P1-22
HDPH2_B
OUT
Balanced output for headphone(s) 2
• The headphone 1 output is a balanced, transformer-coupled output providing nominal
300 mW into 75 Ω.
o Use a shielded single wire for headphones requires an unbalanced output
configuration. To get this connect P1-3 to GND.
• The headphone 2 output is a balanced output providing nominal 200 mW into 75 Ω.
• You can connect up to two headphones with phone-impedance of 300 Ω (or higher) in
parallel on each circuit, therefore you can connect up to four headphones at the same
time.
• We also recommend to install the jacks generally isolated from car frame in order to
prevent ground loops.
CAUTION: The headphone 2 output shall be always floating (cannot be connected in
unbalance configuration as headphone 1).

Illumination high input
• The VHF transceiver supplies illumination for the keys and the display.
• It depends on configuration if the illumination is controlled with front panel or externally.
• It depends on configuration if 14 or 28 V fixed illumination voltage is used or aircraft
dimming-bus voltage is in operation.
o Connect ILL_LO (pin P1-10) to aircraft ground.
o Connect ILL_HI (pin P1-23) to dimming bus.

• The AF auxiliary input is used to connect an external audio source (NAV, music-player,
etc.) to the transceiver.
• The external audio is audible only when transceiver is in receive mode.
• The input sensitivity is adjustable in the configuration setup.
• The impedance of this input is 600 Ω.
