Because professional audio quality matters, the Sonifex RB-MA1 Single Microphone Amplifier is expertly designed to deliver high-quality, reliable audio amplification. This durable microphone amplifier is equipped with a low-noise pre-amplifier, adept at converting mic level signals to line level, or driving long lines from microphones to mixing equipment, making it a versatile choice for both studio and video settings.
The RB-MA1 boasts a high frequency response of 20Hz to 20kHz, ensuring it can handle a broad spectrum of audio signals. Its low impedance of 2kOhm input and less than 50Ohm output makes it compatible with a wide array of microphones and audio equipment, enhancing its versatility.
All connections and controls are conveniently located on the rear panel for easy access. The microphone input is an XLR-3 type and is electronically balanced, accommodating both dynamic and powered microphones. The gain for the input can be finely adjusted by a recessed pre-set potentiometer, allowing for precise control over your audio output.
The line output, also an XLR-3 type, is electronically balanced and can be wired unbalanced by grounding the non-phase signal. This feature enables you to feed both balanced and unbalanced equipment, further enhancing its adaptability.
Additionally, the RB-MA1 comes with a switch to control a high pass filter, offering low frequency roll-off at 125Hz. It also provides phantom power at +48V to the connected microphone, ensuring optimal performance. With the Sonifex RB-MA1 Single Microphone Amplifier, you're investing in professional, high-quality audio amplification.
