The Brownlee Precision Model 410 is a four-channel general purpose
laboratory amplifier. It can be used to amplify small signals from
signal sources which may have a large common-mode level and high frequency
noise. Each channel consists of a high gain/low noise amplifier, an
input coupling selector, a 2-pole lowpass filter, and an output offset
control. A control knob sets the amplifier parameters and the values
are displayed on a bright LED alphanumeric readout.
