3.6 Levels, Levels, Levels
Ok, we assume that you just made a call to yourself in section 3.5, above (if not, please
follow those steps now). Congratulations, you just have some tweaking to do and your
basic installation & configuration will be complete!
• Bring up some audio on the console (mixing desk). Spoken word is best, as it tends
to have a lot of dynamics, but music will work. While tone will work for the coarse
adjustments (set it to the red-green boundary point), we do not recommend using it
for final adjustments. Adjust the levels on the board to the levels set by your typical
operator! NOTE: If your board operators typically run “into the red”, you should
do the same! For now make sure the faders for both of the hybrids are TURNED
OFF.

IMPORTANT!

• Set the left LED meter to STUDIO IN, if necessary, by pressing the button located
on this meter. You should see the audio from your console on these meters (the
send-to-hybrid 1 audio will be on the LED bargraph labeled 1 and the send-to-
hybrid 2 will be on the LED bargraph labeled 2.
• Observe the levels on these two meters. You will note that the highest peak level
reading is represented by a “floating” LED that persists near the top of the meter.
Since our goal is to set the levels so that peak levels do not hit 0dBfs, this peak
reading is what we need to watch. Section 7.1 has more information on the
TWOx12’s metering.
• First set the Input Gain selection found in the Audio Settings menu to a nominal
level close to that used in your facility (i.e. –7, 0, +4, or +8 dBu). This control sets
the level for both inputs. If the inputs are not reading identically, you will need to
adjust them at the output of the console. Note that the lower this selection is set,
the higher the levels on the unit’s meters, as this setting represents nominal input
level.
• Next adjust your console output (mixing desk) level (for the mix-minus) if
necessary. We suggest that you keep the peak level below a -4 to -6 reading, this
will allow some room for error on the part of your operators. If you are using a tone
to set levels you may need to set them considerably lower.
