Because the 8V supply voltage is switched off when dynamic microphones
are used during glider flight the second (copilot) headset microphone is
disabled.
A maximum of two microphones of same type may be connected to each
microphone input channel.
5.6.2. Earphone Connection
Several earphones of same type can be connected in parallel. The total
impedance should not be less than 60 Ohms.
5.6.3. External Audio Input
Audio alarms or even music can be made available via the external audio
input. When this input is not used it must be connected to ground in order
to avoid noise. PIN5 must be connected to Battery minus (GND).
