BRUEL & KJAER 2619 - Frequency Characteristics; Gain; Distortion

2.4 FREQUENCY CHARACTERISTICS
The frequency characteristics of the preampl ifier with 1/2" and 1" micro-
phones are shown
in · Fig.2.4. The low frequency response depends on the
capacity connected across its input. Typical curves are shown in Fig.2.5.
