CHAPTER 3: System Configuration ClearOne’s G-Ware software provides an easy interface for configuring and controlling your PSR1212. While some configuration can be done using the front panel LCD menus, G-Ware is required to complete the custom configuration of your audio conferencing system. If you are using the default settings, no configuration is necessary. This chapter describes how to install G-Ware and create a site. It also describes all configurable parameters of your system.
22 System Configuration ~ Installing G-Ware Creating Floppy Disk Copies Depending upon the computer equipment you have available, you might need to install G-Ware software from floppy disks rather than the included CD. To do this, a Disk Copy program is provided in G-Ware that allows you to transfer G-Ware to floppy disks. You will need a PC with a CD-ROM drive to make the transfer.
23 System Configuration ~ Site Setup Site Setup Creating a new site New site files are created through the Site Properties window in G-Ware. A site file contains all information about a particular installation including all unit settings and properties. It also provides G-Ware with the necessary information to communicate ✍ Whenever a mouse click is indicated in this manual, it refers to the left mouse button unless otherwise stated. with the site hardware using your PC.
24 System Configuration ~ Site Setup Adding a PSR1212 You can add a PSR1212(s) to your site file by connecting to your site and using G-Ware to automatically create icons for the detected units.

Note that the configurable filter parameters displayed depend on the selected filter type. 2. Click Add Filter to add a filter to the graph or table. 3. Configure filter parameters using the previously described lists.
36 System Configuration ~ Inputs and Outputs Chairman Override Chairman Override provides gating priority for this mic input over any other mic input within the same gating control (mixer) groups. When a mic with Chairman Override enabled gates on, all mics which don’t have Chairman Override enabled will gate off. Default is off. Adaptive Ambient Adaptive Ambient adjusts the ambient reference level as noise and room conditions change.
System Configuration ~ Inputs and Outputs Figure 3.29. PSR1212 automixing gate functions Ambient Level if you want to specify a fixed reference point rather than one that adjusts for background noise. The range is from -80 to 0dB. Default is Off. Decay Rate Decay Rate determines how fast a channel gates off after the hold time expires. Default is Medium. PA Adapt and AEC Reference When using the PA Adaptive mode, the output that carries this information, i.e. the reference output, must be defined.
38 System Configuration ~ Inputs and Outputs If you select a virtual reference, the Virtual Reference window will open. You can also open this window from the G-Ware toolbar. Figure 3.31. Virtual Reference toolbar button Figure 3.32. Virtual Reference window. Use this window to select which signals will be included in each of the four Virtual Reference points. The routing matrix portion of this window cannot be edited. Virtual references are used when you need to reference multiple outputs.
39 System Configuration ~ Inputs and Outputs Gating Group Select In addition to specifying gating characteristics for each mic input, you can assign the inputs to a gating group for greater flexibility and control. When inputs are assigned to a gating group, the gating information from the inputs is used to Figure 3.33. Gating Group Select pane control how the entire mixer behaves.
40 System Configuration ~ Inputs and Outputs 3. Leave 1st Mic Priority selected (default) to enable this feature; otherwise, clear the selection to disable it. ClearOne recommends leaving this setting on. This setting helps maintain maximum audio intelligibility by allowing only one mic to gate on to a participant’s voice. 1st Mic Priority allows more than one microphone to be activated at the same time—it simply restricts mics from gating on to the same audio source.
41 System Configuration ~ Inputs and Outputs Optimizing input gain structure How you adjust an input’s gain directly affects sound quality. The optimal input gain setting is one which is adjusted as high as possible above the noise floor without introducing clipping. Clipping can cause distortion which can damage amplifiers and loudspeakers. To adjust the input level properly, place a signal on the input at the maximum level it will generate.
42 System Configuration ~ Inputs and Outputs Inputs 9–12 The PSR1212 supports four line level only inputs for auxiliary audio sources such as VCRs and CD players. To open the Inputs 9–12 configuration window, click the Inputs 9–12 button on the Flow Screen. The In 9–12 button on the Matrix Screen will also open this window. These non-gated inputs are balanced. The nominal input level is 0dBu. Figure 3.38. Inputs 9–12 Configuration window To select an input channel, click a blank area in the input pane.
43 System Configuration ~ Inputs and Outputs Gain The Gain slider on the selected input in the Inputs 9–12 window is used to adjust input volume level. • Max adjust Use the Gain slider to adjust input volume level. You can also enter the level directly in the decibel box below the gain scale. Min adjust Min/Max limits Use the yellow and blue upper and lower limit arrows on the Gain scale to create Figure 3.39. Gain adjust on line level input minimum and maximum gain level limits.
44 System Configuration ~ Inputs and Outputs Outputs 1–12 The PSR1212 has 12 line level outputs for sending audio to recorders or amplifiers. To open the Outputs 1–12 configuration window, click the Outputs 1–12 button on the Flow Screen. The Outputs 1–12 button on the Matrix Screen will also open this window. Figure 3.41. Outputs 1-12 configuration window These line level outputs are balanced. The nominal output level is 0dBu. The outputs can adjust from -65 to 20dBu.
45 System Configuration ~ Inputs and Outputs passing NOM information. Enable NOM if you want to place this output in a constant gain mode. Default is on. When enabled, the NOM button light illuminates green. Gain The Gain slider on the selected output in the Outputs 1–12 window is used to adjust output gain level. • Use the Gain slider to adjust output volume level. You can also enter the level Max adjust Min adjust directly in the decibel box.
46 System Configuration ~ Expansion Buses Expansion Buses Routing of audio to the expansion buses is done in the Matrix Screen. See page 30. For information on setting up an expansion bus network, see page 11. ✍ From Expansion Bus O–Z Click the From Expansion Bus O–Z button on the Flow Screen to open the From Expansion Bus Labels window. You can also access this window from the Matrix Screen. Figure 3.43.
47 System Configuration ~ Processing Processing Processing A–H There are eight processing blocks in the PSR1212, each with filters, compressors, and delay to provide pinpoint audio configurations. To open the Processing configuration window, click the Processing A–H button on the Flow Screen. The To and From Processing buttons on the Matrix Screen will also open this window. Figure 3.45. Processing window To select a processing block, click a blank area in the Process pane.
48 System Configuration ~ Processing Cmprs (compressor) Cmprs opens the Compressor Setup window (see Figure 3.46). With the compressor you can change the gain transfer characteristics of the signal path and control the dynamics of a signal. When the signal exceeds the threshold level, gain reduction occurs at the rate specified by the reduction ratio. The attack time determines how aggressively the compressor reacts to increases in level.
System Configuration ~ Processing Post Compressor Gain Adjust the compressor gain with the gain slider or by using the ▲ and ▼ buttons. The graph reflects the input/output decibel levels with the gain setting you select. Threshold Threshold determines the RMS level at which the compressor begins to operate. The range is from -30 to +20dBu. Default is 0dBu. Ratio Ratio changes the rate of compression applied to the input signal as the signal exceeds the threshold level. The range is 1:1 to 1:20.
50 System Configuration ~ Processing The frequency response and phase vs frequency of the total transfer function of all filters is displayed in the window. Each filter can be disabled without affecting the filter settings. All filters can also be disabled using a single command. By default, they are not enabled and the filter types are not defined. Below is a description of each feature in the window. Active Filter The Active Filter displays the filter that is applied to the processing channel.
51 System Configuration ~ Processing Figure 3.48. Low/Mid/High Loudspeaker Driver configuration Refer to the figure above. Note that as you create filters across several processing channels, you can observe their crossover points and general shape of the frequency response. In this case, several Linkwitz-Riley filters are being created across three processing channels to establish a balanced frequency response from low-frequency, midrange, and high-frequency transducers.
52 System Configuration ~ Processing Introducing an appropriate amount of delay to the forward-mounted driver(s) re-establishes the acoustical alignment necessary for proper sound imaging in a room. The same principle of introducing delay applies to separate speaker enclosures located various distances from the listening area. Other types of delay to consider when establishing delay parameters are delays which occur naturally as a result of processing operations within the PSR1212.
CHAPTER 4: Advanced Configuration Presets Overview For many audio conferencing applications, a great deal of system flexibility is needed to meet the challenges presented by changing meeting or conference room requirements. These requirements might include changes in muting, audio sources, room orientation, or room combining. And ideally, these changes are made instantaneously—without interrupting or affecting any meetings in progress.
54 Advanced Configuration ~ Presets G-Ware Toolbar G-Ware Menus Preset Configuration Pane Preset Matrix Screen Status Bar Figure 4.2. Preset Mode Matrix Screen The Matrix Screen in the Preset Mode is very similar to the Matrix Screen in Configuration Mode. All Input, Output, and Processing windows can be accessed by clicking on their respective buttons. You can also create custom labels by clicking on the current labels. The routing matrix is grayed out because no routing changes have been made.
55 Advanced Configuration ~ Presets Preset Description. Use the Preset Description box for entering information about the preset. This description is stored in the site file, not the unit. Preset Mask Control/Status B. With Preset Mask Control Status B you can require an active high (H) or active low (L) contact on a control pin (1–19 odd numbers) or combination of several contacts in order to run the preset. A typical use for Preset Mask Control Status B is a room combining Figure 4.4.
56 Advanced Configuration ~ Presets Virtual Reference. The Virtual Reference button opens the preset Virtual Reference window. Using the Virtual Reference window, you can select which signals will be used by the four Virtual Reference points in this preset configuration. The only input rows which will be shown in this window are the input rows which are active in the Preset Matrix Screen. The routing matrix (right pane) in this window is read-only.
Advanced Configuration ~ Presets To create a preset 1. From the Preset Selection list, select the number of the preset you will be configuring. Enter a description of the preset in the Preset Description box. 2. If you want to password protect this preset, click Protected. See page 26 for information on creating the preset password. 3. 4. Configure the routing matrix and make cross point attenuation adjustments. Configure input, output, and processing channel settings as needed.
58 Advanced Configuration ~ Presets Running presets Presets can be run from G-Ware or the front panel controls on the PSR1212. You can also program external control devices (such as AMX or Crestron, ClearOne Control Panels, XAP IR Remote, and GPIO devices) or use macros to run presets. See Chapter 6: Control for more information on creating custom control. To run a preset using G-Ware Figure 4.7. Execute Preset toolbar button 1. Select the Execute Preset button on the G-Ware toolbar. 2.
59 Advanced Configuration ~ Presets Figure 4.9. Assigning a state to a preset command in the Macro Editor If a preset is flagged as “On,” nothing will happen when the preset is executed again because the system knows it has already been run. This prevents any manual adjustments that are made during the course of the meeting (gain, muting, etc.) from being lost. Room combining example In the room combining scenario depicted in Figure 4.
60 Advanced Configuration ~ Presets The four macros (one for each configuration) are set up as follows: 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 When the room is in Configuration 1, running the Configuration 2 macro will change the presets to the following states: • P1 does not change because the flag is already set (1) • P2 and P3 clear their states (0) so they can be run • P4 runs and sets its state to on (1) which prevents other presets from rerunning it • P5 and P6 clear their states
61 Advanced Configuration ~ Macros Macros A macro is a series of commands which can be run from G-Ware, the front panel controls, or by using any external control device. Macros streamline the operation of the PSR1212, allowing you to make quick configuration changes and, as previously discussed, making it possible to execute multiple presets simultaneously (see pages 58–60). Macros can also contain commands that are executed on other XAP units.

Glossary Glossary 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. Ambient Level The manually-set background noise level upon which the PSR1212 bases gating protocols. Used only if the Adaptive Ambient feature isn’t used. Ambient Noise The existing room-level noise, such as that caused by ventilation systems, paper shuffling, and background chatter.
Glossary 128 Clipping A condition in which a signal level exceeds the maximum level a circuit can handle. This is usually caused by improper gating parameters and gain settings. It causes distortion and typically leads to listener fatigue and accelerated failure of loudspeaker drivers. Compression An induced reduction in the dynamic range of part or all of an audio signal. Compression is usually used to protect individual loudspeaker components from the damaging effects of transients.
Glossary Decay Rate (slow, medium, fast) Determines how fast a channel gates off after hold time expires. Default is medium. Default meter The input/output displayed on the front panel LED meter when a input/output meter is not specifically selected elsewhere. Delay A setting in the Processing window. Delay calculates the amount of signal delay (up to 500ms) based on the distance between audio source and audience and the temperature.
130 Glossary the designated frequency occurs at a fixed 6dB/octave rate. The gain or loss below the corner frequency is adjustable to +/- 15dB. Filter Display A group of nodes plotted on a logarithmic scale. The PSR1212’s filter display can be accessed through the Inputs 1-8, From Processing, or To Processing windows. 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.
Glossary GPIO (general purpose input/output) The Control/Status A and B ports on the PSR1212 unit. The GPIO Builder is used to program Control/Status A pins. G-Ware Software The PSR1212’s setup and configuration software. Hold Time The length of time that a microphone remains on after the voice (input) level drops below the gate ratio. This can be used to prevent the microphone from gating off during brief pauses in speech. Last Mic Mode Sets the last-activated mic to Last On, Mic 1-8, or Off.
132 Glossary Mixer mode The mixer mode has two settings: master and slave. Mixer mode can be configured from the front panel or in the Unit Properties window. Mute A condition in which an audio signal is attenuated below the audible threshold. Number of Open Mics (NOM)/Constant Gain Mode Adjusts the output level based on the number of mics gated on and routed to an output. O–R buses These four audio buses communicate NOM count and mic mixing parameters.
Glossary • Preset The preset password is created in the Unit Properties window and makes it possible to lock certain presets. A locked preset can be executed without the password. However, a password must be entered to edit the preset. • Site file (File Access) The site file password is set in the Site Properties window and will lock the site file. Users must enter the password in order to open the site file. Phantom Power Power supplied by the PSR1212 to power most condenser microphones.
134 Glossary S–Z buses These eight buses are defaulted as auxiliary mix buses. They are used to route auxiliary audio to and from other units on the network. These buses are also used as mic mix buses when NOM count is not required. Serial Command A bit description designed to execute an instruction or command. Serial mode The serial mode determines the format in which serial commands return—text or binary. The mode defaults to Binary when G-Ware is connected and to Text when disconnected.
Glossary you to reference multiple signals without sacrificing an analog output. You can open the Virtual Reference window from the G-Ware toolbar or from the Acoustic Echo Cancellation window. White Noise Acoustical noise with equal energy throughout a given frequency range.
