The A-D and D-A converters all support 24-bit word lengths and are 96kHz capable, with 128 times oversampling for the 44.1kHz and 48kHz base sample rates and 64 times oversampling for the 88.2kHz and 96kHz rates. For the record, the maximum input and output level when operating in the +4dBu mode is a huge +24dBu - enough for any digital recorder. All of which means that this Yamaha device is slightly more sensitive than most when configured to accept semi-professional signals. Rear-panel slide switches enable the I/Os to be independently configured for +4dBu or -10dBu nominal levels - and it might be worth clarifying (for those who fret about such things) that -10dBu (245mV) is roughly 2.5dB lower than the more usual -10dBV (316mV) reference level. The analogue interfacing comprises both XLRs and TRS quarter-inch sockets, wired in parallel and accommodating balanced line-level inputs and outputs. The only minor disappointment is that an S/PDIF interface isn't included as well - although if necessary it is fairly easy to convert electrical characteristics from one to the other with a suitable 'bodge lead' or in-line transformer. AES-EBU digital input and output sockets are provided, along with a word-clock input for synchronisation within a digital studio environment.
In line with Yamaha's new range of digital consoles, the SPX2000 has been equipped with digital interfacing facilities.
REVERB REFLECTION GRAPH SOFTWARE
When complete, the editor software will be available for download from the SPX2000 section at Digital & Analogue Interfacing When it is finally launched, it will also apparently allow management and archiving of user presets - including allowing groups of presets to be downloaded to the SPX2000 for specific projects or performances, for example. This editor software was scheduled for release in December 2003, but when December arrived its release was put back to March 2004.

The front-panel styling and control layout are similar to the very first generations of SPX machines, and the data wheel of the SPX990 has been removed to provide space for a few new buttons - the revision improving the ergonomics and usability, to my way of thinking, as well as accommodating some new features.Ī rear-panel USB socket allows the SPX2000 to be connected to a computer for graphical editing via a forthcoming software interface. The new unit also features a dark-blue brushed-metal finish instead of the all-black control panels of previous models. The SPX2000 retains the 1U rackmount case format, although it is a little deeper than most of the other models at 363mm from the rack ears to the rear-panel connectors. There are 122 factory presets provided, and the new machine features much improved interconnectivity, as well as 96kHz sample rate operation. The new machine has a familiar-looking user interface too, along with Yamaha's latest high-quality effects DSP, which powers the new REVX reverb and updated effects algorithms. The latest product to bear the SPX moniker is Yamaha's new SPX2000, providing the same broad range of facilities as the previous SPX generations. Not surprisingly, large numbers of all of these units are still in daily use around the world, and there can be very few studios that don't have an SPX unit somewhere in the rack. This original processor was subsequently upgraded to MkII status before being superseded by the SPX900, SPX1000 and the current SPX990. This classic multi-effects processor provided a quality of stereo digital reverb which was quite amazing for both the time and the price, and the array of other time-delay effects - phasing, flanging, chorus, delays, echoes and pitch-shifters - were equally impressive and very usable.

The introduction of Yamaha's original SPX90 in the late '80s was nothing short of revolutionary for home and professional studios alike. One of Yamaha's most well-known studio products gets a makeover for the 21st Century.
