Hej

 

Har hittat högtalare (Tangent Evo E4L) som passar mitt rum men det står 4 till 8 ohm på dem och råkade se nedan på förstärkarens (Denon AVR-3806) manual. Vågar jag köpa dessa?

2 Speaker impedance
• Speakers with an impedance of from 6 to 16
Ω/ohms can be connected for use as front,
center, surround and surround back speakers.
• Be careful when using two pairs of surround
speakers (A + at the same time, since use
of speakers with an impedance of less than 8
Ω/ohms will lead to damage.
• The protector circuit may be activated if the
set is played for long periods of time at high
volumes when speakers with an impedance
lower than the specified impedance are
connected.
Protector circuit
This unit is equipped with a high-speed
protection circuit. The purpose of this circuit
is to protect the speakers under circumstances
such as when the output of the power
amplifier is inadvertently short-circuited and
a large current flows, when the temperature
surrounding the unit becomes unusually
high, or when the unit is used at high output
over a long period which results in an
extreme temperature rise.
When the protection circuit is activated, the
speaker output is cut off and the power
supply indicator flashes. Should this occur,
please follow these steps: be sure to switch
off the power of this unit, check whether
there are any faults with the wiring of the
speaker cables or input cables, and wait for
the unit to cool down if it is very hot.
Improve the ventilation condition around the
unit and switch the power back on.
If the protection circuit is activated again
even though there are no problems with the
wiring or the ventilation around the unit,
switch off the power and contact a DENON
service center.
Note on speaker impedance
The protector circuit may be activated if the
set is played for long periods of time at high
volumes when speakers with an impedance
lower than the specified impedance (for
example speakers with an impedance of
lower than 4 Ω/ohms) are connected. If the
protector circuit is activated, the speaker
output is cut off. Turn off the set’s power,
wait for the set to cool down, improve the
ventilation around the set, then turn the
power back on.

Hej, borde inte vara något problem då man specat 2*210W (4ohm) dynamic power.

Sedan brukar den specade impedansen vara en nominell angivelse och med en så knepig angivelse som 4 till 8 Ohm borde detta betyda att den nominella impedansen ligger i trakten kring 6Ohm och att impedansen aldrig går under 4 Ohm eller över 8 Ohm.

 

Ser inte varför man skulle ange två impedanser om de inte utgör någon form av gränsvärden.

Hej

 

Aha låter vettigt! Tackar o bugar för snabb kommentar!!

 

Tyvärr fick jag inte att receivern att funka idag  verkar som om HDMI in är trasig så kanske köper receivern killen hade oxå
