1. Introduction
The WAVE is a DSP based Audio delay that was specifically designed for the demands in
modern home theater setups. The sophistacted videoprocessing in todays digital displays and
processors can generate a significant delay between the video and audio information resulting
in severe lip sync issues. The WAVE can compensate this delay and resynchronize audio and
video information.
2. Adjustments
2.1 Delay
The WAVE offers 9 steps of delay adjustments.
The increments are in steps of 20ms up to 180 ms.
Removing an internal jumper changes increments from 20 ms to 40ms resulting in
a 340 ms maximum delay setting in steps of 8.
If the unit is controlled via RS-232 the 17 delay settings of the unit
may accessed directly in steps of 20 ms.
2.2 Inputs and automatic input selection
Inputs 1-7 may be selected manually using the front panel push button.
For automatic input selection please select 9. For proper operation of the automatic
input selection it is required that there is only one active source at a time and all other
connected audio sources are turned of.
The unit scans the inputs for active sources, so any time a new active source is present the
WAVE will switch to the according input.
3. Display
The WAVE has 2 LEDs status indicators. The red LED indicates that a valid digital audio signal
has been recognized. If this LED does not lit, you either have choosed an open input, or the
input signal is not recognized.
The green LED indicates that the unit is powered. If that is not lit, please check the power
connection and mains adapter.
4. Connections
On the frontplate you will find power connection and the RS-232 port for third party control.
4.1 Inputs
On the backplane of the unit there are 3 Inputs coaxial, 3 Inputs optical und 1 analog Stereo
input for all current audio standards. The WAVE processes analog Audio, PCM, Dolby Digital
and DTS data streams.
4.2 Outputs
The WAVE offers 2 audio outputs one optical and one coaxial that may be used
simlutanously. These outputs are typically connected to an input of an AV
receiver or Surround processor of your AV system.
5. Technology
Inside the WAVE we are using a digital signal processor for momentary memorization of the
audio stream. On the front end you will find a precise clock regenerator and resynchronisation
device. This design may improve the overall sound performance of your system as the
asynchronous operation of the WAVE removes jitter of the source. This usually results in better
3 dimensional sound and better sonic purity.
7. Serial control
Please get a serial null modem cable to control the WAVE remotely.
This kind of cable may be purchased in any computer hardware store.
RS-232 protocol:
Baudrate: 19200/8N1
Selection of inputs:
AU00>Enter< = Mute
AU01>Enter< = Coax 1
AU02>Enter< = Coax 2
AU03>Enter< = Coax 3
AU04>Enter< = Optisch 1
AU05>Enter< = Optisch 2
AU06>Enter< = Optisch 3
AU07>Enter< = Analog
AU08>Enter< = Automatic input selection
? >Enter< = Returns active input
Delay adjustment:
:
DL00>Enter< = no Delay
DL01>Enter< = 20 ms
DL02>Enter< = 40 ms
up to
DL17>Enter< = 340 ms
DL0? >Enter< = returns current delay setting
8. Integrated control WAVE /VIGATEC DUNE
Any DUNE higher serial number 2000 can control the WAVE device remotely.
First connect a serial null modem cable between WAVE and DUNE. In the DUNE
AUDIO menu you may assign a WAVE input and the delay setting for each of the 8 video
inputs.
After having saved the setting in the DUNE, the delay setting and input selection will be
executed any time you recall the input.
