The small interface is supplied with two cables: one for connection to the iPad (or other iOS device), and the other for connection to a Mac. Although the cables are relatively short, they do free the Jam from needing to connect directly to the iPad, something that would put unnecessary strain on the socket and the Jam itself. Each of the cables locks securely into its respective socket, too, keeping it secure when you're playing. The unit itself is very light, with a plastic body, and has a small plastic thumb-wheel on the side to control input gain. There's also a three-state LED indicator, a quarter-inch jack socket and a USB output socket. On the inside, the analogue to digital conversion circuitry operates at 44.1kHz, 24-bit. As far as connection is concerned, there are some pros and cons to consider. In the favour of the Jam is the fact that the cables are detachable, so if one of them breaks, you won't need to replace the unit, unlike the competing iRig or Peavey AmpKit Link. On the other hand, if you forget the cable for your Jam at a gig, you're stuck. It's good that the jack socket itself has a solid feel that compares favourably with competitors. The LED is useful in that it has three colours: blue means that the Jam is connected but not active, green means connected and active, and red means that the signal level has overloaded the input. Usefully, the green LED also gets brighter when a higher signal level is present.
