Universal Audio Delay Processor 3.2 Windows-Based Software GUI The AD-340 Programmer is a software-based solution capable of configuring any setting on one or more AD-340 devices connected to the Windows PC via a valid USB connection. 3.2.1 Installation A compatible PC with Windows XP™ or later operating system with a USB connection is required: •... -
Page 10: Operation
The AD-340 Audio Delay automatically configures as a HID (Human Interface Device) and does not require any USB drivers installed by the end-user. When the AD-340 is attached to a valid USB port, the Windows™ system will automatically detect and identify the appropriate USB driver. There may be a short delay while this process occurs. - Page 11 Power Selection Device is powered on and enabled Standby: Device is powered off and disabled Device Name Used to give the AD-340 device a descriptive name up to eight (8) characters long. The DEFAULT name is USBDEVHR.

The Encoded Bitstreams Formats must be decoded by an A/V receiver or similar audio equipment with embedded Dolby Digital or DTS decoder for full 5.1 channel functions. (Note: Analog Audio is auto-muted when the AD-340 detects a non-PCM bitstream). Press the SELECT button for Audio Input Type Selection. LEDs... -

Dolby Digital Stereo and Surround (only digital output) DTS Surround (only digital output) DTS-CD Surround (only digital output) The AD-340 indicates SPDIF Errors and if SPDIF is Unlocked on the SPDIF PLL lock Range: 32 kHz to 196 kHz 3.3.2 Sampling Rates For Analog Input, the user can choose between 48 kHz (for quality audio) or 32 kHz (for increased delay time) sampling rates. -
Page 16: Analog Input/Output Volume Control
Model AD-340 3.3.4 Analog Input/Output Volume Control The analog input and output is set to Line Levels for CD, DVD and BD Players at (5.6 V- ), so if any of these sources are used the volume control Vrms peak-to-peak should be set to Unity Audio Gain (Default). - Page 17 The speed of sound increases with a rise in temperature and decreases with a fall in temperature. The AD-340 Audio Delay Processor is designed to provide a flexible way to adjust for these types of delay by adding a digital delay function based on 5 different delay types.
- Page 18 Model AD-340 In calculation of delay needed for given distance the unit includes correction needed for Haas effect. This correction masks localization of delayed audio source, so the listener still perceives the sound coming from far source. The maximum number of milliseconds of delay possible is a function of the audio...

Why do the 4 Front Panel LEDs only blink when I power on the unit? The AD-340 verifies that the internal firmware is valid. If an error is detected, the system will automatically wait for firmware to be loaded. This should never happen in normal use, but the GUI can be used to reload firmware into the system. -
