AES: Yamaha Sampling Reverb Takes You There

Ahem - 'Proprietary Convolution Sampling Technology Offers Levels Of Sonic Realism'      12/05/01
It may seem like just another black box, but it's demure looks house a new high-end digital sampling effects system that is the flagship unit to Yamaha's range of signal processors. Essentially it's a high-end multi-channel reverb processor with the ability to sample acoustic spaces and apply them to the signal of your choice. The SREV1 operates in 2-channel (up to 5.46 sec/channel), 4-Channel (up to 2.73 sec/channel) or 2-Channel x 2 (up to 5.46 sec/channel for each processor) modes. The SREV1 uses proprietary Convolution sampling technology that uses impulse response samples of actual acoustic environments, rather than the generated algorithms found on other reverb products on the market. By using a time stretched pulse (TSP) to measure impulse response via bundled PC software, one, two or four channels may be measured to capture and create custom reverb. A selection of editable reverb programmes on the SREV1 simulates environments ranging from room ambiences to stadiums, with each offering control of pre-EQ, post-EQ and reverb parameters. The unit operates in 2-channel (up to 5.46 sec/channel), 4-Channel (up to 2.73 sec/channel) or 2-Channel x 2 (up to 5.46 sec/channel for each processor) modes. With the addition to the DSP expansion board, reverb time in each mode is doubled, producing reverbs of up to 10.92 seconds. The system includes the SREV (24-bit / 48kHz 3U rack-mount mainframe), RC-SREV1 remote controller and DB-SREV1 DSP Expansion Board and is immediately available. The SREV1 contains MIDI IN/OUT/THRU, two mini YGDAI card slots, two AES/EBU input/outputs, two TO HOST serial ports and external word clock input. Storage options include a CD-ROM drive for loading data and upgrades, plus a PCMCIA card slot. The unit is expected to retail at around £3800 (+/-$6000) – significantly less than the SONY DRES777, it’s closest relative.
