The WA301 is a DC to 1MHz amplifier with a maximum output (e.m.f.) of 30V peak to peak from a 50Ω source impedance. A 600Ω output is also provided.

The unit can provide up to 15V peak to peak into a 50Ω load and can drive up to 300mA peak into a low impedance or short circuit.

Fully variable gain between x1 and x10 is provided by a rotary vernier with calibrated end stops. A -20dB output attenuator is also incorporated.

An output clip LED is provided to warn if the output amplitude exceeds ±15V.
