Purpose of Use and Special Features
These devices are intended to provide up to 8 subscribers with 4 Sat IF banks (e.g. Astra 19.2º)
and the terrestrial signal via one cable.
EN If 8 connections are insufficient, further extensions can be connected to the base unit. These will
facilitate supply to up to 24 subscribers.
The integrated Sat channel router (SCR) technology allows broadcasting without any
programming restrictions. The devices are HDTV-compatible.
It is important to ensure that the receiver is set up properly to control the TechniRouter.
All TechniSat devices with the logo “TechniRouter ready”
and receivers from other suppliers, which support the
European standard 50494
can be used. Analog receivers cannot be used.
Only use connection accessories with integrated decoupling diode.
Existing cable structures in residential buildings can be set up to receive digital satellite signals
from two satellite positions without a new cable routing.
The advantage for new installations is that many subscribers receive signals from a single
connection which makes cable installing and laying work obsolete and saves many feet of coaxial
cable.
The expansion of existing multiswitch systems is also easily possible, for instance, because of
the purchase of hard disk receivers with twin tuners.
Each user has a specific channel on the output IF band of the TechniRouter assigned (user band),
via which he, using his receiver to control, can “select” and receive his desired program.
Once the receiver has completed a successful initial configuration especially via
automatic setup, it is strongly recommended not to repeat the configuration process
due to the chance of interference with other subscribers (cf. section 4.6.2).
Please be advised that each channel can only be allocated once. Especially if 8 users are
connected to one cable that requires a certain amount of discipline, the channels initially installed
should not be impermissibly altered.
The receiver supplies the TechniRouter and the LNB with power.
If one of the connected receiver is unable to supply (symptoms see point 8), the power supply
needs to be plugged into the TechniRouter base unit. Since every receiver uses its own electronic
within the TechniRouter, it is recommended to switch this part of the device to stand-by mode, if
not in use. Following this procedure, the receiver can be switched off via its mechanical power
switch or by flipping the switch on the multiple socket outlet.
Once the last satellite receiver was switched off in the above mentioned manner, the
TechniRouter is not consuming power anymore. If only one base unit is in use, the LNBs will be
automatically turned off.
The system operates in a particular energy-efficient manner.
Should there be a need for further subscriber connections, additional distributor lines can be
made available with the help of a multiswitch accessory (see point 5).
The TechniRouter from this family are return-path-compatible.

Safety Advices
Please read the following safety notes carefully prior to assembly.
The manufacturer accepts no responsibility for damage caused by inappropriate operation or by
non-compliance with safety precautions.
•
•
•
•
•
•
•
•
•
The components must be assembled in a dry place, on a level and fire-resistant surface.
Do not cover the ventilation slits of the components.
Do not install the device within the roof insulation.
Ensure that the device is switched off when you install it.
The antenna unit must be earthed. The first device after the external unit must be connected
to the building earth.
The antenna unit must be protected against lightning strikes in accordance to relevant
requirements; please see point 4.3 for more details.
Please pay careful attention to the information contained!
The relevant European standards and VDE (Association of German Electrical Engineers)
provisions to guarantee electrical safety must be complied with.
It is necessary to comply with national law regulating broadcast receiving systems.
Never open the unit housing.
Any intervention necessary should only be carried out by specialized staff.
In the following cases, you should disconnect the unit from the mains power supply
and consult a qualified technician:
•
the unit was exposed to moisture, or liquid has run into the unit,
•
in the event of malfunctions,
•
in case of severe external damage.

Devices in the TechniRouter Family
3.1 TechniRouter 5/1x8 G (Art. No. 0000/3290) and 5/2x4G (Art. No. 0000/3292)
EN These multiswitches are used as base units for
distribution. They switch the signals from two satellite
positions (8 satellites IF banks) to up to 8 subscribers.
They make either 8 or 4 output channels (per cable) in
the IF frequency band 950-2150 MHz available. The
individual subscribers gain unrestricted access to all
digital programs.
In the satellite field, the subscriber lines have a strong
and slope-equalized amplification.
The terrestrial and the return path are passive and flat
over the frequency.
3.2 TechniRouter 5/1x8 K (Art. No. 0000/3291) and 5/2x4 K (Art. No. 0000/3293)
This cascading matrix for 8 subscribers is installed together
with a base unit (TechniRouter 9/1x8 G or 9/2x4 G) and
when used with an intermediate amplifier, up to four additional
units can be cascaded in series.
The current supply is provided from the base unit onto all
trunk cables in the cascade, in doing so its slide switch must
be in position "cascade". The current supply is passed the
cascading matrix without internal cross-linking.
3.3 Accessories
All sockets, distributors and amplifiers must be compatible for the Sat IF domain and include a DC
bypass. For wall sockets, a
DC-bypass in the trunk-line and a diode-decoupled DC-bypass in the tap must be present.
The terminal socket, likewise, must have a diode-decoupled DC-bypass too.
The DC outlet is required for the power supply for the TechniRouter and to transmit the control
signals. The diode decouples the power supplies of the receivers.
It is recommended to possibly use only one diode in the line between receiver and TechniRouter.

Installation / Setup in one- or two-family homes
Setup of small installations is easy and can be done by non-professionals.
EN
•
•
We recommend the use of a Satman 850 Plus outdoor unit, due to the exceptional
sensitivity of the TechniRouter even a smaller diameter dish is sufficient.
Use a Quattro-LNB (Low Noise Block Converter). A Quattro Switch LNB is not suitable.
Please proceed as follows:
1.
2.
3.
4.
•
•
Position the antenna with the help of a suitable measuring device or a receiver.
Install the system, ensuring the power is not connected.
Be careful to ensure that the lines from the LNB have not become interchanged with each
other. To facilitate operations, it is best to use several coaxial cables with numbering of each
individual cable or marking the relevant cables, e.g. using a suitable tack. Checking the cables
to ensure that no short circuits happened avoids time-consuming troubleshooting
procedures, especially within larger systems.
Configure the receiver as described under point 4.6.
When feeding terrestrial signals into systems with more than 8 subscribers, you should use
a preamplifier when there are problems with the RF-level.
Unused inputs must not be connected with a termination resistor!
The following detailed advantages of the system are made possible by the use of relatively
complicated technology in comparison to conventional multiswitches. To avoid seemingly
inexplicable effects, please pay attention to the setup of the distribution system following the
instructions given in point 4.6.
4.1 Upgrading an Existing Broadband Cable Distribution as an SCR Distribution
Advantage:
•
•
For the distribution itself, no new cables need to be installed. This avoids work
load, dirt and costs.
An existing coaxial cable set-up should be checked to ensure compatibility for signals of up to
2.15 GHz. The easiest way to do so is to tentatively feed in a conventional digital satellite
signal at the operating point and lift this to the furthest point via an F-plug (without the
antenna socket present), and evaluate the quality at the upper end of the band.
The sockets, distributors and amplifiers present must be replaced with satellite compatible
components with a DC connection.

We recommend at least two sockets per residence are planned.
In the example shown, the practical compatibility of the system means it makes more sense to
use two switching matrices 5/2x4. The probability of interference between participating
neighbours is lower.
4.2 Setting up a New System
Advantage:
•
•
Significantly fewer cables are required.
You do not need to construct a “star-shaped distribution”, and none of the receivers need
“their own” cables connected to a multiswitch.
Since the cable is very sensitive, you should install it at the end of the construction progress.
Where possible, use conduits for this purpose during installation. If the conduit has bends or
need to bridge long stretches, you must feed in the cable before the laying process. Ensure
there are no kinks in the cable. Do not expose to excessive tensile strain.

4.3 Earthing
The antenna must be earthed in accordance with EN 50083-1. The only exceptions are antennas,
which are more than 2 m underneath the roof edge and less than 1.5m from the building.
Warning:
EN
•
Earthing and lightning protection work should only be carried out by a trained specialist
(electrician trade).
•
Never attempt to carry out earthing and lightning protection work yourself, unless you are a
specialist with the relevant knowledge.
The following information may be used by the specialist whose services you make use of:
•
The antenna support should be positioned linearly in its shortest direction and as vertically as
possible in order to facilitate connection with the lightning protection facility of the building (if
this is not present: with the building earth).
•
Examples of a suitable earth line include a single solid wire with a minimum diameter of
2
2
2
16 mm made of copper, isolated or blank, or 25 mm aluminium isolated, or 50 mm steel,
or metallic domestic installations, provided that their diameters and durability are at least
equivalent to the requirements for an earthing line.
•
Under no circumstances should the protective earth conductor or the coaxial cable external
conductor be used for the above purpose.
•
The first device after the external unit should be connected to the building earth via 4 mm2
copper wire (e.g. with the earthed antenna support).
4.4 Expanding an Existing Sat Distribution System
Advantage:
The TechniRouter can be used together with other TechniSat multiswitches
If multiswitches are already present, it is recommended to use a cascading matrix of the
TechniRouter, which is installed at the front of the existing base unit of a multiswitch and can be
used to meet the demand for further connection points. In this case, deactivate any potential
“power save mode” of the base unit.

4.5 Cables and Plugs
•
EN •
•
•
To connect the LNB with the TechniRouter, we recommend the use of multiple coaxial
cables, 4 cables in one sheath, e.g. Multimedia cables (Art. No. 0001/3014).
To connect the TechniRouter with the antenna plug sockets, the optimal solution is the MiniCoaxSat 2150-cable (Art. No. 0001/3011), due to the amplification of the device, you may
use this slim, easily portable cable (with slightly increased loss).
To set up long cable connections with many sockets, please use the low-loss 115 dB cable
(Art. No. 0002/3107) or 120 dB premium cable (Art. No. 0001/3106).
For professional installations, TechniSat advises against the use of F plugs which are
screwed onto the cable. Only for private use, where a needed professional tool is seldom
likely to be available, screw-on F plugs may be used. If possible, buy those with a cable sheath
coupling nut.
Cables are to be stripped as follows:
7mm
Crimp connector
ca.4mm
7mm
Compression plug
6mm
Crimp quick connector
12mm
Buy your cables and plugs from your specialist dealer.
There you will also find bulk stock of cables (and advice !)
4.6 Going into Operation, Configuration
All the receivers or TV sets with satellite input connected to the TechniRouter outlet must
support SCR control conforming to EN 50494 and also be configured for this operation mode.
During the initial installation, each subscriber must have his own user band (own
frequency/channel) assigned.
Subscribers with considerable lengths of cable should get lower frequencies assigned, since the
loss from the cable and sockets will not be so severe.
34
For twin tuners (PVRs), two user bands are required.
The frequencies of the user bands are listed on page 1.
We recommend,
•
to keep these assembly instructions (and the proof of purchase) in a safe place in case of
loss, repair or new acquisition,
•
to attach a label with the user band number to the relevant receiver
(preferably on
the rear),
•
to note the locations and/or names of subscribers in the table on page 1.
Note:
A single incompatible or wrongly configured receiver (e.g. Universal LNB selected) may
disrupt the commands for all other devices connected to the same subscriber line, thus
making transmission (at least during active operation but also program changes of others)
impossible. We recommend the use of TechniPro 600-10E if multiple dwelling units need to
be supplied from the same subscriber line.
Configuring the receiver unit:
We will now outline how to configure the TechniSat receivers (see also the respective operating
instructions), although this procedure may not apply to other receivers.
Please check by referring to the operating instructions supplied with your receiving unit.
4.6.1 Initial Operation of the System
•
•
•
•
•
•
During the assignment of the user band, all other receiver units - connected to the same
output of the TechniRouter - should be switched off or even better disconnected from the
same. Otherwise this may cause malfunction of the assignment process!
To be on the safe side, initially disconnect all receiver units from the TechniRouter and
subsequently switch on and set up each one individually.
To initiate this procedure, go to the menu in the receiver or TV Settings -> Antenna
settings, enter the configuration dialog of the desired satellite position and select the LNB
type SatCR LNB.
Based on the respective receiving unit, it may now be necessary to manually enter one of the
frequencies in the configuration dialog of the SatCR as well as the relevant user band
number (channel or subscriber number, Nos. 1 to 8).
Several sat receivers offer an automatic channel search and you can subsequently select the
desired choice from a list.
If, during the above-mentioned automatic channel search, no SCR channels are found or if
the test transponder is not received, repeat the setup. Ensure, while doing so, that no other
receiver connected to the same line is currently switched on.
4.6.2 Adding of an Further Receiver during Running Operation
•
•
•
•
This procedure can only be accomplished, when one or more user band/s are still available.
Please do so at a time, when a minimal number of people are using the same subscriber line
or give the subscribers advance notice.
Switch on the receiver, but ensure the antenna cable is not connected.
Enter the menu in the receiver or TV Settings -> Antenna settings, to enter the
configuration data for the satellite orbit received and select LNB type SatCR LNB.
Now connect the antenna cable and manually enter the user band and potentially the
frequency. Automatic setup should be avoided, since this will disrupt other subscribers and
also cause malfunction of the assignment process.
35
EN
The successful assignation of the selected user band can be confirmed with the level/quality
display (toward the bottom of the on-screen display) for the adjusted test transponder. After
exiting the menu, programs can now be selected via the TechniRouter for the received satellite
EN position as with conventional receiving equipment. The user band assignment for this receiving
device is now completed.
When restarting the receiver, the SCR mode is activated from the beginning on.
4.6.3 Traffic-Indicator
The traffic indicator helps to inform you about errors.
Green LED:
•
illuminated: At least one receiver is delivering the operating voltage.
•
off:
Short circuit or overload via this output cable.
Red LED, flashes, when triggered by the receiver:
•
flashing irregularly:
At least one subscriber is changing the program
(normal status).
•
flashing regularly:
At least one receiver has not found any program.
•
illuminated continuously: The LNB type for at least one of the receivers is set up
incorrectly.
Further hints:
•
Each available channel frequency can only be assigned to one receiver at all times.
•
Within a single residence (but only there), however, with time-delayed operation and
reciprocal arrangement, the same receiving channel can be assigned to two receivers.
•
Please remain patient during the set-up process, since certain receivers are very slow.
•
After dis- and reconnecting the subscriber line to the TechniRouter or after a power
failure, it may take some considerable time until the final receiver has been able to
relocate the program last set. In this case, a single program change at one of the active
receivers may help.
•
Please terminate the terminal socket during periods of non-use with a DC decoupled
75Ω resistor.
•
Ensure amplification towards the TechniRouter (with an intermediate amplifier 5Z/NT
respectively 5Z2/NT or, based on topology, with an active splitter 5/2A) or, if necessary, at
the output of the socket
- if there are extended lengths of cable (over 70 m in total) to the subscriber,
- when there are many sockets connected in series,
- for old cables,
- when using a very small satellite dish.
You will find further information in regards to the satellite channel routing
concept in chapter 7.

Construction of Systems with More then One Cascading Units
Distribution systems for satellite and broadband cable (or terrestrial) signals with more than 24
subscribers points should only be installed by authorized specialists who are familiar with the
connection circumstances and who have a selective antenna measurement equipment.
To facilitate understanding, here are some brief details of functional operation:
Within the switching matrices, signals are handled via the directional coupler and subsequently
channelled via pin-diode-switcher to the converter circuit of the subscriber. After the conversion,
the signals are collected, amplified and merged to one cable for the subscribers. Although the
switching matrices can operate via this path with an amplification of up to 20 dB, the level within
the switching matrix is considerably lower, hence the input level of the switching matrix should not
go below 45 dBμV.
The accessories, which can be used, are specifically described in the corresponding operation
instruction:
Intermediate Amplifier 5Z/NT (Art.-No. 0000/3241) and 5Z2/NT (Art.-No. 0001/3241)
The gain and the fine-tuned slope equalization of the device
are set up to compensate loss via the cable and/or
components of 12 dB at 2150 MHz.
The gain of the terrestrial signal is adjustable.
The device is DC-supplied via all four Sat-trunks. To release
the TechniRouter base unit, you can plug in the power supply
into the 5Z/NT/ 5Z2/NT. In this case, it will supply trunk amplifier 1 and 4 plus the terrestrial
amplifier and the units in front of.
The Intermediate Amplifier is not return-path-compatible.
Passive Distributor 5P (Art.-No. 0000/3242)
With a maximum loss of 4 dB, this device is used to split the
power of the signals of all satellite IF banks and the terrestrial
signal into two outputs.
The upper outputs are not DC-transmissible, but rather is
each of the side satellite outputs exists power supplied /
connected through its satellite input.
Active Tap 5/2A (Art.-No. 0000/3243)
This component is designed to tap the signals of trunk lines
several times -twice for each device- and then to feed them into
post-switched subdivisions. The trunk lines are DC-permeable
and almost loss-free; the taps are amplified and slope-equalized.
The device itself is supplied via the tap 4, but does not feed the
trunk lines. At the trunk lines of the active tap 5/2A, a device
with a power supply must be connected at all times in order to supply the switching matrices,
amplifiers and the LNB in the trunk line.
The 5/2A is not return-path-compatible.

Table 3
Flush-Mounted Distribution Rack:
For installation in the staircase, which is the optimal arrangement for a star distribution from the
middle of the home, you should install a flush-mounted (or on-wall) distribution rack. This can also
contain, if required, an intermediate amplifier or other components. We advise that the door
should be sealed with a safety lock.
5.2 Planning
For large-scale installations a calculation of “coverage” is necessary.
This means you must consider the following points:
1.
2.
3.
4.
Power supply
Level
Isolation
Voltage drop
Be careful to ensure that the power supply to the LNB is continually safeguarded.
Satellite Range:
•
It is important (especially where many subscribers share a single cable) to ensure, that only
top quality sockets are installed.
•
Set up an assembly plan including details of all cable lengths.
•
The loss between the TechniRouter and the receiver (all cables, sockets and / or splitter)
may range from a minimum of 12 dB to a maximum of 45 dB.
•
TechniRouters have a gain of approximately 20 dB, hence do not operate with excessive
levels on the trunks - for satellite use, we recommend 70 dBμV.
•
Record the existing and required levels at the inputs and outputs of the components, see
technical data and table 1 (cable losses).
•
Note: particularly when installing more complex TechniRouter distributions, even minor
carelessness can accumulate to a large overall error.
•
Avoid overmodulation as well as going below the minimum level of the socket, see Table 3.
•
A bit error rate (BER, measured before Viterbi-decoder) better then 10-4 should be
guaranteed in each location.
•
The input signal range of the receiver (control range) is approx. 44 dBµV…84 dBμV.
•
If necessary use low loss cables and/or an amplifier, that the level of the channels at the top
end of the band do not goes below the minimal value. Due to the frequency response drop of
the LNB and cables in practice a level decline of up to 10 dB at the last socket may occur at
the top end of the band, compared with the lower end of the band.
•
Estimate the effect of any voltage drops on the feed lines to the TechniRouter. The voltage
supplied to the LNBs and for the accessories must remain at a sufficient level, for older
LNBs ≥ 11.3 V.
•
Planning with consideration in regards to level reserves helps to ensure that the system
can function properly all year around.
39
EN
Terrestrial
The devices are suitable to transmit DVB-T and DVB-C signals as well as analog signals.
•
Due to the considerable loss via the TechniRouter, sockets and output cables (tree
distribution), the input level for the DVB signal should be set to an appropriately high level.
EN
Analog signals should be set an additional 15 dB higher. The easiest solution is the use of a
terrestrial broadband antenna.
•
When the signals of the individual bands come from various directions and cost is not an
issue, we recommend the use of multiple antennas, merged together with a terrestrial
combiner (filter). Different levels can (with limitations) be adjusted to adapt to the size of the
antenna.
5.3 Installation of the Components
•
•
•
•
Lay out the cable end to end. Bad F-connector jacks can lead to a lot of interference.
For very long subscriber cables (>60 m), install a double in-wall-box after 3/4 of the length.
This way, the cable can be split later for operational integration of an intermediate amplifier.
Use the socket wrench Art. No. 0000/3407 for F-connectors. Only tighten the nuts of the
F-plug to a moderate level.
Do not use any (Insertion-) Quick-F-jacks for rapid connection.
5.4 Calibration
Verification of the Satellite Range
•
Check the output signals of the LNB, which must be flat over the frequency (< 5 dB drop off).
•
Short circuits in the subscriber line (or in the TechniRouter) can be diagnosed if the green
LED in the TechniRouter no longer lights up.
•
The configuration of the receiver is described in point 4.6.
•
Please note details of the level as well as the signal quality of the channel used. This will
considerably facilitate any possible troubleshooting that has to be conducted later.
Verification of Terrestrial
•
In the case that weak and strong broadcast stations do not come from the same direction,
try to weaken the signal of the strong broadcast through optimal positioning of the antenna
beam.
•
When receiving them from the same direction, you can use a level adjustment via one or
more good wave traps. Remember the band allocation, adjust the wave trap with an antenna
measurement device so that the small broadcast stations are hardly affected by noise.
•
For UKW feed (in a terrestrial combiner connected ahead) an attenuator may be necessary.

For Specialists: Digital Single-cable Systems according to EN 50494
7.1 How It Works
EN A problem in traditional satellite TV distribution systems is that they have to refer back to a star
distribution in order to provide each receiver with signals from all SAT IF banks. Therefore, a
coaxial cable must be installed from each receiver to the LNB or multi-switch, with TWIN
receivers even two. This makes it very costly to upgrade existing cable structures to satellite TV, if
not impossible. With a new method standardized according to DIN EN 50494 it is now also
possible to provide existing cable systems with satellite signals, without limitation to the number of
channels. In this case, each connected receiver is assigned a fixed user band.

Frequenz
Besides selecting the desired SAT IF bank, the LNB, or multi-switch, now also has the task of
converting the desired TV signal to the user band frequency.
Thus the name satellite channel router (SCR).
7.2 Control Signals
For controlling the router, special DiSEqC-related SCR commands are used. However, in contrast
to DiSEqC, the voltage is permanently 13V and is only raised to 18V during the actual command.
18V
In coordination with the receiver’s diode-separated connection, this ensures that the receiver
sending the command has exclusive access to the common cable. As introduced with DiSEqC, a
22kHz tone is modulated to transmit commands as digital data.
Each command contains the user band number as a kind of sender ID for the sending receiver.
42
SCR commands can be divided into the following groups:
Channel Change
With this command, the router will be told which SAT IF bank should
be switched to and which channel is to be converted to the user band
frequency.
PowerOff
This command prompts the router to switch off the affected user
band.
Installation
There are a number of commands meant to simplify installation of an
SCR system. Thus a receiver can query what kind of router, LNB or
multi-switch, it is connected to, and which LO frequencies are used.
The router answers with an RF signal tone within the affected user
band. In addition, the signal tones for all participants can be activated
simultaneously. This allows receivers to search for the user bands
automatically.
Because there is no bus access control in this system, there can be collisions between
commands sent by more than one receiver at the same time. This problem is solved by the
receivers recognizing the collision and repeating their commands after an ideally random delay.
7.3 PIN Protection
In distribution systems that have the cable connected to more than one dwelling (Multiple
Dwelling Units, MDU), the SCR commands can optionally be provided with a PIN code. The
command is only accepted if the PIN code matches the one stored in the router. This should
prevent, for example, a misconfiguration from having more than one receiver use the same user
band.
PIN protection can only be used if the installed router supports it. Receivers without PIN support
are usable though. However, commands with PIN codes always have priority.
TechniRouter 5/1x8 and 5/2x4 don’t have the PIN code feature.
7.4 Assembly Instruction
As far as the cabling is concerned, besides the series structure, in which all antenna outlet
sockets are on a single coaxial cable harness, tree structures, star structures and combinations
of all three are possible. The important thing is that every single receiver feeds its control
commands via a separation diode into cable sections of the SCR bus shared with other receivers.
This, in combination with the bus voltage being raised to 18V during SCR commands, is the only
way to ensure that these arrive at the router and are detected within.
Generally, antenna outlet sockets with integrated separation diodes have to be installed.
If one connects multiple receivers to a shared antenna outlet socket, distribution elements with
diode-separated DC paths must be provided.
In contrast to omitted separation diodes, multiple cascaded diodes don't generally impair the
system's functionality. However, in router installations not utilizing an external power supply
attention has to be paid to the resulting lower bus voltage due to voltage drops at the diodes,
whether it is still sufficient for stable operation of router and LNB.
43
EN
7.5 Known Problems
•
EN •
•
•
•
•
A misconfigured receiver, installed on universal LNB and horizontal polarization
(corresponding to 18V), prevents all communication on the SCR bus.
If more than one receiver is set for the same user band, constant channel change
commands might be observed if these receivers are operating at the same time.
Automatic searches for the user bands interrupt TV reception in case of other connected
receivers.
Conversely, automatic searches are also disturbed by receivers that are currently in
operation, because the receivers react with a new tuning command if the RF tone is
switched on and thereby turn it off again.
If distribution equipment without diode-separated DC paths is used, a receiver’s SCR
commands can be so weakened that the satellite channel router doesn’t recognize them
anymore.
After a power outage, receivers of the same construction can send SCR commands in the
same rhythm, causing lasting collisions.
