Congratulations on your acquisition of a Yamaha SPX50D Digital Sound Processor! The SPX50D is a remarkably versatile digital sound processor that can be used by guitarists, keyboard players, home recording enthusiasts, mixing engineers — anyone involved with
music. It offers a selection of 50 top-quality effects including digital reverberation, gated
reverb, echo, flange, phase and a group of superb distortion effects. The distortion effects actually combine distortion with other effects (reverb, flange, etc.) for extraordinary sound processing versatility. In addition to the 50 preprogrammed memory locations, there are 50 “user memory locations” which can be used to store your own edited versions of the preset effect programs, so you can recall your own effect creations anytime they are necessary. There's even an INSERT loop that allows you to switch a second signal processor unit into and out of the SPX50D signal path by simply pressing a button. The SPX50D is also MIDI
compatible so you can select effects via remote MIDI control.
In order to fully take advantage of all the capability offered by the SPX50D, we urge you to read this operation manual thoroughly. . ,

Keep the unit away from locations where it is likely to be exposed to high temperatures or humidity — such as near radiators, stoves, etc. Also avoid locations which are subject to excessive dust accumulation or vibration which could cause mechanical damage.
Strong physical shocks to the unit can cause damage. Handle it with care.
This product contains no user-serviceable parts. Refer all maintenance to qualified Yamaha service personnel. Open ing the case and/or tampering with the internal circuitry will void the warranty.
Always turn the power OFF prior to connecting or discon necting cables. This is important to prevent damage to the unit itself as well as other connected equipment.
Always plug and unplug cables — including the AC cord — by gripping the connector, not the cord.
Never use solvents such as benzine or thinner to clean the unit. Wipe clean with a soft, dry cloth.
Make sure that the power supply voltage specified on the rear panel matches your local AC mains supply.
Since the SPX50D contains digital circuitry, it may cause interference and noise if placed too close to TV sets, radios or similar equipment. If such a problem does occur, move the SPX50D further away from the affected equipment.
The SPX50D contains a long-life lithium battery which main tains the contents of the buffer and user memory locations even when the unit is turned OFF. With normal use the battery should last for approximately 5 years. If the battery voltage falls below the safe level, however, the "*** WARN ING *** LOW BATTERY” display will appear on the LCD when the power is first turned ON. If this occurs, have the battery replaced by a qualified Yamaha service center. Do not attempt to replace the battery yourself!
/THE FRONT PANEL /
Press the POWER switch once to turn power ON, a second time to turn power OFF
This control should be used in conjunction with the INPUT LEVEL meter (see below) to set the optimum input level for the source used.
The input level meter consists of seven LEDs corresponding to -30 dB, -20 dB, -15 dB. -10 dB -6 dB. -3 dB and 0 dB Input level. When the source (instrument or other) is connected to the SPXSOD’s inputs, it should be played at the loudest level It will be played during actual use and the INPUT LEVEL control adjusted so that the maximum reading is about -3 dB.
This 2-digit numeric display shows the number of the' cur rently selected memory location (1 — 00). When the LED display Is continuously lit the effect corresponding to the number displayed is active. When the LED display Is flash ing, this indicates that a new memory location has been selected but has not yet been recalled, leaving the previ ously selected effect active.
This 16-character x 2-line liquid crystal display panel nor mally displays the title of the selected effect on the top line and a selected parameter and Its value on the bottom line. One or both lines may also be used to display error mes sages or warnings.
This button is pressed to access the various parameters which can be edited within each effect. Each press on the PARAMETER button selects the next parameter on the "list” for the selected effect. When the parameter mode Is se lected, the parameter button LED will light.
These buttons are used to select memory locations when the memory selection mode is active (after the MEMORY button has been pressed), or to change parameter values when parameters are selected for editing (after the PARAMETER button has been pressed). The A and V buttons are also used to program several UTILITY functions.
This button is used to store edited effect parameters into one of the user memory locations between 51 and 00.
When a new memory location number has been selected using the A and V buttons, the RECALL button must be pressed to activate the selected effect.
The COMPARE button Is used In the PARAMETER mode to compare the sound of an edited parameter with that of the parameter before it was changed. When the COMPARE button is pressed, the pre-edit parameter value is temporarily recalled and the COMPARE button LED will light. Press the COMPARE button again to return to the edited parameter value.
@ MEMORY Button |
0 INSERT Button |
Pressing this button engages the memory selection mode, allowing a new memory location to be selected using the and V buttons. When the memory mode is selected, the memory button LED will light.
The INSERT button activates the SPX50D INSERT IN/OUT loop, adding a second signal processor connected to the INSERT IN and OUT jacks to the effect chain. The INSERT ON/OFF status for each memory location can be memorized and recalled whenever that memory location Is selected. The INSERT loop is active when the INSERT button LED Is lit.
® UTILITY Button |
® BYPASS Button |
This button accesses a list of utility functions allowing editing of effect titles, MIDI control programming and increment footswitch recall range programming.
Direct Recall Buttons (REV/DLY Group, MOD & OTHERS,
DIST Group)
These buttons provide fast direct access to the SPXSOD’s three major effect groups.
When the TRIGGER button is pressed and its LED indicator is lit, a footswitch plugged into the rear-panel MEM./TRG. FOOT SW jack can be used to trigger three of the SPXSOD’s effects: ADR-Noise Gate, Reverb & Gate, and Triggered Pan. Press the TRIGGER button a second time to restore the foot switch’s normal memory selection function.
The BYPASS button switches the selected effect ON or OFF, leaving the direct signal only when BYPASS is active.
The TUNER OUT jack can be connected directly to an elec tronic guitar tuner allowing convenient tuning without the need to unplug your instrument from the SPX50D input and connect it to the tuner.
Your instrument or other audio-signal source can be con nected here or to the duplicate INPUT jack provided on the rear panel. The front-panel INPUT jack takes priority, so if sources are plugged into both the frontand rear-panel IN PUTS, only the front-panel INPUT will be active. The INPUT accepts a mono 1/4” phone plug, and is unbalanced.
/THE CONNECTOR PANEL?
O MIDI IN Connector
MIDI signals from external MIDI devices can be fed to this terminal to remotely select effects, set the pitch shift of the PITCH CHANGE A effect, and trigger some other effects.

Each of the SPX50D effects has a number of internal parame ters which may be edited by you to create a sound that is ideally suited to your own specific musical requirements. A complete description of each effect and its parameters is given in “3. DESCRIPTIONS OF THE EFFECTS & THEIR PARAME TERS” ON PAGE 13. Using effect 01 (REV 1 HALL) as an example, here’s how to access and edit effect parameters;
®Select and recall the effect to be edited (REV 1 HALL for this example).
@Press the PARAMETER button and the first of the selected effect’s parameters will appear on the bottom line of the LCD. Each time the PARAMETER button is pressed, the next parameter on the selected effect’s “parameter list” will be called. With REV 1 HALL, for example, the following parameters are called in sequence:
Note that the first parameter in the list is returned to if the PARAMETER button is pressed after the last parameter (OUT LVL in this example) has been called.
Once the desired parameter has been called, its value is edited by using the A and/or V buttons. The A button increases (increments) the value while the V button de creases (decrements) the value. Either button can be held down for continuous incrementing or decrementing.
New value
In this way you can go through and edit any number of the parameters to create the sound you want. If, however, you select and recall a new effect without first storing your ed ited parameters in a memory location between 51 and 00, any changes you have made will be lost and will have to be re-programmed. If you want to keep an edited effect, use the STORE operation described beiow.

3:DESCRIPTIONS OF THE EFFECT PROGRAMS
&THEIR PARAMETERS
/THE BALANCE AND OUTPUT / |
|
/ LEVEL PARAMETERS |
/ |
Since all of the SPX50D effects have the same BALANCE and OUT LVL (Output Level) parameters, we’ll describe them here and leave them out of the descriptions of each effect that follow. BALANCE and OUT LVL are normally the last two para meters called in an effect’s parameter list.
Effect/Direct Signal Balance (BALANCE): 0 — 100% This parameter adjusts the balance between the direct
sound of your instrument (or other source) and the effect signal. At 100% only the effect sound is delivered from the SPX50D outputs, while at 0% only the direct sound is output. At a setting of 50%, the direct and effect sounds are output in approximately equal proportions.
Effect Output Level (OUT LVL): 0 —100%
This parameter sets the output level of the effect. This is particularly handy for matching the levels between effects when setting up an effect sequence for a live performance.

Reverberation is the warm musical “ambience" you experience when listening to music in a hall or other properly-designed acoustic environment. The SPX50D offers ten different reverb effects, simulating types of reverberation you would experience in various halls (1 — 3), in smaller rooms (4 — 5), reverb effects ideally suited to vocals (6 — 8), and the type of reverberation produced artificially by a plate reverberator (9 — 10).

Modulation Frequency (MOD. FRQ): 0.1 Hz — 20 Hz
Sets the speed of modulation, and hence the rate at which the effect varies.
Modulation Depth (MOD. DEPTH): 0% —100%
Sets the amount of delay time variation, thus adjusting the depth of the effect.
Left Channel Delay (Lch DLY): 0.1 — 250 milliseconds
After the delay set by this parameter, the first left-channel echo will appear, Subsequent echoes will appear at the same time interval, the number of echoes depending on the setting of the feedback gain setting for the corresponding channel.
Left Channel Feedback Gain (Lch F.B): -99% — -F99% Adjusts the number of echoes that follow the direct signal - from zero to a virtually infinite number of echoes at the maximum setting.
Right Channel Delay (Rch DLY): 0.1 — 250 milliseconds Same as Left Channel Delay, but affects the right channel only.
Right Channel Feedback Gain (Rch F.B): -99% — .f99% Same as Left Channel Feedback Gain, but affects the right channel only.
High Frequency Feedback (HIGH): x0.1 —x1.0
Controls feedback in the high-frequency range. The highfrequency feedback is reduced as the value of this parame ter is decreasxed.
Modulation Delay (MOD. PLY): 0.1 —100 milliseconds
This sets the basic delay time from the initial direct sound to the beginning of the flange effect.
Feedback Gain (F.B. GAIN): 0% — 99%
Determines the amount of flange signal which is fed back to the input of the processor for further modulation. More feed back increases the overall complexity, “strength” and decay time of the effect.

22.Chorus A
Like flanging, chorus serves to thicken the sound of an instru ment, creating the effect of several instruments playing at once. The A and B chorus effects split the incoming signal into three signals placed at the center left and right of the stereo image. The delay time and level of the three signals are then modulated by the LFO (Low Frequency Oscillator). The Chorus C effect sends the direct sound to the left channel and the processed sound to the right channel.

28. ADR-Noise Gate
This program uses a “gate” to pass or shut off the input signal in a number of ways. It can be used to pass just a short seg ment of a longer input signal, or it can be set up to pass only signals that exceed a specified level. In the latter case this program functions as a “noise gate.” It is also possible to cre ate reverse gate type effects in which the gain increases gradually after the effect is triggered.
100%
Hold Time (HOLD): 1 — 30,000 milliseconds
Determines how long the gate stays open, allowing the sig nal to pass at the DECAY LEVEL, after the first decay and prior to beginning of the RELEASE TIME.
Release Time (RELEASE): 5 — 32,000 milliseconds Determines how long it takes for the gate to close fully after the HOLD TIME has ended.
MIDI Trigger (MIDI TRG.): OFF, ON
When this parameter is turned ON, a KEY ON EVENT mes sage .from an external MIDI keyboard can be used to trigger the gate. A KEY ON EVENT message is transmitted when ever a note on a MIDI keyboard is played.

the footswitch trigger function).
Trigger Delay (TRG. PLY): -100 — +100 milliseconds Produces a delay between the time at which the gate is
triggered and that at which it actually opens. If a minus value is programmed, the input signal is delayed so that, effec tively, the gate opens before the signal appears.
Trigger Mask (TRG. MSK): 5 — 32,000 milliseconds
This parameter makes it impossible to re-trigger the gate function until the programmed time has elapsed.
Attack Time (ATTACK): 5 — 32,000 milliseconds
Determines how long it takes for the gate to open fully from the time it begins to open.
Decay Time (DECAY): 5 — 32,000 milliseconds
Determines the length of time it takes for the gate envelope to fall to DECAY LEVEL after it is fully open.
Decay Level (DECAY LVL): 0 — 100%

|
of a signal to prevent overloading certain types of amplification |
|
of recording equipment. |
|
Attack Time (ATTACK): 1 — 40 milliseconds |
|
Determines how long it takes for full compression to be |
|
reached after the effect is triggered (i.e. the THRESHOLD |
|
level is exceeded). The right ATTACK setting is essential to |
|
preserve the natural initial attack sound of the instrument |
|
used — or modify it as desired. |
|
Release Time (RELEASE): 10 — 2,000 milliseconds |
|
Determines how long it takes for compression to be released |
|
after the input signal drops below the THRESHOLD level. |
|
The RELEASE setting is important to preserve the natural |
|
release sound of the instrument used. Too short a RE |
|
LEASE setting will cause the sound to be cut off unnaturally. |
|
Threshold Level (THRESHOLD): -48 — -6 dB |
|
Determines the level of the input signal at which the com |
|
pression effect begins. Set at a low level (-48 dB) all input |
|
signals will be compressed. At a higher level, only those |
|
signals exceeding the THRESHOLD level will be com |
|
pressed, thus producing a limiting effect. The THRESHOLD |
|
level must be set to match the level and characteristics of |
|
the instrument being used, as well as the desired effect. |
|
Compression Ratio (RATIO): 1 — 20 |
|
This parameter sets the "amount” of compression applied to |
|
the input signal. A setting of 1.0 produces no compression, |
|
while a setting of 20 produces maximum compression. |
|
Detect Delay (PET. PLY): -50 — +50 milliseconds |
|
This parameter sets an initial delay between the time the |
|
input signal begins (the time the THRESHOLD level is ex |
|
ceeded) and the time the compression effect begins. This |
|
delay can be used to allow the initial attack of an instrument |
|
to come through completely unaffected while the rest of the |
|
signal is compressed. A minus DET DLY setting causes the |
|
compressed sound to appear before the direct instrument |
|
sound. |

30. Reverb & Gate
This effect combines a reverb program with a gate program, making it possibie to output only a segment of a ionger reverb sound.
-(TIME)
Release Time (RELEASE): 5 — 32,000 milliseconds
This parameter determines the time it takes for the gate to close completely after the HOLD time has elapsed.
MIDI Trigger (MIDI TRG.): OFF, ON
When ON, a KEY ON EVENT message from a MIDI key board can be used to trigger the effect.
NOTE; This effect can also be triggered by a footswitch plugged into the rear-panel MEM./TRG. FOOT SW jack if the front-panel TRIGGER button LED is lit (press the TRIGGER utton to activate or de-activate thei footswitch trigger function).
Reverb Time (REV TIME): 0.3 — 99 seconds
The length of time it takes for the level of reverberation at 1 kHz to decrease by 60 dB.
High Frequency Reverb Time Ratio (HIGH): x0.1 — xO.1 This parameter allows alteration of the high-frequency reverb time in reiation to the overall reverb time.
Initial Delay (DELAY): 0.1 — 50 milliseconds
This parameter represents the delay between the direct sound of an instrument and the first of the many reflections that together form reverberation.
High-pass Filter (HPF): THRU, 32 Hz —1000 Hz
Permits roiiing off the the low-frequency content of the reverb signal below the set frequency. The HPF is OFF when set to THRU.
Low-pass Filter (LPF): 1 kHz — 11 kHz, THRU
Permits roiiing off the high-frequency content of the reverb signal above the set frequency. The LPF is OFF when set to THRU.
Trigger Level (TRG. LEVEL): 1 — 100
Determines the amplitude of the input signal required to trig ger opening of the gate. At 100 only high-level input signáis will trigger the gate, whiie at 1 even the siightest input signai wiii trigger the gate.
Hold Time (HOLD): 1 — 30,000 milliseconds
This parameter sets the amount of time the gate is “open,” aiiowing the reverb sound to come through.
31. Pitch A
This program can actually change the pitch of an input signal over a 2-octave range. The shifted pitch can be combined with the direct sound (by an appropriate setting of the BALANCE parameter) to create automatic harmonies.
Pitch Shift (PITCH): -12 — +12
Sets the degree of pitch change in semitone steps. +12 cor responds to an output pitch one octave higher than the input pitch, and -12 produces an output pitch one octave lower than the input pitch. An external MIDI keyboard can even be used to select the desired degree of pitch shift.
Fine Tuning (FINE): -100 — +100
Permits extremely fine pitch adjustment in one-cent steps.
Delay Time (DELAY): 0.1 — 400 milliseconds
Sets the delay between the direct sound (input signal) and the pitch-shifted output signal.
Feedback Gain (F.B. GAIN): 0 — 99%
When this parameter is set to 0, only a single pitch-shifted sound is produced after the DELAY time has elapsed. As the value of this parameter is increased, however, more and more delayed repeats are produced, each pitch-shifted up or down from the previous repeat according to the setting of the PITCH parameter.
19
Base Key (BASE KEY): OFF, C1 — C6
This parameter sets the “BASE KEY” for an external MIDI synthesizer used to control the PITCH parameter (the MIDI OUT terminal of the synthesizer must be connected to the SPX50D MIDI IN terminal, and the SPX50D must be set to receive on the MIDI channel on which the synthesizer is transmitting). If, for example, the BASE KEY parameter is set to C4, pressing the C3 key on the synthesizer (C3 is one octave lower than C4) will set the pitch change value to -12. Pressing D4 on the keyboard would produce a pitch in crease of one whole-tone (+2). If a key more than an octave higher or lower than the BASE KEY is pressed, the resultant pitch change setting will still be within the -12 to +12 range, as shown in the illustration below. If the BASE KEY parame ter is set OFF, pitch cannot be controlled via the MIDI IN terminal.

PITCH CHANGE B makes it possible to produce two independ ently pitch-shifted output notes in addition to the direct signal, so you can actually create three-part harmonies with a single input note. Both pitch-shifted notes appear at the center of the stereo sound field (i.e. they are output equally to the L and R OUTPUT jacks).

NOTE: The program number/memory number assignments made are stored in the BANK selected in the previous MIDI CONTROL function. To program the program change/memory number assignments for a different BANK, return to the MIDI CONTROL mode, select the desired BANK, then program the required assign ments.
The SPX50D permits memory selection via an optional Yamaha FC4 or FC5 footswitch connected to the rear-panel MEMORY footswitch jack. The fourth function accessed by the UTILITY button — F.SW MEMORY RCL — permits setting the range of memory location numbers that will be selected when the footswitch is pressed.
F . S W MEMORY RCL

55 |
If, for example, the RANGE parameter is set to “51 TO 55” as shown in the LCD illustration above, each time the footswitch is pressed the next highest memory location will be selected until the last number in the specified range is reached. After the last number in the specified range, the first (lowest) number is se lected and the process repeated. Reverse sequences can be programmed by entering the highest number in the range be fore the lowest, as shown below.
