Roland EX is a versatile portable keyboard that allows you to connect your smartphone and other audio devices for expanded functionality. In this guide, we will provide a detailed description of how to connect your smartphone and other external speakers to the Roland EX. Let's begin!

Connecting your smartphone to Roland EX:

1. Ensure that you have a compatible audio cable. You will need a 3.5mm stereo mini-jack to the appropriate cable for your smartphone.

2. Locate the "Audio In" or "Aux In" port on the Roland EX. It is usually labeled with a headphone icon.

3. Insert one end of the audio cable into the headphone jack of your smartphone.

4. Insert the other end of the audio cable into the "Audio In" or "Aux In" port on the Roland EX.

5. Set the Roland EX's volume level to a suitable level.

6. Play audio on your smartphone and adjust its volume accordingly.

Connecting external speakers to Roland EX:

1. Determine the type of external speaker you want to connect. It can be powered speakers, passive speakers, or amplified speakers.

2. If you are using powered speakers, such as studio monitors, ensure they have a compatible audio input and a power source.

3. If you are using passive speakers, you will need an external power amplifier to drive them.

4. If you are using amplified speakers, such as PA speakers, they should have a built-in power amplifier.

5. Connect your external speakers to the Roland EX using appropriate audio cables. The specific cable type will depend on your speaker setup.

If you are using powered speakers, connect the cable from the Roland EX's "Audio Out" or "Line Out" port to the input ports of the speakers.

If you are using passive speakers, connect the cable from the Roland EX's "Audio Out" or "Line Out" port to the inputs of the external power amplifier. Then, connect the amplifier's outputs to the passive speakers.

If you are using amplified speakers, connect the cable from the Roland EX's "Audio Out" or "Line Out" port to the input ports of the speakers.

6. Turn on the external speakers and adjust their volume levels accordingly.

7. Set the Roland EX's volume level and tone controls to your desired settings.

8. Play the keyboard on the Roland EX, and the sound will be amplified by your external speakers.

It's worth noting that the Roland EX also has built-in speakers, so you may choose not to connect external speakers if you're satisfied with its sound output. However, connecting external speakers can provide a more immersive and powerful audio experience, especially in larger venues or for professional performances.

Remember to check the specific user manual for your Roland EX model, as the exact steps and available ports may vary slightly.
