MB SERIES

Installation:

To insure proper operation and to avoid potential 

safety  hazards,  place  the  unit  on  a  firm,  level 

surface.

Ventilation:

Make  certain  that  proper  space  is  provided  for 

ventilation.  Never  block  the  fan  vent  holes 

located  on  the  sides  of  the  amplifier.  If  the 

amplifier  will  be  installed  in  a  rack  or  other 

enclosed area, make sure that there is sufficient 

air  movement  within  the  enclosure  to  allow 

proper  cooling.  Consult  your  dealer  for  more 

information. Avoid installation in extremely hot 

or cold locations, and areas that are exposed to 

direct sunlight, or near heating equipment. Avoid

moist or humid locations.

Remember, power amplifiers generate heat. The 

ventilation slots on the enclosure are specifically 

designed  to  remove  this  heat.  Blocking  or 

placing other electronic equipment near the heat 

dissipation  system  may  possibly  affect  the 

long-term reliability of both your amplifier and 

the other equipment.

Moving the Unit: 

Before moving the unit, be certain to disconnect 

any  interconnection  cords  with  other 

components, and make sure that you disconnect 

the unit from the AC outlet. 

Cleaning:

When the unit gets dirty, clean only with a dry 

cloth.  Never  use  benzene,  thinner,  alcohol,  or 

other  volatile  cleaning  agents.  Do  not  use 

abrasive cleaners, as they may damage the finish 

of metal parts. Avoid spraying insecticides near 

the unit. 

Maintenance:

Your new amplifier is rugged. It was built to give 

you a lifetime of trouble-free operation, if it is 

operated  in  accordance  with  the  instructions 

contained in this manual. The only maintenance 

required  is  cleaning.  If  you  are  going  to  move 

your  amplifier  around  frequently,  we 

recommend  a  road  case  to  protect  it  from 

scratches and road wear. 

Packaging:

The carton and packing materials used in shipping

your new amplifier were specifically designed  to

cushion it from the shocks and vibration that occur

during transport. We suggest that you save the

carton and packing materials for use in shipping, in

the event you move, or the amplifier  needs repair.
