Yamaha RX-V365 Receiver, Yamaha NS-AP2600S(BL) Speakers

Home-theatre receivers don't have microphone inputs. If you want to use the receiver as an amplifier in PA system, you need to use some kind of mic pre-amp or a mixer with mic inputs.
For PA mixer is needed anyway almost every time and all mixers have at least one mic input (with a pre-amp). Mixers have line-level output(s), which you can connect to the analog input of receiver.
Using receiver as an amp in PA has advantage that you have 5 channel amp. When using high sensitive PA speakers (as oposed to less sensitive Hi-fi home speakers), you can get good performance with the power rating of receiver. You could even use 2 separate channels for subwoofers and 2 channels for satelite speakers - but for that you would need a receiver with 5.1 analog inputs and special device called crossover which would divide the output from mixer into low-frequency signal and high-frequency signal which you would then connect to the front and rear analog inputs. But with RX-V365 you can use only 2 channels with analog input

With what signal did you try? Maybe your signal source (DVD/TV or radio) didn't contain any sounds for the center channel.
Go to the Setup menu, Speaker setup / Manual setup and find there item called "Test tone". It will output a test tone to each speaker individually (you will see on LCD which speaker is being tested at each moment). If you will hear a sound from the center now, there is no issue and center is working fine, just your source didn't contain any sound for the center.

If it doesn't work, then either you have faulty cable, faulty speaker or faulty center output of the receiver.
- Try connecting the center speaker to different output of receiver (this will test if speaker is OK).
- Try connecting working LEFT speaker to left output with CENTER cable (this will test if cable is OK).
- Try connecting working LEFT speaker with working cable to the CENTER output (this will test the output of receiver if OK - but use the Test Tone from Setup).

If you're expecting multichannel sound FROM THE TV instead of from the source you're watching, it's not gonna happen. TV's are notoriously poor sound sources. This one is no different.

Multichannel TV-related audio is best found at its source - cable / sat / dvd / bd....

I run video-related audio from my video sources directly to my TV and their audio directly to my receiver. Specialization yields best results.

I'd recommend skipping the Receiver for video, too, as it adds a lot of opportunity for HDMI-related incompatibilities and sound syncing problems. The more interconnects in the path, the more distorted it will become and the more opportunities for problems. Plus you can bypass the receiver and listen to lo-fi programming like news and weather through the TV's speakers if you like. Save a buck on electricity.

Just curious, which HDMI on the receiver is connected to your TV? Input or Output?

This note is on Page 11 of the manual:

Audio signals input at the HDMI jack are not output from any speaker terminals but output from the connected video monitor. To enjoy the sound from speakers connected to this unit,
-- make an analog or digital connection besides the HDMI connection (see page 13).
-- mute the volume on the connected video monitor

================
"Check SP cable." -- The unit is perceiving a short circuit. Are your speaker impedances sufficiently high? Disconnect the Front Right speaker and try raising the volume again. The speaker may be blown or the cable shorting.

Are you using it in full surround? Check all of your connections on the speakers,check the inputs and check your eq settings.

the RX-V365 cannot process the audio from the HDMI input. You will also need to connect a seperate audio input (either coaxial or optical) into the relevant input in the rear of the RX-V365

Are you sure the wire is not damaged somewhere? Are you sure that you are connecting the wire to the correct terminal on the receiver? Is the speaker OK?

To test all of this, try different combinations. With Right speaker working, disconnect the wire from speaker and connect it to the left speaker. If it doesn't work, then the left speaker is faulty.

Now disconnect the wire from receiver's right-front terminal and connect to left-front terminal. If it doesn't work, you are either connecting to wrong terminal or the terminal/receiver is faulty.

At last, try using the "left" wire to connect the rigth speaker to right terminal. If it doesn't work, the wire is faulty.

P.S. The +/- doesn't matter for testing, the sound should go either. It is just needed to have all speakers connected in the same polarity, because else the sound waves would eliminate themselves.

i have the same problem. any answers? [email protected]

This means wrongly connected speakers. Check the receiver without speakers to eliminate any failure. The error should go away.
Now carefully connect the speakers again, take care not to short-circuit the receiver. Also check the impedance settings on the receiver to match impedance of your speakers (either 6 or 8 ohms).

Hi Zanthena - my Yamaha rx v 2200 is doing exactly the same thing - did you manage to track the problem down? I have had my unit in for repair and the fault occurred again 6 hours after I re-installed it.

Any help would really be appreciated!
