2. Treble: This tone control adjusts the high frequency speaker audio response
from -12 dB to +12 dB. Lowering Treble compensates for high frequency
pre-emphasis or removes sibilance effects. Increasing Treble will add
"sizzle" to the sound and bring high-pitched sounds out of the mix. The
control can be touched and moved left or right to adjust in 2 dB increments.
After touching the Treble control, the Channel knob can also be turned to
make the adjustment.
3. Bass: This tone control adjusts the low frequency speaker audio response
from -12 dB to +12 dB. Lowering Bass will unmask midrange band sounds,
while increasing Bass will make the sound "fatter". The control can be
touched and moved left or right to adjust in 2 dB increments. After touching
the Bass control, the Channel knob can also be turned to make the
adjustment.
4. Set to Flat: Touching this button will set the Treble and Bass controls to
their midpoint, resulting in a flat response with 0 dB increase or decrease in
treble and bass response.

Unit Configuration
Touching the Unit Config selection on the Unit Settings Menu proceeds to the
Unit Config Menu. This menu is shown in Figure 2-23.
The controls function as follows:
1. Brightness: This setting adjusts the brightness of the display screen. Touch
the left pointing arrow to dim the brightness or touch the right pointing arrow
to increase the brightness.
2. AES termination: AES signals should have one and only one termination.
This termination should physically be at the last destination of an AES coax
cable. If the iAM-SUM is the last connection in a series of AES connections,
then its terminations should be turned on. A symptom of too many
terminations (or no termination) is that no signal appears to be present on
iAM-SUM
