Stereo 1/8" TRS to Mono 1/4" TS adaptor cable. If you have to connect your iPad/iPhone to a guitar amp that has only one guitar input, relax, it's not the end of the world. Some modern guitar amps have this as a standard feature and will happily accept the headphone signal from any consumer electronics. 2) Plug line out or headphone output into AUX In socket in a guitar amp. Similarly, because of the impedance bridging principle, a headphone output can generally drive a line input but a line output generally can not drive a set of headphones.īefore you call for help, check if your guitar amp has "Aux In" (usually one socket in 1/8"). It is not okay to plug a high impedance device into a low impedance device.Įxamples of this principle can be found in guitar equipment: 1) Plug the instrument into effects pedal socket, but from then the signal is at line level through several pedals and the line level finally going into the high impedance instrument level amp socket. Because of the impedance bridging principle, it is okay to plug a low impedance device into a high impedance device.Turn the volume down low and you will probably be okay. If you go the other way around, you will get clipping at high volumes.If you try to plug a device with a low signal level into a device designed to take a high signal level, you will need to turn up the amplifier volume, introducing noise.However, if you want to plug into a guitar amp, things get a little more complicated: However, as we mentioned above, the analog interface is only compatible with pre-iPhone 7 models.Ģ) Lightning interfaces with single guitar input (NOT for iPhone 7 and later models)Īs long as you have an iOS device with a headphone output, you can use "input-only" interfaces and let headphone output take the duty of monitoring. The easiest way to get your favorite guitar sounds from your iOS device.

Let's take a look at what you need to use Positive Grid's apps.ġ) Analog interfaces with headphone interconnect cable (NOT for iPhone 7 and later models) Some interfaces are analog, such as IK Multimedia's iRig 2, and won't be able to work with iPhone 7 and all models after due to the lack of a headphone jack. There are many different interfaces to choose from but most of them are for desktop use, especially those sophisticated ones with multiple in/out, so be sure to choose one that's compatible with iPad / iPhone.
