25-Seven Audio Time Manager


ATM allows users to delay the start of live programs and shorten their duration, in real-time, to accommodate the unexpected or create additional availabilities on an on-going basis. Its time compression technology is clean so that users can conservatively add about three minutes per hour to a schedule. Depending on the program source, users can more than double that and still maintain acceptable broadcast spoken language quality. The scheduler does not remove important content, change pitch, damage inflection or create artifacts. It integrates into digital and analog radio facilities providing smooth content insertions, network rejoins and broadcast delays.

Pyramid Speaker

Booth N1300

The design philosophy behind this speaker was to replicate modern boombox sound, which is created by being housed in plastic. The Pyramids use similar materials to copy this sound so that the engineer has a reference point for what the audience is hearing on its low quality audio products. Features of this speaker include 5 to 30W power rating; 8 ohms impedance; 80Hz to 18kHz frequency response; and banana-style inputs. The speakers dimensions are 7.12"H x 7.87"W x 6.5"D and it weighs 2.8lbs.

As with most Gepco products, this audio cable is UL listed CMR for permanent installation in a wide variety of locations.

KLZ Innovations Wire Relay

Booth N724

An IP-based content distribution system, Wire Relay enables multisite NewsRoom4 users to create their own news network, keeping affiliates supplied with current, targeted material. Stories received by a hub site are automatically pushed out to wire stores at locations across the system. Any embedded audio travels with the text, creating a local copy with ActiveX control at the destination. Configuration options allow the hub to determine which stories are forwarded, and to where.

Total Training Adobe Auditiontraining

Booth SL5526

Adobe Audition handle digital audio editing tasks within a single application. With multitracking capability to record, mix, and edit sessions with up to 128 stereo tracks, this audio program puts the power of a full recording studio in your hands. Total Training has developed a video training title, Total Training Presents: The Essentials of Adobe Audition. In close to four hours of instruction on two DVDs, Adobe audio evangelist Jason Levine walks through the full scope of Audition�s audio capabilities, from quickly constructing soundtracks with convenient looping tools, to creating effects, to using the program�s mastering tools to finalize audio mixes.

Musicam USA Roadstar

Booth N1006

Based on the NetStar IP and ISDN digital audio codec, this product is housed in a compact, portable enclosure with protective elements for controls, cables and connectors.

Did you know...?

How Well do You Know Las Vegas?

Let's see how you did.

The Nevada state tax on gambling revenues is 6.25 percent (this is what the casinos pay).

The MGM Grand is the nation's largest hotel with more than 5,000 rooms. The Western wing of the MGM Grand is actually the old Marina Hotel and Casino. It was renovated and connected with the new building instead of being razed.

The vacant lot across from the Sahara has been empty since the original El Rancho Vegas burned down on that site 40 years ago. The original El Rancho was one of the first resorts on the strip. Later, another hotel and casino called the El Rancho was built farther South on the Strip.

Steve Wynn's first Las Vegas investment was a large parking lot next to Caesars Palace. When he announced plans to build a hotel on the lot, Caesars Palace became nervous and paid Wynn a premium for the property.
