NOTES:
* Electrostatic shield between
primary & secondary
** Single plate requires parallel feed.
When operating at impedances
below nominal, power capability is
lower and the frequency spectrum is
shifted downward, conversely, at
higher impedances power capability
and frequency spectrum will be
shifted upward.

CHASSIS MOUNT - HERMETICALLY SEALED
BROADCAST QUALITY
AUDIO TRANSFORMERS
• Deep-drawn steel case with tin plated finish, with two convenient 6-32
mounting studs with hardware (same as 800 series except low profile).
• Hermetically sealed for stable characteristics and long life. Header has nine
0.22" long solder terminals.
• Frequency response +/- 0.5 db max. from 20 Hz. to 20 Khz., except units
over 5K 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 secondary and vice versa for impedance matching.
• Overall dimensions 1.7" x 1.2" x 1.65" high max.
• Shipping weight 0.4 lb.
