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
