Getting Started

2.1 Quick Start

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

Overview

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 with 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 cables1

•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 quality due to poor matching, and elevated

noise levels (often associated with low quality cables).

Caution – No operator-serviceable parts inside unit.

Warning – Use only the Kramer Electronics input power

wall adapter that is provided with this unit2

Warning – Disconnect power and unplug unit from wall

before installing or removing device or servicing unit.

Installing the VS-81SP in a Rack

5 Installing the VS-81SP in a Rack

This section describes 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

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.

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 following1

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 connector (see section 6.4).

6. Connect the power cord to the power socket and connect the power cord to

the mains electricity.

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 device 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
