Unpacking the ECI 4

Immediately upon receipt of the ECI 4, inspect the carton for possible damage during shipment.

The carton and packaging have been designed to provide the safest possible protection for

transport of your integrated amplifier. Unpack the unit carefully. Save all packaging materials

for future shipment.

The contents of the carton

1 pcs Electrocompaniet ECI 4 integrated amplifier.

1 pcs AC main cord.

1 pcs spare main fuse (located in the fuse drawer).

1 pcs inspection card.

1 pcs remote control.

2 pcs batteries.

Set up procedure

Before connecting the ECI 4 to the mains, check that the main voltage indicated on the rear

panel corresponds to the line voltage in the territory were you intend to use the unit.

How to avoid damages

Do not under any circumstances connect or disconnect equipment when power is turned on.

The design of the RCA plug generates a huge transient when inserted. Connecting or dis-

connecting equipment with the power on can result in severe damage to both speakers and

amplifier.

How to avoid noise problems

The ECI 4 contains delicate circuits that are sensitive to magnetic strayfields. The unit should

not be placed near mains transformers, TV sets etc. Care should also be taken regarding

placement of the interconnect cables. Do not run interconnect cables in parallel with main

cords or speaker cables. Keep interconnect cables as short as possible.

How to avoid possible antenna problems

In some set-ups hum may occur when you connect the radio, VCR or TV to your system.

The problem is caused by DC voltage coming from your antenna. Please contact your cable

network operator.

How to connect your system

Please read this page carefully and follow diagram 1, page 14.

Gain switch

On the rear panel you will find a switch to adjust the gain in the amplifier. Use this switch to

accommodate the signal source to the amplifier. This switch will also affect the HT input.

Balanced XLR input and operation:

The balanced mode can only be used if the signal source has a balanced output. Use an

XLR interconnect with GND on pin 1, + on pin2, and - on pin 3. To use the balanced input

single ended, connect the ECP5XLR in the XLR

Single ended RCA input and operation:

The left channel is the top row on the rear, marked black. All inputs are similar regarding

sonic performance. Unused inputs may be shorted to ground, using a RCA shorting plug.

HT (Home Theatre)

Is a direct input where the volume potentiometer is bypassed. ECI 4 will work like a power-

amplifier with fixed gain.

REC. outputs are used for recording.

The source you listen to will be monitored through this output. The record output is not

influenced by the volume control setting, but will be shut off by the MUTE function. Never use

shorting plugs in outputs.

PRE OUT:

The pre out is dependent by the volume control setting, and MUTE function. These outputs

(balanced and single ended) can be used to control an additional power amplifier. If more

than one amplifier is used, and these amplifiers are DC coupled on the input side, they will

influence on each other when the amplifiers are switched on/off. To avoid any problem, these

amplifiers must be turned on/off simultaneously. Never use shorting plugs on the outputs.

Speaker output:

Never short the positive output to ground or chassis.

Switch the amplifier off when connecting the speakers.

How to power up your system

You should always power up your system the following way:

Signal sources (CD player, tuner etc.) first.

Allow a 30 seconds warm-up before you turn on the ECI 4.

When switching off your system:

Start with the ECI 4, then the signal sources.

Replacing a blown main fuseDiagram 5, page 15

The main fuse is located in a small drawer inside the AC inlet of the unit. If, for some reason

the fuse is blown, turn the unit off, and remove the AC cord from the AC inlet. Open the

drawer with a small screwdriver and remove the blown fuse. The spare fuse is located inside

a holder in front of the main fuse.

1. Remove the spare fuse gently by pushing it sideways out of its holder.

2. Insert the spare fuse as the active fuse.

3. Push the drawer gently back to closed position.

4. Re-insert the AC cord and turn the unit on.

Never replace the fuse with other values than indicated on the unit!

Replacing remote control batteries Diagram 4, page 15

Replace used batteries by gently inserting your fingernail or small screwdriver in the

groove on the left side of the battery compartment cover. Lift the cover off, and insert a

fresh set of batteries. Be careful to follow the + and - polarity indications at the bottom of

the battery compartment.

Important Notice

For optimal sonic performance, the ECI 4 should be burned in for a minimum time of 72

hours. The easiest way to burn in your ECI 4 is to put a signal at any input, without the

speakers connected In daily operation, switch off the ECI 4 by using the MUTE button on the

remote control. If the ECI 4 has been switched off, allow two hours of warm-up to optimal

sonic performance. Due to high class A operation in all Electrocompaniet designs, it is nor-

mal for the ECI 4 to feel warm. Proper ventilation is important. The amplifier is fan cooled. It

is important that there is at least 3-5 cm (1-2inches) of air on the left side of the amplifier and

5-8 cm (2-3 inches) above. Never cover the ventilation area.

Pakke ut ECI 4

Etter du har mottatt ECI 4 bør du inspisere esken for skader som kan ha oppstått under

transport. Innpakningen er laget for best mulig å unngå skader på produktet under trans-

port. Pakk ut apparatet forsiktig. Spar på innpakningen for senere bruk.

Eskens innhold

1 stk Electrocompaniet ECI 4 integrert forsterker

1 stk Nettledning

1 stk Reservesikring (ligger i sikringsskuffen bak på apparatet.)

1 stk Inspeksjonskort

1 stk Fjernkontroll

2 stk Batterier

Før du kobler til

Før du kobler apparatet til nettet bør du sjekke at nettspenningen i området du befinner deg

i stemmer overens med spenningen som er markert bak på ECI 4.

Hvordan unngå skader

Du bør ikke under noen omstendigheter koble til eller fra kabler eller utstyr mens ECI 4

står på. Utformingen av RCA kontakten forårsaker en stor transient når den kobles til. Til

eller frakobling av utstyr når ECI 4 står på, kan forårsake skader på både ECI 4 og høytta-

lere.

Hvordan unngå støy

ECI 4 har elektronikk som er følsomt for magnetfelt, så apparatet bør ikke plasseres i

nærheten av transformatorer og tv apparater. Ta også hensyn til hvor du legger signal-

kablene. Disse bør ikke ligge parallelt med nettkabler og høyttalerkabler. Du bør også

holde signalkablene så korte som mulig.

Hvordan unngå mulige antenne problemer

I noen tilfeller kan det oppstå brom når du kobler forsterkeren til tv eller video. Dette kan

være forårsaket av en DC spenning som kommer fra antennekabelen. Kontakt din kabel

leverandør for løsning av dette problemet.

Hvordan koble opp ECI 4

Les og følg diagram 1 side 14

Nivå bryter

På ECI 4s bakpanel finner du en bryter for justering av forsterking. Bruk denne bryteren for

å tilpasse ECI 4 til dine signalkilder. Bryteren har også innvirkning på HT inngangen.

Balansert XLR

Du kan bare gå balansert om du har en signalkilde med balanserte utganger. Bruk en

signalkabel med jord på pinne 1, pluss på pinne 2 og minus på pinne 3.

Om du skal bruke den balanserte inngangen med en single kilde, må du koble i mellom

en overgangsplugg (ECP5XLR).

Single

Øverste rad med RCA kontakter merket med svart er innganger for venstre kanal. Alle

innganger har lik lyd og nivå egenskaper. Ubrukte innganger kan kortsluttes med en

kortslutnings plugg.

HT(home theatre)

HT er en direkteinngang hvor volum kontrollen er koblet bort. ECI 4 vil virke som en effekt

forsterker.

REC utganger

REC utgangene er brukt for opptak. Utgangene vil alltid ha samme signal som kilden du

lytter til. Volum kontrollen har ingen innvirkning på disse utgangene, men vil bli koblet fra

ved bruk av Mute funksjonen. Bruk aldring kortslutningsplugger i noen av utgangene.

Pre Out

Utgangene er påvirket av volum kontrollen og mute funksjonen. Disse utganene (balansert

og singel) kan brukes til å styre en ekstra effektforsterker. Om flere effektforsterkere er

koblet sammen, og disse forsterkerene er DC koblet på inngangssiden, kan de påvirke

hverandre når de blir skrudd av og på. Du kan unngå dette ved å skru forsterkerene på /av

på likt.

Bruk aldri kortslutnings plugger på utgangene.

Høyttaler utganger

Kortslutt aldri den positive utgangen til jord eller chassis. Skru alltid av forsterkeren når du

kobler til / fra høyttalerene.

Hvordan skru på

Du bør alltid skru på i følgende rekefølge.

Start med signalkilder (cd-spiller, radio etc.) Vent gjerne 30 sekunder før du slår på ECI 4.

Hvordan skru av

Start med ECI 4, deretter signalkildene.

Diagram 2 side 15

Hovedstrømbryter finner du i senter av fronten. Ved daglig bruk kan du skru ECI 4 av ved

å bruke mute knappen på fjernkontrollen. Skal ikke forsterkeren brukes over lengere tid,

bør du slå av med hovedbryteren. Fjern gjerne nettledningen for sikkerhets skyld. Om ECI

4 har vært avslått over lengere tid, kan det ta et par timer før lyden er optimal.
