In other words, the same analog input level will result in digital “clipping;” but the average
output level of typical music program
will be 3dB’s
louder
.

hold.
This setting enables and disables the
LEVEL meters’ peak hold function. In
Operating mode when
hold
is enabled, a single LED representing the highest peak level
stays illuminated on each channel until the
exit/set
switch is clicked in the
set
direction.
Diagram 1, Section 2- LEVEL DISPLAY METERS (Operating mode)
This section displays the digital level of the output signal of the AD11 in decibels referenced
to
“Zero dB Full Scale” digital level (all bits “On”) which will be referred to as “0dBFS.” The
numbers above the display apply in Operating mode (
-42
,
-36
,
…,
0
) and represent the peak
signal level in dB’s below 0dBFS. Just to the left of the display, the legends
left
and
right
indicate which input channel the meters display.
Diagram 1, Section 3- GAIN CONTROLS (Setting
and
Operating Mode)
This section contains the GAIN display and
separate “
up/down
” switches for the
left
and
right
channels.
- The
up/down
switches always control the gain in both Operating and Setting modes.
- The display can show the gain setting for either channel. The gain for each channel is
displayed when the
up/down
switch
for that channel
is activated, and for approximately ten
seconds afterwards. The GAIN display then reverts to “LE” to indicate that the GAIN settings
have been stored in non-volatile memory.
- Because the same GAIN controls are used for both Line level and Microphone inputs,
there are two different GAIN ranges. The range from 0 to 12dB of gain is for line level inputs,
and the range from 20 to 65dB is for microphones or other balanced low-level, low
impedance sources. The GAIN display
will STOP changing and flash
before the GAIN is
changed from 12db to 20dB, or from 20dB to12dB to indicate the change in operating
modes. It is necessary to release the GAIN toggle switch, wait for the display to stop
flashing, and then press it again to transition from one range to the other. Please see the
Operating section of the manual for more details. For clarity, the condition “within the Line or
Mic range” may be omitted (below).
- If
“LE” appears in the GAIN display and the
up/down
switch is
“clicked” once, the GAIN
setting for that channel is displayed
without change to the setting
. If the display has not
reverted to “LE” and the same switch is clicked again, or held (either up or down), the gain
setting will change.
- If the numerical GAIN setting is displayed and the switch for the
other
channel is clicked
once, the setting for the other channel is displayed without change.
- If the numerical Gain setting is displayed, and the switch for that channel is clicked once,
the gain changes by one dB. There is an “acceleration” function, so when the switch is held,
the gain setting changes slowly at first, and then more rapidly the longer the switch is held.
- The GAIN display shows
“LE” at other times to indicate that the settings have been stored
in memory
. Again, to simply check the Gain setting for each channel, click that channel’s
up/down
switch once. The setting will be displayed without change from the stored value if
“LE” is displayed, or the other channel’s numerical gain setting was being displayed.
USB Connection-
Please see “USB Operation” in the Operation section of the manual (on
page 8) for more details on computer audio settings. The AD11 appears as a Core Audio
input device in Apple OSX and a WDM input device in Windows OS. ASIO4ALL can be
used with PC’s with ASIO compliant recording software.
