1 – Introduction The IF-SM/DM card allows the connection of one or two surround monitoring systems. It provides flexible setup capabilities, routing, downmix capabilities, bass management, and monitor setup, etc. from within the IF-SM/DM’s interface. Installation You should not install or remove cards yourself, but should refer installation to a qualified TASCAM distributor. Otherwise, the warranty will be voided. 1 2 Turn off the main unit and disconnect it from the power supply.
1 – Introduction : Connections A new unit’s card slot and/or new card may be a little stiff. Make sure that the card is pushed as far as it will go (so that the card rear connector plate touches the rear panel of the unit). 5 Use the screws supplied with the card to attach the rear panel of the interface card to the rear panel of the unit. 6 Repeat the installation process for all the interface cards that you are fitting.
2 – Using the card You can access the card’s functions by pressing the DIGITAL key and selecting the SLOT sub-screen. Figure 2.1: The main surround monitor screen The surround monitor card is here shown installed in slot 2. The top half of this part of the screen shows the different options (referred to as SETUP TARGETs), and the lower half shows the settings for these options. Use the POD 4 encoder1 to highlight the different options available, and the ENTER key to select the option. 1.
2 – Using the card : OPERATION option Soloing channels This works with the same SHIFTed number keys as for muting (see Figure 2.3, SHIFTed number keys used for channel control) as well as the cursor and ENTER key options. There are two solo options—one for an exclusive solo mode, where only one channel at a time is active, and one for a mixed solo mode, where selected channels are active.
2 – Using the card : ROUTING option Notes on other hardware controls MONO key When the card is being used for monitoring in surround mode, the MONO key on the control surface is used to turn downmix on and off (as set up in DOWN MIX). DIM key The DIM key on the control surface can be used in the usual way to dim the outputs from the card. The dimming level is set in the mixer. ROUTING option There are two main functions here.
2 – Using the card : DOWNMIX option DOWNMIX option Downmixing is the process of folding a surround mix into a formats using fewer channels. This is done for the purpose of checking compatibility. The patterns available depend on the source format currently in use: Source pattern 6.1 Available downmix targets 5.1 2.1 Stereo Mono 5.1 LRCS (rear phantom center) LRCS (rear hard center) 2.
2 – Using the card : DOWNMIX option 6.1 format 6.1 > 5.1 In the 6.1 to 5.1 downmix, the attenuation values are: 6.1 > stereo In the 6.1 to stereo downmix, the attenuation values are: Values in dB (default underscored) Source > Target CS (LC)>LS,RS Source > Target -3, –4.5, –6 Values in dB (default underscored) C > L,R 0, –1.5, –3, –4.
2 – Using the card : DOWNMIX option 5.1 format 5.1 > LRCS (rear phantom) In the 5.1 to LRCS downmix with a phantom rear speaker, the attenuation values are: Source > Target Values in dB (default underscored) LFE >C –3, –6, –9, –∞ LFE>L,R –3, –6, –9, –∞ LS>LS summed and attenuated (–3) RS>RS 5.1 > 2.1 In the 5.1 to 4.1 downmix, the attenuation values are: Source > Target C >L,R 0, –1.5, –3, –4.
2 – Using the card : DOWNMIX option 5.1 > mono In the 5.1 to mono downmix, the attenuation values are: Source > Target Values in dB (default underscored) C > L+R 0, –1.5, –3, –4.5, –6 LFE>L+R –3, –6, –9, –∞ LS,RS>L+R 0, –3, –6, –∞ L>L summed and attenuated (–3) R>R L L –3 R C R –3 mute C mute LFE mute LS 0, –1.5, –3, –4.5, –6 LFE –inf –3, –6, –9, –inf LS –3 0, –3, –6, –inf RS mute RS LC mute LC RC mute RC –3 Table 2.14: 5.
2 – Using the card : DOWNMIX option LRCS > mono In the LRCS to mono down- LRCS > LRCS (phantom) In the LRCS mix, the attenuation values are: to LRCS with a phantom center rear speaker, the attenuation values are: Source > Target Values in dB (default underscored) C >L+R 0, –1.5, –3, –4.
2 – Using the card : BASS MANAGEMENT option BASS MANAGEMENT option The BASS MANAGEMENT screen allows the selection of one of two bass management techniques, Type 1 and Type 2. These are illustrated graphically below as they are implemented in 5.1 surround mode. Figure 2.19: BASS MANAGMENT option screen Figure 2.20: Type 1 and Type 2 bass management for 5.1 and 6.
2 – Using the card : MONITOR ALIGNMENT option MONITOR ALIGNMENT option This allows the setup of the surround speakers and levels. Figure 2.21: MONITOR ALIGNMENT option screen Trimming the levels When monitoring in surround mode, it is important that the perceived level of each channel (as perceived from the monitoring position) is equal, in order to achieve a satisfactory mix.
2 – Using the card : MONITOR ALIGNMENT option Generating the pink noise Make sure that your monitoring system is turned on, and adjusted to a reasonable working level. 1 Use the MONITOR / OSC/COM screen to set up the oscillator to produce pink noise. 2 Set the level. If you are working to the SMPTE standard, -20 corresponds to the analog nominal level (the EBU equivalent is -18). 3 Route the oscillator to the surround busses (“Oscillator routing” on page 6).
2 – Using the card : MONITOR ALIGNMENT option Setting the overall surround level This is set on the OPERATION screen after the channels have been aligned. For movie work, this is standardized at 85dBC, and for television at 82dBC1. Musical program material may use a higher reference level. 1 Turn down the level of the monitoring system. 2 Set the value of the desired reference level on the SPL REFERENCE field of the OPERATION screen.
