1. Power Switch       

 

This switch controls the AC mains power to your

 

powered mixer. Power is on when the switch is in

 

the on(up) position and is confirmed when the power

 

LED indicator is illuminated.

 

Note : Before turing on or off the mixer. It is a good idec to

 

turn down the main master and monitor master controls.

 

2. FUSE     

 

The fuse is located in the fuse holder. (See Section

 

  Specifications for the correct values.)

 

3. IEC Socket     

 

This  is  where  you  connect  the  supplied  AC  line  cord  to 
provide

 

AC power to the all VM series powered mixer. Plug the line

 

cord into an AC socket properly configured for your particular

 

model. 
 

 

4. Monitor Out     

 

These two parallel speaker output jacks accept

 

standard 1/4

two-conductor phone plugs, providing

 

300 watts of power at 4 ohms, or 200 watts at 8

 

ohms. Load impedances less than 2 Ohms will not

 

draw additional power and may cause the unit to go

 

into protect mode. The SPEAKERS MONITOR A and B jacks

 

are  internally  connected  in  parallel,  and  output  the  same 
signals.

 

You can connect speakers with an impedance of 4-8ohm to

 

either or both the A or B jacks. You can connect speakers with

 

an impedance of 8-16ohm to both pairs.

 

 
 

 

NOTE :

 Do not connect any devices other than speakers to

 

these jacks. Do not confuse these jacks with the MONITOR

 

jacks on the I/O panel.

 

5. Right Out   

 

These two parallel speaker output jacks accept standard 1/4

 

two-conductor phone plugs, providing 300 watts of power at

 

4 ohms, or 200watts at 8ohms. 

 

Load impedances less than 4 ohms will not draw additional

 

power and may cause the unit to go into protect mode. 

 

6. L+R Bridge

 

These two parallel speaker output jacks accept standard 1/4

 

two-conductor phone plugs, providing 600 watts of power at 

 

4 ohms, or 400watts at 8ohms. 

 

Load impedances less than 4 ohms will not draw additional

 

power and may cause the unit to go into protect mode. 

 

7. Left Out

 

These two parallel speaker output jacks accept standard 

 

1/4

two-conductor  phone  plugs,  providing  300  watts  of 

power at

 

4 ohms, or 200watts at 8 ohms. Load impedances less than 

 

4 ohms will not draw additional power and may cause the unit

 

to go into protect mode. 

 

8. VM8-DRV Power Amp output

 

These two parallel speaker output jacks accept standard   
1/4

two-conductor phone plugs, providing 300 watts of power 

at 4 ohms, or 200watts at 8 ohms. Load impedances less than 
4 ohms will not draw additional power and may cause the unit 
to go into protect mode

.

 

 

  When the Stereo/Bridge select switch is set 

 

      to STEREO (2-Channel connection)

 

L/R channel signals are routed from the ST(L,R) bus to the

 

SPEAKER  L/R  jacks.  The  SPEAKERS  L  A/B  jacks  are 
internally

 

wired in parallel and output the same signals. You can connect

 

a pair of speakers with an impedance of 4-8ohm to either or

 

both the A or B pair of the SPEAKER L/R jacks(total of two

 

speakers). You can connect two pairs of speakers with an

 

impedance of 8-16ohm to both A and B pair or the SPEAKER

 

L/R jacks(total of four speakers).

 

This  connection  provides  a  maximum  output  of  300W  + 
300W.

 

 

NOTE:

 Do not connect anything to the SPEAKERS L+R 

 

BRIDGE jack when you are using this 2-channel connection.

 

 

  When the Stereo/Bridge select switch is set 

 

      to L+R BRIDGE (BRIDGE connection)

 

L/R channel signals are mixed in the ST bus and routed to the 
SPEAKERS L+R BRIDGE jack as a monaural signal. You can 
connect only one speaker with an impedance of 8-16ohm to the 
SPEAKERS L+R BRIDGE jack. This connection provides the 
maximum output of 600W

.

 

 

NOTE

:

  Do  not  connect  anything  to  the  SPEAKERS  L/R  jacks 

if you use this BRIDGE connection.
