DIGITAL/ANALOG STEREO ENCODER

The Digilog is a microcomputer controlled stereo encoder that combines the best of analog and digital techniques for fantastic performance. Designed for optimum stereo seperation and excellent spectral cleanliness this encoder will provide that extra performance for radio stations who want something a little special.

Audio baseband filtering combined with the latest digital techniques and post MPX filtering make this unit easily conform to even the most stringent broadcast regulations. And because the energy from the encoder is in the right places you will gain extra loudness inside your bandwidth limits.

The ultra low distortion pilot tone will allow excellent compatibility with subcarrier services such as the Radio Data System (RDS) High quality components and printed circuit board will ensure you have 24 hour operation for years and years.

The internal power regulator allows the encoder to be run from 8 to 18 volts but still employ a split rail power supply for maximum dynamic range.Balanced input chips are onboard as standard allowing balanced output professional mixing desks and audio processors to be connected to the encoder.
The encoder will function with any composite/mulitplex/mono transmitter/exciter.

ENHANCED TRULY DIGITAL DSP STEREO ENCODER WITH LIMITER AND COMPRESSOR!

This completely redesigned unit uses DSP to generate pilot and process audio in ways which are very difficult or close to impossible to do with usual analog technology. And it does all that in exceptionally small factor! It has many advantages over SE-3 and previous version SE4; brick-wall low pass audio filter with a sharp 19KHz notch, limiter and compressor, improved pilot generation due to DSP, stereo/mono switch with LED indication, balanced and unbalanced audio inputs, increased channel separation, precise preemphasis, less noise, on-board power connector and an optional LCD display connector. Optional LCD control unit makes it possible to set treble, bass, preemphasis and compressor settings. SE4 can be connected to MAX PRO III via dedicated data cable making it possible to control both units via single LCD control unit. Cost-efficient and simple. Designed specifically as a companion for all MAX PRO series exciters, but is also compatible with any FM exciter. All the connectors and switches are mounted on the board so connecting this unit requires no additional soldering. Mounting holes are compatible with SE3. This is a perfect stereo encoder for beginners and professionals.

Here is the manual for the new SE4 DSP+ stereo encoder

Here is the manual for the LCD module

Why is SE4 DSP + so great?
- Perfect for any mono FM transmitter, effective output level of 1V, 2V and 4V can be selected with jumpers
- DSP technology enables extremely sharp filters and a very deep notch at 19KHz!
- Small form factor!
- Drop-in replacement for SE3 and SE4! Same mounting holes as SE3 and SE4, only slightly longer!
- On-board DC converter.
- Balanced or unbalanced audio inputs. This effectively eliminates annoying ground loops and hum.
- LC filtered MPX output signal.
- Built-in limiter, low pass filter and compressor/limiter, all controlled via backlit LCD display and keys. Same LCD unit can control MAX PRO 3 and SE4 DSP+ at the same time, if you connect the two units with the I2C cable!

How is SE4 DSP+ better than SE4?
- DC converter is not synchronized with stereo pilot
- Additional anti-aliasing low pass filter enhances signal/noise ratio
- Improvements for better stereo separation
- Improved board layout
- Reduced heat generation (7805) by about 50%.

BY FAR THE BEST PERFORMANCE FOR THE MONEY, NOW EVEN WITH RDS CAPABILITY!

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.

Here is the manual for the new MICRO MAX ST-1 stereo encoder
