* 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.
