APx58xB Series Multichannel Audio Analyzer
The Audio Precision APx58xB Series is a true multichannel audio analyzer, with eight simultaneous analog outputs and inputs. It is ideal for designing and testing consumer devices such as home theater receivers or pro devices like mixing consoles.
The APx582B offers the same eight channels of analog input as the APx585B in combination with two channels of analog output, and includes the AG52 option. The APx586B adds a second input module for 16 simultaneous analog input channels. All three models support one-to-many or many-to-one crosstalk and phase measurements across channels, maximum power across all channels over time, and switchers for up to 192 channels.
Key Features
- APx582B: 2 analog outputs / 8 inputs; APx585B: 8 / 8; APx586B: 8 / 16
- Residual THD+N −103 dB + 1.4 µV (20 kHz BW)
- Simultaneous multichannel crosstalk, phase and maximum power measurements
- Up to 192 channels with switchers
- AES/EBU, TOSLINK and S/PDIF digital I/O; Dolby / DTS encoded file generation
- Optional Bluetooth, PDM, Digital Serial, HDMI and AMC modules
