4. Referring to Table 1, connect the antennas to the antenna inputs on the SR 4000 receiver.
If you need one or two AB 4000 antenna boosters, you will need to insert an ASU 4000 remote power
adapter between the receiver and the first antenna booster.
5. Check that the AC mains voltage stated on the power supplies for the ASU 4000 and the receiv-
er is identical to the AC mains voltage available where you will use your system. Using the
power supplies with a different AC voltage may cause damage to the unit.
6. Connect the remote power adapter and the receiver to their respective power supplies and connect
each power supply to a convenient power outlet.
1. Measure the cable run between the SR 4000 receiver and each active antenna.
2. Refer to Table 1 on page 17 to find out whether you will need to break the cable run down into sev-
eral cables and insert one or two AR 4000 antenna boosters. Table 1 states the maximum acceptable
cable lengths for RG58 and RG213 cables separately.

3. Connect an antenna cable to each antenna.
4. Referring to Table 1, connect each antenna to one or two AB 4000 antenna boosters (if necessary),
an ASU 4000 remote power adapter, and to the appropriate antenna input on the SR 4000 receiver.
5. Check that the AC mains voltage stated on the power supplies for the two ASU 4000s and the
receiver is identical to the AC mains voltage available where you will use your system. Using
the power supplies with a different AC voltage may cause damage to the unit.
6. Connect the remote power adapters and the receiver to their respective power supplies and connect
each power supply to a convenient power outlet.
For wiring examples for multichannel systems, refer to figs. 10 through 13 on page 59.
When setting up a multichannel system, remember the following points:
1. You can connect up to four SR 4000 receivers to each PS 4000 antenna splitter.
If you power both the antenna splitter and the receivers from their respective standard power sup-
plies, make absolutely sure to connect the receiver power supplies to AC power before connect-
ing the antenna splitter power supply to AC power.
Connecting the antenna splitter to power first may cause damage to the antenna splitter power
supply due to the load presented by the receivers.
2. For large systems with up to 50 channels you can daisy-chain the required number of antenna split-
ters:
• Connect the LINK outputs on the first antenna splitter to the ANTENNA IN connectors on the next
antenna splitter and so on.
• We recommend powering large systems from optional PSU 4000 central power supplies for three
antenna splitters and four receivers each.
3. Each antenna input on the antenna splitter is capable of powering a maximum of three active com-
ponents (e.g., RA 4000 B + 2 x AB 4000) via the antenna cables.
In the following cases you will need an ASU 4000 remote power adapter to power active components
(each ASU 4000 is capable of powering up to three active components, too):
• The cable run from the antenna splitter to an active component is long enough to reduce the sup-
ply voltage below the acceptable minimum.
• A device (e.g., an antenna combiner*) in the line between the PS 4000 and an active component
interrupts the DC supply voltage across the antenna cable.
* The ZAPD 21 antenna combiner from Mini Circuit feeds the supply voltage through. Similar
devices from other manufacturers may not do so.
• You have used an antenna combiner to connect two antenna lines to the same antenna input. If
you use three or more active components in one antenna line, insert an ASU 4000 remote power
adapter between the antenna combiner and the first of the active components. If the number of
active components in both lines totals more than three, be sure to insert an ASU 4000 remote
power adapter into each line. The remote power adapter prevents the antenna splitter power sup-
ply from being overloaded.
