Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better!

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 www.kramerav.com/downloads/PA-240Net or www.kramerav.com/product/PA-120Net to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).

Achieving 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 PA-240Net/PA-120Net 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.

Safety Instructions

Caution: There are no operator serviceable parts inside the unit. Warning: Use only the power cord that is supplied with the unit. Warning: Do not open the unit. High voltages can cause electrical shock! Servicing by

qualified personnel only.

Warning: Disconnect the power and unplug the unit from the wall before installing.

PA-120Net, PA-240Net – Connecting the PA-240Net

Connecting the PA-240Net

Always switch off the power to each device before connecting it to your PA-240Net. After connecting your PA-240Net, connect its power and then switch on the power to each device.

To connect the PA-240Net as illustrated in the example in Figure 1:

1. Connect the balanced stereo audio source to the AUDIO IN 5-pin terminal block connector (for example, a Kramer Switcher/Scaler).

2. Connect the LINE OUT balanced stereo audio 5-pin terminal block connecter to a balanced stereo acceptor (for example, an additional PA-240Net device).

3. Connect the Hi-Z OUT or Lo-Z OUT 4-pin terminal block connector as follows:

▪ For Hi-Z connection: connect Hi-Z and COM terminal blocks to the + and – terminals

of a mono speaker (for example, the Galil 8-C ceiling speakers, daisy chained). The speakers either output the left side (L+, L-) of the audio input or the stereo input reduced to a mono signal (see Selecting Hi-Z Mono Settings on page 16).

▪ For Lo-Z connection: connect the L+ and L- connectors to the left-side speaker and

the R+ and R- connectors to the right-side.

4. Set the Hi-Z/Lo-Z and 100V/70V DIP-Switches :

▪ For Hi-Z operation: Set DIP-switch 1 to Hi-Z and then set DIP-switch 2 to 70V or

100V.

▪ For Lo-Z operation: Set DIP-switch 1 to Lo-Z.

5. Connect the Dante RJ-45 connector to any available IP network.

6. If required, connect:

▪ A PC via RS-232 , see Connecting to PA-240Net via RS-232 on page 8. ▪ The ETHERNET port , see Connecting PA-240Net via the Ethernet Port on

page 9.

7. Connect the power cord (not shown in Figure 1).
