A MESSAGE FROM THE PRESIDENT
Dear Aphex Customer,
Congratulations on your purchase of the Model 1788A remote controlled microphone preamplifier. Years of
research and development were required to overcome the hurdles that similarly purposed products do not even
address. Additional years of use of the original Model 1788A in some of the most critical audio applications
resulted in the significant improvements that are embodied in the 1788A.
The primary improvement is the use of TCP/IP protocol over Ethernet for remote control. Execution of control
commands as well as metering feedback is almost instantaneous for 128 channels.. The control can be achieved
via an extremely powerful yet easy to use software package (PC or Mac), a dedicated hardware remote controller
Model 1788A-R, or anything that talks MIDI.
Of course, the same unique features that made the 1788A so functional and great sounding are still included
in the 1788A. Included is the Digitally Controlled Low Noise Amplifier (LeNA™) that provides glitchless and
noiseless gain changes. The MicLim™ is a limiter that is in front of the preamp that virtually prevents overload.
The Drift Stabilized A/D™ eliminates the need for the high pass filter in the digital domain and also assures
maximum resolution. All these patented features make the 1788A an indispensable tool for live or studio
applications.
We are extremely pleased that you have joined the elite of the audio world that appreciate the benefits that
only the 1788AA system provides.
Very truly yours,
Marvin Caesar
President
