ST-2815 FM transmitter 2w/8w/15w 88-108mhz Stereo PLL FM radio Broadcaster Wireles Microphone Double Switch

ST-2815 FM tranmsmitter, using aluminmum 1U standard chassis and improted bearing ball cooling fan, is upgraded a lot from previous models either in sound quality or ventilating sytem. The overall performance is much better. All connectors are at the back panel, leaves the front panel veyr simple and precise look. It has very professional look but simple operation.

Aside from FM transmission function, it can also use wireless microphone while the device is transmitting,it’s a pratical function applied.

The RF output power can be set to 2w/8w/15w, we’ll fix that before exit factory.

(Please note that we actually have two models for this: one is 2w and 8w adjustable, the other is 15w fixed power.They share the same chassis. Please let us know which output power you want,we’ll set before shipping.)
