Compatible Motorola Radios
| Motorola radio | Compatibility | Important Notes |
| APX N70 | Yes | Requires radio firmware R01.00.00 or later |
| APX N70 XE | Yes | Use an approved radio, battery and RSM combination when HAZLOC certification is required |
| APX N50 | Conditional | May require the appropriate Audio Bundle/configuration; verify before ordering |
| APX N30 | Not listed as a standard XVP730 application | Consider an RM760 or RM780 designed for the N30/N50 platform |
| APX NEXT | No | Uses the XVP830 or XVP850 platform |
| APX 6000/8000 | No | Use the compatible XVP830/XVP850 or approved XVE-series microphone |
The PMMN4142A uses Motorola’s newer mini-GCAI connector and should not be selected based only on the appearance of a radio’s accessory port. Confirm the radio model and configuration before purchase.
Four-Microphone Adaptive Noise Suppression
The XVP730 uses four HDR microphones and sophisticated audio-processing algorithms to locate the user’s voice and suppress surrounding noise. Unlike a conventional single directional microphone, the PMMN4142A can deliver intelligible audio from different speaking angles.
This design is particularly valuable during:
- Police and tactical operations
- Fire and emergency response
- Traffic control
- Public events
- Severe weather
- Industrial operations
- High-noise public-safety assignments
- Situations where the user cannot precisely position the microphone
Exceptionally Loud Receive Audio
The integrated speaker produces up to 105 phon at 12 inches, helping users hear incoming radio traffic in loud environments. Receive Volume Leveling can also help balance transmissions from callers speaking at different volumes when supported and enabled by the connected radio.
Actual loudness and available audio features depend on radio programming and system configuration.
Rugged IP68 and Work-When-Wet Design
The Motorola PMMN4142A carries an IP68 rating and is tested for submersion in up to two meters of water for as long as four hours under defined conditions. Its work-when-wet design helps maintain communication after exposure to rain or water.
The RSM is also tested for environmental stresses that include:
- Rain
- Dust
- Salt fog
- Vibration
- Shock
- Extreme operating temperatures
IP68 does not guarantee protection against every chemical, liquid or physical condition. Covers, cables and connectors must be properly secured and maintained.
HAZLOC Capability
The PMMN4142A is designed for approved hazardous-location configurations and supports Division 1 and Division 2 applications when used with the correct Motorola radio, battery and accessories.
The microphone alone does not make a radio intrinsically safe. HAZLOC users must confirm that the complete configuration is approved for the classification required at their facility.
Essential Controls Within Easy Reach
The PMMN4142A enables users to operate important radio functions without removing the portable radio from its holster. Available controls include:
- Large push-to-talk button
- Orange emergency button
- Dedicated ViQi button
- Three programmable buttons
- Volume control
Button functions depend on the connected radio’s programming and enabled features.
No-Channel-Knob Design
The XVP730 does not have a channel knob. This streamlined design reduces bulk and helps prevent accidental channel changes during tactical movement, vehicle entry or physically demanding assignments.
Users who need channel selection directly from the microphone should consider the Motorola PMMN4141A XVP750, which offers similar core features with an integrated channel knob.
PMMN4142A vs. PMMN4141A
| Feature | PMMN4142A XVP730 | PMMN4141 AXVP750 |
| Four-microphone noise suppression | Yes | Yes |
| IMPRES audio | Yes | Yes |
| IP68 | Yes | Yes |
| 3.5mm audio jack | Yes | Yes |
| Emergency and programmable buttons | Yes | Yes |
| ViQi button | Yes | Yes |
| Channel-selection knob | No | Yes |
| Best application | Preventing accidental channel changes | Selecting channels from the RSM |
Choose the PMMN4142A when the radio channel is normally selected before deployment or accidental channel changes are a concern. Choose the PMMN4142A when users need channel control on the shoulder microphone.
Private Listening with a Receive-Only Earpiece
A 3.5mm non-threaded audio jack allows a compatible Motorola receive-only earpiece to be connected for private incoming audio. This can be useful during surveillance, public-facing assignments and operations where radio traffic should not be broadcast through the external speaker.
Verify earpiece compatibility before ordering. Standard consumer earbuds may not provide the correct fit, retention or professional performance.
Why Choose the Motorola PMMN4142A?
The PMMN4142A is an excellent choice for APX N70 users who need:
- Advanced noise suppression
- Loud, intelligible receive audio
- Reliable communication from multiple speaking angles
- IP68 environmental protection
- HAZLOC capability
- Emergency and programmable controls
- ViQi access
- Private-listening compatibility
- Protection against accidental channel changes
