The RDB104 is a four-channel active impedance matching device with the added benefit of a variable level control for each channel. Each channel of the unit has two 1/4" TS phone input jacks wired in parallel (one front and one back,) a male XLR output jack, a ground lift switch and a single position attenuator switch. Its design is ideal for a variety of applications including musicians, studios, and sound contractors.
