Capitalizing on decades of design celebrated by musicians and sound engineers, the SES-DIPRO Passive DI Box from Sescom is a versatile, passively operated DI box that converts a high-impedance, unbalanced, line-level signal to a low-impedance, balanced, microphone-level signal, with three selectable levels of attenuation: -20, -40, and -60 dB. Utilizing high-fidelity circuitry for optimal sound quality, the DIPRO sports one combo XLR-1/4" jack for input, one Neutrik XLR male jack for output, and one 1/4" loop out for monitoring your unaffected signal with an amplifier or loudspeaker, and can send balanced signals too via TRS cables.
