Overview

3 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 power
1
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.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
2
.
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
