The Yamaha SPX90 is an amalgam of advanced acoustical research and digital technology designed to provide home recording enthusiasts a wide range of effects.
The Yamaha SPX1000 is a highly sophisticated digital reverberation and effects system which offers 40 preset effect programs including accurate simulations of natural reverberation and early-reﬂections, delay and echo effects, gated effects, modulation effects, a versatile compressor, a low-level expander, a harmonic exciter, multiple effects which function as several Yamaha SPX1000 units in one, independent 2-channel effects, freeze (sampling) programs and others.
With a sampling frequency of 44.1 kHz, it delivers full, flat frequency response from 20Hz to 20kHz for exceptionally clean, “transparent” effect sound, and direct digital interfacing capability makes it compatible with the most up-to-date sound systems.
The preset effect programs can be edited, re-titled, and stored in any of 59 RAM user memory locations. Individual two-band parametric EQ and dynamic ﬁlter parameters are provided for each effect program for precise tonal tailoring.
In addition to the basic effect and EQ parameters, the SPX1000 offers a list of “internal parameters” which provide exacting control over the effect sound. The SPX1000 is also MIDI compatible, with a MIDI IN terminal that allows MIDI selection of effect programs, and a switchable MIDI THRU/OUT terminal. When switched to OUT, edited programs stored in internal RAM can be dumped to a MIDI data recorder or other data storage device. Programs thus stored can be reloaded when necessary via the MIDI IN terminal.
As an extra touch of convenience the Yamaha SPX1000’s analog input and output terminals can be switched to match -20 dBm or +4 dBm line levels + providing compatibility with a broader range of sound equipment.
I own 7 Yamaha reverb processors SPX90, 90II, 900, 990, 1000, Rev5, Rev7. The SPX1000 has the most natural sounding reverb of them all, as well as being stereo in and out. Honestly if you want natural sounding reverb buy one they are a bargain.
