AD4D Receiver - Fixed

The AD4D is a 1U rack-mounting, dual receiver that employs digital technology and true digital diversity to ensure high quality audio with a much reduced level of drop-out. Analogue audio outputs include independent balanced 3-pin XLRs with a dynamic range of over 120dB (A-Weighted, system gain +10), and a 3-pole, 6.35mm, jack output. Onboard digital outputs include AES3 and DANTE with a dynamic range of over 130dB (A-Weighted, system gain +10).

The rear facing panel of the AD4D houses an AC main input socket (IEC inlet) and an AC power output socket to link to a second receiver. This link socket can be exchanged for an optional DC power input for redundancy at point of order (1). A 4-port DANTE switch is situated to the left, offering four RJ45 connectors. The switch can be configured for use with control and audio, or separate streams with redundancy. Word clock in and out connectors have an adjacent termination switch. A single AES3 output carries the digital output of channels one and two audio, whilst each channel also has a dedicated 3-pin XLR output as well as 6.35mm 3-pole jack output. Line/microphone and ground lift switches are available for each analogue output. On the far right there are four BNC connectors. Channels A and B can be connected to antennas for RF reception; connectors C and D can be used to cascade the RF signal to additional receivers.

The front facing side has a 6.35mm jack, with associated rotary volume control, for the headphone output, 'enables DANTE Cue and DANTE Browse monitoring'. Two groups of indicators and controls are associated with channels one and two. Each has a six-stage LED meter for RF channel A and B and blue LEDs show the functionality of channel A and B. An eight-stage LED meter monitors the audio level being received. A large display screen shows a host of performance feedback including a 'channel quality' meter (RF signal to noise ratio), channel gain, transmitter battery life, RF channel and frequency. There are four function keys to the right of the screen that give quick access to the menu shown on the screen whilst a large, rotary, control knob and enter/exit buttons help to navigate the user-definable settings available. A power switch is positioned to the far right of the front panel. Rack mount fittings are not removable.

Note (1): The optional redundant power facility must be requested at time of order and may incur additional lead time. The IEC power link output is standard.

AD4Q Receiver - Fixed

The AD4Q receiver has the same functionality as the AD4D receiver but offers four reception channels. The receiver can be linked to two antenna for normal operation, or four antenna for 'Quadversity' mode, in which four remote antenna can be connected for optimum reception and much reduced drop out. This is particularly useful for operation within stadia or theatres where line-of-sight reception is not applicable, but also effective for multi-room broadcast operating from a central control hub such as in hotel presentation rooms or houses of worship. When running in 'Quadversity' mode, the BNC connectors usually used for cascading are used instead for the two additional remote antenna.

Each channel has a dedicated, balanced, 3-pin, XLR output and 6.35mm 3-pole jack output. However, if the AES3 outputs for channels 1 and 2 are used, they appear on the XLR output for channel 3, leaving only the jack output for the channel 3 analogue output. Likewise, the XLR output for channel 4 is utilised for the AES3 outputs of channels 3 and 4, so only the jack output is available for the analogue output of channel 4.

With the exception of two additional channels of monitoring, the front facing panel is the same as the AD4D.

SBRC-UK - Battery charger

This is a 1U rack-mounting, battery-docking station for up to four optional SBC-AX caddies, each capable of charging two SB900-B Lithium-Ion batteries. Batteries can be charged to 50 percent capacity within one hour and full capacity can be reached within three hours. A front panel display shows the state of charge for any inserted battery as well as estimated time until full charge in hours and minutes, percent of capacity display, or battery-health metrics including cycle count and percentage of original capacity. The rear panel hosts a single AC power input with latching rocker power switch. Also on the rear panel is a RJ45 Ethernet socket to connect to a network and thereby adding the ability to use Shure Wireless Workbench software to monitor it remotely. Weight: 4.4kg. Dimensions (HxWxD): 44 x 483 x 366mm.

Included accessories: IEC AC power cable, 3 foot Ethernet cable, rack mount hardware kit, 8x mounting screws for optional charger modules.

SBC-AX

Shure SBC-AX is a charging module compatible with the SBRC-UK battery docking station. It has the capacity to take two SB900-B rechargeable Lithium-Ion batteries.
