hey i also had this problem, i don't know the name of these but they are basically plugs that you have to block output from the front rear and center speakers of the white/red cables... sry for bad description but its on the left side when looking at the back of the receiver, while all of the other speaker wires should be hooked up to the right with the twisting knobs... it took me forever to find this out but yeah it was a simple fix

SOURCE: can I conect harman Kardon avr 230 to apple tv

Yes, although it (AVR) does not support HDMI only component video.

Connect the audio to the receiver and the video directly to the TV if you have inadequate video inputs, or want to take advantage of the HDMI.

Does the Harmon kardan avr25 have an hdmi output


Nope. You get one component OUTPUT (monitor) and two component INPUTS (Vid 2/DVD) but no HDMI video output.

If you can input and switch HDMI video directly at your display from your cable/SAT etc. you should be fine, just run all the audio through the AVR-25 through the coaxial/optical digital inputs, L/R analog RCA or the 5.1 direct inputs.

Voice of both left and righ speaker is not equal


Can say I've seen this on a H/K. First swap the speakers left to right and right to left if the sound is low on the same speaker its the speaker not the receiver (could have a driver out). Could also be a dirty output relay.

Is the sound good other than it being low?
Is it that way with all inputs?

I have a hk25 II receiver. It is about 20 years old. It has been working fine but I had to relocate it and now the speakers sound is distant and the balance control does not work. I only have two speaker...


Hi Steve

I have worked on these units in the past as a Harman Kardon service agent. They are decent units and well worth persevering with.

By the sound of your symptoms, the signal is not making it from the pre amp stages to the power amp stages. This can be caused by a few different things.

1. check that the tape monitor switches have not been engaged
2. check to see that the pre out main in connections on the rear of the unit have been jumpered. See page 12 of the user manual for info about this.


You can also download a user manual for the amp from Kardon-AVR-25-II-Receivers-manual/id/390bh145/t/2/">here to assist you with working things out. I suspect that the jumpers are missing at this stage

I suspect that the jumpers on the rear are missing at this stage. Check for that and get back to me.

My receiver doesn't have a dedicated subwoofer output, can I still hook up a subwoofer? I have a harmon kardon avr 25


That would depend mostly on your subwoofer. There are some that slave off the front left and right speaker outputs and still pass the amp's power to the Front Speakers. That would be the only way that would ensure volume control.

Otherwise you have to feed a self-powered sub from the Tape Outs but that won't allow volume control from the H-K.
