Overview
The high performance 104B 1:4 Microphone DA accepts an input from a
microphone and distributes that signal simultaneously to four outputs. In
particular, the 104B features:
Audio level control
A switch for applying phantom power1
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noiselevels (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.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit2.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
1 This is for applications that require typical condenser microphones to be connected directly to the 104B To prevent
unnecessary damage, apply phantom power to the Mic only when required
2 For example: model number AD2512C, part number 2535-000251
