Receiver
The SHS1890 allows the use of a wide variety of
receiver styles. In addition to the characteristics
listed in the table below, each receiver has the
following features:
Acoustic limiter: Solid-state limiting device across the
receiver transducer
Frequency range: 300 to 3300 Hz
Distortion: < 5%
Unless otherwise specified, all specifications are nominal, and
assume a 50 ohm resistive load with a bias of 4.8 V dc through
226.5 ohms, and an input of 94 db SPL at 1000 Hz into an
attached headset top. Specifications are subject to change.
