AmpliVox Wireless PA Supports many Media Devices
The updated SW720 Wireless PA system includes several practical accessories.
AmpliVox Sound Systems has unveiled its newly updated SW720 Wireless PA system, a versatile PA package that supports all types of external media. The SW720 PA enables audio or video to be played from MP3s, CDs, DVDs, or any iDevice from Apple (e.g., iPhones, iPads, or iPods), complemented by a wireless handheld mic for voice amplification. For audiences of up to 500 people and rooms as large as 2,500 ft2, the SW720 is an all-in-one solution for multimedia presentations.
The revamped SW720 Wireless PA system with a remote-controlled DVD player now includes AmpliVox’s S1732 cable and adapter, enabling iPads and other Apple devices to be simultaneously played and charged. The unit also contains an integrated DVD/CD/MP3 disc player with a USB/SD card reader and video output that enables DVDs to be viewed with a projector or other video display. For voice amplification, the SW720 features a built-in UHF selectable 16-channel wireless receiver with a 300’ range wireless handheld microphone.
The SW720’s straightforward controls customize presentations. A voice priority switch mutes music when the mic is in use, and separate bass/treble controls enable easy sound adjustments. Weighing 11.5 lb, the molded plastic enclosure is durable and portable. A protective cover offers many pockets for accessory storage. The SW720 can run for up to 6 h on its built-in rechargeable battery, or it can be powered with the included AC power cord.

Dayton Audio’s DVC Subwoofer
Dayton Audio’s DVC subwoofers are designed to improve power handling and reduce power compression.
Dayton Audio’s Ultimax Series DVC subwoofers are purpose-built to move air and create clean, articulate, and fast bass. To improve power handling, increase thermal management, and reduce power compression, Dayton Audio designed the Ultimax Series with large black anodized formers and vented pole pieces, under-spider ventilation, and two-layer copper voice coils.
The Ultimax’s “Tall-Boy” rubber surround is intended for extra-long linear excursion without reducing the Nomex honeycomb/woven glass-fiber laminated cone’s surface area. Copper shorting rings and a pole piece cap reduce inductance and distortion, while the Ultimax’s dual spiders maintain linearity at high drive levels.
Dayton Audio’s Ultimax Series dual voice coil subwoofers are engineered and built using the latest in subwoofer technology. They are now available in 10”, 12”, and 15” sizes. Dayton Audio products can be purchased in the US through Parts Express (www.parts-express.com).

DANLEY Improves SYNERGY HORNS SH Series
Danley raises the sound pressure level (SPL) on its Synergy Horns SH Series
Danley Sound Labs recently announced improvements to many of its already highly-regarded SH Series full-range loudspeakers. The new versions are identified by the suffix “HO,” which stands for “high output.” For example, if someone wants to get the most performance out of the Danley SH-96, order the Danley SH-96 HO.
The new designs use a more powerful two-way high frequency. As a result, the low- and mid-frequency drivers can be used to their full potential yet maintain Danley’s characteristic frequency response, phase response, and fidelity. In conjunction, the HO designs use a new crossover and have additional options for bi-amping and for changing the low-frequency impedance. Because the cabinets themselves haven’t changed, the new versions retain the coverage and frequency loss patterns of the originals. The new models include the SH-95 HO, the SH-96 HO, and the SH-64 HO.
Because the new switch panel cannot operate reliably if left exposed to the elements, weatherized versions of the new high-output loudspeakers must be pre-ordered with specified biamping and impedance settings.

NUGEN Audio offers Stand-Alone LM-Correct Loudness Tool
NuGen Audio now offers a new stand-alone version of its LM-Correct loudness analysis and correction tool.
NUGEN Audio, a creator of intuitive tools for audio professionals, has released a new stand-alone version of its LM-Correct loudness analysis and correction tool, which was originally only available as an AudioSuite plug-in. For the first time, LM-Correct is available as a file-based program, taking its speed and simplicity beyond the Avid digital audio workstation (DAW) environment. LM-Correct provides EBU R128|ATSC A/85 (CALM Act)-compliant loudness correction with unmatched simplicity, providing users with a rapid two-click solution for loudness normalization and conformance.
Part of NUGEN Audio’s range of innovative and easy-to-use loudness correction tools, LM-Correct is a faster-than-real-time tool that calculates and corrects for integrated program loudness and short-term maximum loudness. LM-Correct includes an internal true-peak limiter that transparently handles any intersample peaks.
LM-Correct’s settings include presets for current loudness standards, short-term loudness, overall integrated program loudness measurement and correction, maximum true-peak level targeting, and “EBU Mode.” The software also supports mono through 5.1 audio.
LM-Correct is available immediately for OS X and Windows operating systems. For more information about LM-Correct and other NUGEN Audio products, visit www.nugenaudio.com.
Saelig Introduces Handheld RF Spectrum Analyzer
Saelig’s PSA Series II RF spectrum analyzers feature long, rechargeable battery life.
Saelig Company has introduced the PSA Series II RF spectrum analyzers. Available in 1.3- and 2.7-GHz versions, these new instruments are smaller, lighter, and have a longer battery life than other more expensive handheld RF products. PSA Series II analyzers incorporate a 4.3” (11 cm) backlit thin-film transistor (TFT) color touchscreen display, with a high-capacity rechargeable Lithium-ion battery to produce more than 8-h operation per charge. The PSA Series II PSA1302 has a 1-to-1,300-MHz frequency range, while the PSA Series II PSA2702 operates up to 2,700 MHz. Dynamic range is 80 dB with a noise floor at –100 dBm. Resolution bandwidth is selectable down to 15 kHz.
The PSA Series II’s features include sweep modes (e.g., continuous, single, peak hold, and sweep average), AM/FM audio demodulation with built-in speaker, and data logging for traces, data points, or screen images (with storage for 10,000 entries per file triggered from a key press, internal timer, external trigger, or the limits comparator). Traces or complete screen images can be saved to file and compensation tables for antennae or other external transducers can be created and loaded. USB host and device connectors enable the use of USB flash drives or direct connection to a PC.
PSA Series II analyzers are controlled via finger-operated touchscreen soft keys in a hierarchical menu system that provides rapid access to menu functions. All functions can also be operated using just the hard keys.
The ruggedized casing incorporates a rubber protection buffer, a bench stand, and screen protection. For bench-top use, the instrument can be operated from its AC charger. For portable use, its 8-h battery life can be further extended by selecting auto-off, which turns the instrument off (retaining all data) after a selectable delay of 5 to 60 min. from the last key press. The compact, handheld PSA Series II RF Spectrum analyzers weigh 20 oz, making them suitable for any portable RF service kit. For more information, visit www.saelig.com.
