GS3015 - HYB DATA SHEET
DESCRIPTION
The GS3015 incorporates Gennum's GL504 preamp, three of
the required capacitors and a mid supply referencing 48K
resistor. All that is required for a fully functional hearing aid
system is the addition of a microphone, receiver, volume
control, interstage coupling capacitor and an MPO adjusting
potentiometer.
The GS3015 has been designed to mount on the back of the
Microtronics PJ88S Socket Volume Control. This translates to
a saving in space within the hearing instrument, as the circuitry
mounts directly beneath the volume control. If the VC requires
replacing, it is a simple procedure to remove the defective unit
from the socket and install a new device. This does not disturb
the electronic circuitry.
The major advantage of the GL504 over other preamplifiers is
the electronic MPO adjustment. Since conventional MPO is not
possible in a class D receiver, Gennum provides it in the
preamp.
