4.  MIC/LINE1  BALANCED  XLR  INPUT

-This  female  XLR  connector  provides  the  input  for 

channel 1. 

 

5.  LINE3  GAIN  CONTROL

-  This  control  determines  the  gain  of  the  MIC/LINE  channel  1.  

When  using  this  input  for  a  line  level  input,  the  gain  should  be  set  a  minimum.    The 
Microphone preamp provides up to 50db of gain. 

 

6.  LINE3 BALANCED XLR INPUT

-This female XLR connector provides the input for channel 

3. 

 

7.  MIC/LINE2  GAIN

-  This  control  determines  the  gain  of  the  MIC/LINE  channel  1.    When 

using this input for a line level input, the gain should be set a minimum.  The Microphone 
preamp provides up to 50db of gain. 

 

8.  MIC/LINE2  BALANCED  XLR  INPUT

-This  female  XLR  connector  provides  the  input  for 

channel 2. 

 

9.  POWER 

LED 

–When lit this LED indicates that the VMAX power is on. 

 

10. LIMIT 

LED 

– This LED lights when the internal limiter is active.  This LED will flash when 

the  signal  level  at  the  input  of  the  power  amplifier  is  at  maximum  i.e.  where  the  power 
amplifiers  will  start  to  clip.    When  the  input  to  the  amplifier  reaches  the  point  where  the 
limiter becomes active, any increase in input level will be limited at the input to the power 
amplifiers.    This  will  allow  the  VMAX  to  play  at  maximum  level  but  not  allow  the  speaker 
produce large amounts of distortion.    

 

11. SIGN

AL LED 

– This LED lights when the input signal exceeds –25dbu. 

 

12. LINK OUTPUT 

CONNECTOR-  This  output  provides  a  line  level  output  signal  that  can  link 

two VMAX cabinets together.  Two VMAX speaker cabinets can be linked together allowing 
both VMAX speakers microphone preamps to sum together and feed both VMAX speakers 
power amplifiers in mono.  By connecting a cable with two female XLR connectors from the 
link  output  of  one  cabinet  to  the  link  output  of  the  second  cabinet  all  four  microphone 
preamps will sum together and feed both VMAX speaker cabinets.

   In the configuration above, you can still use Line3 inputs as stereo inputs if desired.
