Product description
The product is designed to support a wide range of new and existing multiswitch
installations. Each unit has:
• 4 cascadeable LNB inputs from 1 universal Quattro LNB (VL HL VH HH) or 2 Wideband LNB’s
(V & H)
• 1 cascadeable terrestrial trunk input.
• 1 level adjuster for terrestrial signals
• 4, 8, 12 or 16 SCR/Legacy outputs
• 1 DC input (for switch, line and LNB powering).
• Earth bars on the Subscriber outputs
• 5 x Quick F connectors
Each output can support a wide variety of satellite receivers :
In legacy mode, the outputs can be used as a standard multiswitch.
In SCR mode, each output supports up to 16UBs with all versions of the single cable technology.
This includes OLT, SCR, CSS, SKY UK, EN50494 and EN50607.
As all outputs are independent, the installation can be a mix of legacy and dSCR connections.
The terrestrial input supports any services that operate between 47 -790MHz, which includes
terrestrial TV, DAB and FM reception.
The trunk outputs allow the cascade of multiple switches, to support large installations.
The trunk outputs have a 75ohm self-termination toggle switch. If the Switch is the last in the
cascade, or a standalone Switch, the toggle switch can terminate the trunk outputs without
the need for 75ohm terminators.
The DC power can be inserted into the switch, on the F connector, or at any point in the system.
In cascaded systems, multiple power supplies might be required.

Please note on the 16 output
switch there are 2 x
Terrestrial adjustments. The
top potentiometer adjusts the
terrestrial output level for
subscriber outputs 1 
The potentiometer in the
middle of the switch adjusts
the terrestrial output level for
subscriber outputs 9 - 16
On the 16 output switch there
are 2 Quattro and Wideband
switches. These must both be in
the same mode. For example, if
Quattro is selected on the first
switch it must also be seleceted
on the second switch

Switch Installation
The equipment should be mounted in a well-ventilated area.
Connect the power supply to the switch, this can be done via the DC input, or via the Trunk lines. When power is
connected, a green LED on the front of the switch should be lit.
All four Satellite trunks have DC available on inputs and outputs, except if the switch is used as a terminated unit.
There is no power on the Terrestrial trunk line. All unused dSCR/Legacy (Tap) outputs should be terminated with a
75-Ohm terminator to maintain good terrestrial signals.
When a Satellite receiver is connected to the switch, power will be drawn from the Satellite receiver. The amount
of power drawn will depend on the type of receiver connected and the number of tuners selected.
All trunk outputs can be cascaded. If the switch serves as a terminated unit, turn on the switch marked “terminate
line outputs”.
Configuration of the Switch
Terrestrial amplifier
The Terrestrial trunk has an integrated amplifier, with unity gain on the dSCR output, that can be attenuated by up
to 20dB.
Satellite input
The Satellite input level to the switch, should be between 70dBuV and 100dBuV. There is no adjustment required,
as the switch has Automatic Gain Control (AGC) within this dynamic range.
Input Modes: Quattro and Wideband
The input connections on the product can be configured in either “Quattro mode” or “Wideband mode”.
When using Quattro LNBs, the toggle switch on the top right hand side of each Switch should be set in the upper
position (Quattro LNB). The Switch will then expect to receive, on each of the 4 inputs, a satellite signal from 950
to 2150MHz (Horizontal/Vertical High and Low band).
When using Wideband LNBs, the toggle switch, on the top right hand side of each Switch should be set in the
lower position (Wideband LNB). In this case, Wideband satellite signals from 290 to 2340MHz should be used
(Vertical and Horizontal).
In this mode, 2 Wideband LNBs can be connected,for signal reception from 2 orbital positions. The left Wideband
inputs V -H are the DiSEqC position “LNB A”, and the right V -H inputs are the DiSEqC position “LNB B”.

,.
Note:when using the product in wideband mode, the product will automatically make the translation between the
input frequency and the output frequency. For example a STB tunes to Horizontal High band, the product will
convert the incoming horizontal band 1290-2340MHz into the output range between 1100-2150MHz.
The same is true when using the product as a Wideband dSCR multiswitch. If the STB tunes to a Vertical Low band
channel, 1000MHz for example, the multiswitch will take the incoming vertical transponder at 340MHz and convert
to Sat IF 1000MHz and output to one of the dSCR output user bands.
The diagram above shows the basic frequency relation between wideband satellite frequencies and the standard
legacy satellite frequencies.
Output: Legacy and dSCR
Independent of the selected input mode, the outputs can support legacy and SCR/dSCR Set Top Boxes.
At start up, the Switch output works in Legacy mode and can be used as a universal, or a 2 x wideband multiswitch,
depending on the position of the toggle switch.
When receiving the first dSCR command, the unit will automatically switch into dSCR mode and supports the
following standards:

EN
Sky UK standard for SkyQ STB’s
SkyQ STB’s support 16 userbands
EN50494/SCR standard (DiSEqC 1.0)
STB’s that only support EN50494 will only be able to use the first 4 user bands.
EN50607/dCSS/dSCR standard (DiSEqC 2.0)
STBs that support the newer EN50607 will be able to use all user bands (UB1 through UB16). This is typical for new multi-
tuner STBs.
To return back to legacy mode, the output has to be reset. This can be done by removing the power from the
subscriber output, disconnecting the power from the STB.
