Portable intercom IC-4

IC-4 is a lightweight, portable air intercom system designed to work both with headphones and stereo mono (mixed configuration is possible). Four pairs of headphone jacks let you plug in any combination of four pairs of air headphones of similar impedance. The compact size (110 x 880 x 380 mm) and extremely low weight (359gr) make the IC-4 portable device in the full sense, for which place in our air bag can be downloaded. In this way we will be prepared to fly a plane, which for example does not have built a permanent intercom.

IC-4 is made of tough ABS plastic type. Corners of cover are also rounded in order to increase the resistance to any injuries during the operation. Also, internal components have additional strengthening to ensure improved portable as befits strength.

Simple and logical layout of components on the front panel makes operation of the device even intuitive. All slots are clearly labeled and separated according to the layout of seats on the plane and placed in the center switch to RADIO / INTERCOM allows if necessary to isolate a pair for a work crew from the passenger pair. On the panel we find than this: the PTT button, two stereo mini-jack sockets (IN / OUT) for connecting an external device registration, mp3 player, or for example a mobile phone, and two knobs used to adjust the volume and VOX sensitivity (auto-mute) . Over the volume knob has been integrated with the power switch.

IC-4 has a built-in battery compartment for 9V supply. Battery power supply lasts for approximately 25 h of continuous operation. It is also possible to connect the intercom to an external power supply (eg cigarette lighter). IC-4 tolerates voltage in the range of 12-28V. Connecting an external power supply to disconnect the battery.

DETAILED DESCRIPTION OF ACTION:

When you turn on the intercom (volume control) when not connected headset, PTT button will light up red. When in any of the outlets will be placed the headphone jack, and the option will be enabled voice VOX - PTT button, the red light goes off. If after inserting the pins and attempt to activate a voice of light still remains lit, this means that we should increase the sensitivity of the VOX circuit.

Intercom circuits allow simultaneous connection of mono and stereo headphones in any combination. It is also possible to connect different models of handsets under the condition that the internal impedance will be close.

Pressing PTT will obtain exclusive by the commander, also in relation to the co-pilot access to voice communication with ATC - All other microphones are muted. Switching intercom RADIO mode only limited radio communications for crew members isolating earphones passengers. The function "fail-safe " protects against the loss of communications in case of power failure - the commander of the handset is switched directly to nest on-board radio.

Intercom has a mini jack input (IN), allows to connect an additional audio source (MP3 player, CD player, phone). The volume signal from the Mini Jack is automatically muted in the case of activation of the VOX or ATC message appeared. Mini jack output (OUT) knock intercom connected to an external audio recorder to save messages such as ATC. Both inputs (IN, OUT) can also be used to connect your mobile phone for safety reasons but definitely not recommend carrying cell phone calls during flight.

As you can see the IC-4 is a simple but fully functional, four-miescowy intercom, having a number of features not found even in much more expensive models. Rugged, reliable design ensures safe and comfortable operation to over the years.
