Let the Matchbox-HD 4-Channel Stereo RCA to XLR Audio Interface revolutionize your audio experience. This innovative and reliable audio converter, designed by the reputable Henry Engineering, is the perfect solution for professional audio applications that require RCA to XLR signal conversion.
The Matchbox-HD is not just an audio interface; it's a high-quality, bi-directional stereo level and impedance interface that seamlessly bridges the gap between consumer gear and professional equipment. It's designed to eliminate common audio issues such as hum, buzz, and distortion caused by mismatched levels and impedances.
Ideal for devices that both play and record, like DAT recorders and computer sound cards, the Matchbox-HD stands out from other audio interfaces. It doesn't rely on inexpensive "wall-warts" for power but instead features an internal AC power supply, ensuring consistent, high-quality performance.
The Matchbox-HD is more than just a durable piece of equipment; it's a testament to superior audio performance. It boasts a true 100 dB S/N ratio, with 22 dB of headroom, providing an impressive 122 dB of dynamic range. This ensures that your audio is not just heard, but experienced in its fullest, richest form.
This user-friendly audio interface is a bi-directional unit, employing four independent amplifiers to convert stereo inputs and outputs from unbalanced -10 dBv levels to +4 dBm balanced 600 ohm lines. All four outputs can be adjusted to accommodate a wide range of operating levels, providing you with the flexibility you need for various audio applications.
The Matchbox-HD also features a special HI GAIN mode, specifically designed to match the low-level unbalanced outputs of computer sound cards. Its direct-coupled circuitry and exceptional dynamic range ensure absolute sonic transparency, making it an ideal choice for use with digital editors, DAT recorders, and other digital audio sources.
With its 1/3 rack width, the Matchbox-HD can be conveniently mounted using an optional rack shelf or wall-mounted with optional wall/cabinet mounting brackets. Experience the difference of high-quality, professional audio conversion with the Matchbox-HD 4-Channel Stereo RCA to XLR Audio Interface.
