AVR-3300 No sound with any source but power amplifier is good,all of sound pre out were be muted . Every power supply are good and display panel is good. Help me to solve it. Can connect with me or reply at : thanh_dinhnguyen @yahoo.com

To add a 2-channel amplifier to your Denon AVR 2307ci receiver, you can follow these general steps:
1. Determine the amplifier connection type: Check the specifications of your 2-channel amplifier and identify the available input and output options. Common connection types include RCA (analog) and speaker wire (for binding posts or terminals).
2. Identify the pre-out connections on your Denon AVR: Locate the pre-out connections on the back of your Denon AVR 2307ci receiver. These are typically labeled as "Pre Out" or "Preamp Out" and may be color-coded. You will need to find the pre-out connections for the front left and right channels.
3. Connect the RCA cables: If your amplifier has RCA inputs, use RCA cables to connect the pre-out connections of the Denon AVR to the corresponding inputs on the amplifier. Connect the left channel pre-out on the Denon to the left channel input on the amplifier, and do the same for the right channel.
4. Connect the speaker wires: If your amplifier uses speaker wire connections, connect the front left and right speaker outputs of the Denon AVR to the corresponding inputs on the amplifier using speaker wire. Make sure to observe the proper polarity (positive and negative) when connecting the wires.
5. Configure the Denon AVR settings: Access the setup menu of the Denon AVR by using the remote control or the front panel display. Navigate to the audio settings or speaker configuration section. Look for an option to enable "Preamp Mode" or "Preamp Outputs." Enable this option to ensure that the front left and right channels are redirected to the pre-out connections.
6. Set the amplifier to the correct input: If your amplifier has multiple inputs, select the input that corresponds to the connection from the Denon AVR.
7. Adjust volume and settings: After completing the connections, you may need to adjust the volume levels on both the Denon AVR and the amplifier. Use the Denon AVR as the primary volume control and adjust the amplifier's volume accordingly.
It's important to consult the user manuals for both your Denon AVR 2307ci and the 2-channel amplifier to ensure proper setup and compatibility. If you're uncertain about any specific steps or settings, it's advisable to consult the manuals or reach out to Denon customer support for assistance.

Hi, you can have a fault in the mute circuit of the amplifiers, control the mute voltages in the dee circuit Display

Hola, puedes tener una falla en el circuito de mute de los amplificadores, controla las tensiones de mute en el circuito dee Display

Yes. Your receiver has the required pre-out connection terminals needed to go to an external amplifier. That would make your receiver operate as the pre-amp/processor.

First verify that the mute is disengaged (toggle the mute button). Second, check the sound configuration to make sure the internal speakers are on, or check the sound output to make sure it is going to the inputs of an external audio amplifier (stereo receiver) and that the external amplifier is working. Try a different input source - perhaps the problem is your cable feed or DVD player.
If the internal speakers are on, the volume is up, and you still don't get any sound from a known-good source (TV channel, DVD player, etc.), then try running the sound to a stereo system as described above.
If that works, you may have a shorted speaker amplifier (depending on the set's design, this may blow a fuse supplying power to both left and right amplifiers or a speaker protection circuit will keep the speakers disconnected). These aren't usually hard to repair, but if you find a blown fuse, fix the amplifier before replacing the fuse or you'll just waste another fuse.

The manual is at Bose.com.

In any question regarding connections the exact models of all parts in the scenario should be defined.

"Pioneer amplifier" is not unique nor revealing. Integrated amplifer? Power amp? Tape Loops available? Pre-Outs? What's involved as a preamp?

The key thing to know is that any amplifier channels driving 901's must not drive other speakers as the Active EQ severely modifies the Line Level source input. If the EQ (or any sound processor) is used in a Tape Loop on a modern multichannel digital-audio-capable AVR, ONLY 2-channel analog sources will function when the Tape Loop is engaged; and all downstream speakers will be affected by the processing. That's par for the AVR course.

Bose 901 use in multichannel applications (which I have) will require access to Pre-Amp outputs for the chosen channels (likely the Front) and you will need to get a separate amp for the 901's, placing the EQ in series with the chosen amplifier. I currently drive mine with a Carver MT-200T.

audio ic problem or component around audio ic.. good luck

Does this help?

Just open the unit and then check the fuses,if the fuses ok. Then check the filter capacitor in power supply if its ok ,then check the regulator,if its ok. Then check the four transistors output stage of the amplifier. Maybe there is the problem there.

Good luck..

Dont forget to rate:

Hi...

I just opened up an AVR3300..It's trouble is that it goes into stndby
at once.
The BIG power supply caps are VERY swelled at the top.

That would be my informed view on why it's bad.

I suggest you look at that being your possible trouble too.

If "Digital" sign blink on front panel, it means DSP do no start properly. If DSP do not start, main UC mute audio. Change IC, AT49LV002-70TC (IC 817 ) at DSP board (Denon P/N: 262 3010 006).
