Telos 25 Seven PD-A Precision Delay AES Digital Audio Broadcast HD Radio Blend [Refurbished]
( 234422380828) )
Tested/Guaranteed • Fully Working • PD-A Model • MINT- Cosmetic Condition • Web Interface • Up To 5 Hours Delay • Automated HD Blend Sync
An ex-demo unit that's in close to mint cosmetic condition. The item has been recertified by Telos to confirm that it works as it should.
This is a variable delay unit that applies an exact delay to program audio and associated meta data, and would most commonly be used in a HD Radio implementation to fine tune the analog FM signal delay so that HD/FM blend takes place seamlessly with no audible time shift between the signal paths. The unit can interwork with monitoring equipment to determine the optimum delay setting automatically. It has a total of five hours of solid state memory installed so it can also be used as a time-shift device for delaying an audio stream by up to five time zones.
For the avoidance of doubt, this is not a profanity delay - there is no dump button.

Saving Time, Managing Time
For nearly a decade, 25-Seven Systems has been helping you solve your station’s time management problems. Now we’ve got something for your toughest challenges. Precision Delay, our fourth specialized product, addresses applications such as drift between analog and HD Radio transmission signals and broadcast repeater synchronization.
Precision Delay offers sample-accurate delay times adjustable in fractions of a second; seamless watermark-protecting builds and exits; synchronized data streams; network accessible control; and 25-Seven quality and support.
Keeping HD Radio in Sync with Analog
With more and more vehicles equipped with HD Radio receivers, stations can’t afford confusing listener experiences due to blending out-of-sync analog and HD Radio signals.
Precision Delay lets you precisely set offset measurements by querying and retrieving them over IP from your BELAR FMHD1 or AUDEMAT Golden Eagle modulation monitor.
Take Precision Delay Out to the Ballgame
When sports fans listen to radio play-by-play at the stadium, they may not know if they are in the right ballpark when HD Radio diversity delay is running. Getting your station into “ball-game mode" means switching the HD Radio signal on and off without annoying listeners or impacting ratings. Precision Delay lets you smoothly build in and out of delay.
Protecting the integrity of ratings watermark codes during delay builds and exits presents special challenges. Precision Delay’s unique Watermark Safe Mode helps accommodate the time-based structure of watermark encoding. Our algorithms never alter pitch, so unlike other time manipulation processes, they never undermine the critical frequencies upon which watermarking depends.
Small Delays: Keep Boosters In Sync
Proper time alignment is critical to keeping main signals in sync with boosters or other transmitters relaying on the same frequency. Precision Delay lets you adjust delays by increments as small as a single sample.
Large Delays: Shift Across Time Zones
For facilities that need to delay content by several minutes to as much as four hours, Precision Delay provides a flexible solution with no spinning hard drives and no complicated programming. With “set and run" simplicity and solid-state reliability.
Delay Data & GPIO
Precision delay supports up to 3 independent data delays. Serial data over IP or RS-232 such as “now playing" metadata can be delayed in sync with audio — even when delay time is in transition. Contact closures can also be delayed on input so that they trigger against the appropriate audio on output.
AES Digital and Balanced Analog Audio
AES digital and balanced analog audio are standard.
Control Precision Delay from Anywhere
In addition to controlling Precision Delay using GPIO (contract closures), Precision Delay offers complete configuration and control over a LAN or WAN using a common web browser. Navigating though parameters is a breeze with our internal password-protected web server. The server gives you five separate pages for complete and convenient control over your PD. The network interface also lets you remotely install software updates. Whether your unit is located in your main equipment room or at the transmitter, control is probably right where you’re sitting now.
An Adobe Flash-based application replicates PD’s front panel on your web browser, so every button and display is present and functions just like the real front panel. Through careful client-server communications management, round-trip latency is almost imperceptible, creating a seamless user experience. You can even control PD from multiple computers. Just open a web browser interface on each, and anything you do on one computer will be reflected on the others, as well as on PD’s physical front panel.
Tired of learning hieroglyphics just to configure a delay? Navigating though “set and forget" parameters is a breeze with the PD’s Configuration page. You’ll find obvious control with all your settings on one simple screen, so you don’t waste time entering data though an ill-suited LCD interface.
