Passive Direct Box

High-quality passive interface lets you connect instrument, line, or speaker level signals to a mixer or other balanced input. High impedance, single-ended (unbalanced) 1/4" input is converted into an isolated, balanced low impedance signal source. The internal audio transformer has extremely flat and wide frequency response and can handle high signal levels.

Product Description

Input-attenuator switches allow selection of 0dB, -20dB or -40dB for a wide range of signal levels and the input-thru jack allows tapping off of the signal chain. The ground-lift switch separates input and output signal grounds to isolate two systems, reducing hum and ground-loop noise.

  • Switchable 30KHz low-pass bessel filter to cut out high frequency RF and electrical interference
  • Phase invert switch
  • Compact black anodized aluminum case
  • Frequency response: 10Hz~50KHz
  • THD: 0.01%
  • Input and input-thru connection: 1/4" unbalanced, 50Kohm
  • Output connection: XLR male, 600ohm
  • Dimensions: 1.75" (H) x 4.2" (W) x 3.5" (D)
