Inline Phantom Power Adapter for Electret Microphones
The Audix APS910 is an inline phantom power adapter designed to safely power electret microphones using standard mixer or preamp phantom power. It converts 9–52 volts of phantom power from a conventional XLR input into the correct operating voltage required by miniature electret microphones. This makes the APS910 an essential accessory when connecting lavalier, headset, hanging, or boundary microphones to professional audio consoles and interfaces.
Designed to Bridge Mini XLR Microphones with Pro Audio Gear
The APS910 functions as a clean and reliable interface between microphones equipped with mini XLR connectors and standard XLR microphone inputs. One end features a mini XLR connection for compatible electret microphones, while the other end provides a full-size XLR connector for connection to a mixer, audio interface, or microphone cable. This design allows smaller microphones to integrate seamlessly into professional sound systems without additional power supplies.
Safe Phantom Power Conversion for Electret Microphone Operation
Electret microphones require lower and more precisely routed power than standard condenser microphones. The APS910 takes incoming phantom power and ensures it is delivered correctly to the microphone, protecting sensitive components while maintaining proper performance. This controlled power adaptation supports consistent microphone operation, stable signal output, and long-term reliability in both studio and installed sound environments.
Ideal for Installed Sound and Portable Audio Setups
This phantom power adapter is commonly used in conference rooms, houses of worship, classrooms, broadcast setups, and live production environments. It eliminates the need for dedicated external power modules when phantom power is already available at the console. For mobile rigs and fixed installations alike, the APS910 simplifies wiring and reduces clutter while ensuring compatible microphones receive proper power.
Compatible with a Wide Range of Audix Electret Microphones
The APS910 is designed to work with several Audix miniature microphone models, including lavalier, headset, hanging, and boundary-style microphones. This broad compatibility makes it a versatile solution for users who deploy multiple microphone types across different applications. It is especially useful for systems that rely on compact microphones paired with standard professional audio infrastructure.
Compact Inline Design for Easy Integration
With its inline form factor, the APS910 fits easily into existing signal chains without adding bulk or complexity. It can be placed directly at the microphone input or along the mic cable run, making it flexible for both permanent installations and temporary setups. Its straightforward design ensures dependable operation with minimal configuration.
