Control Room (Cubase Pro only) Control Room Mixer 361 1)Source Selectors Allow you to select the source for the Control Room channel. The available sources depend on the channels that you added to the Control Room. The signal presence indicators in the upper left corner light up when the source channel is sending data to the Control Room channel. 2)Dim Signal Activate this to lower the Control Room level by a fixed amount. This allows a quick reduction in monitor volume without disturbing the current monitor level. Clicking the DIM button again returns the monitor level to the previous setting. 3)Use Reference Level Enable this button to set the Control Room level to the reference level specified in the Preferences dialog (VST–Control Room page). The reference level is the level that is used in calibrated mixing environments, such as film dubbing stages. 4)Activate Metronome Click Activates the metronome click. 1)Monitor Selectors Allow you to select another monitor source. 2)Downmix Preset Selectors Allow you to select another downmix preset. 3)Activate Talkback Allows you to activate talkback for communication between the Control Room and the performers in the studio. Click to activate, click and hold for momentary mode. 1)Click Level and Click Pan Use the Click Level and Click Pan controls to set the volume and the pan position of the metronome click for the Control Room channel.
Control Room (Cubase Pro only) Control Room Setup 362 2)AFL/PFL Allows you to determine whether the signal of a listen-enabled channel is routed to the Control Room channel after applying the fader and pan settings (AFL) or before applying the fader and pan settings (PFL). 3)Enable Listen for Output Enables the listen bus function for the Control Room output. 4)Listen Level Allows you to adjust the volume of listen bus signals that are routed to the Control Room output. 5)Listen Dim Allows you to adjust the volume of the Main Mix when channels are in listen mode. This keeps listen-enabled channels in context with the Main Mix. If the Listen DIM level is set to the minimum value, you only hear the listen-enabled channels. 6)Talk Dim When Talkback is active, this slider controls how much the output of all the channels in the Control Room Mixer is reduced, to prevent unwanted feedback. Control Room Setup The Control Room setup contains additional settings for the channels. • To open the Control Room setup, click the Setup tab at the bottom right of the Control Room. The Control Room setup is divided into a number of sections that you open by clicking their headers.
Control Room (Cubase Pro only) Control Room Setup 363 Input Gain Setting up the input gain can be useful in the following situations:
Control Room (Cubase Pro only) Control Room Setup 364 • To balance the level of external inputs, for example, CD players and other sources to the Main Mix level, for A/B comparisons. • To balance the level of your monitor systems, so that switching between sets of speakers does not change the playback volume. Input Phase Reversing the input phase can be useful for external inputs and monitor speaker outputs. Insert Effects Each Control Room channel has a set of insert effect slots. • Use the inserts on the Control Room channel for metering and spectral analysis plug-ins. All solos including the Listen bus will come through the Control Room channel and allow analysis of individual sounds. A brickwall limiter in the last insert slot of the Control Room channel can prevent accidental overloads and damage to speaker systems. • Use the inserts for the talkback channel to control the dynamics of the talkback microphone. This helps protect performers’ hearing and ensures that everyone can be heard over the talkback microphone. • Use the monitor inserts for surround decoding or brickwall limiting to protect sensitive monitor speakers. Each monitor channel has a set of eight inserts, all of which are post Control Room fader.
Control Room (Cubase Pro only) Setting Up a Cue Mix 365 Setting Up a Cue Mix You can create a cue mix from the fader and pan levels that are used in the MixConsole and change them to meet the needs of the individual performers. PROCEDURE 1. In the MixConsole, select the channels from which you want to copy the settings. 2. In the Control Room, do one of the following: • To apply the function only to this cue channel, right-click on a cue channel to open the context menu. • To apply the function to all cue channels, click anywhere but on a cue channel to open the context menu. 3. Select From selected mixer channels and select one of the functions. Cue Mix Context Menu Change Cue Sends Levels Allows you to adjust multiple send levels at the same time. Use Current Mix Levels Allows you to copy the fader levels of the selected tracks to the cue sends. This sets all cue send levels for the selected tracks to the level of the main channel fader. It also changes the cue send status to pre-fader, so that changes in the main mix do not affect the cue sends. Use Current Pan Settings Allows you to copy pan information from the main mix to the cue sends of the selected tracks. If the cue send is mono, the pan setting is copied, but the output of the cue send is the sum of the left and right channels. Enable Cue Sends Allows you to activate the cue sends of the selected channels. To be able to hear the cue mix for a cue channel, the cue sends must be enabled. Disable Cue Sends Allows you to disable the cue sends of the selected channels.
Control Room (Cubase Pro only) Adjusting the Overall Cue Send Level 366 Reset Cue Sends Allows you to deactivate the cue sends, to change the send level of all selected channels to 0 dB, and to set the signal source to post-fader. This way, any changes to the main mix also change the cue mix. To raise the level of individual cue channels, raise the level on that channel. Adjusting the Overall Cue Send Level You can adjust multiple send levels at the same time for the cue send mix, keeping the blend intact while lowering the overall volume. This is sometimes necessary, because the levels in the main mix are often optimized for the loudest possible signal level without clipping. This means that when you create a “more me” mix, you may find that there is not enough headroom available in the cue send to raise levels without introducing clipping. PROCEDURE 1. In the MixConsole, select the channels that you want to modify. 2. In the Control Room, right-click a cue channel to open the context menu. 3. Select From selected mixer channels > Change Cue Sends Levels. 4. Activate Relative Mode. This way, you adjust the existing levels. By deactivating Relative Mode, all cue sends are set to the same absolute level. 5. Adjust the level as necessary. The level of all selected cue sends is adjusted by the set amount. 6. Click OK.
367 Metering Loudness Cubase allows you to measure the loudness in compliance with the loudness recommendation R 128 of the European Broadcasting Union (EBU). Measurements that correspond to this recommendation consider loudness, loudness range, and maximum true peak level values. Loudness Measurement The following measurements are performed: •Integrated Loudness Average loudness that is measured over the whole track in LUFS (Loudness Unit, referenced to Full Scale). According to the loudness recommendation R 128, audio should be normalized at -23 LUFS (±1 LU). •Short-Term Loudness Loudness that is measured every second on an audio block of 3 seconds. This gives information about the loudest audio passages. •Momentary Loudness Maximum value of all momentary loudness values that are measured every 100 ms in an audio range of 400 ms. Loudness Range The loudness range measures the dynamic range over the whole title in LU (Loudness Units). It reports the ratio between the loudest and the quietest non-silent sections. The audio is divided into small blocks. Every second there is one audio block, and each block lasts 3 seconds so that the analyzed blocks overlap. The top 10 % of the quiet blocks and the top 5 % of the loud blocks are excluded from the final analysis. The calculated loudness range is the ratio between the loudest and quietest remaining audio blocks. This measurement helps you to decide if and how much compression or expansion you can or should apply to the audio.
Metering Loudness 368 True Peaks When a digital signal is converted to an analog signal, EBU R 128 recommends that you rather measure an estimation of the real peaks instead of relying on digital peaks. This avoids clipping and distortion. Naming and Units The EBU R 128 proposes the following naming and units conventions: • A relative measurement, such as a value that is relative to a reference level, LU as Loudness Unit (1 LU is 1 dB). • An absolute measurement, LUFS as loudness unit referenced to full scale. 1 LUFS can be understood as 1 dB in the AES-17 scaling. Loudness Meter The Loudness meter allows you to analyze, measure, and monitor the loudness of your project in real-time during playback or mixing. • To open the Loudness Meter, select Devices > Control Room Mixer > Meter > Loudness. • The green triangle on the left side shows the integrated loudness value. • The gray triangle on the right side shows the short-term loudness.
Metering Loudness 369 The following parameters are available: 1)Measure Loudness Allows you to activate the loudness measurement. 2)Switch between LU and LUFS Allows you to switch the meter scale between LU (relative values) and LUFS (absolute values). 3)Configure Loudness Settings Opens a dialog with further loudness settings. 4)Reset Loudness Allows you to reset the loudness measurement. 5)Momentary Max. Shows the maximum of all measured momentary loudness values. 6)Short-Term Shows the loudness that is measured over a duration of 3 s. 7)Integrated Shows the average loudness that is measured from start to stop. The period of measurement is shown in the Time display. The recommended value for the integrated loudness is -23 LUFS. This absolute value is the reference point for the relative LU scale where -23 LUFS equals 0 LU. 8)Range Shows the dynamic range of the audio that is measured from start to stop. This value helps you to decide how much dynamic compression you can apply. The range that is recommended for highly dynamic audio like film music, for example, is 20 LU.
Metering Loudness 370 9)True Peak Shows the true peak level of the audio. The maximum permitted true peak level in production is -1 dB. 10)Time Shows the duration of the integrated loudness measurement. Loudness Settings • To open the Loudness Settings dialog, select Devices > Control Room Mixer > Meter > Loudness > Configure Loudness Settings. The following parameters are available: 1)Select Preset Allows you to create, load, and remove loudness presets. 2)Momentary Max. Allows you to specify a reference value and a tolerance value for the maximum momentary loudness. If higher values are detected, the clipping indicator in the loudness meter turns red. 3)Short-Term Allows you to specify a reference value and a tolerance value for the short-term loudness. If higher values are detected, the clipping indicator in the loudness meter turns red. 4)Integrated Allows you to specify a reference value and a tolerance value for the integrated loudness. If higher values are detected, the clipping indicator in the loudness meter turns red.
