R This control determines how much signal is present at the selected output. As with
channel faders, optimum setting is at unity gain (0). If the output level is too quiet or too loud at
unity gain, the gain and fader settings on the channels assigned to the Sub mix should be checked.
If two Sub mixes, Sub 1 and Sub 2 for example, are intended to be in stereo, adjust both Faders
equally and simultaneously to preserve balance.

T This switch activates the low-cut (150 Hz -18 dB/per octave) filter. With this feature
engaged, input frequencies below 150 Hz will be rejected. Especially when using reverb, the low-cut
filter is useful in reducing “low-end rumble” and making resultant sounds less “muddy.”

R These switches apply power (+48 V DC) to the Mic (XLR) inputs on channels
1–16 and 17–24 respectively (1–24 and 25–32 on the AAM 3243). This feature provides power to
microphones that need an external power source. These switches are recessed into the console and
require a small “tool” to activate. If Phantom Power is used, do not connect unbalanced dynamic
microphones or other devices that cannot handle this voltage to the XLR inputs. (Some wireless
receivers may be damaged. Consult their manuals.) A regular low-impedance mic will not be
harmed. The Line inputs are not connected to the +48 V supply and are safe for balanced or
unbalanced inputs. An adjacent LED will illuminate when Phantom Power is activated on its
respective channels.
