User manual RANE ECS

[. . . ] RANEWARE OPERATORS MANUAL ECS ENGINEERED CONFERENCE SYSTEMS ECS RaneWare Manual This manual contains information on RaneWare software installation and ECS controls, device control language, system setup, applications and operation. All software controls are printed here in sans-serif type to help distinguish between hardware and software. Consult the ECS Hardware Manual for the ECB 62e Base and ECM 82e Mixer installation options, audio and data connections, control and indicator descriptions, and audio specifications. This manual first begins with RaneWare installation, then describes all software controls, and those particular to ECS. [. . . ] Only then will the chairman's Mic Gate Off due to the sneezer's Mic becoming the Master Mic. (Cool stuff. ) Master Mic is also extremely useful in video-follows-audio applications when you need to move the Program Signal Offset signal flow camera position to follow "who" is talking. The Master Mic Delay timer can be adjusted to times beyond the time required to reply "yes, " or to cough, or shuffle papers. This avoids the problem of the camera switching over to someone who is blowing their schnoz. With the room controller, query the ECB 62e for the Master Mic OPSTAT parameter to switch to the correct camera position. Port Sig Release Once audio is no longer detected at any Port Input, the Port indicator shuts off after the Port Signal Release time has elapsed. This timer is useful in multipoint videoconferencing when you wish to switch the video back to a default video location/picture after conversation pauses. Mic Sig Release Once audio is no longer detected at any Mic, the Mic indicator shuts off after the Mic Signal Release time has elapsed. This timer is useful in video-follows-audio applications when you wish to switch the camera back to a default location after conversation pauses. The Mic Signal Release also affects the time between when people stop talking and when the various Gates (Mixer Gate, Noise Gate, Mic Gates, Mixer Suppression and Port 1 Suppression) turn on or off. Adjusting the Mic Signal Release time can help the psychological timing and comfort for talkers. Typical default value: 0. 35 seconds or more. RW Manual-11 Prog Sig Release One can think of this parameter as either the longest distance or delay time between a speaker and a Mic in the room, or think of Program Signal Release as the room reverb time (sort of) -- although, extremely few conference rooms are statistically reverberant spaces. Since you don't want Mics to Gate On due to loudspeaker audio, the Program Signal Release time is adjustable to allow the loudspeaker audio to decay in the room before ECS releases the Program Status indicator. Near Sig Offset This helps prevent a single talker from Gating mulitple Mics. The first Mic that Gates On (audio detected above the Mic Threshold) illuminates the Mic Signal indicator. This causes the Near Signal Offset value to be added to all other Mics' Threshold Levels. For example, when the chairman talks, his Mic Gates On causing a Mic status signal. Immediately, the Threshold Level of all Mics except the chairman Mic is adjusted by the Near Signal Offset. Thus, if the other Mics are set to a Threshold Level of -25 dB, when the chairman talks, all other Mics' Threshold Levels are forced to -5 dB (-25 plus 20). This helps prevent Mics that are near the chairman's Mic from Gating On. This improves the signal-to-noise and improves Echo Canceller performance. Independently, if any Port Signal is detected, the Near Signal Offset is also added to the Threshold Level of all other Ports. [. . . ] CHNUM = $01 reprograms only the port data in working Memory from the selected preset Memory. The Input Attenuators, Threshold Levels, and Output Attenuators are not affected. CHNUM = $02 reprograms only the mic data in working Memory from the selected preset Memory. The Gate Depths, Threshold Levels and Gate Releases on all mic channels are not affected. [. . . ]
