Currently, there are 2 AV Receivers available in the market, which is absolutely value for money and budget AV receiver. The first one is Denon AVR-X250BT and the other one is Denon AVR-X550BT. If we talk about the quality of sound? Then it is absolutely better AV receiver under 40000/- rupees. And the wattage of the Denon AVR-X250BT and Denon AVRX550BT is 130 watt RMS into 5 channels at 6 ohms. Hence, which is good enough to drive any wall-mountable or Qube speaker under 200 watt RMS.

These are high-quality discrete power amplifiers for powerful sound. Bluetooth wireless audio streaming is also fantastic. There are a few latest audio technology inbuilt like Dolby True HD and DTS-HD Master Audio decoders. 5 HDMI input to connect more HDMI input sources. W/HDCP2.2 and 3D/4K with ARC(Audio Return Channel) and CEC- HDMI 2.0a. There are 2 optical audio inputs whose connection led to two different audio sources. Where HDMI output is not available like some smart TV etc. These AV receivers are fully easy operation by quick select buttons, Dolby Vision, HLG, and front USB input. And a dedicated Bluetooth app for easy operation in Denon AVR-X550BT.

There are a few technical issues which are commonly found in the Best AV Receivers Denon AVR-X250BT and Denon AVR-X550BT that we will discuss here:-

Symptom:- The system is tripping. Went to standby mode within a few seconds. And a red LED light is flashing, the display is coming for a moment and it goes off. In another way, it’s going to protection mode.

Solution:- If the system is going to stand by mode within a few seconds. That means it’s going to thermal protection and there are a few reasons for thermal protection.
These Denon AVR-X250BT and Denon AVR-X550BT work with only 4 to 8 ohms impedance. Sometimes due to some technical issues, some speaker comes down below 4 ohms. Then the particular speaker consumes more current than the others and the maximum consuming current produces more heat because wasted power converts into the heat.

If the temperature got higher than the acceptable value then there is an activation of the thermal protection circuit. Therefore, this protects the Denon AV receiver from a further big problem. To rectify this problem you need to disconnect all the speakers from the AV receiver’s speaker terminal. And then check the AV receiver again. If the problem was in the speaker then your AV receiver will not go to tripping or thermal protection or in standby mode.

If the problem still persists that means the speaker is fine and the problem is in your Denon AV receiver, there are many reasons for tripping but we will discuss them here for maximum possibilities-
Most of the time we have seen that the output Darlington transistors are defective, most of the time it’s one channel defective and few other rare cases it happens due to 2/3/4 or more channels.

We have even noticed that some output Darlington transistors are perfect but due to driver section or pre-amplifier section transistors, Zener diode and 4148 rectifier diodes are defective. It is a very common problem and very easy to solve and not expensive. As a customer, it is very difficult for you to solve this but if you visit an authorised service centre, it is hardly matter to them.
