Pop filter
Middle Atlantic Products
Booth SL1181
Split Screen Pop Filter: This pop filter uses two screens with a separation space that diffuses harsh consonants, which combined with the removal of the outer ring, provides an added measure of air dispersion. Sound is diffused by the first screen, dispersed by the open space between the two screens and diffused once again by the second screen. Any pops created by explosive consonants are eliminated before they reach the microphone. The Split Screen Pop Filter has also been engineered with no parallel surfaces between the two screens to avoid creating any resonant frequencies within the pop filter hoop.

25kW transmitter
Broadcast Electronics
Booth N1808
4MX 25: Based on patent-pending 4MX medium-wave digital transmission technology, which is a method of modulating the duty cycle of the radio frequency directly to produce a more linear output waveform, the 25kW transmitter is DRM-compatible and capable of linear audio reproduction.

Audio editing software
Adobe Systems
Booths SL3732, SL186-MR
Audition 2.0: In Adobe Audition 2.0, a new low-latency mixing engine with ASIO hardware support allows greater creative flexibility, with real-time effects and input monitoring. Automatic delay compensation keeps everything in sync while you mix an unlimited number of tracks, including as many as 80 simultaneous input and output devices. The revamped mixer panel lets users set up the routing, using inputs, outputs, sends and buses. Parameter automation can be recorded and adjusted in the mixer itself, or in the new automation lanes in the timeline. Users can also add 16 sends per channel, providing techniques for mixing and monitoring sessions. Use CPU power more efficiently by creating sends on several tracks that go to a bus with a reverb or other effects applied. Or use sends and buses to create mixes for specific purposes, such as a mix-minus feed for a remote session.
