A Tradition of Value

The UC Wireless is the latest in Shure's full line of proven wireless systems and other products designed for the installed sound professional. Each one comes with unparalleled service and support. Which is precisely what you've come to expect from 70 years of leadership in state-of-the-art sound reinforcement products.

Shure Antenna Distribution UA845:

Expandability. The UA845 UHF Antenna Distribution

System is designed for large UHF wireless systems.

Each unit allows up to four wireless receivers to use the

same two antennas, and the CASCADE ports allow

connection to a fifth receiver or a second UA845.

Compatibility. The UA845 is compatible with all Shure

wireless microphone receivers operating within a com-patible

frequency range (see UHF Carrier Frequency

Ranges in the Specifications section).

CASCADE Ports. Two 50 W, BNC-type antenna CAS-CADE

ports allow an additonal UA845 unit or a fifth

wireless receiver. A large wireless system can be run

off of a single pair of antennas.

Power OUTPUT and OUT Connectors. Up to five (5)

U4 receivers can be daisy-chained and powered from a

single source via the Power OUTPUT connectors. Up

to four (4) UC4 receivers can be powered from the

UA845 using the 12 Vdc OUT connectors.

Low Noise and Intermodulation Distortion. The

UA845 maintains clean signals with minimal distortion.

Insertion Loss Compensation. Whenever a signal is

split to multiple output ports, there is a loss in signal

strength. The UA845 amplifies signals to compensate,

ensuring a strong signal to the receivers.

Front-Mounted Antennas. The UA845 comes with

hardware to front-mount the antennas, if desired.

BSS 9088LL SoundWeb:

6.1 9088 Networked Signal Processor

The 9088 Networked Signal Processor forms the heart of the Soundweb system. In a single rack space unit, it offers 8 analogue audio inputs, 8 analogue audio outputs, 160 MIPS of digital signal processing, a pair of network jacks, and a variety of control options.

The front panel of the 9088 has a number of LEDs to allow a quick view of activity on the audio inputs and on the network. It also has a mini-DIN connector for an RS-232 serial port: this is normally used to connect a PC for system setup and control

The rear panel contains the audio inputs and outputs and the network jacks. It also contains a second RS-232 port, which is normally used for control from an external controller such as AMX or Crestron. Finally, it contains a control connector: see section 4 Control options for a description of how this is used. Both control i/o and analogue i/o connections are made via "Phoenix" style two-part screw terminals; the female connectors are shipped with the Soundweb unit, so installation can be made with no soldering and no extra connectors to buy.

The 9088 contains two preamplifier cards for the analogue inputs: each card handles four of the inputs. Two types of card are available: the line card and the mic/line card. The line card gives a choice of two gain settings: 0 dB and 12 dB (intended as a pro/consumer switch). The mic/line card provides a range of gain settings from 0 dB to 72 dB, together with phantom power and phase reverse. In all cases, each input can be switched individually.

The analogue outputs are equipped with analogue attenuation after the DAC stage. If the unit is used at anything lower than its full output level, it makes sense to apply the final gain reduction in the analogue domain: in this way, the DAC noise is also attenuated and the signal to noise ratio is kept at a maximum.

The core of the 9088 contains two Motorola 56301 DSP chips, running at 80MHz each and thus providing a total of 160 MIPS of DSP. There is also a block of dynamic RAM allowing a total of 11 seconds of audio delay. The main control processor is a Motorola 68000-series CPU, which runs a real-time multi-tasking operating system; this CPU takes care of system operation and interfacing and performs all the necessary housekeeping functions. Finally, the core contains a flash EPROM (see section 5 Flash EPROM storage), in which is stored all of the software to run the unit, and also the unit's configuration.

Meyer Speakers:

The CQ™ products are self-powered reinforcement loudspeakers that come in either a high Q or low Q configuration. As a high Q loudspeaker, the CQ™-2 covers 50°H x 40°V, while the CQ™-1 covers 80°H x 40°V. The amplifier and control electronics are fully contained within the compact speaker enclosures. "CQ" stands for "Constant Q," meaning that the distribution of acoustic energy is very evenly distributed over the coverage pattern in both the horizontal and vertical axes, while the energy outside the coverage area is low. This provides extremely tight control and predictable results for venues in which acoustic spill-over is to be avoided.

The CQ's incorporate the Intelligent AC™ system, which performs automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression. All that is required for full operation is the application of AC power and an audio source. The unit's TruPower Limiting™ driver protection technology offers longer driver component life when units are run at extreme levels for extended periods. The cooling, power supply, and amplifier subsystems are all built for maximum efficiency and reliability. However, if servicing is required, it is facilitated by the modular design. The units can be fitted with the Remote Monitoring System (RMS™), which allows the operators to monitor such system parameters as signal and power levels, limiter activity, amplifier heatsink temperature, and cooling fan status.

The PSW-2 is a self-powered, dual-amplified, 4th order bass-reflex subwoofer which is arrayable and flyable (with optional rigging). The dimensions of its trapezoidal cabinet are identical to those of the MSL-4. The unit incorporates twin 15" drivers, has a frequency response of 35 Hz to 120 Hz and is phase-corrected.

The amplifier, controller, power supply and cooling subsystems are integrated into a lighweight module, service accessible at the back of the enclosure. Self-contained electronics eliminate the need for equipment racks. The PSW-2 is compact for efficient transport and setup.

The PSW-2 power supply incorporates the Intelligent AC ™ system, which performs automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Simply connect a signal source and plug into power anywhere worldwide and the unit is fully operational.

The amplifier unit is equipped with TruePower ™ Limiter technology, which maximizes speaker protection reliability and component life. This breakthrough in speaker control also results in higher SPL at all frequencies and increased available headroom. Long term power compression, typically 3-6 dB in conventional systems, is less than 1 dB. Maximum SPL capability remains constant even during operation at high levels for extended periods.

PSW-2 performance can be supervised using the Remote Monitoring System (RMS ™). This enables users at a computer terminal to monitor such parameters as limiting activity, power output, voltage, temperature, fan speed and driver status.

The Meyer UPA-P Series self-powered loudspeakers (UPA-1P, UPA-2P) are more than powered versions of the Meyer UPA-C Series (UPA-1C, UPA-2C). The UPA-P Series features phase-corrected electronics that produce flat acoustical phase and amplitude responses, resulting in exceptional system impulse response and precise imaging. Despite the inclusion of amplification and control electronics, the UPA-P is the same size as, and only 10 lb. heavier than the UPA-C. Additionally, the UPA-P's advanced horn designs achieve a consistent polar response and smooth arraying behavior.

The beamwidth of a horn is the angle at which the sound pressure at a given frequency decreases to half (-6 dB) its on-axis amplitude. Existing technologies produce horns whose beam width varies over the operating frequency range. These horns also display nonuniform frequency response within, and significant side lobe energy outside their beam width. Both undesirable characteristics, particularly prevalent for horns with a wide beamwidth, make array design extremely problematic.

The UPA-P horns exhibit constant Q: the beamwidth remains consistent across the horn's operating frequency range in both the vertical and horizontal planes. The UPA-2P uses the same horn as the UPA-2C: the original design achieved constant Q for its narrow beam width (45°H x 45°V). Meyer Sound developed the UPA-1P horn in an anechoic chamber by measuring coverage patterns using angular and frequency resolutions of 1° and 1/36 octave, respectively. The UPA-1P horn provides a much wider horizontal, and slightly narrower vertical beam width (100°H x 40°V) than the UPA-2P. Both speakers share the following remarkable attributes:

The UPA-P Series is ideally suited for small PA applications requiring complete coverage with a compact, high-powered system, and also make excellent under-balcony, down-fill, and keyboard speakers.

The UPA-P's integrated electronics employs the Intelligent AC power supply, which auto-selects the correct operating voltage (facilitating international use), suppresses high voltage transients, and provides soft-start power-up (eliminating high inrush current).

The UPA-P can be equipped to operate with the Remote Monitoring System™ (RMS) network and software application. The UPA's are shipped with one of two audio input and control options. The Basic module contains an XLR input and a loop connector.

The second module provides features that facilitate array building and integration into full-range systems without incurring the cost of external processors. These interchangeable modules can be installed in the field with a Phillips screwdriver. RMS displays signal and power levels, driver and cooling fan status, limiter activity, and amplifier temperature for all speakers in the network on a Windows™-based PC.

The UPM-1P is a compact, self-powered professional sound reinforcement loudspeaker system. Versatile and powerful, its bi-amped, three-way design incorporates dual 5-inch low/mid transducers, a 1-inch titanium dome HF driver on a symmetrical 100° horn, a two-channel power amplifier, and Meyer Sound's proprietary phase-corrected active processing circuits.

The UPM-1P is ideally suited to applications requiring high sound pressure levels, extremely low distortion, and uniform directional control. Stand-alone, the UPM-1P will provide vocal range reinforcement as a small PA system, in under-balcony, front- or side-fill applications. A full-range system can be created with the addition of a separate optional subwoofer.

Like all Meyer self-powered loudspeaker systems, the UPM-1P exhibits superior performance across virtually all parameters. Because the amplifiers and control electronics are optimized for each driver, the system is able to produce more power with a flatter response and lower distortion. The self-powered concept simplifies installation, eliminates amplifier racks and external drive processing, and can create extensive distributed systems free from the signal losses imposed by long loudspeaker cable runs or 70/100V wiring schemes.

UPM-1P's constant directivity HF horn affords a 100° beam width, and sophisticated phase-correction circuitry assures true point-source performance without the off-axis cancellation effects that plague customary dual-woofer designs. Two MS-5 low/mid-frequency transducers are driven in parallel to take advantage of their combined acoustic output. To prevent destructive interference due to comb filtering effects in the critical mid-band frequencies, one of the drivers is passively rolled off above 500Hz. Two channels of power amplification are provided, along with an active crossover, driver protection voltage limiters, and frequency and phase response alignment circuitry. A laser-trimmed differential input stage affords superior common-mode rejection to allow signal runs through a simple twisted pair cable. Rear panel LEDs indicate AC power and driver protection limiting. The UPM-1P's integral power supply suppresses high voltage transients. Two PowerCon AC connectors are provided to facilitate AC looping.

The rugged cabinet is coated with a textured black finish. It has three 3/8"-16 threaded recessed nut plates, and may be mounted on a stand. Optional mounting hardware is available. The UPM-1P easily integrates with the Remote Monitoring System™ (RMS) network and software. RMS displays signal and power levels, driver and cooling fan status, limiter activity, and amplifier temperature on a remote PC. The UPM-1P can be supplied with either the standard audio input module incorporating looping XLR connectors, or an alternate that adds attenuation and a polarity switch.
