Lebih Lengkap Mengenai PRECISION DELAY
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.
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.
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.
Features:
-Power Input:
Precision Delay comes with a standard IEC C14 power connector.
-Network:
Precision
Delay connects to a standard 100BASE-T network connection. This port is
used for Axia® Livewire, synchronization to a network time server, and
secure remote control via a web browser. If connected to the Internet,
it should be behind a hardware firewall.
-Analog Inputs and Outputs:
Stereo
inputs are electronically balanced XLR females, pin 2 hot, with a load
of 20kΩ: this makes it compatible with all modern
electronically-balanced outputs. If fed from a transformer-balanced
output, we recommend bridging a 680Ω resistor between pins 2 and 3.
Outputs are electronically balanced XLR males, pin 2 hot, designed to
feed a load of 600Ω or greater. Input and output sensitivity default
levels can be set from the front panel, and can range between +20dBu and
-10dBu.
-Digital Inputs and Outputs:
When set to AES/EBU via the configuration menu, this input conforms to IEC 958 Professional (5v
p-p,
110Ω balanced) on XLR connectors. When set to s/pdif, the voltage and
impedance switches to IEC 958 Consumer (.5v p-p, 75Ω unbalanced):
connect signal to pin 2 and shield to pins 1 and 3. Digital output
(selectable AES or s/pdif) is always active, regardless of whether you
are using analog or digital inputs. PD will lock to any valid 32 kHz,
44.1 kHz, or 48 kHz signal at the digital input connector, even if you
have selected analog for the input. In that case, the digital input
controls Precision Delay s internal sample rate. If Precision Delay is
not connected to a digital input, it uses its own high-reliability 44.1
kHz sample clock.
-Axia Livewire Inputs and Outputs:
Precision
Delay supports Livewire, with audio connections exclusively via the
network. Precision Delay also supports Livewire-based GPIO.
