PUBLIC-ADDRESS SYSTEM

The Anchor Audio MiniVox public-address system is capable of delivering 108dB of intelligible speech from one small, self-contained portable sound system designed for users with no technical knowledge. The UHF microphone has a range of 250ft. from the receiver. The system weighs 5lbs. including its wireless receiver, and it is powered by nine C-cell batteries.

PREAMP

The Parasound NewClassic series for custom installations now includes the Model 2100 stereo preamp. The Model 2100 includes seven line-level inputs, one of which can be switched to a phono input with correct gain and load impedance for both MM and MC phono cartridges. Additionally, it features a front-panel input jack for MP3 players with an automatic 12dB gain offset to match the volume level of an iPod with other source components. The preamp also includes analog bass management and creates a sub-out channel with a low-pass filter that is continuously adjustable from 40Hz to 140Hz.

SUBWOOFER

With a 3,200W peak power output, the Peavey SP FH folded-horn subwoofer was designed for demanding low-frequency sound-reinforcement applications. The sub uses an 18in. Low Rider Black Widow loudspeaker with a 4in. voice coil and Kevlar-integrated cone. Ideal for use in large concert productions, the SP FH registers a focused frequency response from 30Hz to 300Hz and 1,600W of program power. The unit has a nominal impedance of 8V and built-in casters for easy transport.

DIGITAL WIRELESS SYSTEM

The X2 XDR95 multichannel 24-bit digital wireless system is purpose-built for live musical performances — from studio to stage, clubs to arenas. The system features proprietary companderless TruDigital format and new Q-DiversityPlus (anti-jamming) technology for the sound and feel of a direct wire connection with a 300in. operating range. A 24-bit A/D converter at the XDT4 body-pack transmitter captures the full dynamic range of incoming instrument, line-level, or microphone signals, and then transfers them in digital format on two separate RF carrier frequencies (odd samples on one, even samples on the other). The XDR4 receiver decodes the signals back into analog audio via a 24-bit D/A converter.

MICROPHONES

The Micropods from Audix consist of a 6in., 12in., or 18in. gooseneck with an M1250 or an M1280 microphone attached. Both these mics are immune to RF, which allows you to use them freely without picking up any interference. The Micropods are normally used with the ATS10 heavy-duty, shock-absorbent base, which is great for public speaking.

AMPLIFIERS

QSC PowerLight 3 series amplifiers offer a choice of DSP with remote control and monitoring via BASI, or straightforward analog input operation. The 8,000W-model PL380, operable between 20Hz and 20kHz, combines a pair of 4,000W Class-D amplifier channels with a QSC PowerLight power supply to serve up more than twice the audio horsepower of any previous 2RU PowerLight amplifier. Models PL325 and PL340 in the series are designed for use in lower-power applications. Both amplifiers share the same feature set as the PL380. Every PowerLight 3 model has the capacity to double long-term average power without dumping hot air into the rack, and every model is built in the same chassis size. Other features shared across the line include detented gain controls with 1dB increments and three selectable input gains of 1.2V, 32dB, or 26dB.

The Audix MicroBoom is an innovative solution to stage- or platform-mic positioning. Whether it is for choir, theatrical production, or presentation, you can now strategically place your microphones without having to permanently hang them. The MicroBoom is a 50in. carbon-fiber rod that can be used with any condenser microphone in the Micros series. It weighs just 2.5oz., and it can be adjusted to almost any position necessary for use on almost any miking application.
