Discontinued Pre-Amplifier Cross Reference

MA-110

MA-110 - a surface EMG preamplifier with a gain between x270 to X380 made by Motion Control Inc., Utah. This device was used with our MA100 and MA200 EMG systems. This device is no longer manufactured by Motion Control for third-party EMG use.

The recommended replacement is the Z03-004 for surface, or Y03-004 for fine-wire applications. The Z03-004 and Y03-004 preamplifiers offer similar electrical performance to the MA-110 and, in addition, feature immunity to static discharge and RF interference.

MA-111

MA-111 - a surface EMG preamplifier with a gain of x300 made by B and L Engineering, California. This device was used with our MA100 and MA200 EMG systems.

The recommended replacement is the Z03-004 for surface, or Y03-004 for fine-wire applications. The Z03-004 and Y03-004 preamplifiers offer similar electrical performance to the MA-111 and, in addition, feature immunity to static discharge and RF interference.

MA-115

MA-115 - a fine-wire preamplifier designed by Motion Lab systems with a gain of x400 and built specifically for use with bi-polar fine-wire electrodes.

The recommended replacement for use with MA100 or MA200 systems is the Y03-004 which offers improved performance and reliability although with a lower gain (x300).

MA-310

MA-310 - a surface preamplifier with a gain of x20, and a frequency response from DC to 3,000Hz, supplied with a unique HARWIN connector used by the early MA300.

The recommended replacement for use with MA300 systems is the MA-411-001 offering improved performance and reliability, and, in addition, feature immunity to static discharge and RF interference.

MA-311

MA-311 (also MA-311H) - a DC-coupled, x20 gain, EMG preamplifier with differential inputs and built in band pass filter giving the device a frequency response from 15Hz to 3,000Hz and supplied with a unique 6-pin female HARWIN connector used by the early MA300.

Replaced by MA-411-001 offering improved performance and reliability.

MA-315

MA-315 - designed for fine wire & gel electrodes with a gain of x20

Replaced by MA-416-001 for fine-wire application while the MA-420-000 is purpose built for use with disposable snap gel electrodes with three snap leads. Both preamplifier designs offer improved performance and reliability over older models.

MA-316

MA-316 - designed for fine wire and gel electrodes. AC-coupled with a x20 gain and built in band pass filter.

Replaced by MA-416-001 for fine-wire application while the MA-420-000 is purpose built for use with disposable snap gel electrodes with three snap leads. Both preamplifier designs offer improved performance and reliability over older models.

MA-317

MA-317 - surface EMG preamplifier with x300 gain as a direct replacement for the older MA-110 design used by the MA100 and MA200 EMG systems.

The recommended replacement is the Z03-004 for surface, or Y03-004 for fine-wire applications.
