With ADI’s ADXL320 iMEMS accelerometer, Source Audio’s Hot Hand™ guitar controller puts the power of pedal effects into the hands of musicians.

Norwood, MA (04/10/2006) - Musicians in search of more control over the creative process have a new way to manipulate their guitar effects thanks to the new Hot Hand™ guitar effects controller from Source Audio LLC and iMEMS® Motion Signal Processing™ technology from Analog Devices, Inc. (NYSE: ADI). Incorporating ADI’s tiny ADXL320 iMEMS accelerometer, the Hot Hand controller attaches easily to the picking hand of any guitarist. By sensing the musician’s hand or finger motion, Hot Hand allows the guitarist to manipulate sound effects using an interface console that includes 11 “wah” type filter effects. Eliminating the need for pedals or similar devices, the Hot Hand guitar effects controller opens a new avenue of artistic expression for musicians.

"Guitarists are near-obsessive gadget freaks, and the Hot Hand was definitely one of the coolest and most innovative sonic tools debuted at the 2006 Winter NAMM Show," says Michael Molenda, Editor in Chief of GUITAR PLAYER magazine. "Allowing players a way to incorporate physical gestures into effects control will absolutely thrill adventurous players looking for new and unique ways to manipulate sound."

“ADI’s small, low-power iMEMS accelerometer enabled a controller small enough to easily fit on a finger of the guitar player’s picking hand,” commented Roger Smith, president, Source Audio. “The whole idea of Hot Hand is to change the way guitarists manipulate effects without anchoring them to traditional pedal-effects consoles or other fixed on-stage devices.”

At the core of the Hot Hand™ motion sensing system is Analog Devices’ dual-axis iMEMS accelerometer. The ADXL320 has a typical measurement range of ±5g and will accurately measure the wide range of motions generated by a guitar player’s hand. Mounted in a ring on a user’s strumming hand, the accelerometer’s x- and y-axis analog outputs provide measurements for both movement and tilt. Hand or body movements now become the expression pedal. Also, at the heart of the interface console is ADI’s SigmaDSP audio processor, a powerful 56-bit audio processor with 24-bit analog-to-digital converters and digital-to-analog converters that offer better than 100-decibel dynamic range. The SigmaDSP audio processor features a 56 bit fixed point multiplier/accumulator, on-board data and program memory, clock generation circuit, and special acceleration blocks for many common audio processing macro-functions (such as filters).

Bill Giudice, vice president and general manager, Micromachined Products Division, Analog Devices added, “Innovative customers like Source Audio continue to demonstrate the enormous potential of Analog Devices’ iMEMS motion signal processing technology for a wide variety of consumer products.”

About the ADXL320
The ADXL320 *5g dual-axis iMEMS accelerometer with signal-conditioned voltage outputs is among the smallest low-power accelerometers available. Available in a small, thin 4mm x 4mm x 1.45mm plastic lead-frame chip-scale package (LFCSP), the device operates on power supplies as low as 2.4 V with typical supply current of only 350 μA, and can be power-cycled for even greater battery life. The typical noise floor is 250 μg per rtHz, allowing small tilt changes to be sensed using the narrow bandwidths (<10 Hz) typical of human motion. Bandwidths of 0.5 Hz to 2.5 kHz may be selected to suit the application.
