Studio Buildout, Part III

I have been so busy that I forgot to post the pictures of the completed studio build out.  Overall, I would say that I am pretty pleased with the end result.  Of course, this is not Manhattan but rather an unrated market in central New York, and the budget reflected that.  Overall, the radio stations are in much better technical condition than before.  They are now located in the center of their community within walking distance of the town hall, other civic locations and activities.

There are five radio stations broadcasting from this new studio space.  Two stations are simulcast using the Westwood One Classic hits format from the satellite.  The only AM station is a Fox Sports Radio affiliate from the satellite with a local morning show.  Another one is a “we play anything” computer juke box and final station has a country format with quite a bit of local content.  Any station can go on the air from either studio.  In addition, all stations can simulcast the mother ship from Oneonta, which comes down via a Barix Exstreamer 1000.

Walton TOC

The Technical Operation Center consists of four racks containing the Ethernet routers, switches, a patch panel, automation systems, audio routing switchers, air monitor receivers, audio distribution amps, Barix units, Wheatstone Blade IP 88A STL, etc.  The equipment racks came from a disused site in New Jersey.

The satellite dish and receivers are located at the transmitter site, audio and closures come back via the Wheatstone Blade IP 88A.

Everything in this room is backed up by a STACO 2.5 KVA UPS.

TOC wire terminations

The wire termination from the studio are mounted to Krone LSA-PLUS blocks.  Studio trunk wiring consists of connectorized 25 pair CAT 5 cable.  There are also six runs of shielded CAT 5e cable for Ethernet and extended KVM from the TOC.

There is a manual transfer switch with a NEMA L14-30 input receptacle on the bottom.  A twenty for 10/4 SOJ cable will reach the ground from the window in the left hand side of the picture.  This is the standard NEMA plug/receptacle set for a moderate sized portable generator.  That feeds a 100 Amp sub panel which in turn feeds the racks and studio equipment.  Thus the entire facility can be run on a 5000 watt (good quality) portable generator in the event of a prolonged power outage.

The ground buss bar is connected to the main building ground at the service entrance.  All racks and studio consoles are grounded to this main ground point.

The air monitor receivers feed both studios.  There is also a provision to connect audio silence sensors up to each air monitor DA to notify the station staff in the event of an off air situation.  Believe it or not, this type of system has never been installed for these stations.

Studio A is the main studio.  The AudioArts Air4 console is a good fit for this type of operation.  These consoles have USB outputs, so the console can act as a sound card for the digital editing computer.  Each studio is equipped with an air monitor switch that can select any station to feed the external monitor input on the Air 4 console.  This allows the guy on duty to keep an eye on all the signals coming from the facility.

Studio A

The counter tops were custom made at a local kitchen place on trade. The microphone are Heil PR-22 with shock mounts, which are better than the Realistic mics in the old studio.  This is the first time that the main studio has had more than one microphone. The morning show guy has already pressed those guest mics into service with a few on air interviews.

The monitor speakers are JBL LSR305 mounted on home made speaker stands consisting of 18 inch black iron pipe and floor flanges.

Studio A

The small equipment rack is on casters and can roll out from under the studio furniture to get at the back of the equipment.  A used Gentner DH3 TELCO hybrid is used to get phone callers on the air.  Adobe Audition is used for editing and production on the left hand computer monitor.  That CPU is in the bottom of the roll around rack.

Studio A

The office chair and other furniture was also acquired on trade.

Studio A

What the operator sees. STORQ computer on the left for music, Scotts SS32 on the right for automation. Both are extended from the TOC. Unless the morning show guy is live on the air, the console is bypassed and the audio stays in the TOC.

It all works pretty well.

Studio B

Studio B is the same as Studio A except fewer microphones.

Again, this is not a Fancy Nancy installation, but it does get the job done.

Studio Buildout, Part II

Some pictures of the studio build out in progress.

This is the counter top, mounted on a riser with the wire way cut into it. These counter tops will have AudioArts Air4 consoles installed on them.

Studio is taking shape. Console mounted with microphones. The rack mounted equipment goes in the Middle Atlantic rack under the counter top to the left of the console.  That rack is on casters so it rolls out to get access to the back of the equipment.  We have pretty much done away with cart pods or other counter top equipment housings.  The automation and other computers will be mounted in the rack room and extended to the studio with IP KVM extenders.

Sub Panel with manual transfer switch
Sub Panel with manual transfer switch

We installed a small Square D sub panel and manual transfer switch. This is to prevent the “Space Heater” outages, you know, when the morning show guy plugs a space heater into the same circuit as the console or computer, trips the breaker, then calls you because they are off the air. Yeah, good times.

In addition, the manual transfer switch will allow them to use a good portable generator if there is a prolonged power outage. On the bottom of the switch I installed a 30 amp twist lock input receptacle.

Since the building is older, the grounding buss was installed and wired directly to the ground at the service entrance panel.   The building sub panel for this floor is using conduit for the ground conductor back to the service entrance panel, which used to be code compliant but no longer.

STL/LAN extension dish installed on roof top. I used an old non-penetrating roof mount for a four foot satellite dish.  The building owner was very specific about not having anything puncture the new rubber membrane roof.  Thus, the heavy rubber mats and sand bags instead of cinder blocks.  These stations will be using a Cambium PTP-250 system for STL/TSL and LAN extension. This will haul program audio for five radio stations plus satellite backhaul and remote control. It is a relatively short path with the FM tower visible from the roof top.

It was kind of hazy when I took this picture, but if you look really close, you can see the FM tower out there on the hill top.  The path is 3.37 miles (5.43 KM).  With a 40 MHz channel width, that should net about 175 Mbps bi-directionally, which is more than enough to do what we want.  This set up will require a pair of managed switches and some VLAN configuration, which I will post separately.

Studio Buildout, Part I

We are in the process of building a couple of new studios for one of our clients. This one involves a small market combo of one AM and four FM stations.  These stations were formerly located at one of the transmitter sites, two miles outside of town on top of a large hill.  That site could be difficult to get to during the winter and the building itself was not in the best of shape.  Thus, plans were made to move the studios to a better location.  Fortunately, we discovered that right in the village there are several suitable office buildings.

Any worthwhile project needs to be planned for.  The first consideration is the Studio to Transmitter Link (STL) paths.  Since this is a radio studio, it makes sense to located it where viable RF STL paths exist.  One might be surprised by the number times the issue of bad or non-existent RF STL paths has come up during these types of projects.

The next thing to check is the satellite path.  The plan right now is to keep the satellite dishes at the transmitter site, however, at some point in the future we can relocated the satellite dish to the roof of the studio building if desired.

The floor space was measured out and I drew out a floor plan:

Before we started work, all of the walls were painted and new carpeting installed.

Almost nothing at the old studio is worth keeping. Thus, all of the furniture, consoles, racks, STLs, and other equipment needed to be ordered.  A local kitchen company traded out the counter tops, which we picked up at their facility and delivered to the studio ourselves.

We will build risers for these on site then mount the consoles and such.

In the mean time, most of the new studio equipment has been ordered and delivered. There are still some outstanding items that have not arrived, but I am assured that those are in process and should be showing up shortly.

These equipment racks came from another market, but are in good shape.

I had a good meeting with the building owner regarding roof access, a sub panel for the racks and studios and other issues.
