4 Channel Mic-Level Microphone Mixer
Description
MLM-4 4 Channel Microphone Mixer for Surveillance and Audio Monitoring Systems
The MLM-4 4 Channel Microphone Mixer is a professional-grade surveillance audio mixer designed to power and combine the audio from up to four ETS ML1 series microphones into a single selectable line-level or mic-level output. Built for advanced monitoring applications, the MLM-4 allows installers to expand audio coverage across larger spaces or combine multiple surveillance zones into one recording channel.
Expand Audio Surveillance Coverage
The MLM-4 enables security professionals and integrators to connect and mix up to four surveillance microphones into one convenient output. This makes it ideal for:
- Expanding audio coverage in large rooms or open spaces
- Monitoring multiple zones simultaneously
- Integrating several microphones into one DVR or recording device
- Enhancing IP camera audio surveillance systems
When paired with the ETS SMEA-1, the MLM-4 provides expanded sound coverage for IP camera applications and other remote monitoring systems.
Flexible Audio Output Compatibility
The MLM-4 features a switch-selectable line-level or mic-level output, ensuring compatibility with a wide range of surveillance and recording equipment.
Features include:
- 3.5mm audio output jack for DVRs, recorders, and IP camera systems
- 3.5mm microphone input jacks for ML1 series microphones
- Optional –3.5MM or –FL (Flying Leads) output cable configurations
Independent Controls for Each Microphone
For maximum audio optimization, the MLM-4 includes dedicated controls for each channel:
- Independent volume controls for all four microphones
- Selectable low-cut filters to reduce unwanted low-frequency noise
- LED power indicator for quick system status verification
These features allow precise adjustment for different room acoustics and surveillance environments.
Reliable and Compact Design
Built for dependable long-term operation, the MLM-4 includes:
- Reverse polarity protection
- PPTC fused circuitry for enhanced safety
- Durable black ABS plastic enclosure
- Compact design for easy installation
Specifications:
- Power: 12–24VDC @ 20mA
- Dimensions: 4.3″ x 2.7″ x 1.6″
- Weight: 0.12kg

Application
Versatile Connectivity: The mixer is equipped with four microphone inputs, allowing you to connect up to four Sound Surveillance TM microphones simultaneously. Each microphone input is designed to power and mix the audio from the connected microphone.
Consolidated Output: The mixer combines the audio from all connected microphones into one unbalanced line level RCA output. This consolidated output makes it easy to connect the mixer to a recording device, amplifier, or other audio equipment for monitoring or recording purposes.
Expandable Coverage: By connecting multiple microphones to the mixer, you can expand the coverage of a single surveillance zone. This is particularly useful in large rooms, outdoor areas, or parking lots where a single microphone may not provide sufficient coverage.
Simultaneous Zone Monitoring: In addition to expanding coverage, the mixer enables you to monitor multiple zones simultaneously. By connecting microphones from different areas or rooms, you can mix the audio together and monitor all the zones from a central location.
Compact Design: The SMM-4 features a compact and space-saving design, making it easy to integrate into your surveillance setup. Whether mounted on a wall or placed on a desk, the mixer blends seamlessly into any environment.
Easy Installation and Operation: The mixer is designed for easy installation and operation. Simply connect the microphones to the designated inputs, adjust the levels as needed, and connect the output to your recording or monitoring device. The intuitive interface ensures hassle-free operation.
