Question about NAD C340 Integrated Amplifier

Amplifier cutting out when volume is increased

My amplifier cuts out as soon as I exceed a fifth of the maximum dial turn on the volume dial. All of the LEDs start to flash and I can only get the amplifier to work again by switching the amplifier on and off again and reducing the volume. Any suggestions gratefully recieved.

    I have a pyle 1800 watt chopper series and a 600 watt boss amplifier and they both cut on and off when i turn up the volume about a 4th or a 5th of the way up. The protection light doesn't come on.. the power light just slowly disappears and the amplifer just cuts off...

My hometheater onkyo ht-s 3500 problem increCVasing volume level 45 cut off amplifier


Hello KAMAL, This means that the unit is going into protect mode. This is typically caused by something internal or a speaker connection could be causing it. To isolate if it is a speaker or the receiver you would first have to turn it off and disconnect all of the speakers. Turn the unit back on and turn the volume up to 45 with no speakers connected. If the unit stays on then you will know that one of the speakers was causing this short to happen. If that is the case I would check all of your connections. If the unit turns off when the receiver has no speakers connected then it is an internal issue and it would have to go for service. Thanks, FJD

I bought 2 lanzar sub 6000w and I have a monoblock lanzar dct5001d when I open high volume the power indicator blink and cut when I turn down the volume it play oky


You may have to increase the size of you power cables to the amplifier. Both the POSITIVE and NAGATIVE wires should run directly to the battery. At this power level, you may actually want to install a battery right at the amplifier, and use the shortest possible cables between the battery and the amplifier. connect the battery Negative and positive terminals directly to your car battery using #6 cable as a minimum size. This will almost guarantee enough power for your ampl,ifier to run properly.

Everytime i try to play my system at full volume it cuts out then keeps playing and carries on doing this to i turn it to a certain volume


First of all find out the recommended speaker impedance for the receiver. Then find out the impedance of the speakers you are using along with it.
Simple rule is the speaker impedance can be higher but not lower than the recommended value. If it is so the receiver will run hot and if you turn up the volume higher it will run even hotter and then the protection circuit will cut off the Amplifier output to prevent burn out of components. Even if you have one defective speaker this cut off can happen. To confirm defective speaker -- disconnect one speaker at a time and turn on the amplifier and play it at cut off volumes.If by disconnecting one particular speaker the Amplifier does not cut off -- THAT SPEAKER HAS A SHORTED COIL and needs replacement.

Everytime i turn my gain up my amp cuts in and out an the only way to keep constant bass is if i keep the gain on one


When you turn the gain up you are probably exceeding the maximum input for the amplifier.
Try adjusting it on the amplifier itself rather than from the head unit.

Disconection the sound


This will be a protection feature of the head unit. If you are not using an amplifier, when the power required by the speakers exceeds the power output of the head unit, it will cut out until the volume level is reduced.

If the head unit turns completely off, you may consider adding an amplifier to the sound system.

Sound cuts when volume is turned up


check that power amplifier rating(how many watt)must be more than total speaker rating by 20% at least..
exampel:if speakers watts are 100 watt-amplifier watt must be 120 watt.

Interior speakers cut out when the volume is turned up


You may have speakers of an incorrect impedance attached to the unit since the problem occurs when audio signal level is increased and the current goes up.The unit is shutting down to prevent damage. I would check the speaker connections and make sure that the speakers impedance are matched for the unit you are using.
