ohms impedance, may be down 1 db @ 20 Khz.)
Insertion loss of apx. 1 db.
Maximum power level +15 dbm. with specified characteristics, or higher levels with
reduced low frequency performance.
Distortion is apx. 1.5% @ 20 Hz. under full power.
Electrostatic shield between pri. & sec. connected to terminal 9.
Humbucking construction
Balanced split windings on pri. & sec. for circuit versatility. Primary may be used as a
