Lets take these one at a time.......

Any source in the Main System can be distributed to any Room, simultaneously.

As opposed to a standard Line Driver based Knekt system where the Main System pre-

amp RECORD output is distributed to all Rooms, the Intersekt enables the distribution

and control of up to 16 sources to any Room simultaneously.

When accessing a source which is already being listened to (in another Room ) the RCU

will inform the customer, not bad eh ?

Contents

Main System sources can be controlled independently.

A Line Driver based system transmits all control commands to ALL Main System sources,

e.g. a [ PLAY ] command will be sent round the entire Linn Line Remote Loop AND

echoed from each IR repeater output.

This will only present a problem if a customer has, for example, 2 Kremlin tuners or 2

generic RC5 CD players or 2 VCR’s.

( Remember: In a Line Driver based Knekt system a Linn AND a non RC5 source of

the same type will not have this particular problem. e.g. a Karik and a Pioneer CD

player ).

With an Intersekt, each source is controlled independently: commands for Tuner 1 are sent

ONLY to Tuner 1, commands for Tuner 3 are sent ONLY to Tuner 3. Each source input

on an Intersekt has a corresponding set of control i/p o/p sockets.

For a Linn source, commands are sent and status is read back via two phono sockets

connected to the Linn Line Remote sockets on each individual Linn source.

For a non-Linn source, commands are sent via one phono socket (and a phono to 3.5mm

adapter ) to the IR repeater for that particular source.

The wee adapter....

RS part nr 177-734 app 47p

Tandy ( Radio Shack ) have them as well.

Contents

Individual Rooms can be allocated certain sources.

Up to Installation software V1.03.

With a Line Driver system all Main System sources are available in all Rooms. You could

determine the amount of control over each source but ALL sources can be ‘listened to’.

Installation software V2.00: Introduced with the Intersekt.

Main System sources can, in effect, be ‘unplugged’ from individual Rooms. This allows

the customer to determine in which Rooms, for example, the Karik CD player can be

accessed and listened to.

Contents

Main System sources can be situated remotely from the Main System pre-amp.

This is the one that seems to cause a certain amount of confusion so a diagram of each of

the configurations is included.

The main thing to remember is.....

1. To have Intersekt ‘in parallel’ with the Main System pre-amp AND have control of the

Main System pre-amp functions from the Main System RCU then that pre-amp MUST

be a Linn Kairn.

2. To have a ‘Phantom’ Main Room, i.e. all the sources and the Intersekt in a cupboard

under the stairs then the Main Room becomes ‘just another Room’.

Why MUST the Parallel system have a Kairn ?, well...... It’s all down to the electronics

within the respective pre-amps.

A Kairn will respond to pre-amp commands from the Linn Line Remote input.

A Wakonda/Majik does NOT have any Linn Line Remote sockets or circuitry.

When a Sneaky Receiver is installed in a Wakonda/Majik the Linn Line Remote sockets

are for comms with local Linn sources.

The Wakonda/Majik will NOT respond to pre-amp commands from the Linn Line Remote

sockets on the Sneaky Receiver.

( The Wakonda/Majik with a Sneaky Receiver responds to pre-amp commands via

the RJ45 socket, i.e. the RCU ).

Expandable - up to 16 sources distributed to up to 128 Rooms.

The Intersekt ‘boxes’ come in three configurations....

1. Intersekt R8S8a STANDALONE box that will distribute 8 sources to up to 8

Rooms. This box is NOT expandable, it is a one off solution for customers who will

NEVER have a requirement to exceed the 8x8 limit.

2. Intersekt SES8a Source Expansion box that can accommodate up to 8 sources.

There is a maximum of 2 SES8 expansion boxes per system allowing up to 16 sources.

3. Intersekt RER16 a Room Expansion box that can distribute to up to 16

Rooms. A maximum of 8 RER16 expansion boxes can be linked to allow up to 128

Rooms.

In the Hints and Tips section at the end of this document you will find various System

options depending on whether the customer has a ‘Phantom’ or ‘Parallel’ Intersekt and

whether he has 1 or 2 RECORD devices.

On the next two pages you will find layouts for each of the ‘boxes’ and a 16 source 32

Room setup.

Designated Rooms can have Volume control over another Room or Rooms

During the installation of an Intersekt system Rooms can be allocated to a GROUP or

GROUPS, and within a GROUP certain Room RCU’s can be specified as having Volume

control over ALL other Rooms in that GROUP.

What does it all mean ?

Well,

if, at installation, the RCU in the Kitchen was allocated Volume control over all the

Rooms downstairs then when the phone rings the customer can turn down the volume in

all those Rooms.

or,

from the bedroom the customer could turn down the volume in all the kids bedrooms

when it was time for sleep.

What the final volume limit is set too ( as a % of maximum ) will remain the maximum

allowable in all the ‘other’ Rooms in that GROUP.

When the volume in a Room or GROUP of Rooms is above that set by the designated

RCU the volume in that Room or GROUP of Rooms will reduce automatically to the new

maximum.

When the volume level is re-adjusted to a higher level the volume in the Room or GROUP

of Rooms will remain as is until the individual RCU in that Room or GROUP of Rooms is

adjusted.

Pretty trick eh ?

Contents

Designated Rooms can access Record functions in the Main system.

The Record functions of the Main System VCRs or Tapedecks can ONLY be accessed by

the RCU’s allocated that facility at system installation.

At present, this facility can present you with a few potential ‘funnies’......... read on....

R8S8 has 1 Room expansion card.

RER16 has 2 Room expansion cards.

Each Room expansion card has 8 Room RJ45 sockets and 2 sets of RECORD output

phono sockets.

In the Installation software (V2.00 onwards) , when you install a RECORD device, a VCR

or a Tape Deck, one of the Room outputs, Room 1 or Room 2, will be allocated to that

RECORD output. Therefore you will LOSE one Room for each RECORD device.

This could present a potential problem that you must be aware of.......

In a Phantom Intersekt system, with 2 RECORD devices, there wont be a problem as long

as the first ‘Room’ is Room 3.

In a Parallel Intersekt system, i.e. a Kairn AND a Main System RCU, Room 1 is allocated

by default. Therefor, at present, with this configuration, an Intersekt R8S8 system will

only allow 1 RECORD device, which MUST be allocated to Room 2.

In an RER16 situation the problem would only appear if the customer wished to access

the RECORD functions of 4 devices.

For the next Installation Software revision, when you install a RECORD device you will

be given the option of accessing the RECORD functions of VCRs and Tapedecks. If you

decide NOT to access the RECORD functions then the record outputs will NOT use up a

Room output.

You can allocate a RECORD device to a Room Interface that does NOT exist - eh ?

In an 8x8 you have only 1 Room interface card so if you allocate the RECORD

device to Room Interface 2 Room 1 then you will retain access to Room Interface 1

Room 1.

We do try.

Contents

Global Clock updates to all RCU’s.

In a 128 Room Intersekt system it would be a bit of a job to go round all 128 Rooms and

update each RCU clock when the clocks change twice a year !!!!

With Intersekt, when the clock is changed on an RCU the customer is invited to send the

new TIME to ALL RCU’s in the system.

Contents

Switch off the entire Knekt system from one RCU.

There is a facility, with Intersekt, that will power off the entire Knekt system. To actually

disconnect power from the whole system each Room would require a Relay Boks. If there

is no Relay Boks then the Power Down command will put every Room into ‘MUTE’ by

turning all RCU’s in the Knekt system ‘off’.

Press and HOLD the ON/OFF switch on the RCU. The RCU display will count down, 5-

4-3-2-1, and shutdown the full system (Disconnect all sources from ALL rooms!).

There is NO global power on facility. Each Room will revert to it’s previous state when

that Room’s RCU is switched ‘on’.

Switching ON the Intersekt.

With an Intersekt system with RER16 and SES8 make sure that you switch on the SES8

FIRST. Otherwise the SES8 doesn’t now what Sources are IR controlled, it assumes that

every source is a Linn source (which it should be guv!).

Switching OFF the Intersekt system.

Make sure that every RCU is in Stand-by mode. If the RCU is getting a Source STATUS,

the Intersekt is too busy waiting for the RCU to finish it’s task and sometimes doesn’t

have enough time to go into Standby itself. This can cause the Intersekt to loose its

memory and has to be re-setup

Other Stuff - hints and tips.

Linstall V2.00 HELP - with the Linstall software loaded onto your screen hit [ F1 ] for

some useful help information. Look at the [ problem systems ] page for details on

downloading to individual RCU’s from DOS - very useful in an Intersekt system where

one RCU ( three miles away ) won’t download successfully.

For configuring the Intersekt within Linstall have a look in Knektips.doc

Kairn in a Parallel Intersekt System.

Communication between the Main System RCU and the Main System Kairn are via the

Linn Line Remote sockets of Source 1 on the Intersekt. The Main System RCU should be

connected to the RCU RJ45 socket of Room 1 on the Intersekt.

When installing a Kairn in parallel with an Intersekt, you MUST remember to connect the

sources to the Intersekt in the same order as they are connected to the Kairn.

Linstall

Interface Position:

This box is only shown in an Intersekt system. It is to tell the Intersekt what RCU

is connected to which Room socket.As an Intersekt system can be have upto 128

room it has to now what room is what RCU.

The large (first) box is the ID of the Intersekt board. A Intersekt R8S8 has only 1

board, but a Intersekt RER16 has 2 boards. Rooms1-8 could be on Board1 and

Rooms 9-16 on Board2. You can call the board numbers any value from 1 to 16,

as long as you know what RCU is connected to what board!

The smaller (second) box is the room number on that board. This number can only

be from 1 to 8, as you can only have 8 rooms per board.

E.g.

28 room system with 8 sources:-

2 x RER16 and 1 x SES8.

First RER16 has rooms 1-16

Room1- Interface position 1 1

Room2- Interface position 1 2

......

Room7- Interface position 1 7

Room8- Interface position 1 8

Room9- Interface position 2 1

Room10- Interface position 2 2

......

Room14- Interface position 2 6

Room15- Interface position 2 7

Room16- Interface position 2 8

Second RER16 has rooms 17-32 (only 28 rooms used)

Room17- Interface position 3 1

Room18- Interface position 3 2

Room19- Interface position 3 3

.....

Room27- Interface position 4 3

Room28- Interface position 4 4

Room29- Interface position 4 5

Room30- Interface position 4 6

Room31- Interface position 4 7

Room32- Interface position 4 8

Contents

When Loading the RCU’s the Linstall tells you to connect the Room Interface 1. If it find

that Room Interface 2 is connected, it asks if you want to re-name this as Room Interface

The Intersekt Room Interface boards can be re-named, as long as the RCU’s serial No’s in

the Linstall are connected to the Room Interface board number. Otherwise everything will

get confused.

Interface position with Tape or VCR sources.

When you install a RECORD device you will be given the option of accessing the

RECORD functions of VCRs and Tapedecks. If you decide NOT to access the RECORD

functions then the record outputs will NOT use up a Room output.

You can allocate a RECORD device to a Room Interface that does NOT exist - eh ? In an

8x8 you have only 1 Room interface card so if you allocate the RECORD device to Room

Interface 2 Room 1 then you will retain access to Room Interface 1 Room 1. (The

maximun Room Interface Number is 15).

Controlling 58kHz Devices with an Intersekt system.

For some of the Satelitte recievers, it is necessary to output with a IR carrier frequency of 58kHz. The

extra equipment required is a Knekt Line Driver and a Doubri (RJ45 to Phono Convertor).

Conversion of the Line Driver.

The following change below is required:-

1. Short out R302.

2. Bridge resistor R301 with a resistor of 470Ω.

3. Adjust Vr301 for approx 58kHz, (U301 pin 3). This step done while transmitting the code.
