  • TWS Mode Capabilities and Restrictions

    You can connect two Partybox speakers together in TWS Mode by pressing and holding the Bluetooth button on both speakers simultaneously for 5 seconds. If you connect an instrument or microphone to one PartyBox speaker while using TWS, the instrument or microphone connected to one speaker will be reproduced by this speaker alone. You will not hear the instrument or microphone in both speakers. If it is necessary to have instruments reproduced by two or more PartyBox speakers, it is possible to use an RCA cable – connected from the RCA outputs on the speaker that the instrument or microphone is connected to, wired to the RCA input of the secondary speaker. Alternatively a small mixing console can be used - connecting audio sources to this mixer and sending the mixed audio signal to the speakers with a wired connection.
