2.1 Quick Start
This quick start chart summarizes the basic setup and operation steps.

Overview

3 Overview
The VS-106 is a switcher/amplifier for unbalanced analog audio stereo
signals. The unit mechanically switches the single line input to one output,
either one of ten unpowered unbalanced audio stereo line outputs, or one of
six amplified speaker outputs. The unit does not switch to line and speaker
outputs simultaneously.
More specifically, the VS-106 features:
•Unpowered 1x10 mechanical line to line switching
•Amplified 1x6 line to speaker switching
•A loudspeaker volume knob
•A power ON indication LED
•A 12V DC power supply
•Standard 19” 1 U rack mount size
To achieve the best performance:
•Use only good quality connection cables1to avoid 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 that
may adversely influence signal quality and position your Kramer
VS-106 away from moisture, excessive sunlight and dust

5 Installing the VS-106 in a Rack
This section describes how to install the VS-106 in a rack.
Before Installing in a rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range:
To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
•In some models, the front panel
may feature built-in rack ears
•Detachable rack ears can be
removed for desktop use
•Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
•If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)
Operating temperature range +5°to +45°C (41°to 113°F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20°to +70°C (-4°to 158°F)
Storage humidity range 5 to 95% RHL, non-condensing
CAUTION!!
When installing on a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.

6 Connecting and Operating the VS-106
To connect the VS-106, as shown in Figure 2, do the following1:
1. Connect an unbalanced stereo audio source (for example, a stereo audio
player) to the LINE INPUT L and R RCA connectors.
2. Connect the LINE OUTPUT RCA connectors to up to 10 unbalanced stereo
audio acceptors (for example, stereo audio recorders).
3. Connect the OUT (SPKR) connectors to up to 6 speaker pairs (use only
passive, unpowered speakers).
4. Connect the 12V DC power supply.
To operate the VS-106:
1. Press the appropriate button on the LINE OUT SELECTOR (from 1 to 10)
or the LOUDSPEAKER OUT SELECTOR (from 11 to 16).
The line input switches to the selected line output or speaker.
2. Adjust the speaker volume by turning the LOUDSPEAKER VOLUME
knob.
Note: The power supply is only needed when operating loudspeakers.
No power is needed for line switching.
1 Switch OFF the power on each device before connecting it to your VS-106. After connecting your VS-106, connect its
power and then switch on the power on each device

6.1 Optional Gain Adjustment
You can set the overall gain of the loudspeakers by adjusting the gain
DIP-switches located on the circuit board inside the VS-106. Settings
available are 19dB, 25dB (factory setting), 31dB and 37dB.
To set the gain DIP-switches:
1. Remove the screws from the top and sides that hold the top cover.
2. Remove the top cover to access the circuit board.
3. Using a small screwdriver or pointed object, slide the DIP-switches to set
the desired gain (see Figure 3).
4. Replace the top cover and secure with the screws removed as per Step 1
above.
