• 1 Audio & Video Output Connector - You can send your A/V signal to an external sound system, recording device or TV.
• Patented 16-Channels UHF PA Broadcasting® Transmission & Receiving Function - You can send audio signals wirelessly to other Roadmasters.  This is one of the hottest functions invented by Acesonic's design team that that no other machine can match. Imagine if you need a ballroom or a park full of your sound, what do you need to do?  In the old way, you would have to run lots speakers cables from your amplifiers to each one of the speakers, it is not only a big hassle but also a dangerous task.  With PA Broadcasting®, you can set one of your Roadmasters as the 'master', and all of its audio signal will broadcast wirelessly up to a 300 ft range.  For the rest of your Roadmasters, you just have to turn on the 'slave' function and it will receive signals up to 300 ft away.  You can set as many Roadmasters as 'slaves' as you want in the area to make sure your sound is heard loud and clear. You just have to make sure the 'slaves' are set to the master's broadcasting channel. 
• All the Roadmasters also come with a Broadcasting Relay® function. With the Broadcasting Relay® function, all Roadmasters can retransmit signal out on one of its 16 channels.  This means if you want to cover 600 ft of range, you can put 3 Roadmaster in the given area.  When the 1st 'slave' Roadmaster receives the audio signal, it will retransmit the signal out so that the 2nd Roadmaster 'slave' that's 300 ft away will also receive your signal.  You have 16 channels so potentially you can relay up to 300 ft x 16 = 4800 ft away.  When the signal is transmitted wirelessly, you can make sure there is no audio delay for audiences that's far away from you.  If the 100 watts of sound is not enough for you, you can connect to an additional sound system using its internal power source.
