The Samson MDA1 Mono Active Direct Box brings professional-grade signal processing to musicians who demand pristine audio quality in both live and studio environments. This active DI box operates on either batteries or phantom power, ensuring reliable performance whilst maintaining clean, balanced signal transmission from guitars and basses to mixing consoles and recording equipment.
Built with premium sound circuitry, the MDA1 provides consistent frequency response across all connected audio signals, regardless of their output impedance characteristics. This makes it particularly valuable for instruments with passive pickups and high impedances, as it preserves the crucial top-end frequencies that define your instrument's tonal character. The balanced output significantly reduces noise interference compared to unbalanced connections, allowing for extended cable runs without signal degradation. A convenient 2-position attenuation switch (0dB/-15dB) adapts the unit to accommodate various signal levels.
The integrated Thru jack offers practical signal splitting capabilities, allowing you to send your instrument's signal simultaneously to the mixing console and your amplifier or stage monitor. This feature proves especially useful in modern live sound applications where in-ear monitoring systems are increasingly common, potentially eliminating the need for traditional amplifier miking techniques whilst maintaining your preferred stage sound.
Constructed within a robust 14-gauge steel chassis, the MDA1 withstands the rigours of professional touring and heavy studio use. The reinforced outer shell protects all internal components, switches, and solder joints from mechanical stress and environmental factors, ensuring consistent, quiet operation throughout its service life.
