4) Referring to Table 1, connect each antenna to one or two AB4000 antenna boosters (if
necessary), an ASU4000 remote power adapter, and to the appropriate antenna input on
the receiver.
5) Check that the AC mains voltage stated on the power supplies for the two ASU4000 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.
Using the power supplies with a different AC voltage may cause damage to the unit.

Multichannel Systems with APS4 Antenna Splitters

For wiring examples for multichannel systems, refer to figs. 8 and 9 from page 65.
When setting up a multichannel system, remember the following points:
1) You can connect up to four receivers to each APS4 antenna splitter.
2) For large systems with up to 50 channels you can daisy-chain the required number of
antenna splitters:
3) Each antenna input on the antenna splitter is capable of powering a maximum of three
active components (e.g., RA4000 B/W + 2 x AB4000) via the antenna cables. In the
following cases you will need an ASU4000 remote power adapter to power active
components (each ASU4000 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 supply voltage below the acceptable minimum.
 A device (e.g., an antenna combiner*) in the line between the APS4 and an active
component interrupts the DC supply voltage across the antenna cable.
The ZAPD21 antenna combiner from Mini Circuit feeds the supply voltage through. Similar
devices from other manufacturers may not do so.
NOTE
 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 ASU4000
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 ASU4000 remote power adapter into each line. The remote power adapter
prevents the antenna splitter power supply from being overloaded.
CLA-Cable Length Adjustment
The RF signal level at each antenna input on the antenna splitter(s) depends on the frequency
band, antenna type, cable type, and cable length.
To ensure optimum signal level at the antenna input, set the CLA switches on each antenna
booster and on the antenna splitter(s) as shown in Table 1 below.
1) Remove the cover of the CLA switch bank.
2) Set the three DIP switches as required for your frequency band, antenna model, cable
type, and cable length.
3) Replace the cover.
