New! AMX-2A

10 Channel Audio Mixer Amplifier

"Mini Audio Panel"

AMX-2A Installation Guide(.pdf)

  • Allows the connection of up to 10 additional comm, nav, flight instrument, alarm, warning and other audio sources to existing and newly-installed aircraft audio panels or intercoms.
  • Convenient volume controls provided on four of the 10 inputs simplifies the connection to fixed level audio sources that do not have their own adjustment capability.
  • High output drive and unique output structure allows direct attachment to comm audio when the intercom or audio panel does not provide Auxiliary Inputs.
  • May be used as a headphone power booster by connecting the inputs to an existing headphone bus and driving additional headphones with the outputs.
  • High quality audio output drives up to 32 mW RMS into 150 ohms, 50 Hz to 15 KHz (-3 dB).
  • Directly connects to and compatible with most commercial audio panels, intercoms and aircraft headphones.
  • Space-saving 25-pin D-Sub Backshell package allows easy installation.
  • Low current drain, typically less than 50 mA.

IL-4A, IL-12A

Four and Twelve-Channel Annuciator Lamp Controllers

IL-4A Datasheet (.pdf)

The IL-4A device is a four channel annunciator lamp controller.  It allows monitoring of up to eight circuits for a mix of active-high (powered) or active low (grounded) switched inputs.  Two isolated inputs per channel share one annuciator lamp.  Flexible power source inputs are provided, allowing  lamp dimming from a panel dimmer bus, or powering from redundant sources.

The IL-4A device drives LED lamps or incandescent lamps up to 100 mA each.  A push-to-test input allows integrity testing for all lamps.

The IL-12A is identical in function to the IL-4A, except it is provided in 12-channel form on one circuit board assembly.

AMX-1A

Sigtronics Audio Bus Expansion Device

AMX-1A Datasheet (.pdf)

The AMX-1A is an audio bus expansion device that simplifies the connection of shielded audio wiring to Sigtronics SPA-400 and Sport-200 intercoms*. It adapts the 12-pin intercom box connector to a 50-pin D-Sub connector for local panel wiring, and to a 15-pin D-Sub connector for off-panel wiring, such as remote or back seat headset jacks or stick-mounted switches.

Four of the ten audio channels are provided with on-board series resistors, allowing direct connection to low-impedance audio sources such as some VHF Comms and external music inputs. One audio channel supports a volume control to simplify the connection to sources that do not allow audio level control, such as some EFIS systems or engine monitors.

All audio connections have two grounds associated with them-- which may be connected to cable shields and signal grounds, as required. Controls such as push-to-transmit signals each have one associated ground. This plethora of grounds greatly simplifies the wiring of any required shielded cable.

Go to www.sigtronics.com for more information on the SPA-400 and Sport-200 intercoms.

*Note: Can be used with Sport 200S (stereo) intercoms, however headsets and music inputs must be wired directly to the intercom. The AMX-1A is then used to support all of the monophonic audio sources.

RM-1B

Wiring Harness Expander for the Rocky Mountain Instrument Micromonitor Engine Monitor

RM-1B Datasheet (.pdf) (product shipped prior to September, 2006)

RM-1B Datasheet (.pdf) (product shipped since September, 2006)

The RM-1B device simplifies the wiring to a RMI Micromonitor engine monitor by providing two expansion connectors.  Firewall forward connections use a 50 pin D-Sub and panel connections use a 15-pin D-Sub.  Using two connectors this way allows for a panel to be disconnected and removed from the aircraft.

The RM-1B device mounts directly to the back of the Micromonitor controller tray, replacing the stock 36 pin edge connector. On-board volume control allows the adjustment of audio levels without disassembling the engine monitor. An alarm buzzer is mounted to the board(not shown in photo), simplifying wiring and mechanical mounting.

On-board transient voltage suppression helps to protect the engine monitor from electrical surges on the main electrical bus during engine cranking.

The RM-1B device supports the Micromonitor serial input/output capability (announced March, 2005).

Go to www.rkymtn.com for more information on the Micromonitor engine monitor.

Mating Connectors

D-Sub connectors come in several styles from different manufacturers. They are available from traditional electronic distributors such as Digikey www.digikey.com, or Mouser www.mouser.com; or from aviation sources such as Steinair, www.steinair.com

Recommended parts are the Norcomp Series 170 connector plugs and sockets and Series 977 or 977 backshells. Amp Series 109 machined pins are recommended (yes, they do fit in the Norcomp plugs and sockets). Crimpers and insertion/removal tools are also available. All are available from www.steinair.com who also can provide all of the wiring supplies that you require.

Steinair part numbers:

SA-1011 9 pin male plug
SA-1012 9 pin female socket
SA-1020 9 pin backshell

SA-1013 15 pin male plug
SA-1014 15 pin female socket
SA-1015 25 pin male plug
