Echo device, also known as an amplifier, and some call it a mixer. The device is new and unused. I ordered it from Malaysia and it just arrived. You can connect speakers with ohms to it. You can also connect it to an amplifier for better sound quality. The price for the device is only 250 SAR. New - New - New. If you want the microphone from the same company, add 150 SAR. So, device + microphone = 400 SAR. Contact me.
