Motorola PMMN4136A Mic for APX Next

Motorola PMMN4136B XVP830 IMPRES Remote Speaker Microphone

The Motorola PMMN4136B XVP830 Remote Speaker Microphone is a rugged, mission-critical audio accessory built for select Motorola APX and APX NEXT portable radios. Its four high-dynamic-range microphones, adaptive noise suppression, powerful 47 mm speaker and IP68-rated housing help public-safety professionals communicate clearly in severe weather and high-noise environments.

Designed without a channel-selection knob, the PMMN4136 offers a streamlined control layout for users who change channels directly from their radio. It retains the premium audio processing, emergency control, programmable buttons and hazardous-location capability found in Motorola’s advanced XVP microphone family.

PMMN4136B Specifications

Specifications are based on Motorola Solutions’ official XVP remote speaker microphone datasheet.

Compatible Motorola Radios

Motorola lists the PMMN4136 XVP830 for use with the following radios:

• Motorola APX 6000
• Motorola APX 6000XE
• Motorola APX 8000
• Motorola APX 8000XE
• Motorola APX 8000H
• Motorola APX 8000HXE
• Motorola SRX 2200

Firmware Requirements

Motorola specifies the following minimum firmware levels:

• Compatible APX radios: R24.00.00 or later
• APX NEXT radios: R03.20.00 or later

Radio compatibility and advanced features can depend on firmware, programming, connector configuration and regional certification. Confirm the complete radio model and firmware version before ordering.

Advanced Four-Microphone Noise Suppression

The PMMN4136B uses four high-dynamic-range microphones positioned around the microphone housing. This arrangement provides voice pickup from multiple directions and helps reduce the muffled sound that can occur when a remote speaker microphone is held or worn in different positions.

Its adaptive noise-suppression algorithm tracks the user’s voice while filtering changing background noise. This makes the XVP830 particularly useful around:

• Fire engines and emergency vehicles
• Sirens and warning systems
• Heavy machinery
• Construction equipment
• Large crowds
• Strong wind
• Industrial operations
• High-noise emergency scenes

HDR microphone technology also helps prevent voice distortion when personnel shout in extreme conditions.

Loud, Intelligible Speaker Audio

A remote speaker microphone must be loud enough to hear without sacrificing speech clarity. The PMMN4136 incorporates a large 47 mm speaker engineered to produce approximately 105 phons at a distance of 12 inches when used with supported equipment.

The microphone works with the adaptive audio capabilities of compatible APX and APX NEXT radios. Adaptive microphone gain, speaker equalization and noise suppression work together to improve transmitted and received speech.

Compatible APX NEXT configurations may also support Receive Volume Leveling, which automatically compensates for unusually loud or quiet received voices.

Streamlined Controls Without a Channel Knob

The Motorola PMMN4136 is designed for users who want premium XVP performance without a channel knob on the microphone. Channels are selected from the connected radio, reducing the possibility of accidentally changing the channel from the shoulder-mounted microphone.

Available controls include:

• Top orange emergency button
• Volume-up and volume-down buttons
• Protected side push-to-talk button
• Two side programmable buttons
• One front programmable ViQi button

The front programmable button can activate Motorola ViQi voice control when ViQi Assistant is installed and properly configured on the radio.

IP68 and Work-When-Wet Protection

The PMMN4136B carries an IP68 environmental rating. Motorola rates it for protection against dust and submersion in two meters of water for up to four hours under specified test conditions.

Its Work-When-Wet design allows the microphone to continue functioning after water exposure. Windporting openings also help redirect airflow and drain water away from the microphones.

The XVP830 is tested to applicable MIL-STD-810H procedures addressing:

• Rain
• Salt fog
• Blowing dust
• Vibration
• Mechanical shock

These protections make the PMMN4136 well suited for law enforcement, firefighting, emergency medical services, utilities, military operations and industrial response teams.

Intrinsically Safe and HazLoc Capability

The PMMN4136 XVP830 family is available with intrinsic-safety approval for qualifying hazardous-location configurations. Motorola’s published classifications include:

• Division 1, Class I, Groups C and D
• Division 1, Class II, Groups E, F and G
• Division 1, Class III
• Division 2, Class I, Groups A, B, C and D
• Division 2, Class II, Groups F and G
• Division 2, Class III

Hazardous-location approval applies to the complete system—not the microphone alone. The radio, battery and microphone must be approved for use together. Verify the precise PMMN4136 suffix and certification label before use in a hazardous atmosphere.

Motorola PMMN4136 Alternative Options

PMMN4136 vs. PMMN4135

The PMMN4135 XVP850 is the closest alternative to the PMMN4136. Both microphones provide four-microphone noise suppression, a loud 47 mm speaker, IP68 protection, programmable controls, IMPRES audio and HazLoc capability in approved configurations.

The primary operational difference is channel control:

• Choose the PMMN4136 XVP830 when channels will be selected from the radio.
• Choose the PMMN4135 XVP850 when users need a channel knob on the microphone.

PMMN4136 vs. PMMN4142

The PMMN4142 XVP730 is another no-channel-knob alternative. It provides the modern XVP form factor, four-microphone audio processing and a dedicated ViQi button for supported radio configurations.

Choose the PMMN4136 when an approved HazLoc configuration or compatibility with the specified legacy APX models is required. Consider the PMMN4142 for compatible APX N-series applications where those requirements do not apply.

Optional Earpiece and Replacement Parts

Compatible secondary accessories and replacement parts include:

The PMLN8120 connects to the PMMN4136’s 3.5 mm jack and routes received audio to the user’s ear for greater privacy. Transmit audio continues to pass through the speaker microphone.

Best Uses for the Motorola PMMN4136B

The XVP830 is particularly suitable for:

• Police and sheriff’s departments
• Fire and rescue operations
• Emergency medical services
• Military and federal agencies
• Utility crews
• Petrochemical facilities
• Industrial emergency-response teams
• Transportation and public-works departments
• Personnel working around machinery or severe background noise

Why Buy the Motorola PMMN4136B?

Choose the Motorola PMMN4136B when clear voice communication, extreme durability and simplified controls are essential. Its four-microphone array actively reduces changing environmental noise, while the large speaker produces loud, intelligible received audio.

Because the XVP830 does not include a channel knob, it is especially appropriate for departments that want users to change channels only from the radio. Its IP68 construction, Work-When-Wet performance, emergency controls and approved HazLoc configurations make it a strong solution for demanding public-safety operations.
