 Audio level control 
 A switch for applying phantom power

To achieve the best performance: 
 Connect only good quality connection cables, thus avoiding interference, 
deterioration in signal quality due to poor matching, and elevated noise- 
levels (often associated with low quality cables) 
 Avoid interference from neighboring electrical appliances and position 
your Kramer 104B away from moisture, excessive sunlight and dust 
Caution – No operator-serviceable parts inside unit.

wall adapter that is provided with this unit

Warning – Disconnect power and unplug unit from wall 
before installing or removing device or servicing unit.

unnecessary damage, apply phantom power to the Mic only when required
