Modem-Linksys Router and Spare Linksys Hub

Here is a photo of equipment placed on-top of the rack. I ran the network here for several years using the small Linksys Hub with little downtime. Although, I have replaced this HUB with a switch, I am keeping it available in case the Cisco-Linksys Switch takes a hit by a power surge (Lightning). And yes, lightning has damaged equipment here previously. I have lost two routers, two UPS units, and a computer power supply.

POWER AND NETWORK SWITCHING EQUIPMENT

+ AUDIO PROCESSING USED FOR WYLC-B STREAM

Equipment currently being utilized (pictured above) illustrates a Furman Power Transient/Conditioner located at upper portion of this photo. This power conditioner is connected to a 115-120 VAC power disconnect box which is wired into the main breaker box. The purpose of this equipment is to smooth out potential power sags-transients, and furthermore, condition the 60 cycle sine wave before it is routed to the 3 APC Uninterruptable Power Supplies which are in the bottom of the metal cabinet. Since all of the equipment here uses digital logic (CMOS) including Gates and Microprocessors, consequently, more than adequate grounding is necessary for maximum protection against emitted static discharges on days when the humidity is low, and especially during electrical storms.

The other piece of equipment is a Gorman Redleich EAS-ENCODER/DECODER. Although, the Federal Communications Commission has phased out requirements for the EBS system, tones are still sent by many broadcast stations accompanied by appropriate E.A.S. tones. Since we are no longer on the air this unit remains in the rack not connected, however, could be used to send audible alerts to the local listening audience over the internet.

The two small metal enclosures are used for matching unbalanced outputs from the computer used for storage of music files. Furthermore, since the Crate Audio Processor is considered broadcast/professional type of audio equipment, thus, the un-balanced output of the computer supplying audio must be converted to a balanced audio prior to being input into the Crate audio processor. Then, the output of the processor must then be converted back to an un-balanced audio signal prior to being input into the HP 531W computer which is used for our Vintage stream. Remember we are stereo now at 48Kbps, therefore, one converter box must be used for each channel, and furthermore, must be aligned the same for equal stereo reproduction.  An important question: Why does the Classic Country Stream Sound louder and better than the Vintage Stream given both is using the same band-width? Answer: Although the Crate Processor is better than the one used for the Classic Country Stream; remember a transformation process has occurred twice. (Unbalanced –to-Balance) then (Balanced –to-Unbalanced). Furthermore, the computer used for the Class Country Stream is using a SoundTek audio card and drivers, whereas, the Vintage computer is utilizing Legacy audio drivers. I am not sure if age would matter, however, the computer used for the vintage stream is nearly 9 years old.

Located below the two small metal enclosures is a Linksys 24 Port Switch which enables connectivity of the 5 computers currently being used, in addition to, the VoIP Converter Box for the Telephone.

2-APC 1300 UPS UNITS
BACKUPACPOWER.jpg

Above is a photo showing the lower portion of the rack. The two UPS units stacked on the right side provides back-up power for the Network Modem, Linksys Router, Linksys-Cisco Switch, and Telephone VoIP. So, if we have a power failure, at least I can use the phone for up-to 2 hours. Whereas, the other UPS can power the DT-220 MT computer, CD machine, and audio compressor/limiter for nearly 45 minutes.
The Vintage Rock website is ran from a computer connected to an APC RS 900 UPS, and therefore, enables the computer and HD to run for several minutes after a power failure.
