9 : 1.Amplifier settings: Output attenuation
The output attenuation screen sets the amplier’s out-
put 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 -30 dB. A
single “+” or “-” button press will increase or decrease the
output attenuation by 1 dB.
Note: for ideal sonic performance, select a 0 dB output
attenuation (meaning no attenuation), and select the proper
gain/sensitivity level as explained in the next paragraph.
9 : 2.Amplifier settings: 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/sen-
sitivity 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 26 dB, 29 dB, 32 dB and 35 dB.
TABLE 3 shows the input sensitivity values for the K
Series ampliers. These are the maximum RMS voltage
values of a 1 kHz sine wave input before clipping occurs at
the output stage. These values are reported with respect to
the amplier’s gain.

26 dB 4.48 V 5.30 V 5.11 V 5.50 V 6.34 V 7.37 V
29 dB 3.17 V 3.75 V 3.62 V 3.90 V 4.49 V 5.22 V

TABLE 4: Maximum balanced input signal vs 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 TABLE 4.
9 : 3.Amplifier settings: Input select
K Series ampliers allow the user to choose three dif-
ferent input modes (if available): Analog, AES3
1
and/or
KAESOP
2
.
Each of these inputs can either be processed by the
internal DSP (if installed) 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 available signal routing path congurations are:
 Analog  Out
Analog input and direct output
 Analog  DSP  Out
1
Analog input routed to the internal DSP
 AES3  Out

9 : 4.Amplifier settings: 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 chan-
nel 1, channel 2 or both by pressing the “C1+2” button. The
“+” and “-” buttons change the value of the max output peak
voltage. Available voltage ranges for each model are shown
in TABLE 5.
