Four Channel Interface Adapter with Volume Control
Description
SMI-4L Four Channel Microphone Interface Adaptor with Level Controls
The SMI-4L Four Channel Microphone Interface Adaptor is a professional surveillance audio interface designed to power and distribute audio from up to four ETS SM1 series microphones. Engineered for seamless integration with DVRs, CCTV systems, remote monitoring equipment, and line-level audio devices, the SMI-4L delivers reliable multi-channel audio management in a compact and easy-to-install solution.
Four Independent Audio Channels
The SMI-4L powers up to four ETS SM1 microphones and routes each microphone to its own dedicated output connection. This allows installers to monitor or record multiple surveillance zones independently while maintaining clean, organized audio distribution.
Ideal for:
- Multi-camera surveillance systems
- DVR and NVR audio integration
- Remote monitoring applications
- CCTV systems with built-in speakers
- Commercial and industrial security installations
Designed for Surveillance Audio Systems
Built specifically for use with equipment featuring unbalanced line-level inputs, the SMI-4L integrates easily into existing surveillance infrastructures.
Features include:
- Individual RCA audio outputs
- Optional 3.5mm output jack configuration
- Compatibility with DVRs, CCTV monitors, and audio recording systems
- Optimized for ETS SM1 series microphones
Adjustable Level Controls for Optimized Audio
The integrated level controls allow installers to fine-tune audio output levels for each microphone channel, helping ensure balanced, distortion-free sound quality across all connected devices.
Benefits include:
- Improved voice clarity
- Better audio balancing between zones
- Enhanced recording quality
- Flexible integration into different monitoring systems
Compact and Reliable Design
The SMI-4L is engineered for dependable long-term performance in professional security and surveillance environments. Its compact footprint makes installation simple in equipment racks, monitoring stations, and surveillance cabinets.
