Motorola PMMN4099A IMPRES APX Speaker Mic – IP55

Motorola PMMN4099A IMPRES Remote Speaker Microphone for APX Radios

The Motorola PMMN4099A IMPRES Remote Speaker Microphone provides powerful, intelligible audio and convenient shoulder-mounted controls for compatible Motorola APX portable radios. Designed for police, emergency-response, security, utility and industrial users, this genuine Motorola speaker mic combines IMPRES audio, Windporting technology, an emergency button, high/low volume toggle, 3.5mm accessory jack, rotating clothing clip and IP55 environmental protection.

The PMMN4099A allows users to transmit, hear radio traffic, change the speaker volume and activate supported emergency functions without removing the radio from a duty belt, protective case or tactical vest. Its large, glove-friendly housing makes it especially practical for public-safety personnel and field workers operating in demanding environments.

Unlike Motorola public-safety microphones with external antenna connections, the PMMN4099A is a standard remote speaker microphone. It uses the antenna installed on the radio and does not require a separate PSM antenna.

Motorola PMMN4099A Features and Benefits

Motorola IMPRES Audio

Motorola IMPRES technology allows the PMMN4099A and a compatible APX radio to communicate electronically and apply appropriate audio parameters. This helps optimize microphone sensitivity and speaker output for more consistent audio performance.

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

Windporting Technology

Motorola Windporting technology helps reduce wind noise moving across the microphone opening. It also helps prevent water from obstructing the microphone port, supporting clearer voice transmission during traffic control, outdoor patrol, severe weather and other exposed working conditions.

The PMMN4099A is an excellent choice for users working around:

• Wind and severe weather

• Roadside traffic

• Emergency vehicles

• Outdoor utility equipment

• Construction sites

• Marine and waterfront environments

• Large outdoor facilities

Loud, Intelligible Speaker Audio

The PMMN4099A uses a high-output speaker designed for the Motorola APX platform. It delivers strong received audio for personnel working in noisy public-safety and industrial environments.

Motorola has described compatible APX audio accessories as providing clearer, more intelligible audio and output up to 50% louder than earlier XTS-series remote speaker microphones. Actual perceived volume depends on radio settings, background noise and microphone placement.

High/Low Volume Toggle

The integrated high/low volume toggle lets users quickly adjust the microphone’s received audio without reaching for the radio.

The high setting is useful around traffic, machinery and emergency scenes. The lower setting is better suited to offices, hospitals, nighttime operations and quieter environments.

Programmable Emergency Button

The PMMN4099A includes an accessible emergency button that can activate supported emergency features without requiring the user to reach for the portable radio.

The button’s exact operation depends on the radio programming and system configuration.

3.5mm Audio-Accessory Jack

A 3.5mm accessory port accepts a compatible receive-only earpiece for more discreet incoming communications. The earpiece is sold separately.

Verify the earpiece plug and accessory compatibility before ordering.

Rotating Clothing Clip

The rotating swivel clip lets the user position the speaker microphone on a uniform, tactical vest, jacket or shoulder strap. Adjusting the clip helps keep the microphone upright and accessible while reducing cable interference.

Large, Glove-Friendly Housing

The PMMN4099A has a large microphone head and accessible controls that are easier to locate and operate while wearing gloves. This is particularly useful for police, fire-support personnel, utility workers and industrial teams.

IP55 Environmental Protection

The Motorola PMMN4099A carries an IP55 rating, providing protection against limited dust intrusion and water jets under defined testing conditions.

IP55 does not mean the microphone is waterproof or submersible. Inspect the microphone housing, cable and radio connector regularly when used in wet or demanding environments.

Compatible Motorola APX Radios

Radio revisions, connectors and regional configurations can vary. Confirm the exact radio model and accessory compatibility before ordering.

Compatibility and certification can vary by radio configuration. Confirm each microphone against the exact radio model before ordering.

PMMN4099A vs. a Basic Speaker Microphone

The PMMN4099A is the stronger option when users need Motorola IMPRES audio, convenient volume control, an emergency button and better weather protection.

Best Uses for the PMMN4099A

The Motorola PMMN4099A is well suited for:

• Police and law-enforcement patrol

• Traffic-control and motorcycle units

• Emergency-response personnel

• Security and critical-infrastructure teams

• Utility and public-works crews

• Transportation and logistics operations

• Industrial and manufacturing facilities

• Outdoor personnel working around wind and rain

• Users who wear work gloves

• Personnel who need fast high/low volume adjustment

• APX users who do not need an external microphone antenna

Important HAZLOC and Intrinsic-Safety Notice

Do not assume the PMMN4099A is approved for hazardous-location use unless the product’s physical certification label and Motorola documentation expressly identify the required approval.

Hazardous-location eligibility may depend on the exact microphone revision and its approved combination with a radio and battery. An IP55 rating indicates environmental protection; it does not establish intrinsic-safety or HAZLOC approval.

Frequently Asked Questions

What radios work with the Motorola PMMN4099A?

The PMMN4099A is commonly listed for supported Motorola APX 1000, APX 3000, APX 4000, APX 6000, APX 7000 and APX 8000 configurations, along with the SRX 2200. Verify the complete radio model before ordering.

Is the PMMN4099A an IMPRES microphone?

Yes. The PMMN4099A supports Motorola IMPRES audio technology with compatible APX radios.

Does the PMMN4099A have volume control?

Yes. It includes a high/low volume toggle that allows users to quickly change the microphone’s received-audio level.

Is the PMMN4099A noise canceling?

The PMMN4099A’s prominently identified weather-audio feature is Windporting, which helps reduce the effects of wind around the microphone opening. Customers specifically needing noise-canceling microphone acoustics should compare it with the PMMN4062A.

Does it require a separate antenna?

No. The PMMN4099A uses the antenna installed on the radio. It does not require the separate PSM antenna used by the PMMN4059B, PMMN4060B and PMMN4061B.
