SREV1—Owner’s Manual
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 elec-
trical 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 per-
formance 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 con-
dition 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 inter-
nal 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.
ii
Important Information
SREV1—Owner’s Manual
• 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
Owner’s Manual.
• 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 acclima-
tize for about one hour before use.
• 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.

SREV1—Owner’s Manual
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. Fin-
gerprints, 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 accli-
matize 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.

erences to physical buttons are enclosed in square brackets, such as “press the [ENTER]
button.” References to page buttons are not emphasized, for example, select the WCLK
IN button.
Generally there are three versions of each RC-SREV1 display page, one for each mode:
2-channel, 4-channel, and 2-channel x2. If relevant to the task being explained, all three
pages are shown. If the item being discussed is the same regardless of which mode is
selected, then only one page is shown.
“PC” refers to an IBM PC-compatible computer running a Windows operating system.

SREV1—Owner’s Manual
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 process-
ing 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.
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 sec-
onds per channel (4-channel or 2-channel x2 mode). Featuring an additional 32 con-
volution 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

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 set-
tings, 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 pro-
grams 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 individu-
ally, 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/ste-
reo 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 word-
clock 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.
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 char-
acteristics) 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 pro-
grams are for use with 2-channel mode and 2-channel x2 mode, while 4-channel pro-
grams 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 pro-
grams 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 Pro-
gram pages. See “Working with Quick Memories” on page 42 for more information.

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.

File Types
The SREV1 uses several file extensions to identify file types. Although these extensions
do not generally appear on the RC-SREV1 pages, they may come in useful when check-
ing the contents of a PC Card or CD-ROM on your PC.
Parameters
SREV1 program parameters, such as reverb time, initial delay, an EQ, are stored within
each program. Saved parameters include: reverb time, initial delay, reverb balance,
reverb level, pre EQ, post EQ, and impulse-response data names.
Other parameters, including reverb mode, wordclock source, I/O select, I/O level, and
MIDI settings, are not stored within each program, but they are stored in the SREV1’s
battery-backed memory.
