    9. Utility Bridge Voltage Controlled Mixer Bus Voltage Controlled Mixer Bus A and Voltage Controlled Mixer Bus B are functionally identical and will both be covered by the following information. For clarity, references will be made to Bus A but the information applies equally to the corresponding Bus B.
  • Page 24 9. Utility Bridge Voltage Controlled Mixer Bus (continued) VCA Features The output of the three channel mixer is sent internally to the embedded VCA. The output level of the VCA is controlled in one of two ways. With nothing patched into CV Input If nothing is patched into the CV input (18) the VCA level is controlled manually using the CV|Output Knob (16).

    10. Utility Bridge Bus Outputs The Bus Outputs section offers 6 individually buffered outputs assignable to either Bus A or Bus B. To use Bus A, the Output Button should be unpressed and the Button LED should be off. To enable Bus B, the Output Button should be depressed and the Button LED should be lit.

  • Page 28: Utility Bridge Signal Attenuators

    11. Utility Bridge Signal Attenuators The Signal Attenuators section offers a few different functions. The section can function as two independent signal attenuators by patching signals to Input 1 (44) and Input 2 (47). The section can also be used as a buffered signal splitter with individual attenuation controls.
