EC1/ES1 artifact picked up by electrodes

Tech Note: TN0112
Product: EC1, ES1
Version: < 3000
Date Added: 2004-03-02


There is a direct electrical pickup of the acoustic signal from the EC1/ES1 by both high and low impedance electrodes.


EC1s and ES1s with serial numbers greater than 3000 have been modified to decrease direct pickup by about 6 dB. If you experience this problem, contact TDT to request an RMA for upgrade.
