ConversDigital Provides DLNA-based Solutions for Connected Audio

Profusion distributes new line of networked audio components

Stand-alone audio devices are fast going the way of the compact cassette. Professionals and consumers want to play their media content wirelessly wherever they are, from any source, to any playbck device. And they want to control their audio from their smartphones, tablets, and dedicated controllers. So where does the savvy product design engineer go to get wireless network and control capabilities for their interconnected audio components?

The answer lies with the mconnect product line from ConversDigital, distributed by Profusion plc. The mconnect line has complete DLNA-based solutions (including the mconnect player, mconnect receiver, and mconnect firmware) to enable streaming from server devices or the Internet to playback devices on the local network, using smartphones or other devices as full-function controllers. mconnect solutions from ConversDigital make it easy to bring full interconnected audio functionality to products like wi-fi speakers and receivers, docking stations, component audio, automotive audio, and more.

The ConversDigital CDMCM-200 mconnect receiver module, for example, packs the following on a 35mm x 63mm PCB:

• DLNA/UPnP Compliant for audio playback
• Wireless (IEEE 802.11n) plus wired 10/100 Ethernet
• Supports Wireless Access Point and Wi-Fi Direct
• Option for bespoke iOS and Android Apps
• Audio input: MP3, ATRAC, WMA, WAV, FLAC, AAC, ALAC
• Audio output: I2S 16 bit up to 96kHz (24 bit support)
• RF: 2.4GHz, external antenna with diversity (typical range indoors 30m)

Also in the line are the EVM-MCM-20 Evaluation Board, CDMCA-300i mconnect player for iOS, CDMCA-300a mconnect player for Android, and CDMCSW-400 mconnect DLNA firmware. Note that the mconnect players can be custom branded.

Profusion Add Versatility With ICs from Dream Sound Synthesis

Continuing our commitment to bring you innovative, cost-effective design solutions, Profusion are proud to announce the addition of Dream Sound Synthesis to our lineup of premier component vendors. With an array of flexible sound synthesis and effects processor ICs, Dream offer quick-development solutions for keyboards, synthesizers, and other MI devices which require high-quality, customizable sound banks, sonic manipulation, and effects. Based on a set of programmable digital integrated circuits and their innovative sound synthesis technology, Dream's component line spans the range from high-quality to value.

SAM3816 Professional Audio Multiple Purpose Processor

Take the Dream SAM3816, for example. This recently-introduced device (a member of the SAM3000 family) includes sixteen 24-bit DSPs with double-precision instructions, 24-bit audio routing (8 I/O per DSP) and a general-purpose 16-bit processor, along with 16-input and 16-output channels, and a variety of I/O formats (USB 2.0 Full Speed, DDR SDRAM, SDR SDRAM, Wave ROM, NAND Flash and DataFlash®). Sampling rates up to 144 kHz at 24 bits are supported. On-chip flash memory allows copy protection of program code and sound banks.

Firmware development on the SAM3816 is simplifed by an optimized instruction set and a C compiler, speeding time-to-market for audio applications, especially when multi-tasking processes like synthesis, mixing, routing, and the like are required. All of this is supported by reference designs, easy-to-use development tools, various sound banks and efficient technical support.

SAM2195 Low-Power Single-Chip Synthesizer with Effects

Or how about the SAM2195 (part of the SAM2000 family), a complete, single-chip, low-cost, low-power MIDI sound system. This well-designed component produces outstanding synthesized stereo output using a full GM sound set, along with a range of compatible effects, from standard MIDI signals fed to its serial or parallel inputs. The SAM2195's low power consumption makes it ideal for all battery-powered applications, such as portable Karaoke devices or other products using MIDI synthesis.

To get your hands on the SAM3816, SAM2195, or any of the other exciting ICs from Dream Sound Synthesis, please contact one of the Profusion sales offices near you.

Profusion Expands Component Line-up With Abletec

Scandanavian design firm provides audio-specific power supplies and Class-D amplifier solutions

Audio design engineers are an inventive bunch, with individual and creative ideas about how sound should be created and perceived. While there are many areas where agreement might be hard to come by, two characteristics which most designers value very highly are "simplicity" and "functionality".

These adjectives are closely associated with Scandinavian design philosophy, and Abletec, an innovative power supply and power amplifier design and manufacturing company based in Norway, provide components that exemplify these qualities. Profusion are pleased to announce the addition of Abletec products to our growing line of specialty audio component manufacturers.

Take Abletec's line of excellent Class-D amplifier solutions. Their ALC power amplifiers — with rms outputs ranging from 180 to 1000 watts with >85% efficiency — are based on a phase shift modulated topology which exhibits very low distortion and can be configured in both stereo and bridged mono configurations. The open frame designs include robust switch mode power supplies for excellent continuous and peak power delivery. Each module incorporates Abletec's advanced, dual-mode protection circuitry.

Looking for a reliable, capable power supply for your next product design? Abletec's ALP power supplies, designed specifically for use in auido components like Class D amplifiers are available in continuous (5 minute) power ratings from 50W to 960W. Abletec's supplies provide low ripple — essential for open-loop amplifier designs — along with compact size, high peak wattage, high efficiency, and graceful protection and auto-recovery. All Abletec power supplies meet FCC, UL, CSA and CE requirements.
