SMD DIGITAL/ANALOG STEREO ENCODER WITH LIMITER AND EASY RDS UPGRADE PATH

This is our new miniature stereo encoder, performing somewhere between our low cost SE3+ and high performance SE4 DSP+. Indeed, it is amazing how much
performance you can squeeze from such a small unit, thanks to SMD technology; there's limiter with peaking leds, balanced inputs (XLR), low pass filters, precise selectable preemphasis and MPX filter. DOES NOT use crappy Rohm chips! Uses DSP techniques to generate pilot and process audio. And it does all that in exceptionally small factor. If you're not impressed yet, note expansion pins on the pictures below. You can easily expand functionality by adding a plug-in RDS daughter-board. Wiring-up RDS encoder has never been easier than this. Plug it in and enjoy a wide array of Radio Data System functionality.

Key features:
- Perfect for any mono FM transmitter, effective output level of 1V and 2V can be selected
- Small form factor
- Balanced inputs (XLR), this effectively eliminates annoying ground loops and hum.
- Easy to add RDS encoder by installing plug-in RDS board
- LC filtered MPX output signal.
- Built-in limiter, low pass filter and preemphasis
