Speciﬁcations

Connecting the Speaker Cables

Carefully check the left (L) and right (R) channels and + (red) and –

(black) polarities on the speakers being connected to the AVR-1909,

and be sure to interconnect the channels and polarities correctly.

Peel off about 0.03 ft/10 mm of sheathing

from the tip of the speaker cable, then

either twist the core wire tightly or

terminate it.

Turn the speaker terminal

counterclockwise to loosen it.

Insert the speaker cable’s core wire to

the hilt into the speaker terminal.

Turn the speaker terminal clockwise to

tighten it.

When using a banana plug

Tighten the speaker terminal ﬁrmly before

inserting the banana plug.

NOTE

• Use speakers with an impedance of 6 to 16 Ω/ohms. When using

front A and B speakers simultaneously, use speakers with an

impedance of 12 to 16 Ω/ohms.

• Connect the speaker cables in such a way that they do not stick out

of the speaker terminals. The protection circuit may be activated if

the core wires touch the rear panel or if the + and – sides touch each

other (v “Protection circuit”).

• Never touch the speaker terminals while the power supply is

connected. Doing so could result in electric shock.

Protection circuit

If the core wires touch the rear panel and the screws etc., or the ±

sides touch each other, the protection circuit will be activated and

the power indicator will ﬂash red at intervals of 0.5 secs.

If the protection circuit is activated, the speaker output is isolated,

and the power supply goes to the standby state. If the power sup-

ply is turned off, after the power supply cord is withdrawn, please

conﬁrm that speaker cable and input cable are connected.

Also, if replaying large sound levels by using a speaker having an

impedance less than that speciﬁed (eg, 4 Ω/ohms), the temperature

will rise, and the protection circuit might be activated. The power

supply will go into the standby state, and the power indicator will

ﬂash red at 2 second intervals.

In this case, please switch off the power supply, and wait until

the AVR-1909 has cooled down, and the surrounding ventilation is

good.

Even if there are no problems with the surrounding ventilation and

connections, in the event of the protection circuit becoming acti-

vated, due to thinking that the AVR-1909 has failed, please contact

DENON Service center after switching off.
