Power Amplifier
Select a power amplifier from the list box. The specifications of compatible types appear, as follows.
Mode display: Stereo and bridge details for the selected amplifier are displayed.
Output channels
The value shows the maximum output power of the amplifier. The value is under the conditions of 120 V and 1%
distortion for a 20 Hz to 20 kHz input. This value is used by the clip level indicator. SPL distribution or frequency
response does not depend on the power voltage. The specifications of amplifiers are available at
https://www.yamaha.com/proaudio/
. The level at which the clip indicator lights depends on the power voltage
of the amplifier. You can set the power voltage under System in the Project Properties window.
Clip indicator (circle above power amplifier list box): The indicator turns red when the peak output signal exceeds
the maximum output power of the amplifier. When Sineis selected in the Sourcelist box, the peak output
signal is 3 dB (two times) higher that the actual output value. When “Pink” is selected, the peak is 6 dB (four times)
higher. When “Music” is selected, the peak is 10 dB (10 times) higher. The peak output capacity of the amplifier is
3 dB (two times) higher than the actual power value. Comparing these values, the indicator shows whether the
output signal is within the capacity.
Input an attenuation level for the power amplifier in dB. Maximum is 0 dB and the minimum is -60 dB.
The value shows the gain of the selected amplifier with the entered attenuation value.
