Pro Intercom econoCom EC4E (4 Beltpacks + 4 Headsets)

An econoCom system consists of:

1) A table-top (AD2410) AC adaptor with  removable IEC power cord, and a cable with connector which connects the AD2410 to the PS4 interface box, and;

2) A PS4 system interface. These two devices, taken together, are the system's power supply.

Also included in the EC4E:

  • 4x Standard full-featured BP1 belt packs
  • 4x SHM210 headsets with connector

The system does include a signal light feature.

The econoCom power supply components are not intended to be used in systems which include more than two loudspeaker stations or stage manager stations, and do not provide multiple circuits.

One to six more BP1 belt packs (for a maximum total of ten) may be added to the system without creating hum or overheating the power supply components.

The PS4 system interface provides precise voltage regulation, further smoothing of the DC current (AC hum elimination), automatic overload/short-circuit protection, the necessary termination network for the intercom circuit, an LED indicator which indicates that 24VDC is being delivered, and 3 paralleled XLR jacks for connection of headset stations or strings of stations in a party-line configuration.

The components of an econoCom system are connected together using standard 2-conductor shielded microphone cables fitted with 3 pin XLR connectors (male/female). The PS4 has three outlets which are in parallel and the BP1s have a male and a female XLR for connecting to the PS4 and for looping onwards to the next BP1.

The ribbed, extruded aluminum case, polypropylene end bezels, internal support system for the PC boards, and best quality XLR connectors all contribute to the outstanding ability of the system components to withstand rough usage.

The comparatively low price of an econoCom system is made possible by the minimized assembly costs resulting from simplicity of construction. Simple construction also affords the use of higher quality components, and increases the ease (thus lowering the cost) of servicing.

The econoCom components are fully compatible with Clear-Com® and other popular (200 Ohm, unbalanced) party-line headset intercom systems.


Pro Intercom BP-1 Single Channel Belt Pack


Performance: The BP-1 portable headset station may be worn on the belt or hung on the wall by its sturdy belt-clip. Soft plastic strips on the underside help hold it in place when set on top of a console. The matte black finish minimizes visibility.

Frequency response has been carefully shaped to optimize both intelligibility and long-term listening comfort. A mic. limiter circuit reduces overload distortion. The high bridging impedance ensures that system and sidetone levels do not vary as other stations are switched in and out of the circuit.

The top panel contains controls for switching the microphone on and off, for controlling listening level, and for signaling. They are easily identifiable by touch. A recessed, screwdriver-adjust control is provided for varying the level of the user’s voice to be heard in his own earphone (Sidetone). A long-life, extremely bright, 4-segment LED serves as the signal light. The bottom panel provides a 3-pin female XLR for connection to the system; a 3-pin male XLR for looping onwards to the next station, and; a 4-pin male XLR for connection of any standard communications headset with a dynamic microphone.

Durability: The ribbed, extruded aluminum case; glass-filled nylon end bezels; internal support system for the PC board; best-quality XLR-type connectors, and; recessed controls, all contribute to the outstanding ability of the BP-1 to withstand rough usage.

Value: The comparatively low price of the BP-1 is made possible by the minimized assembly cost resulting from simplicity of construction. Simple construction also affords the use of higher quality components, and increases the ease (thus lowering the cost) of servicing.

Compatibility: The BP-1 is plug-in compatible with Clear-Com® and other popular headset intercom systems

Pro Intercom SMH210 Single Muff Headset


Performance: Exceptionally high quality transducers provide wide smooth frequency response, reducing the onset of ‘ear fatigue’ for those who must spend many hours wearing headsets. Deep, comfortable ear cushions have excellent external noise exclusion characteristics, and are washable with ordinary dish washing detergent. At 7.35 oz. the SMH210, and at 8.75oz the DMH220, are much lighter than their appearances suggest. The noise-canceling microphone is mounted on a flexible, steel reinforced boom which can be easily twisted into a comfortable position. The flexible headband is adjustable. The normal transducer configuration for use with Pro Intercom and compatible headset intercom systems are 400ohm earspeakers and a 200ohm dynamic microphone. Electret microphones and lower impedance earspeakers for other applications are also available, and combinations of these transducers make up the various models. For use with Pro Intercom and most headset communications systems the SMH210 and DMH220 are fitted with a 4-pin female XLR-type plug. For other appliations many different plugs are available.

Durability: Because these headsets have only one moving part, and the microphone boom is flexible rather than hinged, a remarkable degree of durability is achieved. The light-weight cable consists of a copper shield around steel reinforced conductors, and is virtually unbreakable under normal circumstances. The assembly screws are hidden to prevent tampering. These headsets are easily field repairable. Pro Intercom maintains a full inventory of replacement parts at reasonable prices and provides fast turnaround on repairs.

Value: Low initial cost (compared to other professional communications headsets of equivalent quality), combines with long working life and low cost of repairs to offer outstanding value.

Compatibility: 200 series headsets are compatible with Clear-Com® and all other popular headset intercom systems, as well as drive-thru restaurant systems, disk jockey systems and other applications.

Pro Intercom PS4 AC Adapter Interface


The econoCom power supply, otherwise known as a PS4, is intended to be used in systems which require only one circuit. Up to 10 belt-packs may run on this system without creating hum or overheating the power supply. We recommend no more than two loudspeaker stations or stage manager stations however.

Requires EC Adapter sold separately
