Measurement Functions
Channel Transparency Check
The DR2 tests whether a transmission channel is transparent for nonlinear PCM signals and indicates if Dolby E, Dolby Digital and/or DTS bit streams can pass. This test is also suitable for any digital audio recording device.

Channel Delay Measurement
The propagation delay between any DR2 digital audio output and the XLR sync input (which accepts AES3 signals) may be measured and displayed in seconds or video frames.
