ET-16A (B) Headboxes
The ET-16 headboxes provide an interface between the
ES-8 amplifier and the patient electrodes. The ET-16A
and ET-16B provide 32 different electrode inputs into
the input select switches of the ES-8 amplifier. The ET-
16A input labels are 1 through 16, and the ET-16B input
labels are 17 through 32. The ET-16A and B headboxes
are only used on the ES-8 amplifier and are the only
electrode inputs available on the ES-8 amplifier.
ET-208 Headbox
The ET-208 headbox provides an interface between the
EA-4 or EA-2 amplifier and the patient electrodes. The
ET-208 headbox cannot be used with the ES-8
amplifier. The ET-208 has eight pairs of electrode
inputs and eight concentric connections that can
interface with the EA-2 or EA-4 amplifier.
