Re: Simple audio swithcer for two sources

I was about to make a suggestion but Kevin beat me to the gist of it. I have done this with a BT switcher and an old computer with a serial port or a serial to USB converter. That is likely your cheapest option as any hardware with a built-in GUI would probably not be inexpensive.

Re: Out of Control Audio

My question to you guys is, would you simply suggest they begin normalizing all new songs and try to work their way back through the existing library? Yes, but you and the staff need to note which songs are way too hot and make those a priority for normalization. ... is there a better technique to ...

Deep - Even though Fossil already got that info to the OP I would appreciate seeing your cheat sheet for future reference.

Walmart Drive-In Movies Using FM Transmitter

Walmart will begin showing drive-in movies in Walmart parking lots at 160 stores beginning on August 14. They apparently have six systems to do so as movies will be shown at only six locations nationwide each day. They will be using FM transmitters to convey the audio to viewers' cars. I have been u...

Re: Sony BVH-2000PS. Missing TBC Card

How long have you had the machine? Have the colors always flickered since you got it? It could simply be that it needs alignment. That is not a procedure that I would recommend for the inexperienced or those without proper instrumentation and tools. More than 20 years ago I was CE of a TV station wi...

I'll second that. If you buy a cheap transmitter you get a cheap transmitter - it isn't worth buying anything new that may give you frequent trouble.

Re: OMB Exciter EM 50

There are a number of medium power dummy loads available as pulls from cellular phone service. If you know any TV CEs in your area check with them. I was given a no longer needed reject load by a UHF CE after they converted to digital. It is a Bird 8201 Termaline, handling 500W from DC to 2.5 gHz. ...

Re: ADC Punch Block Tool

Just curious... What do you need a patch bay for? I am curious as well. I haven't done a new build with a patch bay in many years. The last analog cluster studio facility that I built, nearly twenty years ago, used a combination of Broadcast Tools switchers and a cross-point switcher, all under com...

Re: Commercially available replacement for the ATU-20 Coupler

Do you need one for carrier current or for antenna matching? The ATU series (ATU-20, -30, -60, -100) were designed for antenna matching, largely for TIS stations but also for commercial broadcast. The TCU-30 is a different beast, used for either carrier current or antenna matching. The TCU-30 is som...
