DESCRIPTION
The hybrid consists of an LS509 amplifier, four capacitors, and two selectable bias resistors. The values of the capacitors assure proper operation of the circuit for the most commonly required frequency responses.

FEATURES
• Gennum’s LS509 3 stage amplifier
• independent preamp can be used as telecoil preamplifier
• four “must use” capacitors mounted on hybrid
• choice of 3 resistors to set transducer current
• easy assembly and high reliability
