Digital on-air radio board
This console features a compact footprint and a built-in router that assigns any source to any input or monitor. The unit controls 16 input
channels and two caller phone channels. It is equipped with digital bar
graph metering and alpha source displays. This product provides analog
and digital stereo PGM and AUD, mono 1 and 2 output buses, in addition
to four mix-minus outputs. Assignable machine control ports are
optoisolated. Direct access to rear DB-25 I/O connectors facilitate
easy countertop installation.
Combiner and filter
The combiner and filter enables an FM station to implement HD Radio by combining the output power of a digital transmitter with an analog
FM transmitter for use with an existing antenna system. A
high-performance, dual-elliptic band-pass filter is included for
special filtering of the digital transmitter. This filter design has
exceptionally uniform response across the channel bandwidth for group
delay performance and negligible effect on the digital waveform. High
suppression of out-of-band energy ensures compliance with the spectrum
mask and digital occupied bandwidth requirements of the FCC.
Middle Atlantic Products
A series of riser bases, raised floor rise feet and support angles, these risers provide broadcast engineers with a time-saving and
effective means to install equipment rack enclosures and related cable
management in raised floor broadcast facilities. The riser bases can be
used as standalone units or in conjunction with the feet and angles to
meet a wide range of raised floor challenges. The RIB series riser
bases are designed to elevate equipment racks 2-½" above the floor
to provide a lower cable chase between rack enclosure systems in
multibay applications. The bases are also useful for performing field
rough-ins before rack enclosure systems arrive on site.
Besides all the features of the company's Digilink-Free, this version uses off-the-shelf PC sound cards. It can be used live on air
with a jingle array and six-cart stack or in full automation. The
built-in scheduler features a one-week rotating schedule. Manual or
timed audio recording can be built into a schedule. The system supports
two sound cards, allowing users to preview audio files during on-air
use. This also allows the system to operate on air while a schedule is
built from the same computer.
Audio acquisition tool
Dalet Digital Media
An audio acquisition tool, this product is designed to help editors and journalists enrich the Dalet database in a quick and easy way. With
plug and play, files from a Nagra digital recorder or tracks from a CD
can be easily ripped without thinking about file conversion. This unit
performs the following operations automatically: converts audio files
to a pre-selected format, copies in an automatic batch audio files to
Dalet central server from local storage (CD or Nagra via USB port),
incorporates metadata for easy retrieval and Nagra via USB connection.
This tool connects with the Nagra handheld audio recorder/player
ARES-P/RCX220 via a standard USB port. Once the device is plugged, the
journalist highlights the files to be transferred in the Trackfilerplus
window, and then clicks and the transfer begins. The transfer speed is
several times the real time. It works on any Dalet version.
Digital asset management
This audio trafficking system allows for: multilevel user access, superior quality MP2 and MP3 files, automated and on-demand spot
retrieval, traffic document attachment, instantaneous online delivery,
guaranteed next-day delivery offline, online access to pending
deliveries, current inventory and traffic instructions for any
authorized users on a network 24/7 technical support.
The Armstrong FMX-30B is the next generation in frequency-agile exciters. The transmitter offers low distortion and intermod values,
combined with a high signal-to-noise ratio. This
microprocessor-controlled unit features a front LCD screen, which
displays all system parameters on a scrolling menu including
modulation, power output, frequency and power supply parameters. Other
unique features include: front panel frequency agile, advance
microprocessor control system, built-in low pass filter and directional
coupler, LCD display of all system parameters, full remote control and
status indicators, alarms for over temperature, VSWR foldback and mute
and MPX and dual SCA inputs.
The Masterail system is available in a modular component console style and an Imagemaster workstation. All devices mount anywhere along
the rail and are completely independent of each other, as well as, the
rest of the structure. This feature allows both console types to be
completely reconfigured, repurposed and reused, quickly, easily and
inexpensively, now and anytime in the future. The system incorporates
current materials, precision laser-fabricated parts and third-party
RCA phono connectors
The RCA phono connectors feature isolated, recessed sockets in nickel or black chrome housing, and are available in D-series style for
use with universal mounting plugs. Either housing can be ordered in
black, red, yellow or white to enable color-coding. The new plugs,
which feature gold-plated contacts, can be ordered to match the colored
rings available on the company's NYS373 plugs. The RCA phono sockets
feature a high current and voltage rating. The shell and contacts are
brass with gold plating, and the D housing features nickel or black
LAN/IP audio distribution
One or more server PCs take multiple, live, audio sources and make them available across an existing network. Any PC on the network can
receive the audio feeds by running a small receiver module, which
emulates a tuner by selecting a channel. New sources and destinations
can be added by loading the appropriate software. Work with standard
Windows hardware and sound cards. The system uses multicast technology,
and installation tests have shown that 50 stereo audio channels at
broadcast quality occupy only six percent of a 100Mb/s network. Audio
can be broadcast as linear .WAV, MP3 or MP2 files. Users can purchase
the software only or MDO can supply configured servers.

Multistream audio adapter
The ASI6122 is aimed at high performance broadcast applications requiring MP3 record and play with analog and AES/EBU digital
interfaces. The adapter uses a 150MHz Texas Instruments TMS320C6711 DSP
and provides two stereo outputs, two stereo inputs, two record streams,
two play streams and a powerful multirate digital mixer. Audio format
choices include MP3, MPEG Layer 2 and linear PCM. This product features
four stereo playback streams and two stereo record streams. MRX
technology supports digital mixing of multiple stream formats and
sample rates. Two balanced analog and digital play outputs and 24-bit
analog-to-digital and digital-to-analog converters are available.
Soundguard transient voltage suppression protects against lightning and
other high voltage surges. There are as many as eight cards in one
system and 8M bytes DRAM allow for on-board buffering. Windows 95/95,
Windows NT, 2000, XP and Linux software drivers are available.
Clean Source UPS
An uninterruptible power supply, this system delivers the highest level of power availability, conditioning and harmonics cancellation
for sensitive digital broadcast systems. These power protection systems
protect networks, transmitters and microwave uplinks from the most
common power disturbances that can interrupt broadcasts. While
combining a rugged steel flywheel with solid-state power electronics,
this technology incorporates a flywheel motor-generator that stores
kinetic energy in its constantly spinning, quiet, low-friction steel
disc. Stored energy from the flywheel is instantly converted to
electricity that powers the critical load during short power
fluctuations. During prolonged power out-ages, the UPS seamlessly
transfers to a stand-by generator for continuous power.
