The SM-FX500 Ultima Professional Mixing Desk
The new SM-FX500 Ultima is a 4-Channel 19” Rack mixer with a built-in DSP. Its compact 5U design houses
features that you would normally only find in much higher priced units. Designed with both small installations
and mobile DJ’s in mind it also has a few little extras to protect your system and maintain a high quality sound
The SM-FX500 Ultima has 3 microphone inputs, two of which are controlled with the dedicated Mic channel and
one assigned to the 4th channel as a switchable option. Mic’s 1 & 2 share a 3-band EQ and Mic override system.
Each of the 4 music channels has an individual gain control and 3-band EQ offering +10dB of Boost and –30dB
of Kill. Each channel is also easily assignable to the crossfader A or B.
The unit has a built in digital signal processor offering 8 effects which are assignable to each music channel,
microphone channel, master or crossfade A or B. The effects are linked to the mixers built in BPM counter to
allow the DJ to ‘Beat-Sync’ the effects at the touch of a button, Alternatively the effects can be manually
adjusted using the independent parameter time control and the parameter ratio control. The SM-FX500 Ultima
also has effects specifically for the crossfade, when selected 3 different effects can be activated and controlled
by moving the crossfade from A-B using the effects to mix from one channel to the next.
The crossfade on the SM-FX500 Ultima is VCA controlled as well as being able to assign effects the user can
adjust the curve of the fader from a smooth mix to sharp mix. It also has fader start, this will start a compatible
CD-Player and also stop it return it to the Cue point, this can be a very creative tool when combined with the
The SM-FX500 Ultima also has a few installer friendly options. The user can easily replace the channel faders
and crossfader by removing just a few screws. For the outputs there is a choice of balanced XLR or
Unbalanced Phono, the unit also offers a booth output, record output and digital output all recessed into the rear
of the unit. There is also a master trim level on the rear; this allows the installer to set the maximum output of
the mixer.

Important Safety Information
All the safety and operating instructions should be read before the appliance is operated.
To prevent fire or shock hazard, do not expose this appliance to rain or moisture.
To reduce the risk of electric shock, do not remove the cover (or back). There are no serviceable parts inside. Always
refer servicing to qualified service personnel.
Cautionary Notes:
Handle the power supply cord carefully. Do not damage or deform the power supply cord. If it is damaged or deformed,
it may cause electric shock or malfunction when used. When removing from wall outlet, be sure to remove by holding
the plug attachment and not by pulling the cord.
In order to prevent electric shock; do not open the top cover. If a problem occurs, contact your dealer.
Do not place metal objects or spill liquid inside the mixer. Electric shock or malfunction may result.
Any use of the controls, or any adjustment, or the performance of any procedure other than those specified herein may
result in serious damage to your health.
The mixer should not be opened or repaired by anyone except properly qualified service personnel.
Double insulated - when servicing, use only identical replacement parts.
In the event of ground - loop problems in the audio system, DO NOT disconnect the AC supply earth to any
equipment before consulting equipment instruction manuals. For example most power amplifiers have audio
ground lift switches, or are designed specifically to avoid ground - loop problems connected to ‘earthed’ mixers.
Ensure the mixer has a ‘clean’ AC supply from a wall socket that is not used for other equipment that would lead
to interference - such as lights, refrigerators etc.
The SM-FX500 Ultima is available in AC supply standard:
General Do’s & Don’ts
There are a few general Do’s and Don’ts thoughts that you should become familiar with if you have not had a
great deal of experience with professional audio systems.
Cables & Connectors - Always use good quality cables and connectors. It might seem expensive when you first
look at it, but the first time you have a problem in front of an audience you’ll curse the day you didn’t make that
small investment. Over 30 years in the business has taught us that over 75% of all problems with DJ systems
are simple connector ones. Don’t get caught out.
Switching on your system - Get into the habit of turning on the mixer and all the inputs to it before you turn on
the amplifiers. Play safe; always turn on your amplifiers last.
Power Supply - The power supply for your SM-FX500 Ultima is built into the mixer and will be fitted with a mains
plug specifically for the mains supply in your country. If it does not match the power socket you wish to use
check with your dealer before you plug it in. It is possible you could damage your mixer if it is not the correct
version for your mains power supply. Worse still, it could be unsafe. Don’t take chances with Mains Power - it
can kill.
Crossfader - The crossfader is the most used feature on your mixer and great care has been taken in the choice
of components for this function. Even so, it is the most likely thing to wear out first on your mixer, so we’ve made
it quick and easy to replace. Don’t get caught out, always carry a spare.

Crossfader Section
25. Crossfade Assign B
This button will assign the selected channel to the right hand side ‘B’ of the crossfade. The button will illuminate
blue when selected.
26. Crossfade Assign A
This button will assign the selected channel to the left hand side ‘A’ of the crossfade. The button will illuminate
blue when selected.
27. VCA X-Fade
This smooth action crossfader is VCA (Voltage Control Ampilfier) controlled this allows the user to adjust the
curve of fade from one side to the other.
Replacement of the Crossfader
When the crossfader has worn out it is very easy to replace. The SM-FX500 Ultima has been fitted with a quick
access panel, which can be changed in a matter of seconds, even while the mixer is in use. Follow these simple
1. Remove the crossfader panel using a Pozi-head screw driver
2. Lift out the removeable panel
3. Disconnect the crossfader assembly
4. Refit the connector to the new crossfader
5. Replace the panel and re-fit the screws
28. Fader Indicators
When the X-Fade effect switch (43) is in the ‘X-FADER’ or ‘AUTO’ position, these LED’s will light indicating
which side of the crossfade is supplying the output signal. As the crossfade is moved toward the opposite side
the LED will begin to flash, just before the music output changes to the opposite side the LED will flash quickly.
29. Fader Start Selector
This switch will allow a compatible CD-Player to be started using the crossfader. The control cables need to be
connected from (50) to the back of the CD-Player. If crossfade ‘A’ is switched on, when the fader is moved from
‘B’ to ‘A’ the CD will play, when the crossfader is moved back from ‘A’ to ‘B’ the CD will return to its Cue point.
Therefore moving the fader left to right quickly will give a stutter effect.
30. X-Fade Curve Control
This rotary knob controls the curve of the VCA crossfade. The Curve can be set from a smooth fade for mixing
to a sharp cut for scratching.
Selecting this symbol gives a sharp curve on the crossfade. With the crossfader in the ‘B’ position
moving the crossfade 2mm to the left will bring in the channel assigned to ‘A’ at full volume, this is ideal for
Selecting this symbol gives a fade without any drop in sound level. At the centre point both channel
will be a their full volume. There will be a slight increase in volume at the centre point as the two outputs
Selecting this symbol gives a fade with a drop in the music level of 2dB at the centre point the music
from the opposite channel will come in at this level also. This should give a mix with no increase in the master
volume if the gains from both channels are at an equal dB.
31. Power Switch
Use this switch to turn the power on/off to the mixer.
Note: Be sure to switch on the power to your mixer before the amplification system.

33. Effects ‘FX’ On/Off
Use this button to turn the main effects on (illuminated) of Off.
34. Effects Cue
This button gives a pre-fade indication of the selected effect in the headphones proir to the user switching the
effects on using the Effects ON/OFF button (33).
35. Effects Selector Switch
This switch is used to select the desired effect choose between:
Echo – This will give a delay-based effect in which copies of the music are heard trailing off to silence; similar to
shouting from a mountaintop and hearing your voice repeat.
Auto Pan – This will move the stereo sound automatically from the left to the right speaker repeatedly.
Flanger – This is an effect that generates a swirling sound by adding a slightly delayed copy of the signal in
which the copy's delay time fluctuates.
Manual Filter – The Filter effect removes certain frequencies from the music. Use the Time and Level/Depth
knobs to manually fade through the removal of each frequency.
Auto Filter - The Filter effect removes certain frequencies from the music automatically.
Reverb – This is an effect in which the ambience of a physical space is simulated.
Trans – This effect gives the impression of the sound dropping out, making it stutter.
Pitch Shift – This effect allows you to increase or decrease the pitch of the music without increasing or
decreasing the tempo.
36. Input Select Switch
This switch allows the user to select the input source for the effects to be added to.
37. Level/Depth Control
This rotary knob is used to adjust the ‘Y Parameter’ (mix ratio, resonance or feedback) of the selected effect.
38. Time Array Control
This rotary knob is used to adjust the ‘X Parameter’ (Time) of the selected effect.
39. LCD Display Screen
This screen gives the user a visual display of the selections that have been made within the DSP module.
Working from the top left hand corner it shows the input that is selected, the effect that is selected, the BPM of
the track playing, the ‘X Parameter’ and finally the ‘Y Parameter’.
40. Beat-Sync Select
These buttons are used to select which beat the effect will be on i.e. if the ½ button is selected the effects time
parameter will will match in time with the music every 2 beats.
X-Fade Effects Section
41. Echo Select
This button will assign an echo effect to the crossfade, so if the music assigned to X-Fade ‘B’ is playing moving
the x-fade to the left will take a sample of the music playing add an echo and fade it into the the music playing
on X-Fade ‘A’.
42. Platter Effect
This button will assign a platter effect to the crossfade, so if the music assigned to X-Fade ‘B’ is playing moving
the X-Fade to the feft will give the same effect as switching a turntable off as the fader is moved across the
musics pitch will drop.
43. Stutter Effect
This button will assing a stutter effect to the crossfade, so if the music assigned to X-Fade ‘B’ is playing moving
the x-fade to the left will take a sample and stutter it the more the X-Fade it moved to the left the faster the
stutter will become.
44. X-Fader Effects Select Switch
This switch is used to enable the X-Fade effects:
X-Fader – When the switch is in the X-Fader position the effects will be assigned to the crossfader as explained
in 41,42 & 43).
Off – this disables the X-Fader effects
Auto – This enables the X-fade effects to be activated in syncronisation with the Beat Sync Select buttons (40).
Assign the crossfade (e.g. CH1 – X-Fade A and CH4 – X-Fade B) with the crossfader in position A or B press
the desired effect button (41, 42 or 43) the effect will then be played in the time selected by the Beat Sync
Select buttons (40) once the effect is complete the output will automatically change to the opposite channel of
the crossfade without the crossfade physically being moved.
