What is Multicast?¶

The multicast function allows you to transmit the screen contents including sound from one device via a paired transmitter to multiple displays simultaneously.

Multiple participants have the option to transmit their screen contents to multiple displays at the push of a button. However, only one participant can perform this function at a time.

• Supported devices: QuattroPod USB under the function Type-C or Mobile, QuattroPod Standard/Deluxe, or QuattroPod Mini.

• You need a WLAN access point.

• Your router must accept the QuattroPod transmitter / receiver broadcast packets.

• All QuattroPod receivers must be in the same network.
