Post SE4 DSP stereo encoder Reply with quote

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 - same size as SE3! It has many advantages over SE-3;
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
