USB & Firewire audio interface ports still work as input and output?

I guess everyone has to start somewhere, even if it is borne by almost everyone I would like to know the answer to my questions, perhaps with good reason, what I don't know is so if the USB ports unique connection and firewire on an audio interface function ALWAYS both as input AND output.  In other words, whenever I read the information about the product on audio interfaces, no matter where I go, it is generally accepted that most people buy their audio interface for RECORDING.  And so when most people talk about connecting their Apple computer, iMac or MacBook Pro, it is generally accepted, they turn to the USB as INPUT.  That's all very well and good.  But in my case, I want to use the USB port as output (not the taken mini) and go into an audio interface that gives me as a symmetric output signal that I can plug my amplified studio monitor (which has only a balanced XLR input). All of the examples I see with audio interfaces address registration and involve the use of the USB on the audio input interface.

So my question is: can one USB port I see on any number of audio interfaces always function both of the inputs and outputs? It takes, but if so, why does any site mention this fact and whey didn't they show in all the diagrams of the audio interface manual hook to studio monitors?  I know what may be obvious to some, but as a user with the intention not to use a piano for a scene while but rather a keyboard/MIDI controller that is attached to the iMac to be able to use the virtual instrument software, I need to go to the controller to the iMac, then the iMac in symmetrical powered monitors. Do the balanced inputs of speakers requires more than a simple adapter to give the President a balanced input.  But nobody talks about audio interfaces usually unless they talk about as a way into the computer to record.  As for my situation? Why don't they include this example?  And why should they assume that novice will automatically KNOW that the usb port, an audio interface will work as an output as if they never EVER mention this example or Setup?  I guess it is to operate in both directions!  But really, I'm crazy to wonder when no one never speaks or shows this configuration? He suggested I buy something similar to a UR22MkII of Steinberg, who has a USB port. Even the Steinberg site speaks only records and so using the USB key as input for use with the recording software. There is no mention of its use out the mac in balanced speaker entries, even in the manual. In fact, it is question is always true for every audio interface manual that I watched, even by other manufacturers! Why they all assume a novice like me (whose money is just as good as money from the experienced user) KNOW that? It's frustrating!

I know that this is not strictly a matter of logic, but I guess, in my view correctly, that a logic user community could be more appropriate to address my question for others communities. If I'm wrong, please help to re-send-the matter.  Thank you.

Sound the interface itself that determines it can send and receive Audio or Midi... not the USB or FW port which both are devices of e/s...

All USB and Midi peripheral FW are inputs and outputs

All the USB and Audio FW are inputs and outputs...

All devices USB or external hardware with a USB port... can handle Midi and Audio...  Some do... Most manipulate just Midi... or just Audio

The Steinberg UR22MkII manages Audio and Midi...

However, I do not recommend USB 2.0 audio devices... There are simply too many cases, problems and questions after the major updates for OS X with such devices especially when they are class compliant (IE without driver), even if the UR22MkII Steinberg is supposed to be compatible 10.11...

View the other may vary... because it's just a personal opinion based on my past experiences both in my studio... and based on the many issues presented here and elsewhere.

I'm sticking with Motu equipment for all my Audio devices... and I use iConnect devices for my Midi needs...

  • Why not USB-6509 allow setting input and output on individual ports?

    I have one of the new USB-6509 (96 digital i/o channels) commissions.  It has 12 ports for every 8 bits.  The manual says that you can define the inputs and outputs on a per port basis.  When I read an 8-bit port that I find it clears different ports that I put in place to be digital output.  They seem to be grouped into 3 groups of 4.  0-3, 4-7 and 8-11.  When I read from any single port within this group it erases the other ports in this group that I try to use as exits.  The result is that I can put only input and outputs in groups of 4 ports.  Unfortunately, we have built custom hardware based on the assumption that we could control the inputs and outputs on a basis of port by port.  I see this problem as well with my LabVIEW 7.1 program (see table), as well as the measurement and Automation Explorer.  Is anyone out there seen this problem with the USB-6509?  Anyone using it with success?  I also notice strange problems with power on, but I have yet to understand the model.  IM wondering if I have a defective material or maybe this new material still has problems.  I tried NIDAQ 8.7.1 and 8.8.  Same problem with both. Thank you.

    Thanks for the replies.  It was determined that the USB-6509 we have has a hardware malfunction that is causing the ports to interfere between them.  We are return to OR for repair or replacement.  For now, we used a PCI-DIO-96, which works correctly. Thank you, Andy

  • synchronize the inputs and outputs on the USB-4431

    Hello

    I have an application that needs to send a signal on the USB-4431 and then capture it with an entry on the same device.

    Aware that I use two tasks to do this, one for input and one for output. I discovered that a trigger (on the RTSI bus) can cycles of sending/capture sychronisé departure operations so that it can be a constant offset between the captured signal and the output signal.

    Unfortunately, the code I found is for Matlab. I can't find an equivalent for it in the C API of NIdaq. The method is described here; http://www.mathworks.in/help/daq/synchronize-analog-input-and-output-using-rtsi.html.

    What I can't understand is how to implement this on the analog input:

    ai.ExternalTriggerDriveLine = 'RTSI0';
    

    Can someone shed light on how to do it?

    The rest of the things described here, seems to be feasible with a normal trigger:

    ao.TriggerType = 'HwDigital';
    ao.HwDigitalTriggerSource = 'RTSI0';
    ao.TriggerCondition = 'PositiveEdge';
    

    Thank you

    Nirvtek

    You can synchronize the HAVE and AO by sharing the start of relaxation between your two tasks.

    Choose one of your tasks as the "master" and the other to be the "slave" (any).

    Set up a trigger to start of digital dashboard on the task of the slave, and set the source of the trigger to be the trigger of the master's departure.

    Assume the following:

    The name of your device is 'Dev1 '.

    I is the main task

    AO is the task of the slave

    Here's what you would do to sync the two:

    (1) create the tasks I and AO in order that you want to

    (2) set up "timing" on the tasks of HAVE it and AO (you choose the sampling rates must be the same or power-of-2 many of the other (for example 100 K, 50 K, 25 K, 12.5 K, etc...))

    (3) configure your slave (the task of AO) task to have a numerical advantage start trigger and make the source is the trigger for the start of the task of the master (the task to HAVE it). In our case, "Dev1, AI, StartTrigger.

    (4) write data (a sine wave, presumably) to your task AO

    (5) start the task from the slave (the task of AO).  The task of the AO is now in the 'Started' State, but given that you've set up a digital trigger early, it won't actually generate data until he sees a numerical advantage of 'Dev1, AI, StartTrigger.

    (6) to start the main task (task to HAVE it).  The task of the AI does not have a trigger digital early, so the software will immediately generate a start trigger, which also causes a numerical advantage on "StartTrigger/AI/Dev1", which causes the task AO start at the same time.

    7) read your job to HAVE.

    You will notice a few 0 at the beginning of your data to HAVE. It's a result of something called "Filter Delay" and it is an inherent characteristic of all DSA devices - see the manual to use DSA and this article for more information on what is and how to cope.

    I hope this helps.

    EDIT: I just noticed that you pointed out an existing C example. It's exactly what you want. I don't know why you have a resource error booked - I tried it myself and (after changing the AO will of +/-10V to +/-3 .5V), it works beautifully.  Try to reset your device to the MAX (or DAQmxResetDevice() of your program)

  • Individual access to the inputs and outputs on a single port (PXI-6509

    Hello

    I use PXI-6509 and this sentence taken from the Manual:

    "You can use each of the DIO lines as the input to a digital static (DI) or digital output (DO) line"

    leads me to believe that each individual DIO can be defined as input or output (even within ports), but picture:

    shows that these ports can be defined as inputs and outputs in the same port.

    On another card 6284 with DIO, I can put them individually.

    Can someone confirm that the 6509 is correctly?

  • Problems with the Firewire Audio Interfaces

    I use a Presonus Firebox for all of my recording and playback. I just bought a new pc HP with Vista64 and I had problems with my audio since then. Symptoms include random audio dropouts, crackling sounds when you scroll through the menus in my software, no noise at all from windows media, no windows generally sound player. Everything works sometimes, but inevitably fails. Once the audio is de-energized my only solution is to restart the computer, and then it still doesn't work sometimes. I don't understand. My last computer was a couple of years and built the hand. It worked perfectly with this unit until the motherboard is dead after what I bought my new HP desktop with terrible results. The main difference between my pc and this one is that I was using XP and XP64. However, I have the right drivers for the home and the computer recognizes it but I can't operate consistantly and correctly. This new HP has more power than my last, and more then enough power for my needs recording software. I would like to know, I've been recording music on PC for 8 years. Any advice would be welcome.

    I am now convinced that the long nightmare is finally over. I tested my home over and over again with no failures. Record and playback midi seem to work perfectly. Here's what I did:

    1 optimized my computer for audio streaming using the guide written by sweetwater.com.

    2 uninstall all the drivers from Presonus and all software, including the removal of all PreSonus files on the registry using the instructions provided by the technical support of PreSonus.

    3 disabled WLAN and then physically disconnected from the motherboard.

    4. my computer has two firewire ports. The front port was connected to the motherboard via a short cable. I physically unplugged the cable from the motherboard.

    5. I bought an Express(1x) PCI firewire 400 card with a Texas Instruments chipset. The exact brand is inner Pro PCI Express(1x) 4 port 1394 a. The firewire card is a power port. I plugged the power jack on the same line, connected to the DVD player. I don't know if it's important, but I'll try to document EXACTLY what I did. The firewire card requires no driver work. It came with a disc with a B.S. video editing software I was not installed.

    6. I turned on my computer and disabled the built-in firewire in Device Manager, leaving only the new active firewire card.

    7. I installed the drivers from the Firebox from the original disc supplied with my unit (v1.20.0). I had good results from these pilots in the past that may be because I use XPsp2.

    8. I have connected the combustion chamber when prompted to by the installation software.

    9. rebooted the computer with the combustion chamber connected and everything's fine.

    By the way:

    The inner firewire card cost me $ 30.00

    My computer specs are:
    HP a6745f desktop
    Dual core AMD 5050e 2.6 GHz
    XP sp2
    GigsRAM 4 (3.25 because I'm on XP)

    If you are confused in the store on the question of whether a firewire card uses a Texas Instruments chipset. Try to get a glance at the map. You should see a chip bearing the logo of TI: the State of Texas, w / Ti. YeeeeeeeHawwwww!

  • Impossible to get trunk port to work on 4402 and 6509

    I'm having a problem getting circuits developed on a pair of 4402 I just expdis preconfigured.

    The switches are running Catos.

    I've tried both using a SHIFT and individual ports on the WLC, and the only way I can access the WLC is when the switch port is configured as an access port.

    Whenever I have change the link mode on, I lose access.

    I tried to restart it and that didn't work either.

    The subnet manager and ap - manager is in vlan 254, and I put the vlan native of the switch ports to VLANs 254.

    I tried all forms of the sheath (desirable, nonegotiate etc.), but I just will not work.

    I use this exact set elsewhere without any problems.

    Controller was originally on 4.2.130 and is now on 5.1.150.

    Someone has an idea or two?

    Very well. First make sure that the wlc which management Manager and thus lies on the same vlan. Also, make sure that it is not signposted in the wlc which means that it is set to '0 '. On the trunk dot1q, assign it vlan native what the wlc is configured for. Make sure that you do not have the global command "tag dot1q vlan native. Also male that the service port has an ip address and not routable in your network.

  • Audio samples of input and output rates do not match.

    If I get an error that supposedly get a lot of people, I think I know the problem of fixing, but I think that it is impossible with the microphone that I use but I want to make sure it's just the microphone that I use and nothing else. So I went in "reading devices" and "recording devices" check if they were both on the same sampling frequency, but I could change the sampling frequency of spekers in properties, but not the MIC... the microphone that I use is the PS2 eye cam, it works very well I had to download "CL eye test" to get it running, but it works , by default the format its deadlock is: 4 channels, 16000 Hz (tape recorder).

    The box is grayed out and I have no idea how to do to change the frequency of sampling for it... so now I can't use the program pretty at all to save

    I am sure that you will not be able to change because it is defined by the hardware built into the microphone. If you want to use with the hearing, you should make sure that windows sounds and hearing are configured for 16 k. Otherwise if there is any software that came with that allows you to record must be able to transfer the audio to hearing to change.

    However, Eye Cam is really a toy. If you are seriously in the audio recording, you'd be better off getting a good microphone and audio interface.

  • Realtek HD Audio Manager in Windows 7 turns front input and output Sockets.

    We recently bought a new computer with Windows 7.  The sound Manager, Realtek HD Audio Manager, disables the catch before entry and exit.  It does not actually recognize before struggling when you insert the headphone or microphone (what he does for the rear Sockets).   I tried to reinstall, but the same thing happens. I'm getting desperate.

    Open the Realtek HD audio Manager.

    In the upper right corner is a small folder icon, wriggling over the ToolTip says "the connector settings." Left click it opens a dialog box.

    Issue seems to be in the first line "front jack detection".

    For me, this box is unchecked. It controls restored façade function.

    Seems intuitive combat, but it worked for me.

  • None of my audio jacks do not work. Front and back (office)

    Recently, I connected my desktop computer for an amp with an attachment to a rope to get sounds. It's a beefy amp and I don't have all the sound cards in addition to that on the motherboard. After that I connected and discovered, he did not. No audio jacks working now and I reinstalled Realtek HD Audio Manager twice and no solution. How can I fix this to get the worksheets?

    Hi MitchellCochran,

    1. have you disconnected the amplifier on the computer and still there is no sound on the computer?

    2. you receive a message on the audio device works is not on the computer?

    Method 1

    Check and make sure that the correct audio device is set as default.

    (a) click the Start button and then click Control Panel. In the search box, type sound, and then click sound.

    (b) click on the read tab, and then look for audio devices. These appear as icons of the speaker and are labeled as speaker, track of the names of the devices.

    If you have multiple devices, the default device has a check mark next to it and is labeled as default value.

    (c) if the wrong audio device is listed as default audio device, click the correct audio device, click set as defaultand then click OK.

    Change the audio device may require that restart you your computer.

  • Update iOS 9.2 ceased to iPad Air working with audio interfaces

    ios9.2 was last updated stopped my ipad, being able to work with my a peak interface. Unbearable noise on the two input channels when recording in GarageBand or other audio program.

    no solution of the next Apple or apogee. Grid have released at least a positive tovthe update software (even if it doesn't at least they try)

    I thought the score using such a product locked as an iPad mean everything should work together... how wrong I was.

    All solutions?

    P

    I know how it feels, bro. It happens again and again because Apple focus only on build-in apps without looking professional applications and the needs of professionals. I remember how I had to write to the bracket of Novation, because their audio interface no longer works with versions of Mac OS X. After each update Apple OS, something no longer works and we need to find alternatives to the result. And that is a problem. You can simply downgrade OS X, but you can't do the same thing with iOS.

    You only have the ability to write at peak and wait for the update. Apple support is more useless than Microsoft - it does not at all
