Motorola PMMN4059B Public Safety Microphone (IS): PMMN4059, PMMN4059A

Motorola PMMN4059B IMPRES Public Safety Microphone – 18-Inch Cord

The Motorola PMMN4059B IMPRES Public Safety Microphone gives public-safety and professional radio users convenient shoulder-mounted access to push-to-talk communication, received audio and essential radio controls. Its compact 18-inch straight cord makes it an excellent choice when the radio is carried near the shoulder or upper torso and excessive cable length is undesirable.

The PMMN4059B combines Motorola IMPRES audio technology, Windporting, a programmable orange emergency button, volume control, a 3.5mm audio jack and an external public-safety microphone antenna connection. Its rugged, weather-resistant construction is designed for law enforcement, emergency response, security, utility and other demanding field operations.

A compatible public-safety microphone antenna is required and is generally sold separately. Always verify the radio model, frequency band, antenna and accessory connector before ordering.

PMMN4059B Features and Benefits

Compact 18-Inch Straight Cord

The PMMN4059B uses an 18-inch straight cord, making it the shortest-cord option among the comparable PMMN4059B, PMMN4060B and PMMN4061B public-safety microphones.

The shorter cable is particularly useful when:

• The radio is mounted high on a tactical vest

• The radio is carried in an upper-body harness

• The distance between the radio and shoulder microphone is limited

• Reducing loose or excess cable is important

• A clean, close-fitting equipment arrangement is preferred

Users carrying a radio on a waist-level duty belt or beneath heavy body armor may prefer the longer PMMN4060B or PMMN4061B.

Motorola IMPRES Audio

Motorola IMPRES audio technology allows a compatible radio to recognize the attached microphone and apply appropriate audio parameters. This helps maintain consistent, intelligible communication in demanding environments.

The available IMPRES functions depend on the radio model, programming and system configuration.

Windporting Technology

Motorola Windporting technology helps reduce wind noise passing across the microphone opening. It also helps prevent water from obstructing the microphone port, supporting clearer transmissions during rain, traffic control, motorcycle patrols and outdoor assignments.

Public-Safety Microphone Antenna Connection

Unlike a conventional remote speaker microphone, the PMMN4059B includes a connection for a compatible public-safety microphone antenna. Relocating the antenna from a belt-mounted radio to the shoulder microphone can position it higher on the user’s body and reduce obstruction from clothing or equipment.

The antenna must match the radio’s frequency band. An incorrect antenna can reduce communication performance or prevent the system from operating properly.

Programmable Emergency Button

The prominent orange emergency button provides fast access to supported emergency functions. Its exact operation depends on radio programming and whether the applicable emergency feature is enabled on the radio system.

Integrated Volume Control

A microphone-mounted volume control lets the user adjust received audio without reaching for a radio carried under clothing, on a belt or in a protective case.

3.5mm Audio Jack

The 3.5mm non-threaded audio jack accepts a compatible receive-only earpiece, allowing incoming radio traffic to be heard more discreetly. The earpiece is sold separately.

IP55 Environmental Protection

The PMMN4059B is commonly specified with an IP55 environmental rating, providing protection against limited dust intrusion and water jets under controlled test conditions.

IP55 does not mean the microphone can be submerged. Verify the rating printed on the product and its documentation before deployment.

Compatible Motorola Radios

The PMMN4059B is commonly listed for supported configurations within the Motorola APX and SRX radio families, including:

• Motorola APX 6000

• Motorola APX 6000Li

• Motorola APX 6000XE

• Motorola APX 7000

• Motorola APX 7000XE

• Motorola APX 8000

• Motorola APX 8000XE

• Motorola SRX 2200

Compatibility may depend on the radio’s exact model, frequency band, connector and firmware or system configuration. Confirm the model number on the radio and the required PSM antenna before purchasing.

Motorola PMMN4059B Specifications

PMMN4059B vs. PMMN4060B vs. PMMN4061B

The principal difference among these Motorola public-safety microphones is their cord length. Selecting the right model depends primarily on where the radio is carried in relation to the shoulder microphone.

Choose the PMMN4059B When:

Choose the PMMN4059B 18-inch microphone when the radio is mounted relatively close to the shoulder microphone and minimizing excess cable is the priority. It is generally best suited to tactical vests, upper-body harnesses and compact equipment arrangements.

Choose the PMMN4060B When:

Choose the Motorola PMMN4060B 24-inch public safety microphone when you need additional routing room between a shoulder-mounted microphone and a belt- or vest-mounted radio. Its intermediate cord length provides a balance between reach and cable management.

Choose the PMMN4061B When:

Choose the Motorola PMMN4061B 30-inch public safety microphone when the radio is worn lower on the body, beneath protective clothing or around substantial body armor. Its longer cord provides the greatest routing flexibility.

Do not select between these microphones by cord length alone. Confirm the radio model, frequency band, compatible PSM antenna, connector and certification requirements before ordering.

PMMN4059B vs. a Standard Remote Speaker Microphone

The PMMN4059B is a stronger choice when the user needs an external antenna connection and microphone-mounted controls. A conventional speaker microphone may be preferable when an external PSM antenna is unnecessary.

Best Uses for the PMMN4059B

The Motorola PMMN4059B is well suited for:

• Police officers using tactical vests

• Emergency-response personnel

• Security and critical-infrastructure teams

• Utility and public-works crews

• Motorcycle and traffic-enforcement units

• Outdoor personnel working around wind and rain

• Users who prefer minimal excess microphone cable

• Radio configurations with a short distance between the radio and shoulder microphone

Important Antenna Notice

The PMMN4059B requires a compatible public-safety microphone antenna. The antenna is normally sold separately and must match the radio’s operating frequency.

Do not automatically use the antenna from the radio or assume that one antenna works with every APX configuration. Confirm the appropriate antenna before placing the microphone into service.

Intrinsic-Safety and HAZLOC Notice

Do not assume the PMMN4059B is approved for hazardous-location use solely because a seller describes it as “intrinsically safe.”

Hazardous-location eligibility can depend on the exact product revision and the approved combination of radio, battery, microphone and antenna. Verify the certification label and applicable Motorola documentation before using this microphone around flammable gases, vapors, combustible dust, fuels or ignitable fibers.

Frequently Asked Questions

How long is the PMMN4059B cord?
