This FM Transmitter comes ready-assembled, in its own durable enclosure. You can operate this unit on any AC mains voltage in the world. With the right lead it will also work on a 13.8V DC (sometimes referred to as 12V) vehicle power supply.
The design utilizes a low power oscillator VHF amplified to 100mW of power and phase-locked with a chain to a reference divider quartz oscillator. The 100mW signal is then applied to a 12 pole low pass filter that produces RF final RF output. All this is housed in an metal case fully screened to protect the user from direct contact with RF voltages and to prevent unwanted emissions, local interference and provide to the unit with sufficient RF immunity for the proper operating in an industrial environment.
Frequency is selectable by means of dip switches and pre-emphasis is selectable ( 50us/75us/none ) by means of jumpers. This FM transmitter accepts a standard line input from compressor limiters, audio mixers, DVD players, CD players, computer sound cards etc. by way of 2 x RCA phono sockets mounted on the rear of the unit.
