AUDIO PRECISION APx1701
With an industry-leading signal-to-noise ratio of 134 dB, the Audio Precision APx1701 provides 20 dB of fixed-gain amplification from DC to 100 kHz. In the frequency range of 10 Hz to 20 kHz, the APx1701's residual THD+N is ‰¤ -106 dB (80 kHz BW), and frequency response is ±0.08 dB (DC-coupled). 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. Voltage taps across integrated current-sense resistors in the amplifier outputs enable easy impedance measurements.
For 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 balanced inputs include switchable +48 V phantom power, while the unbalanced inputs support switchable CCP (Constant Cur Power) and are TEDS-capable (Transducer Electronic Data Sheet).
The increasing complexity of audio devices (wireless Bluetooth ™ speakers or active noise-canceling headphones, for example) is driving ever-more complicated test scenarios, especially if engineers have to repeatedly switch measurement instruments. As an electro-acoustic test accessory, the APx1701 is directly integrated with APx500 audio measurement software and, when paired with any APx500 Series analyzer, provides an integrated platform capable of evaluating the performance of electro-acoustic devices as well as their analog and digital components.
