106 - Getting Started

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.

106 - Overview

3 Overview

The 106 Mic Amplifier / DA is a high−quality distribution amplifier for balanced

mono microphone signals. It takes one dynamic or condenser microphone input

and distributes the signal to two high-level balanced mono line outputs, reaching

27Vpp (22dB).

The 106 features:

Three trimmers to adjust the LINE OUT audio level

A switch for selecting the type of microphone (condenser or dynamic)

Two balanced mono line outputs for power amplifiers

4 Connecting the 106

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.
