ULTRA-COM II AIRCRAFT INTERCOM

Comtronics very popular two-place portable intercom was designed for pilot/copilot communication in high noise environments. Separate volume controls are adjustable by either pilot or passenger to meet individual hearing needs. This intercom can be used as an intercom only or a complete package with the addition of a single transceiver using a matching Comtronics radio interface cable with push-to-talk switch. The ULTRA-COM II integrates directly with all Comtronics headsets and helmets providing air-to-air and air-to-ground communication. This intercom includes a 3-foot adapter cord connecting to various external inputs such as a radio interface cable with push-to-talk switch for a single transceiver.

Creative circuitry has been designed with an automatic internal noise-canceling feature eliminating the bothersome "tweaking" when adjusting the background noise. This system also includes a unique side-tone circuit that allows the user to hear his or her own voice assuring proper operation.

Aircraft-grade metal enclosure virtually eliminates all stray radio interference. This circuitry is live all the time just like talking on the telephone.

The 9-volt battery is convenient because its gradual power reduction provides adequate warning of impending power failure. The ULTRA-COM II can also be used with a 12-volt power cord eliminating battery replacement. This cord come with a secure lock-ring and can be ordered either stripped and tinned or terminated with a cigarette lighter plug.

Features include a radio port for transceiver and cell phone, power port and music port which would also include capability for an iPod, iPhone, MP3 Player and camcorder.

There are two slide switches mounted on the circuit board next to the battery enabling a pilot to mix and match microphones. One switch can be placed in the "E" position for Electret Microphones and the other switch placed in the "D" position for Dynamic Microphones.

A face plate is available for panel-mounting the ULTRA-COM II Intercom.

An ULTRA-PAQ II Intercom Holder can also be added. This is a sturdy enclosure for shock-mounting the intercom to the airframe. Construction is a heavy-duty vinyl with hook-and-loop webbing. This is a nice adjunct keeping the intercom safer from vibration.

DUAL-COM II AIRCRAFT INTERCOM

The DUAL-COM II Intercom is a portable two-place unit designed for two-place aircraft and developed for high noise environments. This intercom has two separate volume controls which can be adjusted by either the pilot or passenger to meet individual hearing levels and integrates directly with all Comtronics headsets and helmets providing ar-to-air and air-to-ground communication.

It also has a toggle switch for Radio 1 and Radio 2. This switch allows pilots the option to transmit from either of two separate transceivers while monitoring both simultaneously. Since there are two isolated radio ports for use with two different hand-held radios, pilots can contact the ground crew on one transceiver while notifying a nearby airport on the other. All of this can be accomplished by using the switching circuitry provided.

Radio selection is controlled by one toggle switch located on front surface of box. Radio actuation is controlled by a single push-to-talk switch which may be mounted on the aircraft control stick.

This circuitry has also been designed with an automatic internal noise canceling feature which eliminates the bothersome "tweaking" to adjust background noise. Also included in the DUAL-COM II is a unique side-tone circuit that allows the user to hear his or her own voice assuring proper operation.

The aircraft-grade metal enclosure virtually eliminates all stray radio interference. Provisions for both a 9-volt battery and external power port are included. The power cord comes with a secure lock-ring and can either be stripped and tinned or terminated with a cigarette lighter plug.

A DUAL-COM II style interface cable is available for connection to Aircraft Radios, Motorola Radios, Marine Band Radios, 2-Meter Radios, FRS Radios, CB Radios, AM/FM Radios, Cell Phone Port, Music Port, iPod, iPhone, MP3 Players and Camcorders.

There are two slide switches mounted on the circuit board next to the battery. These enable a pilot to mix and match microphones. One switch can be placed in the "E" position for Electret Microphones and the other switch can be placed in the "D" position for Dynamic Microphones.

This intercom can also be panel-mounted using a DUAL-COM II FacePlate.

A DUAL-PAQ II Intercom Holder can also be added. This is a sturdy enclosure for shock-mounting intercom to airframe. Construction is a heavy-duty vinyl with hook-and-loop webbing. This DUAL-PAQ II is very well made and does an outstanding job!

Another excellent feature from Comtronics is an In-Line Passenger Push-To-Talk Switch. This switch shuts off the passenger's microphone so that 50% of the noise is gone! Just press the push-to-talk button to speak. The cable is portable and can be moved from plane to plane.


ITEM NO. 3002



PANEL-MOUNT IV AIRCRAFT INTERCOM

The PANEL-MOUNT IV Intercom is similar to the DUAL-COM II Intercom except it is designed to be permanently mounted in the instrument panel with the passenger plugging into the Remote Station Box. This intercom has a music kill switch and uses the DUAL-COM II radio interface cables.

Incorporated in this intercom is a toggle switch which allows the pilot to select between two transceivers for transmit while monitoring both simultaneously. Radio actuation is controlled by a 6-foot cable with a velcro strap and push-to-talk switch which can be placed in any convenient location within the cockpit. Custom straight cord switch assemblies for mounting can be supplied at no extra charge.

A pilot can contact the ground from one transceiver and notify nearby airports of his location on another. A separate remote station with volume control is supplied and may be mounted for student/copilot operation.

Located on the backside of the main enclosure are separate jacks for music input, push-to-talk cable, copilot Remote Station, Radio 1 and Radio 2. Music cords are also available for an additional charge. Also on the back is a power jack and a power cord is supplied with this intercom as standard equipment.

The entire circuitry is shielded and grounded to effectively eliminate FM and EMI interference. Heavy gauge aluminum with overlapping construction is used for the intercom and remote housing.


ITEM NO. 3006









DVX AIRCRAFT INTERCOM

Comtronics Model-DVX Intercom is a portable two-place General Aviation Intercom offering voice-activated and duplex circuitry - the best of both worlds. It incorporates a toggle switch to select between the "DUPLEX" Mode (live all the time) and the "VOX" Voice Activation Mode. With a flip of the switch, the pilot can select either mode depending on the communication requirement. "DVX" is taken from the letters in the words "DUPLEX" and "VOX" which describes the operation of this intercom. The "VOX" mode is used for cross-country flights. When operating in this mode, all microphone generated noise is eliminated until someone speaks.

"DUPLEX" mode is suited for ground operations and air traffic areas where radio traffic is heaviest and when intercom doesn't pop in and out. It is suitable for run-ups, taxiing, hearing the engine on take-off and landing - any place where background noise is needed to be heard.

Voice-Activated "VOX" mode provides a quiet and restful operation. Most pilots select this mode once they have reached altitude/cruise and radio transmissions are less frequent. Also, this circuitry is probably the fastest voice-activated circuit available as it responds to the spoken work in two-milli seconds. With a "VOX" circuitry that quick, there will never be any missing syllables at the beginning of any transmission.

For radio hook-up, it has a built-in interface cable with General Aviation plugs. It also has a 5-pin DIN auxiliary jack that can also be used to connect a music source or a DVX Rear Seat Intercom for 4-place operation.

The Model-DVX Intercom is powered by an internal 9-volt battery. There is also a 12-24 volt power jack located on the backside of the box that may be used with a hard-wired system or can be plugged into the aircraft cigarette lighter jack for portable operation.

  • Expandable to 4 or 6 Place
  • Accepts all General Aviation Headsets
  • Single VOX Sensitivity Control
  • LED Indicator -ON/OFF
