Standby is too insensitive
When standby is too insensitive, the KH 80 DSP switches to standby when it is not supposed to
or does not wake up from standy when it is supposed to .
Possible reasons:
The standby threshold level is above the signal level . When the input and output levels of
the KH 80 DSP are set very low but the source has a very high level, this leads to a very low
audible output signal .

In backplate mode, increase the output level of the source or the input and output levels of
the KH 80 DSP in order to increase the sound pressure level above the standby threshold .
X
In network mode, increase the output level of the source or the input and output levels of
the KH 80 DSP in order to increase the sound pressure level above the standby threshold .
• Set the standby time to the desired time (for test purposes you can set it to a shorter
time) via the Neumann .Control iPad
®
App
• Set the standby level to a lower level (e . g . 17 dB) via the Neumann .Control iPad
®
App .
• Set the SETTINGS switch on the back of the KH 80 DSP to NETWORK CONTROL - AUTO
STANDBY = ON
In general, you should keep the gain settings of the loudspeaker as low as possible (e . g .
INPUT GAIN control - 0, OUTPUT LEVEL switch 94 or 100 dB SPL) and the level of your source
as high as possible to get the best signal to noise ratio and keep induced disturbances as low
as possible .
The wakeup signal depends on the level which is connected to pin 2 of the XLR (Tip of the TRS
jack) connector . If an unbalanced signal is connected to pin 3 of the XLR connector (ring of
the TRS jack), the signal cannot be detected . In this case the signal is also inverted in phase .
Ideally, the source should be connected to the loudspeaker via a balanced XLR to XLR or XLR to
TRS jack cable . If there is only an unbalanced source available, the connection should be done
according to the following diagrams .

We recommend performing a reset of the KH 80 DSP (see “Resetting the KH 80 DSP”
on page 11) to make sure there are no unreasonable values set . After that, create a
new system with the Neumann .Control iPad

App to prevent original values from being
transferred to the loudspeakers again .
