ground connections are made directly to the dedicated music signal and ground inputs on the AeroPanel 100.
The power for IFE and audio panel should be a common bus.
If a music jack instead of a Bluetooth music source is installed for Music 1 or 2, we recommend grounding
the jack to airframe ground.
NOTE
Adding a high-performance audio control system, particularly in conjunction with high-performance active
noise canceling headsets, cannot improve on older avionics that were designed for cabin-speaker use. Ben-
dixKing makes no claim that the audio panel will provide a noise-free audio quality under all installation
conditions, particularly with older avionics.
2.4.2
Headphone Wiring
In order for the IntelliAudio® spatial audio to perform correctly, the audio panel
must be connected
to stereo
headsets, and the left/right outputs wired correctly as shown in
2.4.3
Power
The AeroPanel 100 is compatible with both 14 and 28 Volt DC systems. A five (5) Amp circuit breaker is
required for all installations. Power and ground wires should be #22 connected to J2 Pins 8 and 9. Connect
airframe ground to J2 Pin 10 and 11 only. No dropping resistors or forced air cooling is required.
2.4.4
Audio Panel interface
The AeroPanel 100 is designed to interface with standard aircraft avionics, and presents a 510
receiver
impedance. For best results, a twisted-shielded cable is recommended from the avionics audio source to the
audio panel, with the shield grounded at the audio panel end.
Some avionics do not provide a separate audio low, and may introduce additional electrical noise into the
system. For best results, connect the audio low from the audio panel to the radio ground, using one conductor
of the twisted-shielded cable.
2.4.4.1
Speaker Load
The AeroPanel 100 contains one speaker amplifier, and does
not
provide a speaker load for legacy units.
Some units with internal speaker amplifiers, such as the King Radio KX170-series, require a resistive load
to prevent damage if their speaker amplifier is not used. Connect the speaker output from the legacy radio to
an external speaker load of at least 16
, 3W.
2.4.5
Transmit Interlock
Some communications transceivers use a transmit-interlock system. To fully utilize the Split Mode feature,
this function must be disabled. Consult that manufacturer's installation manual.
2.4.6
Backlighting
Control of the GREEN and
WHITE
button text and backlighting
is through the aircraft avionics dimmer For 14 V aircraft, connect
J2 Pins 6 and 7 to the aircraft dimmer bus, and pin 5 to ground.
For 28-volt systems, connect pin 7 to the aircraft dimmer, and
pins 5 and 6 to ground.
If an external dimmer control is
not
used, or the dimmer voltage
is less than 0.5 VDC, the white text will be at full intensity.
There is a backlighting adjustment, see
2.4.7
Unswitched inputs
J1, pins 31, 29 and J2 pin 15 are unswitched, unmuted (by transmitter keying), inputs # 1, 3 and 4, respec-
tively. These inputs are presented to the pilot and copilot regardless of the audio configuration, and will
always mute the entertainment inputs. These 510Ω inputs can be used for altimeter DH audio, GPS waypoint
