Professional Multi-Effect Processor
The new generation SPX with 24bit/96kHz audio
and new "REV-X" reverb algorithm.

Delivery: August 2003

The name "SPX" has been synonymous with "professional multi-effect processor" for more than 15 years, and the models like SPX90, SPX90II, SPX900, SPX1000 and SPX990 have been the most commonly found equipment in the studio and SR racks.The SPX2000, while inheriting the standard interface and common programs from its predecessors, has the new "REV-X" reverb algorithm and the 96kHz audio DSP. It also offers advanced user interface like 5 assignable LCD back colors, operation lock mode and computer based editor program.
SPX2000 is the new generation equipment in line with the DM series Digital Production Consoles, and is suitable for broad range of applications, from Live SR to production studios where professional quality effect processing is required.
The SPX2000 hardware is the 96kHz audio DSP, with 32-bit internal processing (58-bit accumulator) which offers abundant processing power for the advanced effect algorithms. The 24-bit 128-times over-sampling AD/DA converters deliver 106dB dynamic range and flat response from 20Hz to 40kHz at 96kHz sampling rate. Both are in line with the DM series Digital Production Console quality.

Refined Preset Programs Including the Newly Developed "REV-X" Reverb Algorithm
There are 3 banks to the SPX2000 memory: "PRESET", "CLASSIC" and "USER". "PRESET" bank contains 97 programs. 17 programs are made with the newly developed "REV-X" reverb algorithms. "REV-X" is a whole new generation of Yamaha Reverb programs with the rich reverberation tone and smoothest decay. There are "REV-X Hall", "REV-X ROOM" and "REV-X PLATE" algorithms. Newly introduced parameters like ROOM SIZE and DECAY envelope . Other 80 presets consist of the popular trademark SPX programs such as gate reverbs, delays, pitch effects, modulation and other special effects. All programs went through refined editing by the top engineers, and no program is the same as the ones offered in the previous effect processors or digital consoles. The "CLASSIC" bank on the other hand consists of 25 programs giving you the reminiscence of the original SPX90 presets. "USER" bank can store 99 user programs.

Front Panel User Interface with Colors
SPX2000 hardware cosmetic is designed to offer optimum reliability for the engineers on site. The rugged aluminum front panel features 2 sets of "Cross-keys" - simple navigation tool anyone is familiar with. Parameters are sorted in 3 groups; "PARAMETER","FINE PARAM" and "UTILITY" to ensure speedy access. Also other dedicated buttons like UNDO, COMPARE, BANK, MODE, METER, TAP, and BYPASS ensure efficient operations. SPX2000 LCD offers 5 back light color variations. You can freely assign any of the 5 colors to user programs. The preset programs are colored by effect groups giving you an instant recognition of the effect type even from the distance. (CYAN: Reverbs, WHITE: Delays, MAGENTA: Pitch & Modulations, YELLOW: Others, GREEN: CLASSIC Bank) RED is reserved for warning messages. SPX2000 "OPERATION LOCK" function offers 3 security levels; from preventing accidental changing of Utility settings, or protecting stored memories to prohibiting almost all operations.

Professional Audio I/O and Control Connectors
SPX2000 Rear Panel houses, for analog connection, XLR type (w/latch) and quarter inch L + R INPUT and OUTPUT connectors both with +4dBU/-10dBu selector switch. Professional digital connection is secured with AES/EBU XLR type I/O connectors and BNC WORDCLOCK IN connector. Also MIDI IN, OUT/TROUGH and USB TO HOST connectors are provided for remote control and data management using computers, Digital Consoles or any MIDI device. Foot Switch connector for effect tempo control is placed on the front panel.

"SPX2000 Editor" for Mac
OSX and Windows
SPX2000 Editor will give you the editing, data management, and remote control capability using computers, in the same environment and common interface as the STUDIO MANAGER for Yamaha Digital Consoles. "SPX2000 Editor" is scheduled for release in
December 2003. (To be offered to SPX2000 users by web download from yamaha)
