AP - The Recognized Standard In Audio Test

APx58x Series Audio AnalyzersHOME/PRODUCTS/APx SERIES/APx58x Series


8- and 16-Channel Modular
Audio Analyzers

Channel count meets broad range of digital I/O for
simultaneous, multi-channel audio test.

APx586

The APx585 is a true multichannel audio analyzer, with 8 simultaneous analog outputs and inputs. It is ideal for designing and testing consumer devices such as home theatre receivers or pro devices such as mixing consoles. The APx586 adds a second input module for 16 simulaneous analog channels in.

The APx582 offers the same 8 channels of analog input as the APx585 in combination with 2 channels of analog output. The APx582 includes the AG52 option for perfect square waves.

All models have 216k digital inputs and outputs via AES/EBU, TOSLINK and SPDIF. Additionally, I/O may be expanded with optional Digital Serial, HDMI with ARC, PDM and Bluetooth modules.

No other audio analyzer is faster or easier to use for multichannel audio.

  • Super fast testing of a wide range of multichannel devices
  • Measure one-to-many or many-to-one crosstalk & phase across all channels
  • Measure maximum power across all channels over time
  • Supports switchers for 192 maximum channel capacity

Multichannel audio requires multichannel analysis

A true multichannel analyzer allows not just faster testing, but also a complete picture of the performance of all of a device’s input and output channels simultaneously.

Today, the majority of A/V receivers, disc players, TVs, PCs and automotive audio devices have more than two channels, from six channels (5.1) in surround sound applications to 16 or more channels in many cars. The conventional solution for testing multiple channels with a two channel analyzer has been to use switchers.

Such an approach has two major problems. First, even when automated, switching between channels is slow. Second, because only one or two channels are being observed at a time, designers and manufacturers are often blind to interactions between channels. Problems which may go unobserved include output sag in channels during full power output tests as well as phase and crosstalk interactions, particularly the combinatorial complexity of all the output channels interacting with each other.

 


What others are saying

“AP has burst onto the scene with the easiest Audio Analyzer to use but they took it up a notch by also making it the most powerful. I’ve got my cake and I am eating it too!”
