3 Overview
The 102xl 2 Channel Audio Mixer is a high quality, low noise, 2-input mono
balanced audio standalone mixer that provides for 2 different levels on each
input - Mic level or line level as well as the selection of either a dynamic or
phantom microphone.
The 102xl includes:
Two XLR input connectors and one XLR output connector
A MASTER knob for adjusting the level of both input signals mixed into
the output, and two LEVEL knobs, for adjusting the levels of each input1
separately
A 12 VDC power socket, which is ideal for field use. The unit generates
broadcast voltage level ±12V and +48V internally from the single
+12 VDC input
Two input level select switches1 for selecting the balanced level (MIC or
LINE)
Two switches1 for applying 48V phantom power2
Achieving the best performance means:
Connecting 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)
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your 102xl in a location
free from moisture and away from 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 unit3.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.
1 Each corresponds to its respective input
2 This is for applications that require typical condenser microphones to be connected directly to the 102xl. To prevent
unnecessary damage, apply phantom power to the Mic only when required
3 For example: model number AD2512C, part number 2535-000251

To connect up to two balanced audio sources to the 102xl 2 Channel Audio
Mixer unit, as the example in Figure 2 illustrates, do the following1:
1. Connect a balanced audio source (for example, a condenser microphone)
to the INPUT 1 XLR female connector.
Set the INPUT LEVEL SELECT IN 1 switch to MIC.
Set the PHANTOM 48V IN 1 switch to ON2.
2. Connect a balanced audio source to the INPUT 2 XLR female connector.
Set the INPUT LEVEL SELECT IN 2 switch to LINE.
Set the PHANTOM 48V IN 2 switch to OFF.
3. Connect the XLR male OUTPUT connector to a balanced audio acceptor
(for example, a power amplifier with speakers).
4. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
5. Rotate the INPUT 1, INPUT 2 and MASTER LEVEL knobs to adjust the
audio level of input 1, input 2 and of both inputs mixed together3 to the
output, respectively.
For every unused input, be sure to rotate the LEVEL potentiometer fully
counter-clockwise (to the minimum level).
1 Switch OFF the power on each device before connecting it to your 102xl. After connecting your 102xl, switch on its power
and then switch on the power on each device.
2 When using a dynamic microphone, set the PHANTOM 48V switch to OFF
