  • Page 11: Menu Introduction

    3.2 Menu Introduction Most AMX-101i parameters are accessed and changed via an easy-to-use menu. The flow chart of Figure 3.2 outlines the entire AMX-101i menu path. The menu consists of 10 major functions: audio group selection, mute, level adjustments, group monitoring, channel swap, audio delay, overwrite, channel status mode, calibration, and factory reset.

    3.3 Input Status Monitoring § The 525 LED turns on to indicate a 525-line serial digital 4:2:2 signal has been detected on the 4:2:2 IN BNC. § The 625 LED turns on to indicate a 625-line serial digital 4:2:2 signal has been detected on the 4:2:2 IN BNC.

  • Page 14: Audio Group Selection

    3.5 Audio Group Selection The analog audio inputs can be embedded in any of four groups within the horizontal ancillary data space (HANC) of the 4:2:2 digital video signal. If no audio data is detected in the audio group, selected here, within the input 4:2:2 serial digital signal, then multiplexing is automatically performed.

  • Page 15: Level Adjustments

    3.7 Level Adjustments This section describes the necessary steps to take in order to adjust the analog audio input levels. Each input gain configuration L1, R1, L2 and R2 can be individually set between 0dB and 31 dB. A 0 dB setting provides a full scale output of 24 dBu.
