No hd reception in polk audio isonic - Polk Audio I-Sonic System

Posted by on

  • Scott Rochette Dec 03, 2012

    I've used my Polk Audio I-Sonic for about four years without incident. Lately, however, it cannot latch onto an FM-HD signal. It's connected to a rooftop antenna and has no problem receiving relatively distant stations, but the HD indicator blinks incessantly without locking onto the HD signal. My other HD radio has no problems getting a HD signal with an indoor antenna, so I know that I am capable of getting them. In addition, the radio continues to play when the unit is set to Aux, so I'm guessing that there are larger issues with the unit. This is sad, because it is a great sounding unit, with no other companies offering table radios with the features this has.

Order a Re-Cone kit from Polk, or have a local company re-cone it. It can be a little tricky if you haven't done a recone before.

Setting up a Yamaha RX-V690 home theater system

you almost have the exact same situation i am in. i have the same receiver, and going to purchase a panasonic 50" (th50px75u). i think what i will be doing is running a hdmi from my hd cable box to my tv, and installing an audio cable (red/white) from my tv to the receiver. i believe there is an audio input below the hdmi insert. i have polk audio, but theyare about 10 years old, they sound great, but just too large....and may be purchasing a harman kardon system. which models do you have from polk? i have the rt16's, cs350ls center, and fx/500 rears. let me know what you have come up with as it has been a while since you posted this.
