AD11
Operation
8
- The USB output can be used to connect to a Windows
®
PC or Apple
®
computer that supports USB
2.0.
There are no drivers to install; but ASIO4ALL can be installed on Windows PC’s for use with
ASIO compliant software. Please see the next section for details on USB operation.
Once the inputs and outputs have been connected:
- Connect the AC power cord to the AD11
’s back panel power entry receptacle.
- Connect the AD11 and other devices to an AC power source. The AD11 will automatically adjust to
AC power inputs in the range of 90-264 VAC- no need to change settings!
USB Operation
The AD11 has a USB output compatible with the USB 2.0 standard. It is not necessary to install any
drivers with Windows
®
OS or Apple
®
OS for basic operation.
For ASIO operation, ASIO4ALL is available as a free download and can be used to make the AD11
operate as an ASIO input device. Please note that the operation varies when using ASIO4ALL and
some of the Windows settings may be bypassed. For example: the recording software’s sample rate
settings over-ride the SOUND control panel settings, the level control does not function, and there is
no level indicated on the “meter” next to the “Microphone 2-Lavry ADC” in the Recording tab when the
ASIO application (recording software) is opened. Also, if the SOUND control panel is open at the
same time as the recording application, the input signal may be unavailable to the recording software.
W
ith the OS started normally and the AD11 power “On,” connect the USB cable from the AD11 to a
USB port on the computer. Although the AD11 should now be capable of inputting digital audio to an
application, it is a good idea to change a few settings for “bit-accurate” operation.
Windows ® XP
:
Open the SOUND control panel, and in the Sound and Audio Device Properties dialog, select the
Audio tab. In the SOUND RECORDING section, select the Lavry ADC as the Default Device from the
drop-down list.
Due to the nature of the USB interface, for highest quality it is advised that you set the AD11 to the
same sample frequency as the recording software.
Windows ® Vista/Seven-
Due to the nature of the USB interface, for highest quality it is advised that you set the AD11 and the
setting in the SOUND/Recording Device/”Microphone Properties”/Advanced tab Settings to the same
sample frequency as the recording software.
In the SOUND control panel Recor
ding tab, the AD11 will appear as a “Microphone.” Either click on
the “Lavry ADC microphone” and then on the Properties button in the lower right, or just double-click
on the “Lavry ADC microphone” to open the Microphone Properties dialog. Under the Microphone
Properties Advanced tab, choose the desired sample frequency for the “Default Format.” The level
control will need to be set to “3” (percent) or -0.4dB to avoid clipping.
The settings for Exclusive Mode
may also affect operation with audio software- check them if you have problems.
Apple
®
OSX-
Due to the nature of the USB interface, for highest quality it is advised that you set the AD11 and the
setting in the Audio MIDI Setup/Audio Devices/Lavry ADC- Input Settings to the same sample
frequency as the recording software. Please be certain that your audio software is open first, as this
can affect whether or not the setting dialog appears in the right pane of the Audio Devices dialog.
- S
elect “Utilities” from the Finder “GO” menu. For easier access in the future, you may want to drag
the “Audio MIDI Setup” to the Dock. Open the “Audio MIDI Setup” dialog. Choose AUDIO DEVICES.
If the Lavry AD11 is connected, it should appear in the left pane of the Audio Devices dialog as “Lavry
ADC, 2 In/0 Out.” Click on it to select it. If a small black microphone symbol is not preset on the right
side of the Lavry ADC section, at the bottom of the left pane, click on the down arrow next to the gear
