IMPORTANT

Installer and Users please note:

These instructions should be read carefully and left with

the user of the product for future reference.

The S-Pedal is a Class-3 (safety extra low voltage) product, it
operates from a 12V supply provided by the Luminaire it is
controlling, or from an external 12V power supply (not supplied)

The S-Pedal is intended to operate the NJD Spectre and
Mirage. It will also operate NJD Datamoon, Chroma 50 and
Chroma HX, plus Raptor HX and Quasar HX with limited facilities.
Although the output is fully compliant with the DMX standard, it will
not operate any other lighting products.

The S-Pedal will control a maximum of 32 DMX luminaires:
several different types can be controlled from one S-Pedal.

Installation

1. If connecting to a Spectre, Datamoon, Mirage power

pack or other luminaire fitted with 5-pin XLR connectors

Connect the S-Pedal to the luminaire using a DMX lead (make
sure that it is a 5-pin XLR to XLR lead with all pins wired). No
connection is required to the DC input connector as power is
provided from the luminaire (on pin 5 of the XLR connector).

2. If connecting to a Mirage system fitted with terminal

blocks.

Connect the S-Pedal to the terminal block in the luminaire or
power pack. Connections are as follows:

Data+ = Pin 3

Data- = Pin 2

0V = Pin 1

+12V

SUPPLY

+12V = Pin 5

No connection is required to the DC input connector.

3. If connecting to a luminaire with ¼" jacks or 3-pin

XLRs for the DMX input.

Connect the S-Pedal to the luminaire using a 5-pin XLR to ¼"
jack lead, or 5-pin XLR to 3-pin XLR lead wired as follows:

5-pin XLR 3-pin XLR Jack

Pin 3 = Pin 2 = Tip

Pin 2 = Pin 3 = Ring

Pin 1 = Pin 1 = Sleeve

Pins 4,5 not connected

Connect a +12V supply to the 2.5mm power input socket
labelled "12V DC 50mA". Use a 12V regulated or unregulated
supply capable of at least 50mA. Some unregulated 9V supplies
will also work, but not a PP3 battery. Make sure that the centre
pin is positive.

Sound input

The S-pedal has an internal microphone, so no connection to
the audio source is required. However, when mounted on the floor
it is likely to pick up sounds from the stage or the sound of the
push-buttons being used. For this reason, it is possible to disable
the internal microphone and connect an external sound signal.
The "MIC" push-button switch turns off the
internal microphone.

To use an external sound signal, connect
an audio signal from the speaker output of a
power amplifier to the ¼” jack on the right
hand end panel labelled ‘sound’. The sound
input has an impedance of 33kW so that it
does not affect the loudspeaker/amplifier
loading. Voltages greater than 50V rms may NOT be
connected to a jack plug, so the largest amplifier that may be
connected would be a stereo amplifier that gives 1000W into 4W
(500W per channel), or 600W into 8W (300W per channel).

The sound input requires a signal of at least 1.5V rms before
it will start to operate (about ½W into 4W). This means that the
sound-chase may not operate at low levels. (½W is about
96dB(A) on an average pair of PA speakers).

Midi Input

The S-Pedal has a MIDI input, which can be used to trigger
the chaser instead of a sound input. The chaser will change on
each drum beat by detecting the "Note On" messages on Midi
Channel 10.

Setting the DIL switches.

1. Spectre: Set the Mode switches to DMX mode (OFF-ON)

Set the DMX address to 1 (all switches OFF),

2. Mirage (with DIL switches): Set the Mode switch ON.

Set the DMX address to 1 (all switches OFF),

3. Mirage (with 7-segment displays)

Set the function to F2.

Set the DMX address to 001

4. Chroma 50, Chroma HX

Set the DMX address to 17 (DIL switch "16" ON)

5. Datamoon

Set the DMX address to 33 (DIL switch "32" ON)

6. Raptor HX/Quasar HX

Set the function to F2 and the DMX address to 49.

OPERATION

FLOOD.

There are two Flood switches, which work identically, called
FLOOD-1 and FLOOD-2. The slider and the two rotary controls
above the switch can be used to set the brightness (power),
colour and shade of the colour (saturation) for each of the two
FLOOD settings. The top (multicoloured) LED shows the colour and
brightness selected on each flood switch. Pressing either of the
flood switches will produce the selected colour on the luminaires.
The yellow LEDs above the switches show which flood switch has
been selected.

BLACKOUT.

Either of the flood switches can be used as a blackout, by
setting the POWER slider to zero.

User Guide S-PEDAL

CHASE.

Press the chase button twice to select a chase, which is a
random colour changing effect at full brightness. The chase speed
will be determined by the time between the two switch presses.
(Press twice in quick succession for a fast chase). The CHASE
LED illuminates green whilst it is waiting for the second switch
press, then red when in chase mode. The slowest chase speed is

2.5 seconds between changes.

SOUND.

The SOUND switch selects sound chase. The chaser will
change colour on each beat of the music, using either the inbuilt
microphone, the external sound input or the Midi drum channel
(Channel 10)

FADE.

The fade effect can be switched on or off by pressing the
FADE switch. The green LED indicates when Fade is selected.

The fade effect operates as follows:

with flood: When changing between the two flood settings,
the colour and the brightness will change gradually between the
old and new settings taking approximately 10 seconds.

with chase: The chaser will change gradually between random
colours, spending half the time on the colour, and half the time
fading to the next colour.

with sound: The chaser will change colour on the beat of the
music, taking about a second to fade between the two colours.

Mimic

The output mimic LED allows the user an instant visual
indication of the unit’s performing mode. Please note that LED
colours are not an exact match for the colours of a filament lamp,
especially at low brightness levels.

Multichannel chase.

If using with multiple Spectres/Mirages, then in Chase mode
the S-Pedal can produce a different random colour on each
luminaire. To achieve this, set the DMX addresses to 1, 5, 9 and
13 on up to four Spectres. In FLOOD modes, all the luminaires will
produce the same colour. In CHASE mode the Mimic LED will
show the colour of the luminaire on DMX address 1. Refer to the

© NJD Electronics 2003 -Page 5-

User Guide S-PEDAL

instructions supplied with the luminaire as to how to set the DMX
address switches.

Use with other luminaires.

1. Chroma HX / Chroma 50.

Set the DMX address of the Chroma to 17.

All functions of the S-Pedal are available except the "shade"
control which has no effect. The Chroma has 8 fixed colours and
will choose the nearest colour filter to the colour selected on the
S-Pedal.

In chase mode, a different random colour can be produced on
each luminaire by setting the DMX address to 17, 21, 25 and 29
on up to four Chromas

2. Datamoon.

Set the DMX address of the Datamoon to 33.

The POWER control has no effect (the Datamoon has no
dimmer), and the SHADE control can be used to select the speed
of rotation of the pattern, from full speed anticlockwise to full
speed clockwise. The Datamoon has 8 fixed colours and will
choose the nearest colour filter to the colour selected on the S­Pedal. In SOUND mode, the Datamoon will perform "twist to
sound" if the SHADE control is set either fully anticlockwise, or
fully clockwise.

In chase mode, a different random colour can be produced on
each luminaire by setting the DMX address to 33, 37, 41 and 45
on up to four Datamoons.

3. Raptor HX and Quasar HX

The POWER control operates the dimmer, and the SHADE
control selects the speed of rotation of the barrel/dish. The
Raptor and Quasar have 8 fixed colours and will choose the
nearest colour filter to the colour selected on the S-Pedal.

In chase mode, a different random colour can be produced on
each luminaire by setting the DMX address to 49, 57, 65 and 73
on up to four Raptors/Quasars.

No control over beam scanning is available, the scanning
motor remains static at its centre position.

FAULT FINDING.

No LEDs lit

• No supply

If using a DC power supply, check that the output voltage and
polarity is correct.

If powering the S-Pedal from a luminaire, check that it
provides a +12V output on pin 5 of the XLR (Spectre, Datamoon,
Raptor and Quasar all do), and check that pin 5 is connected in
the DMX lead.

Luminaires do not operate correctly.

Check that the DMX address and Mode switches are set
correctly.

(If a Spectre is strobing, then the MODE switches are set
wrongly)

No response to sound

• Microphone switched off.

• External sound input signal too small.

No response to Midi

• No drum track on Midi Channel 10
