I had a chance to evaluate a new Panasonic TH-42PF20U recently. First impression: This seems to be a very well built display. For starters, there are 2 loop handles bolted to the display at the top edges on the back. This makes it easy to move the display around and can easily be taken off if desired as well. Although they donít add to the depth of the display, they can be seen from any angle of the sides. The bezel on this unit is fairly slim, all connections are vertical, and there are 3 cooling fans on the back top. The cooling fans go to full speed for 1-2 seconds when 1st turned on, they can be quite loud at full speed. But even after a few hours of testing and many full screen white fields, the fans never went to full speed during use. At their low settings, they were very quiet (not noticeable at all beyond 2 meters, even in a quiet room). There are small speaker terminals at the outer edge, on each side. This makes for short jumpers to connect to the optional speakers. I hooked up some bookshelf speakers for testing. The display is rated at 8 watts per channel and it sounds solid. Certainly not going to be jamming out but it has decent power to fill a room, much like an ABUS system. Mounting: The mounting pattern on the back is 600mm x 400mm. Most any universal mount should work fine. The holes come with plastic plugs in them, to protect the threads. The holes are slightly recessed but only by about 1/8Ē. I didnít use spacers and had no problem, the back is sturdy. Weight is given at 53 lbs. The handles on back made it easy to move these 53 lbs. around with ease.

I am looking for a better non-contact thermometer to measure mostly heatsink temps at a distance of no more than 10 feet. Looking at the Raytek RAYMT6 or Fluke 62 Tell me if you own a good one or bad.

Sony XDR-F1HD This new AM/FM tuner by Sony also does HD Radio and supports RBDS text info for analog stations. It has a retail price of $99. Don’t worry about dealer cost, there’s hardly any markup in this unit what-so-ever. It is fairly compact, measuring in at only 7 1/8” wide (this counts the chrome trim that sticks out 1/32” on each side – the body is only 7 1/16” wide), 2 3/8” tall, and about 6 3/8” deep (this counts the chrome trim sticking out on the front by 1/16” – it does not count the connectors in back). The unit itself is made entirely of plastic; even the connection panel in back is plastic. This leaves very little in the way of shielding from RF interference. The tuners themselves are encased in their own little metal box inside but the rest of the boards are still unprotected. The only other shielding appears to be a board mounted above the main board with circuit foil on it (green as seen in the product photos I took). The UL listing indicates 13 watts of power draw. Because of the digital nature of this device, it draws the full 13 watts all the time when on. So for 13 watts, it creates a lot of heat; plastic becomes very warm to the touch but not to the level of a cable box or satellite box.

I needed a wireless audio solution for a surround sound system, that I could not get wires to the rear speakers. I went with the Phonic WMSYS4 system (614-865MHz), thinking since it was a semi-pro solution and more expensive than the crappy cheap solutions commonly found, that it might work OK. The Phonic wireless transmitter was installed in a cabinet next to a Denon receiver, 1 wooden door between it and the Phonic wireless receivers located just 19 feet away at the back of the room. AudioSource monoblock amps driving Wharfedale Diamond 9.1 bookshelf speakers. 1ft balanced cable from Phonic wireless receiver to AudioSource amp. 1st: The build quality of these thin plastic boxes does NOT impress me, feels very cheap. The switches on the units are equally as cheap feeling. 2nd: The first system I got had a defective unit. Had to RA another one. The second system I got worked. 3rd: The sound quality was not very good for the price (not any better than the cheap Terk, etc... units out there). 4th: After a few days, the customer complained of hearing noise from rear speakers every now & then (main system was off). I switched from a low channel to a high channel to get away from that frequency. 5th: After a few months, the customer is now complaining of a noise that has started coming from the rear speakers (rather loud) all the time. Had the customer turn down the AudioSource amps till I get out and pull this wireless POS.
