4.4.5 Line In Trim
Line In Trim can be set to any of eight preset trim settings. The Line In Trim button shows the currently selected trim
level, the same for the Left and Right inputs.
There are four Pro Level settings: +18 dBu; +20 dBu; +22 dBu; and +24 dBu. There are four additional levels most
often used on Consumer Audio products: +0 dBV; +2 dBV; +4 dBV and +6 dBV.
When the button is pushed, a Selection Window pops up. Pushing the desired Level button resets the inputs and
immediately indicates this on the Line In Button. You will typically hear a relay click from inside Hilo when a
selection is made.
Note: These are 0dBFS (full-scale) level settings, as opposed to nominal levels.
Trim pots are available to fine tune these inputs. See Appendix 5.2 for more information.
4.4.6 Line Out Trim
Line Out Trim can be set to any of eight preset trim settings, the same as for Line In.
This works exactly the same as the Line In Trim. Push the button and make your selection.
Note: Each Line In and Line Out Trim can be adjusted ±0.5 dB of the established trim settings using the trim pots that
are located on the bottom of the circuit board. See Appendix 5.2 for more information.
