A MESSAGE FROM THE PRESIDENT
Dear Aphex customer,
Thank you for selecting the Model 228 as your interface between consumer level outputs and professional level
inputs.
By using this interface you will improve the sonic performance of your installation - setting levels for exact
balancing between different channel outputs and devices will be very quick and simple, gain structure will be
idealized for the lowest noise, and balanced lines will make your system more immune from induced noise.
Even though the Model 228 is a relatively simple design there was a great deal of research and thought that
went into its development. We trust that you will find its performance and features equal to what you have
come to expect from all Aphex products.
Very truly yours,
Marvin Caesar
