ART PDB4 Rackmountable 4-Channel Passive Direct Box

Four-Channel Passive Direct Box The PDB4 is a four channel passive direct box that features four quality fully transformer isolated direct boxes in a 1U 19-inch rack mount chassis. Inputs and outputs of each of the four channels are isolated to maximize channel separation. Transformer isolation on each output helps to eliminate system ground loops. It is a rock solid, roadworthy interface for connecting outputs of electronic musical instruments (or other audio sources) to the balanced inputs of mixer consoles and other balanced audio products. The PDB4 also allows connection of a music source to an instrument amplifier while simultaneously patching it to a mixer.Features: Four Fully Isolated Channels Switchable Input Attenuation (0dB, -20dB , -40dB) 50k Ohm Instrument/Line Input 50k Ohm Parallel Link Jack 600 Ohm XLR Output Jack Switchable Ground Lift 1U 19-inch Chassis Specifications: Frequency Response: 10 Hz - 50 kHz +/- 0.5dB @ +4dBu Input Connections: 1/4-inch TS unbalanced Output Connections: XLR male balanced Input Impedance: 50k Ohm Output Impedance: 600 Ohms Ground Lift: Switchable Input Attenuation: Switchable (0dB, -20dB, -40dB) Chassis Type: All steel black finish Power Requirements: None Totally Passive Dimensions: 1.75" x 19" x 6" (44.5mm x 483mm x 152mm) Weight: 6.5 lbs.
