Audix APS910 - Mini XLR to XLR Phantom Power Adapter and Preamplifier
The Audix APS910 is an indispensable professional component for sound engineers and musicians seeking maximum versatility and signal purity. This device is not a simple mechanical adapter; it is a high-precision active phantom power converter designed to manage the power and signal of electret condenser microphones. Its primary function is to allow the connection of lavalier, headset, hang mic, or instrument microphones that terminate in a female Mini XLR connector (commonly used in wireless systems) directly to a standard wired XLR microphone input.
Built to Audix's rigorous quality standards in the USA, the APS910 transforms the standard phantom power of mixers and preamps (ranging from 9V to 52V) into the low, stable bias voltage (approximately 2.5V) required by sensitive electret capsules. Simultaneously, it acts as an impedance converter and signal balancer, ensuring that audio travels over long cables without frequency loss or interference, preserving the microphone's original tonal integrity.
Its robust design is built to withstand the demands of live and studio use. Housed in a die-cast zinc alloy casing with a durable black E-coat finish, the APS910 offers exceptional durability. Furthermore, its gold-plated connectors ensure corrosion- and noise-free signal transfer, making this adapter a plug-and-forget solution for critical applications.
Main features
-
Intelligent voltage conversion: Accepts 9V to 52V phantom power and regulates it to safely power low-voltage electret capsules.
-
Low noise circuitry: Designed with precision electronics that minimize distortion (< 0.03%) and maximize the signal-to-noise ratio.
-
RF Immunity: Its metallic construction and circuit design protect the signal against radio frequency interference, crucial in environments saturated with wireless signals.
-
Premium Connectivity: Equipped with a 3-pin male Mini XLR input (for receiving the microphone) and a gold-plated standard male XLR output.
-
Heavy-Duty Construction: High-strength die-cast zinc chassis ideal for touring and heavy use.
Product benefits
-
Versatility of use: Allows the use of microphones that are normally intended for wireless systems (bodypacks) in wired configurations, saving the need for expensive receivers in static situations.
-
Superior audio quality: By connecting the microphone directly to the console via cable, compression and potential artifacts from wireless transmission are eliminated, resulting in the purest sound from the capsule.
-
Professional reliability: Eliminates the worry of dead batteries in wireless transmitters, as it is powered directly from the mixing console.
-
Full compatibility: Designed specifically to optimize the performance of Audix's ADX, Micro, and HT series, ensuring the correct frequency response curve.
Use cases
-
Studio recording of acoustic instruments: Use clip-on microphones such as the Audix MicroD or ADX10FL directly into a studio preamp to capture violins, flutes, or percussion with maximum fidelity.
-
Sound reinforcement in choirs and theaters: Ideal for fixed installations with hanging microphones (ADX40 series) where wired connection is preferable to wireless due to stability and cost.
-
Interviews and Broadcast: Connecting lavalier microphones directly to cameras or field recorders that supply phantom power via XLR.
-
Emergency backup: If a wireless system fails live, the APS910 allows you to connect the same headset or lavalier microphone using a standard XLR cable as an immediate solution.
Frequently Asked Questions
-
Does the APS910 require batteries to operate?
No, the APS910 is an active device that operates exclusively on phantom power (9-52V) supplied by the mixing console or audio interface. If you need a battery-powered model, you should look for the Audix APS911.
-
Can I use this adapter with microphones from other brands?
Although optimized for Audix microphones, it may work with electret microphones from other brands that use a 3-pin Mini XLR connector and have a compatible pinout (Pin 1: Ground, Pin 2: Signal/Bias). It is recommended to check your microphone's wiring diagram.
-
What type of connector does it have exactly?
The input is a 3-pin male Mini XLR connector (designed to receive the female connector of the microphone cable) and the output is a standard 3-pin male XLR connector (for connecting to the hose or table).
-
Does it affect the microphone sound?
The APS910 is designed for transparency. Its low-impedance, low-noise circuitry ensures the signal remains clean and true to the original source, often improving upon the quality of inexpensive wireless systems.
Project description
Phantom power adapter and in-line preamplifier for electret condenser microphones. The device must convert 9-52V DC phantom power to a 2.5V DC bias voltage. It must have a 3-pin male mini XLR input and a gold-plated standard male XLR output. Technical specifications include a frequency response of 20 Hz to 20 kHz, an output impedance of 200 Ohms, an input impedance greater than 50k Ohms, and a distortion level of less than 0.03% at 1 kHz. The construction must be of die-cast zinc alloy with a black E-coat finish resistant to RF interference. Approximate dimensions are 64 mm in length and 19 mm in diameter.
