Aphex 141 - Manual (Page 2)

1.0 Introduction
The Aphex Models 141, 142 and 144 were developed as interfaces between the Aphex Anaconda
digital snake system and other devices. Each model was designed to do its job without any extra
unnecessary bells or whistles. While they each fulfill that design specification, each model is an
excellent, useful product in it own right.
Since the I/O of the Anaconda is ADAT, there is an ADAT connection in each model. The ADAT eight
channel format has been a standard in the audio industry for years. It is a reliable, mature, cost
effective technology albeit with limitations. The prime limitation is the distance that ADAT audio can
be safely transmitted through ‘Lightpipe’ fiber. Some claim that it could be as far as 30 feet, but our
experience shows that there can be significant audible artifacts at 20 feet. We strongly recommend
that the distance be as short as possible, preferably less than 10 feet (3 meters).
The other limitation is that its maximum sample rate is 48kHz for eight channel operation. There is
a technology called S-Mux that doubles the maximum frequency but halves the channel count. We
have elected to stay with the sample rate of 48kHz in the Model 142, but Models 141 and 144 can
work at 44.1 or 48kHz.
There are many other products on the market that do similar functions. But none as simply or as
well or as cost effectively, as these units. You will enjoy many years of excellent uninterrupted
performance.

A MESSAGE FROM THE PRESIDENT
Dear Aphex Customer,
Congratulations on your purchase of the Model 230 Master Voice Channel.
Discriminating people have successfully and happily used a combination of Aphex microphone preamplifiers and processing for years even
though it required using different boxes and additional interconnections. The Model 230 combines the proprietary circuits and features that
made those individual products so effective and great sounding along with powerful new proprietary circuits. All these circuits make the
Model 230 the best sounding and most flexible, yet easy to use, voice processor on the market. On air or in the production room voices will
be more intelligible, have greater presence and fullness, and have more consistent levels- all while retaining their unique characteristics.
As with all our products, we are extremely proud of the ingenuity of design and the manufacturing quality of the Model 230. We love to
hear from you, our customers, about your experiences with any of our products. Our customer support is unmatched in the industry, so
please do not hesitate to contact us.
Sincerely,
Marvin Caesar
