SPX990 FEATURES • 20 bit AID and DIA conversion for high quality sound. • pre/post-effects in a high quality Multi-effect system. • with memory card slot, XLR-type connectors and phone jacks • convenient operations using function keys, data entry dial and large LCD display panel. Congratulations on your acquisition of a Yamaha SPX990 Professional Multi-effect Processor. The SPX990 offers 80 preset effect programs including accurate simulations of natural reverberation and early reflections, delay and echo effects, modulation effects, pitch change effects, complex effects, freeze (sampling) programs which can do loop playback and much more. Epoch-making new effects like the main effect programs include multi-tap delay for accurate definition of time and pan of several delays, round pan and intelligent pitch which can add harmony through internal recording on specific keys and scales. The temp, mono echo, temp, stereo echo, and temp, quad echo effects also add new attractive features to the SPX990. With a sampling frequency of 44.1kHz, it delivers a full, flat frequency response from 20Hz to 20kHz for exceptionally clean, "transparent" effect sounds and direct digital interfacing capabilities making it compatible with the most up-to-date sound systems. The preset effect programs can be edited, re-titled and stored in any of the 100 RAM memory locations. Convenient external data storage is provided by a memory card slot that accepts optional RAM cards for storage effect programs. The 3-band parametric EQ, compressor, Aural Exciter®, or distortion can be used in the pre-effect program for precise tonal tailoring. The 3-band parametric EQ, compressor, or Aural Exciter® can also be used in the post-effect program. The SPX990 is also MIDI compatible, with a MIDI IN terminal that allows MIDI selection of effect programs and a switchable MIDI THRUIOUT terminal. When switched to OUT, edited programs stored in the internal RAM memory can be dumped to a MIDI data recorder or other data storage devices. Programs thus stored can be reloaded when necessary via the MIDI IN terminal. As an extra touch of convenience, the SPX990>s analog input and output terminals can be switched to match -20dBm or +4dBm line levels, providing compatibility with a broader range of sound equipment. In order to fully take advantage of all the capability offered by the SPX990 Professional Multieffect Processor, we urge you to read this operation manual thoroughly while trying out the many features and effects provided by the SPX990.
