Audix APS2 - 2-Channel Phantom Power Supply for Microphone (48V)
The Audix APS2 is the ultimate professional solution for integrating high-quality condenser microphones into any audio setup lacking native phantom power. Designed for absolute reliability in studios and on stage, this external power supply delivers a stable, noise-free 48 volts of DC power to two microphones simultaneously.
Many older mixers, portable recorders, and budget audio interfaces lack the power supply needed to operate the active circuitry of modern condenser microphones. The Audix APS2 solves this problem without compromising signal integrity. Unlike battery-powered solutions that can fluctuate and degrade audio as the charge runs down, the APS2 operates directly from mains power, ensuring a constant voltage and optimal microphone performance at all times.
Its robust metal chassis construction protects it against electromagnetic interference and the wear and tear of daily use on tours or in studios. Equipped with standard XLR connectors and a dual voltage switch, the APS2 is a versatile tool that meets the needs of discerning sound engineers and musicians looking to maintain the purity of their audio chain.
Main features
-
Dual Power Supply: Ability to power two condenser microphones simultaneously (or a stereo pair) with a stable 48V.
-
Constant Mains Power: Operates on alternating current (IEC cable included), eliminating dependence on batteries and ensuring that the voltage never drops during a critical recording.
-
International Voltage Switching: 110V/240V selector switch, allowing for use anywhere in the world (APS-2E model configured for European standards).
-
Low Noise Circuitry: Electronic design optimized to be transparent to audio, without introducing hiss or hum into the recording line.
-
Heavy-Duty Construction: Rugged metal casing designed to withstand the demands of live performance and protect internal components.
Benefits for the user
Adding the Audix APS2 to your audio setup frees you from the limitations of your mixing equipment. It allows you to use high-end studio microphones with simple live consoles or PA systems that were only designed for dynamic microphones. Its operation is "plug and forget": once plugged in, it provides a clean power platform that allows your microphones to operate at their maximum dynamic range and frequency response, just as the manufacturer intended.
Use cases
-
Home Studio: Ideal for connecting condenser microphones to older audio interfaces or sound cards that do not have a +48V switch.
-
Live Sound: Perfect for small venues or rehearsal setups where the mixing console is basic but quality microphones are required for vocals or acoustic instruments.
-
Location Recording: Useful for powering shotgun or ambient microphones when there is access to electrical power but the recording device (such as a camera or tape recorder) does not supply power.
-
Fixed Installations: Schools, churches or conference rooms where microphones are updated but the existing amplification system is maintained.
Frequently Asked Questions
Does the Audix APS2 affect the tone of my microphone?
No. The device is designed to be sonically transparent. Its sole function is to supply the necessary voltage without coloring or distorting the audio signal passing through it.
Can I use a dynamic microphone on the other channel if I'm only using a condenser microphone?
Yes. Phantom power does not damage modern balanced dynamic microphones. You can have a condenser microphone on channel 1 and a dynamic microphone on channel 2 without problems, although the dynamic microphone will simply ignore the current.
Does it need batteries to operate?
No, the APS2 is an AC powered unit and requires connection to a wall socket using a standard IEC power cable.
Does it work for ribbon microphones?
It depends on the microphone. Active ribbon microphones require phantom power and will work perfectly. For older (vintage) passive ribbon microphones, caution is advised, although most modern ones are protected.
Project description
This two-channel external phantom power supply is designed to deliver standard 48V DC to condenser microphones via balanced XLR connectors. The unit operates on AC power with a switchable voltage selector between 110V and 230V and is housed in a robust metal chassis with a dedicated power switch. It features two female XLR inputs and two male XLR outputs, offering low-noise signal transmission and compliance with international electrical standards.
