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

3 Overview
The VS-81SP is a bi-directional switcher for stereo audio speaker signals on
terminal block connectors. It can switch any one of eight pairs of input
signals to one output pair or one input pair to any one of eight output pairs.
The VS-81SP has the following features:
• 8 x 1 input/output stereo connections wit h bi-directional
functionality
• The ability to cascade up to seven units to increase the number of
inputs or outputs
• The ability to handle both high-impedance (100/70V) and
low-impedance (8/4Ω) signals
• Control from the front panel, or via RS-232/RS-485 serial
commands transmitted by a touch screen system, PC, or other
serial control device, as well as via an infrared remote controller,
or via remote contact-closure switches
To achieve the best performance:
• Use only good quality connection cables
1
• Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
VS-81SP away from moisture, excessive sunlight and dust
to avoid interference,
deterioration in signal q uality due to poor matching, and elevated
noise levels (often associa te d with low quality cables).
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provide d with this unit
2
.
Warning – Di sconnect po wer and unplug unit from wall
before i ns talling or removing device or ser vicing unit.

Installing the VS-81SP in a Rack
5 Installing the VS-81SP in a Rack
This section descr ibes how to install the VS-81SP 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 +5º to +45º C (41º to 113º F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20º to +70º C (-4º to 158º F)
Storage humidity range 5 to 95% RHL, non-condensing
When installing on a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the op era ti ng ambi ent t e m pera tur e 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 positi on.
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 t he app ro priate
nameplate ratings for information. For example, for
fuse replacemen t, s ee the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected onl y to an ele ctric ity 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.

Connecting the VS-81SP 8 x 1 Loudspeaker Switcher
6 Connecting the VS-81SP 8 x 1 Loudspeaker Switcher
To connect the VS-81SP, as shown in Figure 2, do the following
1
1. Connect the input source (for example, the speaker outputs from a power
amplifier) to the OUT/IN terminal block connectors.
:
2. Connect the IN/OUT connectors to the speaker pairs (up to eight).
3. As an option you can connect a PC and/or controller to the:
• RS-232 port (see section
6.1)
• RS-485 port (see section
6.2)
4. Set the DIP-switches (see section
6.3).
5. If required, connect remote contact-closure switches to the REMOTE
terminal block connect or (see secti on
6.4).
6. Connect the power cord to the power s ocket an d c onn ect the pow er c ord to
the mains electric ity.
Note: In a reverse configuration (see
Figure 3), you can connect up to eight
power amplifiers to the IN/OUT input connectors and one speaker pair to
the OUT/IN output connector.
1 Switch OFF the power on each de vice before connecting it to your VS-81SP. After connecting your VS-81SP, switch on its
power and then switch on the power on each device
