14 StoRING A PReSet Once you ’ ve edited a preset, you can store it on the PCM96 Surround (in the U ser categor y) or on a Compact F lash card (in the Card category). N ote : When you first inser t a Compact F lash card, you may receive the message “Car d N eeds Initializing.
15 INItIALIzING/FoRMA ttING A coMP Act FLASh cARd T o initialize or format a Compact F lash card: P ress the Back button until the P reset screen appears. 1. P ress the Machine button until System View is displayed. 2. P ress the Select knob to enter the System M enu.
1 6 dSP coNFIGURA tIoNS The PCM96 Surround processor can be divided in up to four virtual machines, each of which can r un its own algorithm. This lets you route sig- nals from each input through a variety of algorithm combinations .
17 When dealing with true surround source material, the choice of configu- ration is simple--choose the 4-in or 5-in version. The algorithms are all designed to treat the inputs uniquely . If the algorithm is a reverberator or room, then each input will propagate into the space from the direction of its virtual source.
18 cAScAde SteReo The left and right signals are processed together in one vir tual machine, and the resulting signal is sent to a second virtual machine, where they are again processed together . dUAL MoNo The left signal travels through one virtual machine, and the right signal travels through a separate second vir tual machine.
19 SINGLe tWo IN FIVe oUt T wo signals are processed by one virtual machine, and output as five signals. SINGLe FIVe IN FIVe oUt F ive signals are processed by one vir tual machine, and output as five signals. SINGLe SIx IN SIx oUt Six signals are processed by one virtual machine, and output as six signals.
20 the PcM96 SURRoUNd PLUG-IN The plug-in lets you add PCM96 Surr ound reverbs and effects to projects on your Digital Audio W orkstation (DA W ). INSt ALLING the PLUG-IN SoFtW ARe T o install the PCM96 Surround plug-in: Double-click the PCM96_Surr ound_Installer x.
21 Click the single down arrow in the lower right corner to open the second plug-in control area. In the second control area, you can adjust the soft row parameters by click- ing on and moving the sliders. N ote that the soft ro w parameters vary from preset to preset.
22 In the third control area (located at the bottom of the plug-in), you can adjust all the parameters in the preset by clicking on and moving the sliders. Y ou can select different groups of parameters to adjust by clicking the but- tons in the row at the top of the third control area (in the example above, I/O Levels, Input Control, Shape, etc.
23 Locate Click to make the PCM96 Surround display flash, so you can easily find the curently selected PCM96 Surround in a large rack full of PCM96 S urrounds.
24 NetWoRKING This section provides a step-by-step guide on how to properly connect the PCM96 S urround to a Local Area N etwork (LAN) for several different net- work architectures. The first topology is a simple direct connection using the provided Ethernet cable.
25 SUbNet A small network within a larger network. For example, a T CP/IP network might be a subnet of a venue ’ s network, which could include computers throughout the building, or a network might be divided into subnets. For example, in a large installation, there may be one subnet per rack or room.
26 VIRtUAL PRIV A te NetWoRKS (VPN) Virtual private networks (VPN) pro vide an encr ypted connection (or tunnel) between networks or between a network and a user o ver a public network (such as the Internet). Instead of using a dedicated, r eal-world connection such as a leased line, a VPN uses virtual connections through the public network.
27 your firewall to allow the System Architect software and/or port 3804 tcp and udp to pass through the firewall. etheRNet LINK Make sure that you have a valid E thernet connection by looking at the link status lights. Most Ethernet devices will have some kind of indicator that shows the link is present.
28 SySteM MeNU The System Menu lets you adjust several settings in the PCM96 Surround. T o access the System Menu, press the Select knob while a System P reset is loaded. The System Menu contains sub-menus and options . S ub-menus contain options and/or more sub-menus.
29 Confi dence Erro r - “0” indicate s no prob lem. “1” indicates the PCM96 S urroun d is detec ting exces sive jitter or noise on the digital audio line. N o data has been corrupted, but correctiv e action should be taken. Sample Slip - An unchanging number indicates you are not slipping samples.
30 Base Channel Select the connected MIDI device’ s base channel here. Choose from 0-15. Bank Dump Lets you copy an entir e ban k of pres ets from the PCM96 Su rround to anoth er dev ice via MIDI. (F or a map of banks and prese ts, see pag e 29; to see the current pre set’ s bank number , press Knob C while viewing the P reset screen.
31 MAchINe MeNU The Machine menu lets you adjust settings for a single vir tual machine. T o access the Machine menu, press the Select knob while a Machine Pr eset is loaded. The sub-menus var y depending on what algorithm is active. SoFt RoW SetUP This sub-menu lets you assign parameters to a Machine P reset ’ s soft row .
32 USING MIdI The MIDI Control menu is where all MIDI related control is changed. See page 24 for information about the MIDI Control menu. MIdI IMPLeMeNt A tIoN The PCM96 Surround offers MIDI implementation for use with external MIDI har dware and software controllers.
33 N ow the PCM96 S urround unit is identified by the selected base channel, and virtual machines 1, 2, 3, and 4 within the PCM96 S urround are identi- fied by the base channel plus 1, 2, 3, and 4, respectively . chANNeL MAP (hoW chANNeLS MAP to MAchINeS) Channel U sage Description Base Channel System Level Use for loading System presets.

36 coMMANd 2: ReQUeSt PReSet bANK dUMP When this command is receiv ed by the PCM96 Surr ound, it will respond with a series of preset dumps for all presets in the bank. Blank presets will be transmitted in a special form. Only presets from U ser banks may be request- ed.
37 the ALGoRIthMS chAMbeR (SURRoUNd, SteReo ANd MoNo) Chamber is a complex miniature-space effect resembling an echo chamber at its smaller settings and, at its larger ones, a small performance space with a more rapid build-up of reflection density than a hall.
38 Random Delays are similar to Simple Delays, but are especially useful for: • M ultitap T ape Loops F eedb ack can be used to recir culate delay s. Approp riate use of hi ghpass and lowp ass filters emula tes the ban dpass effect s of multi- generati onal tape loops (hiss not included).
39 RANdoM hALL (SURRoUNd, SteReo ANd MoNo) Random Hall is a hall effect with gradual build-up, well suited to complex sounds like orchestral music. Its reverberators change over time in controlled random ways to avoid the buildup of tinny , grainy , metallic, or other color- ations.
40 ReSoNANt choRdS (SURRoUNd, SteReo ANd MoNo) The Resonant Chord algorithm uses impulsive energy at the inputs to excite six resonant voices (notes). The level, pitch, duration, and high-frequency cutoff of the overtones for each voice are separately controllable.
41 round-robin. F or example, if MIDI note numbers are used to assign pitch, the resonators will constantly be re-tuned to the pitches of the last six MIDI notes receiv ed. (This can produce an effect similar to playing a piano with the sustain pedal depressed.
42 sets themselves may be loaded into either type of machine, with the appro- priate number of voices appearing. Ev er y effor t is made to make the factory presets sound alike in both formats, but it is possible to may presets that work ver y differently , based on machine type.
43 the P ARAMeteRS The PCM 96 contains hundreds of presets, covering just about every pos- sible need. But you can refine and customize any preset by adjusting its parameters . P arameters are the building blocks within each preset that deter- mine how it sounds and behaves.
44 Category (Room) This parameter lets you select a specific category from which a room response may be chosen. Changes here have a direct effect on the P attern Selector parameter . Chorus Depth (Concert Hall) This parameter controls the amount of randomization of the chorus tap.
45 Feedback This controls the amount of echo output that is fed back to the input of the echo buffer . The actual feedback level is modified by the Master Echo F eedback param- eter , if present. The master value is a percentage (0-100%) that is applied to the Echo F eedback level.
46 This tells the shifter the lowest frequency that it may be required to shift. As a general rule of thumb, this should be set in the higher part of the range in order to preserve detail in the shifted material. It should be low ered if arti- facts appear in the low frequencies.
47 there may be one or more reflection delays for each input channel. Some of the delays may mix their outputs to the same channel (left to left) and some may go cross-channel (left to right). Reflection Gain (Level) Each Reflection Delay voice also has a gain value.
48 Reverb Spin (Spin) This is usually simply called spin. It controls the speed of the reverb random- izer . S pin is also connected with the Reverb W ander parameter Reverb T ime Hi Cut This parameter , also known as Hicut or R THC is a low-pass filter in the recirculating part of the reverb.
49 Tip : Shape will not have this effect if spread is at its minimum value. B ut even then, it can make a difference. In this case, it affects reverb tim - bre and densit y . High er values of shape will be both darker and denser , although the effect is subtle.
50 components of the reverb except for early reflections, etc.) is passed through a simple 2x2 matrix. This provides an encoding of the tail that dramatically changes its spatial characteristics. The tail can be changed to feel narrower (even down to mono) or wider than normal stereo.
