Out-of-pocket for receivers and transmitters was about $3500. I don't know how many shows per week your theatre are running, or how long you expect the systems to last. But, you don't need top-of-the-line equipment to get 8 channels working together well. If money is a problem...

If money is a problem... They run 7+ shows per week. The theatre is in it's 29th year, so I would expect that they would be making a product-lifetime purchase. The Audio Technica 5000 series would be a similar price to Shure, when rebate is taken into account. When working with Squonk Opera, we purchased 6 used AT-5000 series for $500 per channel, without mics. I liked the Audio Technica, except for the body pack mic connectors. AT has a collar that slides too easily to disconnect. It is easy to accidentally unplug a mic during a costume change. One thing I do like about Audio Technica is the screw-in antennas. An antenna can be replaced easily, if damaged. But this ease of replacement makes the susceptible to being unscrewed accidentally. I made sure to check them every day. The theater's lavalier mics already have Shure connectors. They could purchase adapters, but that would be another failure point to be concerned with. The Shure UR1 can transmit at 50mW, or even 100mW. The lower level Shure & AT can only transmit 30-35mW. - Denny

The good news is that many say that another frequency reassignment like we just experienced might take another 20 years to come together. > The Audio Technica 5000 series would be a similar price > to Shure, when rebate is taken into account.

We obtained the 2 ATs so that we could share the receiver between headset and handheld mics. I subsequently found out about the Rat Sound Audix adaptors for Shure handheld wireless bodies. > One thing I do like about Audio Technica is the screw-in > antennas.

Our wireless mic stable is almost entirely composed of Countryman E6s, which can be converted without adding more parts or connectors to the system. > The Shure UR1 can transmit at 50mW, or even 100mW. The > lower level Shure & AT can only transmit 30-35mW. Based on my experience with Wifi gear that runs at higher power levels than standard, 5 dB more power can be a signficiant advantage.

It was all scheduled to happen here until someone let the authorities know that the 2012 olympics could not go ahead as such things as walkie-talkies etc wouldn't be available for use. All of a sudden everything is on hold until after 2012. Phildo |
