73 APPLICATION EXAMPLE • MULTI-ROOM CONFERENCING 5 Application Example The XAP 800 can be adapted to a wide variety of teleconferencing applications, including high-end corporate boardrooms, training rooms, distance learning, and conference rooms. This chapter shows you how to set up a XAP 800 in a multi-conference room-combining system, a typical application that uses many of the XAP 800’s powerful features.
74 APPLICATION EXAMPLE • MULTI-ROOM CONFERENCING AP T H 2 Transmit ansmit Control Panel Mic 1 Mic 2 Rec eceiv eive On Off ff XAP TH2 Telephone Interface Speaker A Room A Removable room partition Mic 3 Speaker B Mic 4 Room B Control Panel Removable room partition Multi-Conference Room Room C Control Panel Speaker C Mic 5 Mic 6 The Multi-Conference Room diagram above shows three rooms with removable partitions separating the rooms.
75 APPLICATION EXAMPLE • MULTI-ROOM CONFERENCING Step 2. Configuration Click the C (Configuration Mode) button on the G-Ware toolbar to configure the matrix parameters. Establish the routing (including cross point), input, output, Expansion Bus, and processing bus settings. Set the echo canceller reference points as needed for mic inputs. See G-Ware Matrix on page 34 for more information. Step 3.
76 APPLICATION EXAMPLE • MULTI-ROOM CONFERENCING P1 Rec eceiv eive On Off ff Room A P2 S2 ✍ P1, P2, etc. represent presets established for each room in the system. S1 and S2 represent switches 1 and 2 for the wall partitions.
77 APPLICATION EXAMPLE • MULTI-ROOM CONFERENCING because the first partition is still closed. Switch 2, which would be used for Removable Partition 2, would be controlled through Pin 3. In this case, it would be set to High because the partition is closed. Room B uses Microphones 3 and 4, as well as Speaker 2. Set the appropriate routing parameters in the Preset configuration matrix. Continue configuring Preset 2 by establishing the Change Preset Label, Gating Controls, etc.
78 APPLICATION EXAMPLE • MULTI-ROOM CONFERENCING When Rooms A and B are combined, you will want to gate off the mics in either Room A or B, and route one or both of the other two mics to Speakers 1 and 2. Make the appropriate routing and gating changes in the Preset Configuration matrix to do this. Note that Preset 3 in Room C is unaffected; an ongoing meeting in that room is not disturbed when Preset 5 is activated.
79 APPLICATION EXAMPLE • MULTI-ROOM CONFERENCING Executing Presets Through the RS-232 Serial Port You can configure presets such that one or more will remain on continuously without interruption while other presets activate and deactivate to accommodate changing room configurations. This is accomplished by tailoring the Preset Execution/Reporting command (see page 131).
80 APPLICATION EXAMPLE • MULTI-ROOM CONFERENCING Therefore, you would establish the arguments for Configuration 1 as follows: #50 Preset 1 1 #50 Preset 4 0 #50 Preset 2 1 #50 Preset 5 0 #50 Preset 3 1 #50 Preset 6 0 For Configuration 2, you would establish the arguments as follows: #50 Preset 1 1 #50 Preset 4 1 #50 Preset 2 0 #50 Preset 5 0 #50 Preset 3 0 #50 Preset 6 0 For Configuration 3, you would establish the arguments as follows: #50 Preset 1 0 #50 Preset 4 0 #50 Preset 2 0 #50 Preset 5 1 #50 Preset

141 GLOSSARY G lossary Glossary Acoustic Echo Cancellation (AEC) A process in which acoustical echo is removed from a signal. AEC can be used to remove unwanted signals from mic audio if the unwanted acoustic signal is available separately as an electronic signal. Adaptive Ambient This portion of the mixer monitors the varying ambient noise level in the room and changes the threshold level at which a microphone gates on.
142 GLOSSARY Audio Processor A device that modifies an audio signal in response to certain requirements. Automatic Gain Control (AGC) Automatically increases or decreases audio gain to maintain a consistent audio level. Automatic Gating Automatically gates microphones on or off based on input levels and other parameters programmed into the XAP 800. Bandwidth The difference between the lower and upper 3dB end points of an audio band.
GLOSSARY Crossover, Linkwitz-Riley A fourth-order crossover consisting of a cascaded second-order Butterworth low-pass filter. Offers a vast improvement over the Butterworth crossover and is the de facto standard for professional audio active crossovers. Decay Rate (slow, medium, fast) Programs how quickly the audio level is attenuated once a channel has been gated off. Distributed Echo Cancellation Gentner’s proprietary system for applying echo cancellation individually to each mic input.
144 GLOSSARY gain or loss below the corner frequency is adjustable to +/- 15dB. First Mic Priority Increases the audio level required to gate on additional microphones after the first mic is on. This helps ensure that only one mic gates on when a person speaks. Gain The amount a signal is increased over a given reference, typically 0. Normally specified in dB (decibels). On the XAP 800, gain is adjustable from -65 to 20dB (85dB range) in .5dB increments.
GLOSSARY Microphone Activation A condition in which a microphone is gated on. Microphone Mixing A situation in which audio from mics on different signal lines are mixed together. All mic signals can be mixed to one signal line, any or all outputs, or mixed into separate groups. Mic signals can also be processed together or individually. Microphone 1 Mode Reverts mic assignment to a designated mic when all mics gate off. Mute A condition in which an audio signal is attenuated below the audible threshold.
146 GLOSSARY Preset One of 32 configurable memories in the XAP 800. A preset can be programmed with a variety of routing, level, gating, delay, filter, and equalizer settings to meet specific application requirements. Preset Mask Defines whether a contact closure activates on a low or high signal on the rear panel of the unit. Q Quality factor. It is the ratio of the center frequency divided by the bandwidth.
