transformer - audio, broadcast quality, sealed ...
DESCRIPTION
The 850NA is a broadcast quality sealed audio transformer designed for output-to-line matching or interstage coupling applications. It features a deep-drawn steel case with tin-plated finish, sealed construction with wax-potted core, and balanced split windings on both primary and secondary for circuit versatility. The transformer delivers a wide frequency response of ±0.5 dB maximum from 20 Hz to 20 kHz, with an insertion loss of approximately 1 dB and maximum power handling of +15 dBm with specified characteristics. Distortion is approximately 1.5% at 20 Hz under full power, and the unit includes an electrostatic shield between primary and secondary connected to the green lead for hum rejection. The 850NA is ideal for professional audio broadcast applications requiring impedance matching between high-impedance outputs and line-level inputs, offering stable long-term performance through its sealed, potted construction.
