hi! Im new here, and I need some help. I am currently building an amplifier out of the parts of an old creative SBS 4.1 . I have found the datasheet for the philips TDA a85j ic, and have dowloaded a schematic for it so I can build an amp with it. I would like to make it a full range amp instead of having the bass frequencys cut off so as not to damage the sats, I want to power some other speakers with this amp. My question is about the amp ic that powers the sub. Its labled CREATIVE CT975-SAM , and so far as I know, Creative does not manufacture semiconductors. Any help on finding a datasheet on this ic, and possibly a n application diagram? any help from anyone, or from creative techies would be greatly appreciated. I also need help with another system I have. Thanks,
~Roadrunner~

Thank you for the help lacy ,
I'm having the same problem with a single stage amp. If you fell like looking at it I've attached a picture and the sim file.

Op-amp help for a newbe

Hello all,
I'm new to Workbench so I like to start by saying, thank for any and all help.
When I used the stranded scope the input sin was the same as the output sine in voltage, but when I tried the Tektronixi scope and put in 1 mv the output was 3.1 volts dc. Could someone tell what may be going. on.
Best regards,
Ken
P.S. I would like to get an output of 40 khz square @ 5v

ABAP and Java mapping

Wanted to confirm my understaing for ABAP and JAVA mapping.
Am I correct in my assumption that these mapping techniques can be used only if input and ouput is in XML format ?
So if XI is receiving a flat comma separated text/non-XML file or an IDOC for that matter and output is NOT in XML format, say again flat text file or IDOC, I cannot use above two techniques?
All the docs I have read suggest that 'Execute' method is called when XML file/data is received, paresed using DOM/SAX/JAXB (for Java mapping) or IXML lib (for ABAP mapping) and then create a output XML file.
-Thanks in advance

Hi Bob,
Here you have a code sample for deescaping. I have have written this code a couple of time ago. The incoming file can be any text format. It might be XML, but not necessarily.
The main method is not reqired, but good for testing.
Regards
Stefan

HT204368 I have an IPhone 5 & Bluetooth just keeps searching & doesn't connect to devices I'm trying to pair with. Says "not supported"

Sorry, if I've posted in the incorrect place. First post, please bare with me.
I've been trying to transfer photos from my old Samsung Galaxy Ace & Toshiba laptop via Bluetooth to my iPhone 5.
iPhone but message of "not supported" comes up when pairing. iPhone stays in search mode when trying to discover devices & does nothing.
Thanking you all in advance for your patience, understanding & help.

All you can connect via BT are headsets and keyboards. You cannot connect to your Galaxy or laptop. That's why it says "not supported."

Jspx template migration to jsf 2 problematic

Hello experts,
I have a ADF web application developed with JDeveloper 11.1.1.4 using JSF 1.2 deployed on WebLogic server 10.3.4.
When I migrate to the new version jsf 2: Build JDEVADF_11.1.2.2.0_GENERIC_120418.2212.6183.1 and WebLogic server 10.3.5, the jspx template below misbehaves.
The menu is brought from the left to the right hand side, though it expands and navigates well, the page contents, but the menu and logo, are not displayed.
In other words, I can only see the logo, the moved but working menu but nothing else.
Is there any way of correcting that kind of behaviour and migrate the app?
Thank you in advance!

Popup Command Button - ActionListener not accessed

Hi there, I'm working with the JDeveloper 11.1.1.6.0.
I have a view in a popup. Which creates a new empty row, if there could not be found any data in the database. So far so good.
When i know enter some values and then click a command button the values should be filled into the VO and EO, and also commited to the DB.
I have to do that in a ActionListener, beacuse i have to set some value programmatically, because they come from the calling page, and could not be seen by the user.
So, when i now click the button, the popup dissapears, but the ActionListener was not entered. I tried it via breacking points and debuging and via some Outputs, but neither they are reached. Do I have to make something more to reach the listener to perform my actions?
Thanks in advance.
Alex.

Transferring Data From MacBook To iMac

I'm not exactly sure what category to file my question under due to it's unique circumstances, so I tagged & selected areas & categories that I thought were appropriate to widen the range of people who will see it & hopefully, make it more likely that I'll find the answer I'm looking for.
I was given an older iMac computer by a family friend, it's old enough to not have an iSight camera built into it, but new enough to have well-working wifi & Bluetooth connectivity available on it & support it's updated software without posing any problems. I believe from what I can gather & the looks of it, it's currently running Snow Leopard, but I can't be completely sure because the newer software was installed previously, before I received the computer, although I'm pretty sure that it is Snow Leopard.
I also have a MacBook that stopped taking a charge long before I got the new (to me) iMac, the repair is not worth the cost, so I would like to transfer the data from my MacBook (irreplacable pictures, music, etc.) to the iMac, I'm planning on purchasing an external hard drive & an external battery charger, but I can't afford it at the moment & would like to transfer the data as soon as possible, so that I can access it all again, but there's only so much battery life left on my MacBook battery right now, about 10% at the very most, which is certainly not enough to keep the computer on long enough to transfer it all with file sharing via wifi/Bluetooth.
So, I was wondering if I could possibly connect the two through a USB cord & transfer it without the MacBook being turned on or if there was any other way to transfer information without having to turn on the MacBook to do so?
My MacBook has a unibody & was purchased brand new in about mid-2010, it was either the last or at least, one of the last models of MacBooks made before MacBooks were discontinued, & it also runs Snow Leopard. I could never figured out how to work Time Machine & from what I could figure out from the program it either cost money to use/I didn't have any external place to store a large amount of data, so no, I don't have a working Time Machine because I never could set it up. I don't what might have relevance to my situation or not so, I tried to give as much information as possible in case it could be helpful.
Thank you all so much for your time, input, & help, I really appreciate it! (:

You could pull the hard drive out of your MacBook and put it in an external case.
Here are video instructions on replacing the hard drive on the White Unibody http://eshop.macsales.com/installvideos/macbook_13_09_unibody_hd/
Here's a cheap SATA external hard drive case on Amazon http://www.amazon.com/Vantec-NexStar-2-5-Inch-External-Enclosure/dp/B002JQNXZC/r ef=pd_cp_pc_0
If you don’t have the tools to open up the MacBook OWC has a set for $5

IPad 2's Back

What is iPad 2's Back made of?
Stainless steel? (:O!)
Aluminum?
Or what?
Will it rust/corrode easily?
Like if I got sweaty palms and took it out of the cover and sweat got on it..
If it does, how to stop it from rusting further?
Apply powder to absorb the water?
Thanks in advance for your replies & help!

Certainly not SS. Probably aluminum.
Don't worry about it. Just don't dunk it in the bathtub!

HT1222 iOS 6 update now iTouch

Updating iTouch to iOS 6 and it froze my iTouch mid-update and now my iTouch has a blank screen and is not recognized when I plug it in to my computer.

Obviously I have no idea what I am doing. So I went to the settings & the mail account like you said. My yahoo account info was never put in there. iCloud was the only account that was there. I have been going to my email through the yahoo app. So I added my account & it didn't seem like it worked but then after a few minutes all my emails started coming through the email app. So I still can't sign in to my yahoo account through the yahoo app or safari but I am now getting my emails through the email app. So THANK YOU for being patient & helping me out! Thank u thank u thank u! I really appreciate it!

Audigy 2 ZS clicks when record

Hello everyone.
I could use a little help. A while ago, I built a system, and included the Audigy 2 ZS. I only have just gotten around to trying to record with it, up until now it has all been play back.
So once I got everything working satisfactory, I noticed a clicking and/or popping sound present only in the recorded sound. Trying to fix this, I updated my drivers, and maximised my audio buffer. Now the clicking has improved, about 50%, but it is still there.
I did read the FAQ about the distortion in play back, but I assumed that because this is recording and not play back, that maybe the solution would be different. All apologies if I was wrong.
I'm using Cakewalk Home Studio 2002 to do my recording.
Can anyone offer any help? Thank you.

*Bump*
Can anyone offer any assistance? Would pre-amping help at all? Is it just the chipset, or is there something I can do about this?

How can I boost the volume so I can hear a movie on a plane

I cannot hear movies while I am on a plane using MacBook Pro or my ipad. I have tried using the apple ear buds and sony noise cancelling headset. Will a headphone amp help?

I actually bought an App in the Mac App Store called Boom (sorry, I don't name these things). It was well reviewed, and it really boosts the sound out of my MacBook Pro. I can actually watch a movie listening to it through the MBP speakers.
It doesn't use up much RAM, and it really works. And no, I don't get a kickback for recommending it, but I can tell you it's changed my viewing and listening experience with the MBP.
A headphone amp also works, but it's just more junk to carry.

Help on either using a DI Box or a Pre Amp?

I recently bought an iMac 3.06 and I was wondering whether i should use a DI Box or a Pre Amp to connect my bass guitar through the Mac. I have no idea what I am doing any help would be great!
Thanks Nick

Hi Nick
Welcome to Apple Support Communities
Actually there are a couple of inexpensive little gadgets that will allow you to connect your guitar to the iMac.
An [MXL iBooster Guitar|http://pro-audio.musiciansfriend.com/product/MXL-iBooster-Guitar-and-Mic rophone-Interface?sku=243800] to the 3.5mm Input Jack.
Or a [Griffin iMac|http://www.griffintechnology.com/products/imic> to a USB port.
