Since the maximum signal or numerical value which can be faithfully
converted constitutes the practical upper limit for all AD/DA converters, this
limit is represented as (FuII Scale) in the level display and signfies that
the analog input signal is just barely at the level at which numerical overload is
about to occur. However the lights starting at a level of ,
thus providing a warning of impending overload before it actually occurs.

In any digital system, it is desirable to use as many ''bits'' as possible in order to
keep the noise component of the signal to a minimum (each bit used
corresponds to approximately additional signal-to-noise ratio).6 dB
The level at each of the 16 inputs is displayed via a 5-segment peak indicator.
The and are equipped with a peak-hold function for improved
readability. The LEDs light in succession at the following signal levels

As a basic rule of thumb for optimal recordings, input signal levels should be
adjusted so that the s never or only very seldom light - that is, as high
as possible without causing overloading. This ensures that all bits will be used
and that the noise floor will be as low as possible.

The A16 Ultra is equipped with
balanced inputs and outputs. The A16
Ultra can be adapted to various
standards via the DIP switches on its
rear panel. The analog inputs can be
set in groups for an input sensitivity of
either or . The same
applies to the analog outputs.
