JAM FAQs
| Q: | Which iOS devices does JAM work with? |
| A: | JAM is compatible with iPad 1, iPad 2, iPhone 4, and iPhone 4S. JAM does not work with iPod touch or iPhone 3G. This was miscommunicated at launch and has since been corrected on our website as well as Apple’s. |
| Q: | Which iPhone apps are compatible with JAM? |
| A: | The below apps have been tested and proved successful using iPhone 4 running iOS version 4.3.5. Apps will be added to this list as they are identified compatible.
*When using these apps, make sure you have headphones connected first. If headphones aren't connected, JAM will not stream properly. |
| Q: | Will JAM work with my computer? |
| A: | JAM requires an Intel based Mac and Mac OS 10.6.4 or later. |
| Q: | What can I connect to JAM? |
| A: | You can connect any instrument with a 1/4” output to JAM for great sounding recordings. Electric guitar, bass, acoustic guitar with pickup, keyboards with a mono output, violin with a pickup etc. Our tests show that low impedance dynamic microphones can work well when you use a line transformer. |
| Q: | Can I connect a microphone? |
| A: | JAM is optimized for electric instruments, like guitar and bass specifically. However, with its 40 dB of input gain, JAM can be used with certain dynamic microphones using an XLR to 1/4” cable or adapter. We have tested both Shure SM57 and SM58 dynamic microphones and each worked well when recording loud sources such as a singer. We recommend you purchase an impedance matching transformer if you choose to use JAM for vocals. Additionally, since JAM is a guitar interface, Phantom Power (48v) is not included. Condenser microphones which require Phantom Power will not work unless they have their own built-in power supply, such as a battery. It should be noted even with a built-in power supply, the amount of gain available is more suited to instruments rather than microphones. |
| Q: | What is a Line-Matching Transformer? |
| A: | A Line-matching Transformer is an adapter with a female XLR connector on one end and a male 1/4” connector on the other. This transformer converts the low-impedance signal of a microphone to high-impedance for connecting to a device like JAM. In this process, the transformer is providing additional gain for optimal signal level. |
| Q: | What is PureDIGITAL? |
| A: | JAM is a studio quality guitar input. Unlike similar products that are simply adapters, JAM is a digital audio interface. It transforms the analog signal of the guitar or bass into a digital signal that can be seen by an iPad, iPhone or Mac. For this delicate transition from analog to digital, Apogee has designed special high quality circuitry that preserves the true tone of the instrument so when you record into software like GarageBand or just jam on your iPad you are hearing the best possible representation of your guitar. We call this, PureDIGITAL. |
| Q: | Can I use JAM on stage? |
| A: | Yes it is possible to use JAM live on stage. To do this, you will need the appropriate adapter to connect the headphone output of the iPad/iPhone to the venueʼs sound system. The most common version of this adapter would be a 1/8” connector on one end (from your iPad/iPhone), and a 1/4” connector on the other (to a mixer/or powered speaker) |
| Q: | Can I connect a the line output of a device to JAM? |
| A: | It is possible to connect a line output to JAM, however the output must be unbalanced. JAMʼs input can be driven up to 14dBu unbalanced and it is recommended that the output device be set to a -10dBv reference output level. If the output level is +4dB referenced, it is recommended to be cautious with the amount of output gain being sent to JAM. (6-10 dB below maximum output level). Examples of line output sources may be, mic preamps, mixing consoles, outboard signal processing equipment, etc. |
| Q: | Who should update firmware? |
| A: | This firmware update is intended for JAM users who require 48 kHz sampling rate functionality or are experiencing connection issues on an iPad 2 after updating to iOS 5. |
| Q: | My JAM is not recognized by my iPad 2 with iOS 5, what’s wrong? |
| A: | On an iPad 2 updated to iOS 5 and above, connecting or disconnecting headphones while Jam is streaming to an audio app causes Jam to become unrecognized by the iPad, and Jamʼs LED turns blue. |
| Q: | JAM doesn’t work when using Apple earbuds (with mic), why? |
| A: | iOS devices accept audio input from the most recently connected peripheral, in this case the mic built-in to the headphones. To re-establish input, disconnect and re-connect JAM. |
| Q: | Can I play along with my music on iPad/iPhone? |
| A: | To play along through JAM with your music on iPad/iPhone, you’ll need to have the latest versions of GarageBand and iOS software installed. Select the desired song and begin playback BEFORE opening GarageBand. |
