The full DLC User Manual describes the standard DLC as supplied with the stand-alone Dolby Lake Processor (DLP). Note that the Dolby Lake processing system integrated in the Lab.gruppen PLM Series has slightly different functionality from the stand- alone DLP. In addition, numerous features specific to the PLM Series are accessible only by the DLC PLM Edition software.
2 2.1 introduction Thank you for choosing the Lab.gruppen PLM Series of Powered Loudspeaker Management systems for your sound reinforcement needs. We are confident that you will be pleased with the performance, unique features, configuration flexibility, reliability, and long- term durability offered by PLM Series products.
3 soFtware installation To complete the installation options here, you may also need to refer to the Dolby Lake Controller User Manual , chapter 2, for comprehensive instructions on: ▸ Configuring your Tablet PC for working with the Dolby Lake Controller PLM Edition software ▸...
▸ On initiating the install procedure itself, the Installation Wizard launches. At Step 4 (Installation Folder selection), a different destination location (pathname) from that containing the existing software must be specified. ▸ At Step 5 (Shortcut folder), enter a different Shortcut name for the start menu folder from that which is already in use.
8 Dolby Lake Controller User Manual PLM Edition Addendum 4.3 Loadsmart LoadSmart is Lab.gruppen’s exclusive system for verifying the load connected to each output channel of the PLM. LoadSmart is set up and run from the Load tab.
▸ An alternative method is from Main page button bar menu. Tap the Modules button, select a Module, and then tap the I/O Config button. The I/O Config page opens; tap the Lab.gruppen info button (F7). ▸ Amplifier Module View is also accessed by tapping one of the Module icons on the All tab.
5 operation 5.2 status Tab The Status display is selected by tapping the Status tab in Amplifier Module View. A horizontal set of “channel strips” displays data relating to each power output section assigned to the selected Module. Figure 5.2: Status tab showing speaker and power output channel status 10 Dolby Lake Controller User Manual PLM Edition Addendum The channels are presented in Module output order (e.g.
5.2.1 attenuation The virtual fader permits adjustment of the channel’s attenuation, from 0 dB (fader fully open) to - ∞dB (fader closed). Moving this fader has the same effect as adjusting attenuation on the PLM front panel in Menu Mode, at Menu > Attenuation . The attenuation value may also be set by tapping the numeric display at the top of the fader.
This field confirms the name of the PLM unit and the channel number. (The frame name is assigned in Modules >Label & Lock > Label Frame. This name also displays in Frame block, line 2, on the PLM front panel display.) The channel number corresponds to the power output channel.
Entering a value in the ALL cell applies that value to all power output channels. Amplifier Gain may also be set via the PLM front panel at MENU > MODULE > AMP GAIN. 5.3.3 inter-sample Voltage peak Limiter (isVpL) The table’s second row shows the ISVPL threshold as currently set.
5 operation 5.3.4 amplifier Clip Level From the Amplifier Gain and ISVPL values, the Amplifier Clip level is calculated, and displayed in the third row of the table for each channel. This figure represents the digital signal level from the Module output which will produce clipping or limiting at the power output channel.
the selected amplifier output channel in the upper table. The values for a specific cable’s properties (resistivity, gauge, etc.) can be obtained from the cable manufacturer’s data sheets. 5.4.3 ambient Temperature The load verification and monitoring system takes ambient temperature into account when checking the performance of the load.
5 operation 5.4.6 Loadsmart results The Load Results page reports the findings of the verification procedure and and also contains the function controls for SpeakerSafe. Results for each of the PLM power outputs are displayed together with a summary in the ‘All’ column. 5.4.6.1 Load Type verification The results shown in the Load type row of the table will be one of the following:...
through for SpeakerSafe to monitor by selecting the “Force to configured” button. 5.4.6.3 Voice Coil Temperature The third row of the Load Results table displays the estimated loudspeaker voice coil temperature from the LoadSmart test results. This is calculated from the LoadSmart verification results and Fingerprint data.
▸ frame psU temp of the PLM PSU relative to its maximum safe level. ▸ amp channel temp the PLM power output channel devices relative to their maximum safe level. ▸ speaker magnet temp computed temperature of the loudspeaker magnet/s for each channel.
▸ – Shows the PLM channel’s amp output current output current relative to its maximum safe value. (This is the value at which the CPL becomes active.) ▸ amp output voltage – Shows the power output channel’s voltage relative to the voltage permissible, regardless of ISVPL setting.
5 operation 5.6 Events Tab The Module Events tab lists all faults and warnings occurring in the power output channels allocated to the selected Module. The Event Log displayed here is the same as that displayed in the Global Events tab. However, here events are filtered to show only those relevant to the currently selected Module, power output channels assigned to that Module, and the Frame(s)
Amplifier Global View. Amplifier Global View is accessed from the All tab. Tap the Amplifier Menu button (F9), then tap the Lab.gruppen info button in the button bar (F8). 5.7.1 Global power Control These two buttons (On and Standby) control the power status of all PLM Frames within the system that are active in the DLC PLM Edition software’s work area.
5 operation 5.8 Global Events Tab This is the other tab available in Amplifier Global View. It provides an Event Log which lists all warnings, faults, and user actions that have occurred in all devices on the network since the DLC started. In addition, it will contain the events that can be read from each PLM’s internal log covering the 4 hours prior to starting the DLC PLM Edition software.
▸ – Displays the system time (and date) start time at which the event occurred ▸ Duration – This column displays the legend ACTIVE while the fault/warning is active. Once the fault/warning becomes inactive, the time period (duration) for which it was active is displayed.
