Voltage taps across integrated current-sense resistors in the amplifier outputs enable easy impedance measurements.įor microphones, either as measurement mics or as the device under test (DUT), the APx1701 is equipped with pairs of balanced and unbalanced microphone inputs. The system’s power amplifiers are configured as two independent channels, with power ratings up to 100 W for a single channel into 8 Ω. In the frequency range of 10 Hz to 20 kHz, the APx1701’s residual THD+N is ≤ -100 dB (80 kHz BW), and frequency response is ☐.08 dB (DC-coupled). With an industry-leading signal-to-noise ratio of 134 dB, the APx1701 provides 20 dB of fixed-gain amplification from DC to 100 kHz.
