Shure ULXD4Q Quad-Channel Wireless Receiver with Radial Power Conditioner and BYFP Case
The Shure ULXD4Q Quad Channel Digital Wireless Receiver offers four channels of uncompromising audio quality, RF signal stability, and advanced setup features in a space-efficient single rack unit. Rugged yet lightweight and compact, the 1RU all-metal chassis houses four independent receivers, each with its own audio and RF meters, gain control, and XLR outputs that can be either direct or summed for flexible signal routing.
At only 7.6 pounds, the ULXD4Q offers space savings in the rack and cost savings when shipping. With RF cascade and two Ethernet ports, units can easily share RF signal and be networked together for simplified frequency coordination and deployment. For networked audio applications, Dante digital networking allows multiple channels of audio over a single Ethernet cable.
With the suite of features and benefits ULX-D® Digital Wireless Systems offer, the ULXD4Q is truly generations ahead of any other available receiver in its class, and brings a new level of performance and scale to professional sound reinforcement.
The Radial Power-2 rackmount power supply and surge suppressor gives musicians, engineers, producers, studio owners, commercial facilities, and anyone working with valuable electronic equipment protection from power surges that can damage or destroy music equipment instantaneously.
Unlike competitive products that utilize low quality MOV’s (Metal Oxide Varistors) for surge protection, Radial’s Power-2 is built using a USA made MOV. This critical component has been proven to offer superior thermal protection and have a much longer lifespan than the alternatives. An LED indicator on the front panel illuminates when the MOV is active, giving you visual confirmation that your gear is protected from voltage spikes.
Created with audio professionals in mind, the Power-2 employs shunt mode technology and avoids passing contaminated signals to the ground for lower system noise. Additionally, a high-rejection RF interference filter is used to keep high frequencies and AM radio signals out of the power line, preventing contamination of audio signals.
Additionally, the Power-2 can be used to illuminate the gear in your equipment rack, allowing you to make adjustments on the fly without the need to reach for a flashlight. An innovative sliding tray allows you to light up as much or as little rack gear as you like, using LEDs that provide a super-bright & evenly distributed light source. A dim knob is provided to adjust the brightness level, with an additional switch to vary the color of the LEDs between seven different options.
Eight rear panel outlets are provided (four with wall-wart spacing to accommodate any PSU size), along with a front panel outlet and a USB charging port to easily power personal devices. A heavy-duty power on/off toggle switch, rugged outlet connectors, and steel construction ensure that the Power-2 performs night after night without fail.
Featuring both injection molded cases and racks, our improved waterproof Fly Racks are lighter in weight and more affordable than previous models--all without compromising strength or durability.
SKB's injection molded rack frames are manufactured alongside our iSeries cases in Orange, California. Rack frames are removable and fit easily into SKB's iSeries cases, where they are protected by high quality PE foam that provides space for protruding knobs and buttons.
At less than half the weight of standard shock racks, SKB Fly Racks feature iSeries Watertight injection molded cases that are under 62 linear inches to keep from being oversized--the perfect solution for flying or shipping delicate equipment. Convenient in-line wheels and a push button release pull handle provides easy transport.
SKB iSeries Injection Molded Mil-Standard Waterproof Cases are molded of ultra high-strength polypropylene copolymer resin, featuring a gasket-sealed, water and dust tight, submersible design (MIL-STD 810G). Other standard features include a molded-in hinge, patented trigger release latch system, comfortable, snap-down rubber over-molded cushion grip handle, automatic ambient pressure equalization valve (MIL-STD-648C), and resistance to UV, solvents, corrosion, fungus and impact damage (MIL-STD-810F).
