ST-MPA48

RDL ST-MPA48- Dual Microphone Phantom Adapter - 48V

The RDL ST-MPA48 is a dual-channel phantom power adapter designed to supply condenser microphones with a fixed 48V DC phantom voltage compliant with IEC 61938:2013 (P48). It converts standard mic inputs into phantom-powered inputs without affecting the signal path. Each of the two independent circuits includes a mic input and a mic output, with phantom voltage applied only to the input terminals, ensuring safe integration with existing mic preamps.

The ST-MPA48 operates from an external DC power source ranging from 10.5V to 26V, including 12V battery operation. Its internal filtering and regulation circuitry ensures clean and stable phantom power delivery for professional AV, sound reinforcement, and studio applications.

Functionality

• Converts standard mic inputs to 48V phantom-powered inputs
• Two independent phantom power circuits in one module
• Fixed 48V DC phantom voltage (P48, IEC 61938 compliant)
• No voltage present on mic output terminals
• Operates from external 10.5-26V DC power supply
• Internally filtered and regulated phantom power

Features

• Device type: dual microphone phantom power adapter
• Inputs/outputs: 2x mic input, 2x mic output (independent per channel)
• Phantom voltage: fixed 48V DC, IEC 61938 compliant
• Power supply: 10.5-26 V DC (ground-referenced)
• Operating temperature: 0°C to 55°C

RDL ST-MPA48 is a reliable and compact solution for AV integrators needing to add 48V phantom power to existing mic inputs. With wide power supply compatibility and high-quality filtering, it ensures safe and stable operation for condenser microphones in demanding environments.
