- Page 5 AC power. But first, here are some basics: -When AC power is applied to the AD11, the unit initializes itself. First, a single LED “scans” each row of the front panel meters, then both rows. The unit then enters a special version of Setting Mode to display the settings and allow changes to the phantom settings for the left and right channel’s +48V Phantom power.
- Page 6 12.) Now that you are familiar with the Setting mode, you can re-enter setting mode and configure the AD11 for the settings you normally use. It is advisable to disable phantom power unless you plan to use a condenser microphone with the AD11 the next time power is applied. The default settings can be used safely for initial operation.
- Page 7 “lock” to the external signal. The two types of sync are “wc” for Word Clock or “dig-a” for AES or SPDIF sync. If the AD11 is not “locked,” or there is no signal present on the sync input, the LED in the upper row above wc or dig-a remains dark.
- Page 8 - Exiting Setting Mode causes the settings to be stored in non-volatile memory. This means the AD11 will retain the settings even if the AC power is turned “off.” Any time the GAIN display reverts to the “LE” symbol, the Gain settings are also stored.
- Page 9 10 for more details- the wc Lock indicator is labeled “a” in Diagram 2. - If the external wc function is “On” as indicated by the LED, the AD11 will lock to TTL level sample-period Word Clock signals applied to the “clock in” BNC connector on the rear panel.
- Page 10 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...
- Page 11 The input has 75 Ohm termination. - Connect the BNC clock out to another device’s Word Clock input to synchronize it to the AD11 operating on Internal Clock. The receiving device must have 75 Ohm termination.
- Page 12 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.
- Page 13 OPERATION: When AC power is applied, the AD11 initializes itself. First, a single LED “scans” each row of the front panel meters, then both rows. The unit then enters a special version of Setting Mode to display the settings and allow changes to the phantom settings for the left and right channel’s +48V Phantom power.
- Page 14 Line or Mic range. Gain changes within a range can be made at any time. Although the AD11 changes its digital outputs “gracefully;” it is not possible to predict how a device the AD11 is feeding will react. For these reasons; it is advisable to lower your monitor speaker volume to avoid possible speaker damage prior to changing the relevant settings.
- Page 15 The Sample Frequencies (SF) setting controls the digital audio and Word Clock outputs of the AD11. When operating on external clock, it is also necessary to set the SF of the AD11 to match the SF of the external clock source.
- Page 16 - Immediately after AC power is applied to the AD11, the unit goes through an initialization sequence. First a single LED “scans” each channel of the meter, then both channels. Next, the AD11 enters a special version of the Setting mode to allow the user to check and change the settings of the Phantom Power, if desired.
- Page 17 The LEVEL meters will display the peak digital level of the output of the AD11. Any changes to the level of the analog input source or the gain of the AD11 will be reflected in the AD11’s digital output level, and thus the AD11’s LEVEL meters. The meters are very accurate, and take into account every...
- Page 18 AD11 for line level inputs and the other channel for a condenser microphone input at the same time. As long as the AD11 is operated in the Line level range, there is no possibility of the phantom power being applied to a Line output feeding the AD11. The Microphone preamplifier is optimized for...

Page 19: Specifications
SPIDF digital audio interface (PCI soundcard, FireWire, or USB). This is due to the nature of computer audio, and is not unique to the AD11, which has a conversion delay similar to most other contemporary AD converters. The AD11’s conversion delay is related to the Sample Frequency (SF), and is shorter for higher SF’s. - Page 20 If you have any questions, contact: techsupport@lavryengineering.com Please Note: The AD11 automatically adjusts to AC power inputs in the range of 90 to 264 Volts AC and line frequencies between 47 and 63 Hertz. There are no settings to change.
