Profusion Introduces Summit Wireless Audio Technology

While consumers have come to expect persistent improvement in video quality through home theatre, far too often the quality of built-in audio is becoming compromised, with ultra-thin sets providing limited space for high-quality speakers.

Summit Wireless Audio Technology

Consumers serious about their home cinema setup will be expected to invest in a separate audio system. But they often run into the problem of setting up multiple speakers and, in the case of Surround Sound systems, getting as many as eight cables to blend naturally into their environment. Furthermore, it’s believed that many consumers fail to fully calibrate and balance their sound system to its environment, and find relocating speakers time consuming and/or expensive.

Easy to Set Up and Optimise, with Limitless Audio Expandability

Looking to the future, Profusion is proud to add Summit Semiconductor's wireless surround sound technology to its line-up.

Summit Semiconductor's range of Wireless Audio ICs enable wireless 7.1 home theatre audio. Superior digital audio fidelity, WiSA compatibility, and such innovative features as automatic calibration ensure that consumers no longer need to hire a professional to set up their home cinemas.

  • Wireless technology allows seamless scalability and interoperability in home audio. Consumers can upgrade their system however and whenever they choose, from stereo to 7.1 Surround Sound, free from the hassle and clutter of speaker wires.
  • High quality 24bit uncompressed audio, offering the highest real-time audio rendering possible (48/96KHz).
  • Low end to end latency of 5.2ms at 48kHz, with each channel in sync and virtually no phase drift between channels, so that the sound image is reproduced accurately as the artist intended, and with no lip sync issues.
  • Automatic audio setup and single button “sweet spot” location programming allows even the amateur enthusiast to enjoy highest quality audio.
  • Up to 24 channels of interference resistant UNII band wireless guarantees no crackles, pops or drop outs; a growing concern in WiFi-congested environments.
  • Supports Blu-ray and other high bit rate HD content with patented audio recovery.
WiSA wireless audio standards

Global Standardisation with WiSA Compatibility

Summit Wireless Audio products are fully compatible with WiSA ( standards, allowing consumers to upgrade and expand their Surround Sound systems with audio components from a wide range of leading manufacturers.


New Lower-Cost Preamp from THAT Corporation

THAT1583 Expands Options for Mic Pres, Summing Amps, Instrumentation

THAT1583 app circuit

When it comes to IC microphone preamps, nobody innovates like THAT Corporation. THAT's ground-breaking THAT1570 remains the standard for high performance in a current-feedback amplifier suitable for differential mic pre and bus summing applications. Now, THAT has released the reduced-cost THAT1583, giving designers another option for incorporating the reliability, manufacturability, ease of design, and excellent sound quality these preamps represent.

Like the THAT1570, the 1583 mates perfectly with THAT's series of Digital Preamplifier Controller ICs to produce an optimized, digitally controlled preamplifier. As well, the 1583 improves on traditional current-feedback designs by offering a more versatile configuration that can yield lower noise at low gains, lower distortion overall, and higher slew rate.

The THAT1583's pro-quality specs include:

  • Low noise (1.9 nV/root-Hz @60 dB gain)
  • Low THD+N (0.001% @ < 40 dB gain and 0.006% @ 60 dB gain)
  • Wide Bandwidth (1.7 MHz @ 40dB gain)
  • High Slew Rate (50 V/micro-sec)

All this with a low current draw of 7.0 mA typical. Gain is adjustable from 0 to >60 dB and the THAT1583 comes packaged in a space-saving QFN16 package.

For more information about the THAT1583 and other solutions from THAT Corporation, contact a Profusion sales office near you.

SAM3816 Professional Audio Multiple Purpose Processor

Block diagram of SAM3816

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.
