1 Introduction
1.1 General
Thank you for purchasing the professional and compact AD-340 Audio Delay
Processor from Hall Research. This User’s Manual applies to both the AD-340
Audio Delay Hardware and the Windows-based Audio Delay Software Graphical
User Interface (GUI).
The AD-340 can be configured directly from the Front Panel Push Buttons or
from the GUI when the AD-340 is connected to a Windows HOST PC with a USB
cable. The Software GUI for the AD-340 is designed to be an intuitive and
powerful user interface, and the front panel is simple and easy to use.
The AD-340 Audio Delay Processor provides both Analog (Left and Right Stereo
Channels) and Digital Audio Inputs and Outputs, including CD, DVD or Blu-Ray
Disc quality audio processing.
The user controllable Delay Functions allow an adjustable digital delay for
audio/video synchronization/timing alignment and for acoustic external delay
alignments for speaker systems located at different distances relative to the
listeners.
The AD-340 is equipped to adjust for virtually any environment. Even the Verizon
Amphitheater one of the largest venues in Southern California, is well within the
capabilities of this unit, which can adjust for distances of up to 510 feet (155
meters)
