The AX901 is a high quality 2 channel amplifier designed for a wide
 
−
variety of applications in the video studio.  With quality audio (ie.
 
−
VHS HiFi) becoming increasingly important in video productions, it has
 
−
become essential that the video producer use audio monitoring equipment
 
−
of a higher grade than is found in typical monitor/receivers.  However,
 
−
traditional "professional audio" gear
 
−
has been beyond the budgets of many video producers, and they have opted
 
−
for consumer HiFi gear normally sold in HiFi shops and department
 
−
stores.
 
−
 
−
Now, JVC would like to bridge this gap by offering the right products at
 
−
the right price--through its Professional Video Dealers.
