Important Information

Read the following before using the SREV1

Warnings

• Do not subject the unit to extreme temperatures, humidity, direct sunlight, or dust, which could be a potential ﬁre or electrical shock hazard.

• Do not allow water to enter the unit or allow it to get wet. Fire or electrical shock may result.

• Connect the power cord or AC adapter only to an AC outlet of the type stated in this

Owner’s Manual or as marked on the unit. Failure to do so is a ﬁre and electrical shock

hazard.

• Hold the power-cord plug or AC adapter when disconnecting from an AC outlet. Never pull the cord. A power cord damaged through pulling is a potential ﬁre and electrical shock hazard.

• Do not touch the power plug or AC adapter with wet hands. Doing so is a potential electrical shock hazard.

• Do not place heavy objects, including the unit, on top of the power cord. A damaged power cord is a ﬁre and electrical shock hazard. In particular, be careful not to place heavy objects on a power cord covered by a carpet.

• Do not place a container with liquid or small metal objects on top of this unit. Liquid or metal objects inside this unit are a ﬁre and electrical shock hazard.

• Do not scratch, bend, twist, pull, or heat the power cord. A damaged power cord is a ﬁre and electrical shock hazard.

• If the power cord is damaged (e.g., cut or a bare wire is exposed), ask your dealer for a replacement. Using the unit with a damaged power cord is a ﬁre and electrical shock hazard.

• Do not plug several pieces of equipment into the same AC outlet. This may overload the AC outlet, and could be a ﬁre or electrical shock hazard. It may also affect the performance of some equipment.

• If you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid gets inside the unit, turn it off immediately. Remove the power cord or AC adapter from the AC outlet and consult your dealer for repair. Using a unit in this condition is a ﬁre and electrical shock hazard.

• Do not place small objects on top of the unit. Metal objects falling inside is a ﬁre and electrical shock hazard.

• If a foreign object or water gets inside the unit, turn it off immediately. Remove the power cord or AC adapter from the AC outlet and consult your dealer for repair. Using a unit in this condition is a potential ﬁre and electrical shock hazard.

• If the unit is dropped or the cabinet damaged, turn off the power, remove the power plug or AC adapter from the AC outlet, and contact your dealer. If you continue using the unit without heeding this instruction, ﬁre or electrical shock may result.

• Do not remove the unit covers. You could receive an electrical shock. If you think internal inspection, maintenance, or repair is necessary, contact your dealer.

• Do not attempt to modify the unit. This is a potential ﬁre and electrical shock hazard.

SREV1—Owner’s Manual

Important Information

• Do not block the front panel air inlet, ventilation slots, or fan outlets. Doing so is a potential ﬁre hazard.

Cautions

• Allow enough free space around the SREV1 for normal ventilation. This should be 20 cm behind, 10 cm at the sides, and 30 cm above. These distances should also be adopted when rack-mounting the SREV1. If the SREV1 is mounted in a portable rack case, keep the rear of the case open when using the SREV1 so as not to obstruct the ﬂow of air from the two cooling fans. If the airﬂow is not adequate, the SREV1 will heat up inside and may cause a ﬁre. Do not mount the SREV1 above equipment that produces a lot of heat, such as a power ampliﬁer.

• Turn off all audio equipment when connecting to the unit, and use only cables of the type speciﬁed in this

• If you plan not to use the unit for a long period of time, remove the power cord or AC adapter from the AC outlet. Leaving the unit connected is a potential ﬁre hazard.

• Do not use benzene, thinner, cleaning detergent, or a chemical cloth to clean the unit. Use only a soft, dry cloth.

• If the unit is stored in a cold place (e.g., overnight in a car), and then moved to a warmer environment, or if the temperature rises sharply, condensation may form inside the unit, which may affect performance. In this case, the unit should be allowed to acclimatize for about one hour before use.

Owner’s Manual.

• When the wordclock is changed on the wordclock master device, noise may occur from the SREV1’s outputs, especially if an MY8-AT I/O card is installed, so turn down your power amps beforehand, otherwise any connected speakers may be damaged.

• If the RC-SREV1 displays the message “LOW BATTERY” when you turn on the unit, ask your Yamaha dealer to replace the internal battery as soon as possible. The unit will still work, but data other than backed up data will be lost. We recommend that you save this data to a PC Card before replacing the battery.

• For electrical safety reasons, it’s important that the SREV1 is grounded properly. The supplied power cord has a three-pin plug, and if the ground terminal of the AC outlet is grounded, then the SREV1 will be grounded sufﬁciently through the power cord. If the AC outlet does not provide a suitable ground, however, a ground connection should be made to the dedicated grounding screw.

Handling CD-ROMs

• Use only discs of the type speciﬁed in this Owner’s Manual .

• The CD-ROM drive is for use with data discs only. Never insert audio CDs.

• Store discs in a place free from extreme temperatures, humidity, dust, and dirt.

• Always store discs in their cases.

• When handling discs, be careful not to touch the surface. Hold discs by the edge. Fingerprints, smudges, scratches, or dirt can affect performance.

• Be careful not to scratch the labeled side of the disc. Even scratches on that side can affect performance.

• Fingerprints and dust should be removed by wiping gently from the center of the disc towards the disc edge, using a soft, dry cloth. Never wipe in a circular motion and never rub a disc hard with a dry cloth.

• For stubborn stains and dirt, use a cleaning kit designed speciﬁcally for use with CDs. Do not use benzene, thinner, cleaning detergent, or a chemical cloth.

• For disc marking, use only pens speciﬁcally designed for writing on CDs and write only on the designated area. Do not attach a label to a disc.

• If a disc is stored in a cold place (e.g., overnight in a car), and then moved to a warmer environment, or if the temperature rises sharply, condensation may form on the disc surface, which may affect performance. In this case, the disc should be allowed to acclimatize for about one hour before use.

• Do not under any circumstances attempt to use discs that are cracked or warped. Doing so may seriously damage the unit.

Handling PC Cards

• Use only PC Cards of the type speciﬁed in this Owner’s Manual .

• Some PC Cards and PC Card adapters cannot be used with the SREV1.

• Do not eject a PC Card while the activity indicator is lit. Doing so may cause data lose.

• Store PC Cards in a place free from extreme temperatures, humidity, dust, and dirt.

• Always store PC Cards in their cases.

Precautions for Transportation

During transportation, keep the CD-ROM door shut with tape, or a pad, or the like.

• When using tape, use tape that adheres well to the front panel.

• When using a pad, use a pad stiff enough that the elasticity holds the tray in place.

Chapter 1—Welcome

Welcome to the SREV1

Thank you for choosing the Yamaha SREV1 Sampling Reverberator. Unlike conventional digital reverberators, which synthesize reverberation using con-

trived signal-processing algorithms, the new SREV1 Sampling Reverberator from Yamaha employs digital convolution processing to impose an acoustic “ﬁngerprint” of a previously measured environment onto any audio signal, faithfully recreating the original reverberation, with accurate reﬂection detail identical to that produced had the sound been heard in that environment. The SREV1 is perfect for recording studios, audio post, broadcast, concert halls, theaters, or anyone looking for superb quality reverb that sounds just like the real thing, with the option to sample the reverberation characteristics of any location for use back in the studio.

The SREV1 in a Nutshell

Sonic “ﬁngerprints” are produced by measuring the impulse response (i.e., acoustic characteristics) of an environment, which involves “blasting out” time-stretched pulses through an accurate speaker system and recording the results via carefully placed microphones. The resultant impulse-response data can then be used by the SREV1 to convolve the captured acoustic characteristics onto any audio signal.

In addition to stereo reverb (2-channel mode), the SREV1 offers four-channel processing for surround reverb (4-channel mode). Alternatively, the SREV1 can be conﬁgured as two fully independent reverberators (2-channel x2 mode), each with its own inputs, outputs, and program settings.

SREV1—Owner’s Manual

Thirty-two of Yamaha’s new convolution chips provide the necessary “horsepower” for real-time convolution of up to 5.46 seconds per channel (2-channel mode), 2.73 seconds per channel (4-channel or 2-channel x2 mode). Featuring an additional 32 convolution chips, the optional DB-SREV1 DSP Expansion Board doubles the available convolution time to a maximum of 10.92 seconds per channel (2-channel mode), 5.46 seconds per channel (4-channel or 2-channel x2 mode).

Measured impulse response data is combined with variable parameters such as reverb time and initial delay to form reverb

programs

, which can be stored in special

Quick

memories or the Internal Card or PC Card. Up to six programs can be stored in Quick

memory in 2-channel or 4-channel mode; 12 in 2-channel x2 mode. Programs in Quick memory can be recalled instantly via the optional RC-SREV1 Remote Controller or MIDI Program Changes.

Projects, which contain all the Quick memory programs and the current program settings, provide a convenient way to manage programs and settings for each job. Projects can be stored on the Internal Card or PC Card.

The PC Card slot is fully compatible with the PC Card ATA speciﬁcation and supports the FAT16 ﬁle system. The CD-ROM drive supports the ISO9660 Level 2 format. Both the PC Card and CD-ROM format is compatible with Windows.

The supplied CD-ROM contains preset reverb programs of famous venues from around the world, and a CD-ROM library is planned for future release. The preset programs on the supplied CD-ROM are loaded into the Internal Card at the factory.

Program editing is handled at two levels: Main parameters and Fine parameters. With Main parameter editing, channel parameters, such as reverb time, initial delay, reverb balance, EQ, etc., are grouped, so that, for example, the reverb time of all channels can be set simultaneously. Fine parameter editing adds pre-convolution 4-band PEQ, post-convolution 4-band PEQ, and impulse-response data loading. Reverb parameters can be edited individually or grouped. Reverb balance and reverb level parameters for each channel can be controlled individually via MIDI Control Changes.

Two AES/EBU inputs and outputs (providing 4 channels) are built in and two mini YGDAI (Yamaha General Digital Audio Interface) slots offer various analog and digital I/O options (AES/EBU, ADAT, Tascam). Inputs can be assigned to channels individually, allowing various input/output conﬁgurations. In 2-channel mode, for example, a single input can be assigned to both channels (left and right) for mono in/stereo out operation, or an individual input can be assigned to each channel for true stereo in/stereo out operation.

Superb sonic performance is provided by Yamaha’s new convolution chip, 24-bit I/O, 32-bit internal signal processing, and 48 kHz internal wordclock. External wordclocks of 44.1 kHz and 48 kHz are supported and can be sourced via the dedicated BNC wordclock input, AES/EBU inputs, or card slot inputs.

Up to four SREV1s can be controlled using the optional RC-SREV1 Remote Controller, which features a large 320 x 240 dot graphical display, with ﬂuorescent backlight and adjustable brightness and contrast, four motorized faders for parameter editing, and input and output clip indicators. Power is supplied by the SREV1.

SREV1 Basics

Reverb Modes

The SREV1 offers three Reverb modes: 2-channel, 4-channel, and 2-channel x2. In 2-channel mode, the SREV1 functions as a stereo reverb processor. Use this mode if all you require is stereo outputs, as it offers the maximum convolution time per channel. In 4-channel mode, the SREV1 offers 4-channel processing for surround reverb. In 2-channel x2 mode, the SREV1 functions as two independent stereo reverb processors (A and B).

See page 34 for information on selecting Reverb modes. The onboard AES/EBU inputs and mini YGDAI slot inputs can be freely assigned to

channels. See “Assigning Inputs” on page 35 for more information.

Convolution Times

The following table shows the maximum convolution time available per channel for each mode with and without the optional DB-SREV1 DSP Expansion Board installed.

Base System

5.46 sec 10.92 sec

2.73 sec 5.46 sec

with DSP Expansion Board

(DB-SREV1)

Convolution time is not the same as reverb time. Reverb time is the time it takes the reverb to decay to –60 dB, and more convolution is required to provide reverberation to –90 dB or –120 dB, so the convolution time must be between 1.5 and 2 times more than the reverb time.

Impulse-Response Data

Impulse-response data contains the impulse-response information (i.e., acoustic characteristics) of a measured environment. Preset programs come with their own impulse-response data. Each channel of a program is assigned impulse-response data, as shown below, and data can be loaded for channels individually on the Data Load pages. See “Loading Impulse-Response Data” on page 61 for more information. The impulse-response data for the preset programs is loaded into the Internal Card at the factory. It’s also on the supplied CD-ROM.

Programs

There are two types of reverb program: 2-channel and 4-channel. Two-channel programs are for use with 2-channel mode and 2-channel x2 mode, while 4-channel programs are for use only with 4-channel mode. In 2-channel mode, 4-channel programs do not appear in the program lists and vice versa. The preset programs on the supplied CD-ROM are loaded into the Internal Card at the factory. User programs can be stored in the Quick memories, Internal Card or PC Card, where they can be write-protected.

Projects

Projects contain all the Quick memory programs and the current program settings and free you to leave a project and come back to it at any time. Projects can be saved to the Internal Card or PC Card, where they can be write-protected.

There are three types of project: 2-channel, 4-channel, and 2-channel x2. Each project type is available only when the corresponding mode is selected. You can’t, for example, select a 2-channel project in 4-channel mode. Projects are managed on the Project pages. See “Working with Projects” on page 48 for more information.

Quick Memories

Quick memories are special memories for storing programs. Unlike programs on the Internal Card, PC Cards, and CD-ROMs, which take time to load, Quick memory programs can be recalled instantly. There are six Quick memories available in 2-channel or 4-channel mode; 12 in 2-channel x2 mode. Quick memories are managed on the Program pages. See “Working with Quick Memories” on page 42 for more information.

SREV1—Owner’s Manual

Chapter 1—Welcome

Drives

Programs, projects, and impulse-response data can be loaded from the following drives: Internal Card, PC Card, or CD-ROM. The number of programs that can be stored on each drive depends on its capacity and the size of the associated impulse-response data. Programs and drives are managed on the Library pages. See “Working with the Library” on page 45 for more information.

The following diagram shows how programs and projects can be transferred to and from the drives and Quick memories, and impulse-response data transferred from the drives.

32 Chapter 4—Basic Operation

SREV1 Startup

When the SREV1 is turned on, its INPUT and OUTPUT signal indicators light up in sequence. During this time, the SREV1 loads impulse-response data for the current program and the programs in Quick memory from the Internal Card, and, if necessary, from the PC Card or CD-ROM. At this time, the SREV1 cannot be used. After about 30 seconds, when the necessary impulse-response data has been loaded, the CLIP and SIGNAL indicators go out and the SREV1 is ready for use.

Note that the startup time will be different if the current program or the programs in Quick memory are on PC Card or CD-ROM.

If the SREV1 does not output any sound, check your audio connections, and the input assignments. See “Assigning Inputs” on page 35 for more information.

RC-SREV1 Startup

In Principle, the RC-SREV1 should be started up after the SREV1 has completed its startup. However, when the RC-SREV1 is connected to one SREV1 using the supplied remote cable, and that SREV1 is supplying power to the RC-SREV1, so long as the RC-SREV1 POWER switch is set to the ON position, the RC-SREV1 will be turned on at the same time as the SREV1 is turned on, and the RC-SREV1 will startup normally. If, however, you are using multiple SREV1s, connected together using serial cables, make sure that all SREV1s have completed startup before turning on the RC-SREV1.

When the RC-SREV1 is turned on, startup screen 1 appears for one second. Then startup screen 2 appears with an animated waveform moving from left to right. During this time, the RC-SREV1 receives necessary operating information from the SREV1 via the serial cable. When all the information has been received, the Program page appears.

When the RC-SREV1 is turned on after the SREV1 has completed its startup, the above procedure takes 15 seconds.

When the RC-SREV1 is turned on at the same time as the SREV1, it takes 45 seconds to start up, although the actual time will depend on the time it takes the SREV1 to start up.

If there is no animation on startup screen 2, there may be a communication error between the SREV1 and RC-SREV1. In this case, turn off both units and check the remote cable connections, also check for breaks in the cable.

SREV1—Owner’s Manual

About the Internal Operations at Startup 33

About the Internal Operations at Startup

During startup, the SREV1 loads the necessary programs into the current and Quick program memories in order to restore the SREV1 to the same state it was in before it was last turned off. If any of these programs were previously loaded from a PC Card or CD-ROM and then stored to a Quick memory, the same PC Card or CD-ROM will be required to restore the contents of the Quick memories. In this case, be sure to insert the necessary PC Card or CD-ROM before starting the SREV1. Although the SREV1’s battery-backed memory stores the titles of the current and Quick memory programs, it does not store the actual program or impulse-response data, so this must be loaded each time the SREV1 is started.

If a necessary PC Card or CD-ROM is not inserted, the message “DATA FILE NOT FOUND! INSERT PCMCIA CARD” or “DATA FILE NOT FOUND! INSERT CD-ROM DISC” appears once the RC-SREV1 has completed startup. In this case, insert the necessary PC Card or CD-ROM and try loading again.

Note that the above information regarding necessary PC Cards and CD-ROMs also applies to changing the Reverb mode and loading projects.

SREV1—Owner’s Manual

Metering 37

Metering

Input and output signal levels can be metered in several places: the 14-segment meters on the RC-SREV1 display pages, the 11-segment meters on the Meter I/O page, the SIGNAL and CLIP indicators on the SREV1, and the CLIP indicators on the RC-SREV1. The Peak Hold function works with all of these meters. See “Using Peak Hold” on page 39 for more information.

14-segment Meters

Input and output signal levels can be metered by using the 14-segment meters that appear on most RC-SREV1 display pages. In 2-channel mode, input and output signal levels can be metered simultaneously. In 4-channel or 2-channel x2 mode, however, either the input or output levels can be metered, not both simultaneously. See “Setting the Meter Mode” on page 39 for more information.

The 14-segment LCD meters have the following resolution: CLIP / –3dB / –6dB / –9dB / –12dB / –15dB / –18dB / –24dB / –30dB / –36dB / –42dB / –48dB / –54dB / –60dB.

Main 1 Parameters

Basic parameters, including Reverb Time, Initial Delay, Pre EQ Low Gain, and Pre EQ High Gain, can be adjusted on the Main 1 pages. In 2-channel x2 mode, two Main 1 pages are available: Main1-A and Main1-B. Channels are grouped, so adjusting, say, the Reverb Time parameter, adjusts the reverb time of all channels simultaneously. In 2-channel x2 mode, A and B parameters are grouped independently. These parameters can be adjusted for each channel individually on the Fine parameter pages. See page 56 and page 57 for more information.

The graphs and parameter values of only one channel are displayed at a time. You can choose which channel by using the buttons in the DISPLAY CHANNEL section of the page. Below that section is the REV graph, which displays the reverb parameter settings graphically, and the PRE-EQ graph, which displays the Pre EQ settings graphically. If the EQ is turned off on the Pre EQ page (see page 57), the EQ graph appears shaded.

The Main 1 pages for each mode are shown below.

Main 1 Parameters 53

Note that since adjustments to the REV TIME parameter do not take effect immediately, there is a small delay between adjusting the reverb time by using, for example, a fader and the new reverb time being applied.

The parameter ranges are as follows.

The following waveforms show the reverb produced by a snare drum with reverb times of 500 milliseconds and 2.0 seconds. Initial delay is 0.1 milliseconds; reverb balance is 100%. The third waveform shows how reﬂections can be delayed by using the Initial Delay parameter. Here the reverb time is 2.0 seconds; initial delay is 200 ms (exaggerated for illustration clarity); and the reverb balance is 50%.

SREV1—Owner’s Manual

62 Chapter 5—Editing Programs

Impulse-response data (TM4 format) created by using IRSampler, the impulse-response sampling software, or IREdit, the impulse-response editing software, can be loaded into the SREV1 from a PC Card. The RC-SREV1 looks for impulse-response data stored in the “\yamaha\srev\data” folder of the PC Card, so you need to make a new folder called “data” in “x:\yamaha\srev\” and then copy your impulse-response data into it. (Note that “x” refers to the letter assigned to your PC Card while it’s inserted in your PC.)

The 2-channel (SP2) and 4-channel (SP4) programs that you create are stored in the “\yamaha\srev\prog” folder, and 2-channel, 4-channel, and 2-channel x2 projects are stored in the “\yamaha\srev\proj” folder. When you copy or move any of these ﬁles to another PC Card by using your PC, be sure to use the same folder organization and naming, otherwise, the SREV1 will not be able to ﬁnd the ﬁles.

Note that the SREV1 can only list up to 128 ﬁles in a folder, so do not put any more ﬁles than that into a folder. If you do have more than 128 ﬁles in a folder, the SREV1 lists the ﬁrst 128 ﬁles copied to the folder in alphabetical order.

MIDI & the SREV1

The SREV1 supports the following MIDI messages:

• Program Changes to recall up to 12 Quick memory programs

• Control Changes for Reverb Balance and Reverb Level control

These MIDI messages are not transmitted when actions are performed on RC-SREV1. Quick memory programs can be assigned to MIDI Program Changes and then recalled

remotely from other MIDI equipment. When a Program Change message is received, the program stored in the assigned Quick memory is recalled. See “Assigning Quick Memory Programs to Program Changes” on page 70 for more information.

The Reverb Balance and Reverb Level parameters for each channel can be assigned to MIDI Control Changes and then controlled remotely from other MIDI equipment. When a Control Change message is received, the assigned parameter is controlled. See “Assigning Parameters to Control Changes” on page 71 for more information.

The SREV1 can be set to receive Program Change and Control Change messages on any MIDI Channel from 1 through 16, and in 2-channel x2 mode, individual MIDI Channels can be set for A and B. See “Setting the MIDI Receive Channels” on page 69 for more information.

Note: Do not control the SREV1 by using MIDI messages and the RC-SREV1 simultaneously.

MIDI Ports

The MIDI IN and OUT ports are used to transmit and receive MIDI messages. The MIDI IN port receives messages, while the MIDI OUT port currently echoes the messages received at the MIDI IN port, essentially like a MIDI THRU port.

Assigning Parameters to Control Changes 71

Assigning Parameters to Control Changes

Reverb Balance and Reverb Level parameters for each channel can be assigned to MIDI Control Changes 0 through 95.

1 Use the [UTILITY] button to locate the MIDI page.

2 Use the cursor buttons to select the REV BALANCE or REV LEVEL assignments

in the CONTROL CHANGE section of the page.

In 2-channel mode, these are L-CH and R-CH. In 4-channel mode, Front-L, Front-R, Rear-L, and Rear-R. And in 2-channel x2 mode, A-L, A-R, B-L, and B-R.

3 Use the DATA wheel or [–1/DEC] and [+1/INC] buttons to assign a Control

Change to OFF or 0 through 95.

When a Control Change message is received, the assigned parameter is controlled. If the Rev page is selected, you can see the parameter value update, and if the parameter is the currently selected parameter, then the corresponding fader moves as well.

If a Control Change is assigned to more than one parameter, all the assigned parameters are controlled when that Control Change is received.

Since Control Changes are assigned to channels individually, they are not affected by the GROUP button on the Rev page. Even if channels are grouped, only the assigned channel parameter is controlled when a Control Change message is received.

SREV1

If a page selected by using the [PARAMETER FINE] button is displayed when a Control Change message is received, the corresponding fader moves and the graph and parameter values change, causing the Edit status indicator to appear.

If a page selected by using the [PARAMETER MAIN] button is displayed when a Control Change message is received, the corresponding fader, graph, and parameter value do not change. Only the Edit status indicator appears. To update the fader, graph, and parameter value, select another page, then select the previous page again.

The following illustration shows the type of MIDI equipment that can be used with the SREV1 for remote parameter control using Control Change messages.

74 Chapter 8—Wordclocks

Wordclocks & the SREV1

Unlike analog audio equipment, digital audio equipment must be synchronized when digital audio signals are transferred from one device to another, otherwise, signals may not be received correctly and audible noise, glitches, or clicks may occur. Synchronization is achieved using what’s called a wordclock, which is a clock signal for synchronizing all the digital audio signals in a system. Note that wordclocks are not the same as SMPTE/EBU timecode or MIDI timecode, which are typically used to synchronize tape machines, MIDI sequencers, and so on. Wordclock synchronization refers to the synchronization of the digital audio processing circuits inside each digital audio device.

In a typical digital audio system, one device operates as the wordclock master, and the other devices operate as wordclock slaves, synchronizing to the wordclock master. Wordclock signals can be distributed via dedicated cables, typically BNC cables, or derived from digital audio connections, such as AES/EBU.

If you’re connecting to the SREV1 using only analog inputs and outputs, no special wordclock settings are required, and the SREV1 can be set to use its own internally generated wordclock. If you’re connecting other equipment digitally, however, you must decide which device to use as the wordclock master and which devices to use as slaves.

The SREV1 can be used as a 48 kHz wordclock master, or slaved to an external wordclock source of 44.1 kHz or 48 kHz. It can receive an external wordclock signal via an AES/EBU input, SLOT input, or the BNC WORD CLOCK IN connector.

In a system where all devices share a common wordclock, it’s important that all devices be turned on even if they’re not being used. Turn on the wordclock master ﬁrst, and then the slaves. When shutting down the system, turn off the slaves ﬁrst, and then the master. Before use, make sure that the wordclock slaves are correctly locked to the wordclock master. Most devices have front panel indicators, similar to the FS LOCK indicators on the SREV1, to show when they are wordclock locked. Refer to the relevant owner’s manuals for more information.

When the wordclock source is changed, lower the volume of your system just in case a device becomes unlocked and outputs any unpleasant noises.

Wordclock Connections

The WORD CLOCK IN BNC connector is used to receive wordclock signals from other digital audio equipment. When the wordclock source is set to WCLK IN, the SREV1 locks to the wordclock signal received at the WORD CLOCK IN connector.

See “Wordclock Hookup Examples” on page 78 for more information.

The WORD CLOCK IN is auto-terminating.

WORD CLOCK IN

An external wordclock can also be sourced from an AES/EBU input or the slot input of a digital I/O card.

SREV1—Owner’s Manual

Selecting the Wordclock Source 75

Selecting the Wordclock Source

Note: When the wordclock source is changed on the wordclock master device, noise may occur from the SREV1’s outputs, especially if an MY8-AT I/O card is installed, so turn down your power amps beforehand, otherwise any connected speakers may be damaged.

1 Use the [UTILITY] button to locate the DIO page shown below.

2 Use the cursor buttons to select a source.

The button for the currently selected source appears highlighted. The following wordclock sources can be selected.

3 Press the [ENTER] button to activate the selected source.

The SREV1 checks the selected source to see if a usable wordclock signal is available. If such a signal exists, the SREV1 locks to it and the corresponding FS LOCK indicator,

44.1 kHz or 48 kHz, lights up. If a usable wordclock signal is not found, the SREV1 will not operate and the FS LOCK

indicators ﬂash, as shown in the following table. In this situation, you must select another wordclock source or correct the external wordclock source. This condition also occurs if a previously selected external wordclock source is disconnected, the device supplying it is turned off, or the external wordclock is neither 48 kHz nor 44.1 kHz.

The following table shows the indicator status when the SREV1 is synced and locked to its internal wordclock or an external source.

I/O Options & the SREV1

In addition to the two AES/EBU inputs and outputs, the SREV1 features two mini YGDAI (Yamaha General Digital Audio Interface) slots for use with optional I/O cards, which offer several analog I/O options and digital I/O interfaces in all the popular digital audio interconnect formats, including AES/EBU, ADAT, and Tascam.

The Yamaha AW4416 Audio Workstation, 01V Digital Mixing Console, D24 Digital Multitrack Recorder, DME32 Digital Mixing Engine, AD824 AD Converter, and DA824 DA Converter also use mini YGDAI I/O cards. Note that the “CD” series of YGDAI cards used by the Yamaha 02R Digital Recording Console and 03D Digital Mixing Console are not interchangeable with mini YGDAI cards.

Slot inputs can be freely assigned to SREV1 channels. See “Assigning Inputs” on page 35 for more information. Channel-to-slot output assignments are ﬁxed. See “Output Assignments” on page 9 for more information.

Available I/O Cards

As these speciﬁcations show, analog I/O cards offer either inputs or outputs, while digital I/O cards offer both inputs and outputs.

When an I/O card not listed above, for example, a future addition to the mini YGDAI series, is installed, the message “UNKNOWN CARD” appears.

Choosing I/O Cards

For analog I/O with XLR-type connectors, an MY4-AD card could be installed in, say, SLOT 1, and an MY4-DA card in SLOT 2, although it makes no difference which card is installed in each slot.

To connect the SREV1 to other digital audio equipment, you must determine which digital interconnect format—AES/EBU, ADAT, or Tascam—the other equipment supports, and then install the necessary I/O cards.

The following table shows which cards to use when connecting the SREV1 to other Yamaha digital audio products. Each product can be connected by using the AES/EBU, ADAT, or Tascam interface format.

An external wordclock can be sourced via digital I/O cards. See “Selecting the Word- clock Source” on page 75 for more information.

Using ADAT I/O cards in certain devices can cause wordclock-lock problems, so it’s rec- ommend that you source wordclock signals via I/O cards of another format.

See your Yamaha dealer for more information.

Glossary 93

Glossary

2-channel mode—In this mode the SREV1 functions as a stereo processor. 4-channel mode—In this mode the SREV1 functions as a 4-channel surround pro-

cessor. 2-channel x2 mode—In this mode the SREV1 functions as two independent stereo

processors (A and B). ADAT interconnect format—The digital audio interconnect format typically

found on ADAT-compatible digital audio equipment. Eight channels of digital audio are carried per ﬁber-optic connection using Toslink connectors.

AES/EBU interconnect format—The digital audio interconnect format, estab- lished by the AES (Audio Engineering Society) and EBU (European Broadcasting Union), for transferring digital audio data between professional digital audio equipment. Two channels of digital audio (left/odd and right/even) are carried per balanced line.

CD-ROM (Compact Disc Read Only Memory)— The compact disc format for data storage. Deﬁned in the Yellow Book.

Control Change—A type of MIDI message offering real-time parameter control. Typical Control Changes include Modulation, Volume, Pan, and Portamento.

Convolution—The digital audio process of imposing the characteristics of one signal onto another signal. The SREV1 convolves an acoustic “ﬁngerprint” of a previously measured environment onto an audio signal, faithfully recreating the original reverberation, with accurate reﬂection detail identical to that produced had the sound been heard in that environment.

Convolution time—Convolution time is not the same as reverb time. Reverb time is the time it takes the reverberation to decay by –60 dB, and more convolution is required to provide reverberation down to –90 dB or –120 dB, so the convolution time must be between 1.5 and 2 times more than the reverb time.

DIO—Abbreviation for “digital input and output.” Drives—Programs, projects, and impulse-response data can be stored on the follow-

ing drives: Internal Card, PC Card, or CD-ROM. (The Internal Card is compact ﬂash memory.)

FAT16—The FAT (File Allocation Table) system, developed by Microsoft and sup- ported by MS-DOS and most Windows operating systems, is essentially a database that records where ﬁles are stored on hard disks and other storage media. FAT12 is the original 12-bit version. FAT16 is the 16-bit version, since superseded by the 32-bit version, FAT32, which supports larger storage devices.

FS—Abbreviation for “sampling frequency.” Impulse response—The sound pressure measured at a sensor position set against

the time of an acoustic pulse “ﬁred” from the source position. In other words, an envi- ronment’s acoustical response.

Initial delay—The delay before the reverb reﬂections start. ISO9660 Level 2—A standard format for storing ﬁles and directories on a CD-ROM.

Conforming discs can be read by Macintosh, Windows, UNIX, and other systems. Library—The place used to load, save, title, protect, and delete programs from the

Internal Card, PC Card, and CD-ROM. MIDI (Musical Instrument Digital Interface)—The standard digital interface

for controlling electronic musical systems and audio equipment.

SREV1—Owner’s Manual

94 Glossary

mini YGDAI (Yamaha General Digital Audio Interface)—The second-gener-

ation YGDAI interface system used on the 01V Digital Mixing Console, D24 Digital Multitrack Recorder, DME32 Digital Mixing Engine, and SREV1.

PC Card—A small, credit card-sized device for use with personal computers and other electronic devices. PC Cards come in three thicknesses, the thinnest being Type I, which is typically used for RAM or ROM memory. Type II cards, which are slightly thicker, may contain, for example, a fax/modem, while Type III cards are thick enough to contain a hard disk drive.

PCMCIA (Personal Computer Memory Card International Association)—The organization responsible for the development of the PC Card standard.

Peaking—A type of EQ circuit used to cut and boost a band of frequencies, producing

a mountain-peak type response. The width of the band is called the Q. Middle-band EQ is usually of the peaking type. Compare with Shelving.

PEQ—Abbreviation for “parametric EQ.” Program—Measured impulse response data is combined with variable parameters

such as reverb time and initial delay to form reverb programs. Preset programs are supplied on CD-ROM. User programs can be stored in the Quick memories, Internal Card or PC Card.

Program Change—A type of MIDI message for recalling programs. Project—A Project contains all the Quick memory programs and the current pro-

gram settings. Projects can be stored on the Internal Card or PC Card. Q—The unit used to express a ﬁlter’s width. High values imply a narrow frequency

band, low values, a wide frequency band. Quick memory—Quick memories are special memories for storing programs.

Unlike programs stored on the Internal Card, PC Card, or CD-ROM, which take time to load, Quick memory programs can be recalled instantly.

Reverb mode—The SREV1 offers three modes of operation: 2-channel, 4-channel, and 2-channel x2. In 2-channel mode, the SREV1 functions as a stereo processor. In 4-channel mode, the SREV1 offers 4-channel surround processing. In 2-channel x2 mode, the SREV1 functions as two independent stereo processors (A and B).

Reverb time—The time it takes the reverberation to decay by –60 dB. See also Con- volution time.

RS-232C—An interface for connecting serial devices, offering a transmission distance of approximately 15 meters, typically using 9- or 25-pin D-Sub connectors.

RS-422—A balanced interface for connecting serial devices, offering a transmission distance of approximately 1 kilometer, higher data rates, and greater immunity to interference than RS-232C.

Shelving—A type of EQ circuit used to cut and boost frequencies above or below a set frequency. It produces a shelf-looking response curve. High and low EQs are usually of the shelving type. Contrast with Peaking.

SREV1—Owner’s Manual

Tascam TDIF-1 interconnect format—The Tascam Digital InterFace audio inter- connect format typically found on Tascam TDIF-1-compatible digital audio equipment. TDIF-1 is a bidirectional, 8-channel format, which uses 25-pin D-sub connectors.

Wordclock—A clock signal used to synchronize the data processing circuits of devices digital audio equipment.

YGDAI (Yamaha General Digital Audio Interface)—Yamaha digital audio interface system offering a range of analog and digital input and output options for Yamaha digital audio equipment, including AES/EBU, ADAT, and Tascam DIO.
