HPV Magnetic Array Device (MAD) Panel Array System
|
|
 |
Magnetic Audio Device (MAD), from HPV Technologies, is a surface array technology utilizing full-range planar magnetic drivers that are assembled and interact to create a single configurable plane of radiating energy. MAD loudspeaker arrays can be constructed as required for various applications, and develop array coupling and pattern control behavior in both horizontal and vertical domains. Each array panel utilizes neodymium magnet assemblies and requires no cabinet, crossover, time-offset correction, mid- and low-frequency cone drivers or compression drivers. |
Frequency response and output is determined by array size, output power requirements and program material, and typically ranges from 60 Hz to 20 kHz. Optional dipole subwoofers are available for LF extension. MAD drivers are wired in series-parallel, presenting amplifiers with a 4-ohm impedance load per row.

It is rated as delivering maximum power handling capacity of 1,000 watts (AES) and capable of 98.5 dB maximum output (1 watt/1 meter). Other details include a die-cast aluminum basket, dual demodulation rings, double silicon spider design, a new ventilated magnet structure, 4-inch copper voice coil wire, poly-cotton triple-roll surrounnd and an Aramid fiber-loaded cone with proprietary weatherproof coating. |
ARX EQ 260 Graphic Equalizer
|
|
|
The ARX Systems EQ 260 is a dual-channel, one-third octave graphic equalizer. Each channel offers 30 of the company’s new Extended Resolution long-throw, center- grounding sliders, switchable to either ±15 dB or ± 6 dB. A gain control offers up to +10 dB of gain and a clip LED indicates circuit overload. |
Also included is a sweepable 20 Hz to 200 Hz high-pass filter, and an in/out hardwire bypass switch with optional transformer output. The EQ 260 is specified as providing signal-to-noise ratio of 95 dB, while unweighted dynamic range is listed at 120 dB and distortion is rated at less than .004 percent at 100 Hz, 1 kHz and 10 kHz.
Martin Audio W8LS Line Array Subwoofer
|
|
|
The Martin Audio W8LS line array subwoofer is designed to augment the low-frequency output of the W8L full-range line array system in large-scale applications where the sub-bass enclosures must be flown. Its physical characteristics (51.7 inches by 19.3inches by 29.7 inches) are identical to the W8L and it offers the same proprietary rigging system, with variable splay angles to match W8L column curvatures. |
The W8LS offers a dual long-excursion 18-inch direct radiator design and is rated to produce 138 dB continuous and 144 dB peak. Extended frequency response is stated as 32 Hz to 180 Hz (±3 dB), with useable response to 28 Hz (-10 dB). The drivers are reflex loaded by ports at either end of the enclosure and substantial internal bracing is employed to minimize energy absorption by the cabinet walls at the high pressures generated within the enclosure itself. W8LS subwoofers are designed to be powered by Martin Audio MA 4.2S power amplifiers.

Upgraded Denon DN-T625 Combo Deck
|
|
|
The Denon DN-T625 CD/Cassette combination deck offers updated cassette recording and playback functions. With the addition of RS-232C control, it is a full integration source unit able to be controlled by remote systems such as AMX and Crestron. |
The CD mechanism is able to support playback of CD and CD-R/RW formats, offers single and continuous playback modes, program play (up to 99 tracks) and three repeat modes (single track, all tracks, A-B) for continuous playback.
The unit is also able to display CD encoded text through the use of a highly visible FL tube display. Pitch change of up to ±12 percent is available. The cassette record and playback functions include Dolby B/C noise reduction. The REC input source is switchable between internal CD (with CD deck synchronized recording) and external line input (XLR and RCA balanced/unbalanced).
D-PAC Audio MP-152 Stage Monitor
|
|
|
The D-PAC MP-152 is a low-profile stage monitor wedge that can be configured for either passive operation or biamped through a digital signal processor. Weight is lowered through use of neodymium drivers, while a carefully selected crossover point helps with point-source reproduction. Sound pressure levels rated at 133 dB can be reached through inclusion of a 15-inch driver with interleaved voice coil for enhanced heat dissipation, as well as double demodulation rings for improved power transfer in the magnetic circuit. The MP-152 can also be pole mounted for main system applications. |
Shure DFR22 Digital Signal Processor
|
|
|
The Shure DFR22 digital signal processor is a 2-input, 2-output unit with the company’s patented automatic digital feedback reduction algorithm (DFR). |
It also includes modules for equalization, dynamics processing, delay, and matrix mixing and is configured through a drag-and-drop Windows software interface.
The DFR22 offers single-channel and stereo 5-, 10-, and 16-band DFR processing blocks. An auto clear mode removes changes to equalization made by the feedback reducer after a specified period of time. Both XLR and Phoenix connectors are included.
Sabine 2.4 GHz True Mobility Wireless Mic System
|
|
|

All SWM7000 systems come with remote control software. SWM7000-ND Series receivers include both analog and digital audio outputs and allow for networking of up to 70 channels (one transmitter per channel) using a single computer.
Peavey KOSMOS PRO Processor
|
|
|
The Peavey KOSMOS PRO is a low-frequency energy and stereo image enhancement system also intended to add definition to audio sources. The unit’s QUAKE sub-harmonic generator analyzes the source material’s bass frequencies, then generates additional low frequencies an octave lower. |
THUD provides an additional bass boost an octave higher than the original bass track to fill in the low end, while XPANSE intensifies the left-right stereo image.
The STRATOS function clarifies the upper high register, and Barometric Shift, which tunes the XPANSE range. Other controls include a “Deeper” switch for altering the THUD range and a “Dynamics” control for tailoring QUAKE for tight or loose response. Switchable input/output meters assist with matching levels.
Drawmer SP2120 Loudspeaker Protector
|
|
|
The Drawmer SP2120 Loudspeaker Protector is designed to help eliminate damage from excessive sound pressure levels on loudspeaker systems and to assist with compliance to noise level restrictions. |
The SP2120 is intended for insertion in the sound system immediately prior to the amplifier stage. Its signal path combines a mixture of ‘multiple time constant’ circuitry and automatic gain control (AGC) that allow small overloads to sound louder, even when they are not.
The front panel of the 1U, two-channel processor includes an integral security lock to ensure that only key holders may make adjustments to the maximum volume levels. In ‘unlocked’ mode, two front panel pre-sets are available for adjustment by the installer. The first calibrates the 16-segment left/right bar graphs and the second sets the absolute volume level to which the system is allowed to perform. If the SP2120 receives increased signal levels, a transparent protection circuit is activated which maintains the specified volume level without degradation in sound quality.
Symetrix SymNet Software v3.5
|
|
|
Symetrix has upgraded the SymNet Audio Matrix system with the version 3.5 release of SymNet Designer application software and new Control I/O hardware. Improvements to the software include basic time alignment to compensate for DSP latency within the SymNet hardware, a volume ramp-up after downloading for loudspeaker protection, and increased interactivity between Adaptive Remote Control (ARC) units connected to a SymNet system. |
Graphic EQ processing modules in mono and stereo, and automatic verification of firmware in the SymNet hardware units when bringing the system online with a Windows PC are also included in this software upgrade. Version 3.5 will support a new hardware device known as Control I/O. Intended to be connected to a SymNet ring via RS-485, this unit offers expanded external control options through the eight analog control inputs, eight open collector outputs with +5 volt pull-up resistors, four control relays, RS-485 port, four Adaptive Remote Control (ARC) ports, and 15-pin “joystick” MIDI port.
