2.3 Optional Accessories

The PS 4000 W is an antenna splitter for setting up UHF multichannel systems with up to four receivers per antenna splitter. (Note that the number of channels you can actually operate simultaneously depends on local frequency plans.)

The PS 4000 W features two rear panel antenna inputs for connecting SRA 2 B/W or RA 4000 B/W active antennas with built-in boosters. Each antenna input provides a 12 VDC supply voltage for powering up to three active antenna components, e.g., one active antenna and two AB 4000 antenna boosters. Also located on the rear panel are two sets of four antenna output connectors for up to four diversity receivers and two additional antenna outputs for feeding the antenna signal to several additional PS 4000 W antenna splitters.

The PS 4000 W is housed in a 1 U, half-rack case so you can mount two antenna splitters in a single rack space.

The PS 4000 W can be powered from an optional local power supply. For systems with more than four channels, we recommend using an optional PSU 4000 central power supply for three antenna splitters each.

Both the antenna boosters and the antenna splitter are wideband devices for the entire UHF band.

The antenna splitter front panel provides the following controls and indicators:

ON/OFF: Press this key to switch power to the unit ON. Press again to switch power to the unit OFF.

ANTENNA A, ANTENNA B: The blue OK LED will be lit for as long as the ANTENNA A IN/ANTENNA B IN input provides the correct supply voltage for active components.

Should the supply voltage at an input be shorted or fail (drop below 2 V) the OK LED for that input will extinguish and the red ERROR LED be lit instead.

• The two OK LEDs do NOT indicate the operating status of the connected antenna booster and therefore will not go out when you disconnect an antenna cable.

CLA: The round plate with the AKG logo covers a bank of three DIP switches for matching the antenna inputs (ANTENNA A IN, ANTENNA B IN) to the length of the connected cable run.

Fig. 2: PS 4000 W rear panel.

The PS 4000 W rear panel provides the following inputs and outputs:

DC IN 12 V/2A: Input jack for an optional 12 VDC power supply or optional PSU 4000 central power supply.

ANTENNA A IN, ANTENNA B IN: BNC input connectors for SRA 2 B/W, or RA 4000 B/W remote antennas. When using diversity receivers you will need two receiving antennas (optional). Each antenna input provides a 12 VDC supply voltage for an active antenna.

ANTENNA A OUT TO SR: The four BNC connectors 1A through 4A deliver the antenna signals for the A inputs of up to four diversity receivers. All unused outputs are electrically terminated automatically.

ANTENNA B OUT TO SR: The four BNC connectors 1B through 4B deliver the antenna signals for the B inputs of up to four diversity receivers. All unused outputs are electrically terminated automatically.

In addition to the antenna signals, outputs 1A through 4A and 1B through 4B provide a 12 VDC supply voltage for the connected receivers.

• The only way to ensure that outputs 1A through 4B/Will provide sufficient current to power the connected receivers is to connect the antenna splitter to an optional PSU 4000 central power supply.
• If you power the PS 4000 W antenna splitter from an optional local power supply, make sure to power each receiver from a local (optional) power supply, too. If you connect receivers to the antenna splitter without connecting each receiver to a power supply and AC power, the antenna splitter's standard power supply may be damaged due to overload.
  LINK A TO PS, LINK B TO PS: These two BNC outputs carry the RF signal of the two antennas A and B. You can connect the LINK outputs to the antenna inputs of another PS 4000 W antenna splitter to daisy-chain several antenna splitters. Note that you will need one optional PSU 4000 central power supply each to power three PS 4000 W antenna splitters.

See also Wiring Diagrams figs. 10 through 13.

2.5 PSU 4000 Central Power Supply (optional)

The PSU 4000 central power supply delivers a 12 VDC, 2 A secondary voltage for powering three PS 4000 W antenna splitters and the receivers (12 max.) connected to the antenna splitters. For details refer to the PSU 4000 user manual.

2.6 Receiving Antennas (optional)

Passive and active directional antennas as well as passive and active omnidirectional antennas are available for the PS 4000 W antenna system. All antennas are wideband devices for the entire UHF band. The active antennas are powered by the PS 4000 W antenna splitter via the antenna cables. For complex systems with long antenna cables, we recommend powering each active antenna from a PSU 4000 central power supply via an ASU 4000 remote power adapter.

2.6.1 SRA 2 B/W

The SRA 2 B/W is an active directional antenna with a rugged, water-resistant case designed specifically for indoor and outdoor use at a distance from the performance area. An integrated high-performance antenna booster allows you to position the antenna up to 100m (330 ft.) away from the receiver. Using RG213 antenna cables and two AB 4000 antenna boosters in series, you can set up the SRA 2 B/W even 200m (660 ft.) away from the receiver. The antenna provides a BNC output, status LED, and integrated stand adapter.

2.6.2 RA 4000 B/W

The RA 4000 B/W is an active omnidirectional antenna with a rugged, water-resistant case designed specifically for indoor and outdoor use in close proximity to the performance area. An integrated high-performance antenna booster allows you to position the antenna up to 100m (330 ft.) away from the receiver. Using RG213 antenna cables and two AB 4000 antenna boosters in series, you can set up the RA 4000 B/W even 200m (660 ft.) away from the receiver. The antenna provides a BNC output, status LED, and integrated stand adapter.

3.3 Setting Up Antennas

The following hints on placing antennas apply to both single-channel and multichannel systems with any number of channels.

3.3.1 Placement

Reflections off metal parts, walls, ceilings, etc. or the shadow effects of musicians and other people may weaken or cancel the direct transmitter signal. For best results, place the antennas as follows:

1. Place the antennas near the performance area (stage). Make sure, though, that the transmitter will never get any closer to the antennas than 16 ft. (5 m). Place the two antennas at least 8 inches. (20 cm) from each other.
2. There should always be a direct line of sight between the transmitter and antennas.
3. Place the receiver at least 5 ft. (1.5 m) away from any big metal objects, walls, scaffolding, ceilings, etc.
4. Do not place antennas in wall recesses.
5. Place antennas at least 5 ft. (1.5 m) away from any equipment that may emit RF radiation such as lighting racks, fluorescent lamps, digital effects units, or PCs.
6. If you set up two antennas side by side (e.g., for diversity reception), check that the two antennas are spaced at least 20cm (8 in.) apart.

3 Getting Started

3.3.2 Mounting Antennas on Floor Stands

When mounting the antennas on floor stands, be sure to proceed as follows:

1. Use the supplied SA 63 or the integrated stand adapter to mount the antenna on the boom of a boom stand.
2. Pull the boom out all the way to one side to make sure the antenna will be at least 28 inches (70 cm) away from the stand.
3. Extend the stand high enough to place the boom at least 6 ft. (1.8 m) above the floor.
4. Wind the antenna cable around the boom. Do not allow the cable to sag below the boom because this may degrade the reception quality.

Fig. 3: Antenna mounted on floor stand

If you mount your antennas on a wall or ceiling, be sure to keep the following minimum distances:

1. Mount the antenna at least 10cm (4 in.) in front of and at a minimum lateral distance of 50~cm (20 in.) from any walls or other plane surfaces, metal grids, or metal scaffolding.

Fig. 4: Minimum distances from plane surfaces.

1. Make sure the antenna will sit at least 15cm (6 in.) above the floor or 50~cm (20 in.) from the ceiling (or 15cm (6 in.) if you route the cable to the antenna from above).

For a single-channel system, you need no antenna splitter. Connect the antennas to the receiver directly.

Fig. 5: Minimum distances from floor and ceiling.

1. Measure the cable run between the receiver and each antenna.
2. Refer to Table 1 on page 17 to find out whether you will need to break the cable run down into several cables and insert one or two AB 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 the antennas to the antenna inputs on the 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 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 adapter and the receiver to their respective power supplies and connect each power supply to a convenient power outlet.

7. Measure the cable run between the receiver and each active antenna.

8. Refer to Table 1 on page 17 to find out whether you will need to break the cable run down into several cables and insert one or two AR 4000 antenna boosters. Table 1 states the maximum acceptable cable lengths for RG58 and RG213 cables separately.
9. Connect an antenna cable to each antenna.
10. 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 receiver.

Refer to Table 1 on page 17 and fig. 7 on page 16.

3 Getting Started

Fig. 7: Wiring a single-channel system with active antennas and different antenna cable runs.

3.5 Multichannel Systems with PS 4000 W Antenna Splitters

1. 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.
2. 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 56.

When setting up a multichannel system, remember the following points:

1. You can connect up to four receivers to each PS 4000 W antenna splitter.

• If you power both the antenna splitter and the receivers from (optional) local power supplies, make absolutely sure to connect the receiver power supplies to AC power before connecting 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.

• For large systems with up to 50 channels you can daisy-chain the required number of antenna splitters:

• 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.

• Each antenna input on the antenna splitter is capable of powering a maximum of three active components (e.g., RA 4000 B/W + 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 supply voltage below the acceptable minimum.

• A device (e.g., an antenna combiner*) in the line between the PS 4000 W and an active component interrupts the DC supply voltage across the antenna cable.

Note:

• 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 supply from being overloaded.

3.6 The CLA Switch Bank

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.

Refer to Table 1 on page 17.

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.
