CHAPTER 2
Installation
Unpacking
The ES4000A is supplied with the following items. Contact the shipper or your Audiocom dealer immediately if anything is
damaged or missing. Detach and fill out the registration card and return it to Telex to properly register you intercom station.
Configuration Pre-check
Before making connections, read the configuration notes that follow, and make sure that all switches and jumpers are properly
set for your intended usage. Locations of configuration switches and jumpers are shown in Figure 2 on page 4. Only the DIP
switches and jumpers require internal access. If access is required, remove one screw from the top cover and 3 screws from
each side.
DIP Switches
DIP switches and their default settings are listed in Table 1 on page 6. The following paragraphs provide additional details.
Program Interrupt DIP Switches
Each Intercom channel has a dedicated program input. These can be used to feed background music, mix-minus audio (for
broadcasting usage) etc. to the intercom channels. If external program sources will be connected to the ES4000A, you have a
choice of whether or not you want the program audio to interrupt (shut off) on the intercom channel while the US2000A/
ES2000A station operator is talking.
