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 K 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 K 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.

The maximum balanced input signal before saturation of the input
stage of the amplier occurs with respect to the amplier’s gain is
presented in the chart below. Input signal: 1kHz sine wave. Voltage

7.3 Input select
K 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 or not.
The up and down buttons on the “Input select” screen toggle
between the available input sources. The “sel” button locks the
selected option.
The possible input/signal path congurations are:
▶
Analog ==> Out (analog input and direct output)
▶
Analog ==> DSP ==> Out

7.4 Max output voltage
The max output peak voltage of K series ampliers can be set
by the user. It is possible to set output peak voltage levels for
channel 1, channel 2 or both by pressing the “C1+2” button. The
“+” and “-” buttons change the value of the max output peak
voltage.
