2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com to check for up-to-date
user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer 106 away from moisture, excessive sunlight and dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

Always switch off the power to each device before connecting it to your
106. After connecting your 106, connect its power and then switch on
the power to each device.
To connect the 106 as illustrated in the example in Figure 2:
1. Connect a mono balanced microphone to the MIC IN terminal block
connector.
2. Connect the LINE OUT 1 terminal block connector to a power amplifier
and/or the LINE OUT 2 terminal block connector to a power amplifier.
3. Connect each power amplifier to a loudspeaker.
4. Connect the 12V DC power adapter to the power socket, and connect the
adapter to the mains electricity.
5. Adjust the audio level via LEVEL Trimmers, if required.
Use the LINE OUT 1 trimmer to adjust the line 1 output, use the LINE OUT 2 trimmer to
adjust the line 2 output, and use the MASTER trimmer to adjust both line outputs.
