The VM2141AU is an 8-out Audio Output Card  
designed for use in a V-Matrix™ enclosure can  
handle a wide array of signal formats and  
connector types. When installed in a V-Matrix™  
Basic Enclosure, these Audio Output cards enable  
the connection of eight audio sources. For inputs,  
the VM2142AU can be used with the VM2141AU 8-  
in Audio Input Card. See the VM2141AU for more

Table 1. VM2142AU  
The 8-input video cards provide built-in ground loop  
isolation (GLI on Board™) through the use of  
differential inputs. This is an extremely important  
feature because it protects against hum bars and  
other interference caused by ground loops, which  
notoriously wreak havoc on large-scale matrix  
systems. Both the input and output video cards  
provide a bandwidth of 350 MHz @ –3dB, allowing  
them to pass extremely high-resolution computer  
video signals without signal degradation.  
All input and output cards are “hot-swappable” with  
finger adjustable lock-down screws and secure,  
positive engagement card-edge connections.

INSTALLING YOUR VM2142AU

We have carefully tested and have found no  
problems in the supplied VM2142AU; however, we  
would like to offer suggestions for the following:  
Step 1. Slide the VM2142AU and the VM2141AU  
into available slots in the V-Matrix™  
Enclosure. Make sure that the cards fit  
into place. Secure the cards to the V-  
Matrix™ by tightening the retainer screws  
located on the top and bottom of each  
cover plate.  
·
Make sure that power is connected to the  
enclosure and also check to see if the  
VM2142AU is pushed in all the way.  
·
If there is no sound, check the source and  
make sure that it is working at an appropriate  
volume level and all source connections are  
correct.  
Step 2. Connect audio cables from the audio  
source to the input connector of the  
VM2141AU.

equipment through an audio cable.  
OPERATION

Make sure that the destination amplifier is  
powered. Set the volume of the destination  
amplifier to a reasonable level.  
The VM2142AU will operate successfully as long  
as the card is installed properly and other technical  
specifications are followed.  
Make sure that the source signal level is high  
enough so that the destination amplifier does  
not have to provide excessive amplification and  
thereby distort the signal.
