AMIX – SNA50-3R

SNA50-3 is a global limiter. The technology used for the sound limitation does not degrade the signal dynamics at all, as a traditional compressor would do.

The pressure measurement by the acoustic sensor is transmitted to the computer which integrates the modulation peaks with a progressive slope, adjustable in rise and fall time.

• Balanced inputs/outputs compatible unbalanced.

• Limitation in global level.

• Limitation either by acoustic sensor or by electrical analysis of the input signal to SNA50-3, while keeping the acoustic level measurement for the history.

• Visualization of the levels and parameters on a touch screen on the front panel.

• Real-time display of the Leq1s in global level.

• Choice of A and/or C weighting for the acoustic analysis of the global level, the C weighting allows the bass to be taken into account.

• Recording of global levels: LAeq 1min, LAeq 10min, LAeq 15min, LCeq 1min, LCeq 10min, LCeq 15min, LpcC1min max.

• Automatic summer/winter time change-over.

• Embedded web server for history consultation and setting equipment.

• No specific software required.

• The internal memory is sized to store sound level values 24 hours a day, 7 days a week for 6 months.

• USB Host connector allowing the connection of a USB key for history collection.

• Fire contact with audio level attenuation > 40dB.

• Acoustic and electric auto-verification of the measuring sensor.

• VCA technology (Voltage Controlled Amplifier), no audio signal cut-off.

• SNA50-3 can be sealed.

BARE – BE-0404D

The network audio processing center is a network audio processor with 8 inputs (4 analog and 4 digital) and 8 outputs (4 analog and 4 digital), using the industry-leading ADI DSP SHARC21489 chip, The highest operating frequency can reach 450MHz. The input and output modules of DSP can be customized according to the actual situation. At the same time, it has independent AFC, AEC, ANS, AGC, gain sharing automatic mixing, threshold automatic mixing and other processing modules to meet the needs of audio processors and transmission in various places. Such as meeting rooms, multi-function halls, conference center auditoriums, administrative centers, etc.

RDL – DDB-BN31

The DD-BN31 is a complete wall-mounted Dante audio network interface. It features two XLR mic or line inputs, one stereo Mini-jack line input and one stereo Mini-jack line output on the front panels, plus two line outputs on a rear-panel detachable terminal block.  The DD-BN31 is a complete wall-mounted Dante audio network interface. It features two XLR mic or line inputs, one stereo Mini-jack line input and one stereo Mini-jack line output on the front panels, plus two line outputs on a rear-panel detachable terminal block. Special software is not required to configure the DD-BN31. Each XLR input provides three switches that may be set from the front of the unit when the cover plate is not installed. One switch enables or disables P48 phantom for that input; the second switch selects the mic or line gain range; the third switch sets the gain. The Mini-jack input provides a switch to configure the input for stereo or summed mono. The Mini-jack output provides a switch to configure the output for stereo or left-channel mono. Each rear-panel output provides a switch to set the output to balanced professional or unbalanced consumer level. The DD-BN31 fits a standard US dual-gang electrical box or an RDL WB-2 back box for installations in thinner European or equivalent walls. The DD-BN31 is PoE powered, and is available in multiple finishes with optional customized graphics. The two XLR inputs are each converted to a separate Dante network transmit channel. Three gain settings are switch-selectable for both the mic and line input ranges to match condenser or dynamic mic levels and standard line levels. The Mini-jack left and right inputs are each converted to a separate Dante network transmit channel. Each input provides a network digital audio level of -18 dBFS for an unbalanced -10 dBV input. The input is equipped with a selector to sum the left and right Mini-jack inputs. The summed signal feeds both Dante transmit channels. Two Dante audio channels are converted to unbalanced line level to feed the front-panel Mini-jack. Each channel provides -10 dBV unbalanced for a network digital audio level of -18 dBFS. The left and right Mini-jack channels are normally fed from Dante receive channels 3 and 4 (stereo). The Mini-jack output is equipped with a selector to feed both output channels from Dante receive channel 3 (mono). This selector may be set from the front of the unit when the cover plate is not installed. Two Dante audio channels are converted to balanced line level on the rear-panel detachable terminal block. Each output provides +4 dBu balanced for a network digital audio level of -18 dBFS. Each output is equipped with a selector to unbalance the audio and attenuate the level to -10 dBV. These switches are located on the top of the chassis and are set by the installer prior to mounting the unit. The rear-panel outputs are intended for connection to RDL AMS connectors mounted in Decora-style plates that match the DD-BN31. AMS audio connectors include RCA, Mini and XLR jacks. The output plate may be located together with the DD-BN31 in a triple gang box or may be mounted remotely in a single box. Valid PoE power and synchronization to the Dante network are indicated by green LEDs visible from the front of the unit. The DD-BN31 is a professional grade product with discrete mic preamplifiers for studio quality fidelity and low noise performance, coupled through metal XLR jacks housed in a stainless steel chassis with dual powder-coated or stainless steel Decora front plates. The DD-BN31’s superior performance specifications make it ideally suited to the most demanding installations, and an exceptional value in commercial networked audio systems. This full-featured product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. Designed to outperform. Built to last.
