Its 1 MΩ input is particularly suitable for guitars and basses with passive pickups, which can lose high-frequency detail when connected to an input with insufficient impedance.\u003c\/p\u003e\n\u003cp\u003eThe 1\/4-inch TS Input accepts the source, while the parallel Thru jack keeps a stage amplifier or monitor connected to the same signal. A balanced XLR output feeds a microphone input on a mixing console, audio interface, recorder, or stage box over a low-impedance balanced cable.\u003c\/p\u003e\n\u003cp\u003eThe MDA1 can run from 48 V phantom power through the XLR connection or from one 9 V battery. When phantom power is present, the circuit selects it and disconnects the battery. Removing the cable from the Input turns off the battery circuit so the cell is not drained while the DI box is idle.\u003c\/p\u003e\n\u003cp\u003eA 0 dB\/-15 dB pad provides headroom for higher-level sources. Ground Lift disconnects XLR pin 1 when a ground loop introduces hum. The electronics are protected by a 14-gauge steel chassis. A 9 V battery is required when phantom power is unavailable and is not included.\u003c\/p\u003e\n\u003ch3\u003eMain Features\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003eActive circuit with a 1 MΩ input suits passive guitar and bass pickups.\u003c\/li\u003e\u003cli\u003eParallel Thru output keeps a stage amplifier or monitor connected to the source.\u003c\/li\u003e\u003cli\u003eRuns from 48 V phantom power or one 9 V battery.\u003c\/li\u003e\u003cli\u003eSelectable 0 dB\/-15 dB pad accommodates higher input levels.\u003c\/li\u003e\u003cli\u003eGround Lift helps address hum caused by a ground loop.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003e\u003cstrong\u003eType:\u003c\/strong\u003e mono active direct box\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 18 Hz to 35 kHz, -3 dB\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eMaximum input:\u003c\/strong\u003e +2 dBu with a 9 V battery\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eGain:\u003c\/strong\u003e +4.8 dB\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDynamic range:\u003c\/strong\u003e 105 dB at the balanced output\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eNoise floor:\u003c\/strong\u003e -98 dB with the pad off\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eTotal harmonic distortion:\u003c\/strong\u003e less than 0.05% from 18 Hz to 35 kHz\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eInput impedance:\u003c\/strong\u003e 1 MΩ\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eOutput impedance:\u003c\/strong\u003e 200 Ω\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eInput pad:\u003c\/strong\u003e 0 dB\/-15 dB\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eConnections:\u003c\/strong\u003e 1\/4-inch TS Input and Thru, balanced 3-pin XLR output\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003ePower:\u003c\/strong\u003e 48 V phantom power or one 9 V battery\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e 14-gauge steel chassis\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 127 × 86 × 50 mm\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eProduct weight:\u003c\/strong\u003e 611 g\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\u003cul\u003e\u003cli\u003eSamson MDA1 mono active direct box\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch3\u003eWho Is It For\u003c\/h3\u003e\n\u003cp\u003eThe MDA1 is intended for guitarists, bassists, studios, and live sound technicians who need to send a high-impedance instrument signal to a console over a longer balanced XLR cable without loading down passive pickups.
