Digital PLL Stereo FM Transmitter typical applications：

• Professional quality for tr ansmitting TV sound at exercise clubs

• Great for transmitting messages for realtors, state fairs, drive-ins, etc.

• Transmit music / MP3s from your home computer to your stereo

• Transmit mp3 players/walkmans/portable CD players to your

• Car Stereo

• The ideal campus or school radio station

technical parameters：

• Frequency: 87.5-108.0MHz (custom-built frequency is acceptable)

• Display mode: LCD matrix screen.

• Frequency adjusting mode: “DOWN” & “UP”, short press for 0.1MHz scantling setting (long press for speed)

• Frequency saving mode: auto save, power-off memory

• Warp of modulate: ≤±75KHz（100%）

• Sensitivity of modulate: 600mV

• Response of audio frequency: 100~15000Hz

• Audio distortion: ≤0.2%（F=75KHz，f=1KHz）

• S/N ratio: ≥60dB（1KHz 100%）

• Separate level of stereo: ≥-60dB（200~15000Hz）

• Transmit power: 5W

• Power supply:  DC12V

• Dimension: 225（L）x 145(W) x 36(H) mm 

operate instructions: 

• When first time to use, after scanning the circuit mode, the system would transmit the default frequency: 99.9MHz automatically.

• Pressing “up” button once, frequency would increase 0.1MHZ, if hold on pressing more than 1second, it would increase fleetly

• Pressing “DOWN” button once, frequency would decrease 0.1MHZ, if hold on pressing more than 1second, it would decrease fleetly

• Pressing “S/M” button to realize the switch between “STEREO” & “MONO” (inefficacy when mute)   

• Pressing “MUTE”button, mute output.

• press  the key " m1 to m4" ,it will show stored frequency.

• In any frequency, you can press  on "m1-m4" long time, it will memor this frequency.

• Need not to set the frequency every time to use, the system would save the last setting of frequency.
