The RU‑DA4D is the ideal choice in most applications where line‑level signals need to be distributed. Each of two line‑level inputs permit the connection of either balanced or unbalanced, high or low impedance audio lines. Both may be connected to a single line source to provide up to eight distributed mono signals.
The inputs may be connected to left and right sources to drive four stereo outputs.Each of the outputs are provided with a front‑panel screwdriver gain control. Relative to the input level, this gain potentiometer allows an adjustment ranging from 15 dB loss to 18 dB gain. Each of the outputs drive balanced audio lines, and may be unbalanced if required.Audio presence is indicated by an LED for each of the two inputs.Inputs (2): Line Level (+4 dBu nominal)
