7 Amplier Settings
7.1 Output attenuation
The output attenuation screen sets the amplier’s output
attenuation level. The user can choose whether to set output
attenuation for channel 1, channel 2 or both by cycling through the
right most button. The “+” and “-” buttons change the value of the
output attenuation in the range from 0 to -30dB. A single “+” or
“-” button press will increase or decrease the output attenuation
by 1dB. Note: for ideal sonic performance, select a 0dB output
attenuation (meaning no attenuation), and select the proper
gain/sensitivity level as explained in the next paragraph.

7.2 Input Gain/Sensitivity
All Duecanali Series ampliers allow selection of input sensitivity
to allow correct sensitivity matching with other third party
equipment. The user can choose whether to set the input gain/
sensitivity for channel 1, channel 2 or both by cycling through the
right most button. The “+” and “-” buttons change the value of the
input gain and corresponding sensitivity. The allowed gain values
are 26dB, 29dB, 32dB and 35dB. The table below shows the input
sensitivity values for the Duecanali Series ampliers. These are the
maximum RMS voltage values of an input 1kHz sine wave before
clipping occurs at the output stage. These values are reported
with respect to the amplier’s gain.

7.3 Input select
Duecanali Series ampliers allow the user to choose three different
input modes (if available): Analog, AES3
1 and/or 2
, and KAESOP
2
.
Each of these inputs can either be processed by the internal DSP
