When it comes to big gigs it doesn't get any bigger than Madonna live in concert, which is why Sergio Carlo from 91.3fm in Santo Domingo travelled to Miami recently for her tour. 91.3fm ran a Madonna concert promotion, where they gave away tickets to the concert to competition winners.

Sergio is the co-owner and co-host of ‘12y2', a radio show on 91.3fm, and he broadcasted live for a full week from a variety of locations throughout Miami prior to the concerts. "I packed my trusted and well-used Tieline i-Mix G3 into my carry-on luggage and set off to Miami, along with the winners of competitions we ran to secure tickets to her concerts," Sergio said.

"In the Dominican Republic HSDPA and 2G cellular networks are available and I use the HSDPA network," he said. "In Miami I used the local Sprint EVDO Rev A network, so that I could broadcast affordably over the local wireless 3G cell-phone networks."

All Tieline codecs are capable of connecting over 3G, IP, POTS, ISDN, X.21 and GSM networks using interchangeable plug-in modules tailored to each connection transport. This means you can continue to connect to traditional networks and infrastructure and transition into newer technologies such as IP and 3GIP as required.

"We broadcasted for two and a half hours a day live from a wide range of different locations including malls and bars and all of our shows were fully sponsored for the entire week," he said. "Selling advertising can be difficult if the broadcast quality is poor, but it was very easy because of the i-Mix G3's high quality FM sound."

"The flexibility of the i-Mix was great," he said. "We used wired IP connections to broadcast on three days, wireless 3G on two days and we even used POTS on one occasion."

"When I connected over IP and 3GIP I used the Tieline Music algorithm to connect at 64kbps and send high quality mono FM audio back to the studio," he said. "I programmed the codec to connect using the ‘least delay' setting and the automated IP network management in the codec reduced delay to a point where it was barely noticeable."

"I checked on the availability of wired IP connections at the different locations before I arrived on-site," Sergio said. "When it was available, wired IP was easy to use. I simply plugged the connection into the LAN port on my codec and a DHCP IP address was automatically assigned. I dialed the IP address of the Tieline Commander rack-mount codec in Santo Domingo and connected very easily."

"On the two days that I broadcasted using 3G the codec connection was also very reliable," he said. "It is certainly great to be able to take the codec anywhere and dial over 3G to connect and broadcast wirelessly."

"On the last day I had planned to use a wired IP connection but two other networks were at the mall at the same time and they were planning to broadcast over the same connection," he said. "I was a bit concerned about the available bandwidth so I decided to use POTS because a phone line was available. The POTS line connected directly into the on-board connection on the codec and it worked really well."

"The ability of the i-Mix to connect over IP, 3G and POTS enabled me to connect using the most suitable network available, depending on the broadcast location," he said. "This is one of Tieline's major advantages."

"The shows were a lot of fun and we interviewed several famous people from Latin America. The show also included talkback callers who rang the show from the Dominican Republic," he said. "The number that the callers dialed in Santo Domingo was forwarded to a cell phone in Miami that I connected to the auxiliary input and output of the i-Mix codec."

"This allowed us to broadcast the show in our regular format from another country," Sergio said. "In fact some the callers didn't believe that we were in Miami and said that the sound was so clear it sounded like we were broadcasting locally!"

"It was great broadcasting with the Tieline i-Mix and everything went really well during the entire week," he said. "As I was the announcer and codec operator for the broadcasts it was also great to not worry about the codec and know it was reliable."

"I am working on a couple of new program ideas in the next few months and the Tieline is central in my planning," he said. "The Tieline codec is very commercial and just about any program idea you come up with, the i-Mix lets you do it..."
