There are several ways you can go about connecting multiple devices to one set of speakers. The most practical solution is to purchase speakers with multiple inputs. However, there are several other solutions you can explore to connect multiple devices to one set of speakers. Before you begin, you 'll want to carefully explore your budgetary restraints. In some cases, it may be more feasible to simply purchase an additional set of speakers than go through the trouble of connecting multiple devices to one set of speakers.
If you need multiple devices to access one set of speakers at the same time, you'll need to purchase an audio mixer or audio receiver.
Set-up your audio mixer according to the manufacturer's instructions.
Connect your multiple input devices to the input channels labelled "Input 1" and "Input 2" of the audio mixer.
Connect your speakers to the output channel of the audio mixer.
Mix volume levels equally if you intend the devices to be at the same audio level. Alternatively, mix them to whatever level you deem appropriate.
If you need multiple devices connected to the same set of speakers but you can live with using the devices separately, purchase an audio switch box, also known as an audio/video selector switch.
Set-up your audio switch box according to the manufacturer's instructions.
Connect your multiple input devices to the requisite channels on the audio switch box.
Connect your speakers to the output channel on the audio switch box.
Select the desired device on the switch box.
Make sure to purchase all of the audio cables you'll need for the piece of equipment you decide to purchase. If you're using an audio/video selector switch which has open spots for yellow video cables, you can simply leave those video jacks unused for this procedure.
If you try using a "Y" cable to add multiple devices to one set of speakers you might damage equipment. Although this solution may work, it can send undesired feedback to your input devices and cause permanent damage.
