IMPORTANT

Installer and Users please note:

These instructions should be read carefully and left with

the user of the product for future reference.

The Quartet 300 must be installed by a competent
electrician in accordance with the current IEE wiring
regulations.

Fix the Quartet with the hanging bracket provided. If the
Quartet is to be mounted with the bracket below the
product, then remove the handle, and re-assemble beneath
the product. The Quartet must be installed the correct way
up. Installing the Quartet upside down will seriously affect
lamp life.

To comply with Health and Safety legislation, a safety
chain must be employed. A loop is provided at the top of the
rear panel for fixing the safety chain.

0.8m

Ensure that there are no obstructions to the ventilation,
the air intakes are around the edges of the colour-filter
frame, and hot air is exhausted through the fan. Also ensure
that there are no readily flammable items in contact with the
case.

The Quartet is only intended for use indoors.

Connect the Quartet to the output of a four-channel
lighting controller, or a dimming or switching pack, using an
Electrovision Lightcon F321BE connector. Connections are
as shown opposite:

This symbol means that the Quartet should be
mounted at least 0.8m from any object that it is
illuminating.

The Quartet 300 must be earthed

The diagram shows the internal view of the plug.
The minimum cable size is 0.75mm2 for the live and

earth connections, and 1.5mm2 for Neutral, although two

0.75mm2 cores may be connected in parallel.
Ensure that the lighting controller has adequate

switching capacity for the Quartet.

• A minimum is 300W per channel for one Quartet,

• 600W per channel for two and

• 900W per channel for three. Please note that if all

four channels are switched on at the same time, on three
Quartets, the current drawn from the mains will be 15.5
Amps. This would blow the fuse in a 13A mains plug.

If you wish to use more than two Quartets, where

there is a possibility of all four channels being switched
on at the same time, then make sure that you have a
mains supply and connectors capable of handling this
amount of current.

If the Quartet is connected to an NJD four-channel

lighting controller with an Electovision Lightcon F321CAD
output connector, Red will be on channel 1, Yellow on
channel 2, Green on channel 3 and Blue on channel 4.

If the Quartet is to be operated from a dimmer, it is good

practice to keep the cable between the dimmer and the
Quartet as short as possible, and away from cables carrying
low-level signals, such as microphone cables, and from the
antennae of radio microphone receivers.

The Quartet needs no separate supply for the fan. The

fan will operate whenever any channel is at more than 25%
of full brightness.

Replacing the lamps

In order to replace a lamp, disconnect from the mains

supply or controller, and unscrew the two fixing knobs at
either side of the colour filter plate. Then remove the colour
filter plate and reflector assembly by pulling forwards (this
may be quite a tight fit). The lamps are now accessible, and
the faulty lamp may be replaced by a new lamp type CP97.
Do not touch the glass bulb. Hold the lamp with the paper
packet in which it is supplied. If the bulb is accidentally
touched, clean it before use with methylated spirit,
otherwise lamp life may be reduced or the lamp could
shatter due the deposits of grease from the skin reacting
with the quartz at high temperature.

Replace the colour filter and reflector assembly, making

sure that it goes back the same way round. (Red and blue
are at the top).

Cleaning

The Quartet should be cleaned periodically as dust will

tend to obstruct the fan, and impare the ventilation system.
Clean the dichroic filters with a soft lint-free cloth using
alcohol or hi-fi cleaning fluid

Operation

The Quartet is a floodlight, and does not produce a

focused beam of light. Aim the lantern in order to get the
best illumination. The barn doors may be used to control
light spill at the edges of the area to be illuminated, but
should be used with care, as multiple-coloured shadows will
result when more than one lamp is illuminated.

The Quartet must not be operated with the barn doors

completely closed, as this will result in an obstruction to the
ventilation system, and will overheat the barn doors.

Do not place coloured gels in front of the Quartet. The

dichroic filters must not be replaced by colour gels.

It is recommended that all four barn-doors are closed

when the product is to be transported, in order to protect
the dichroic filters, which are expensive to replace.

Lamp life

Lamp life can be extended by the following techniques:

1) Operate at less than full brightness. (lamp life is

doubled at 85% of full power)

2) If flashing or chasing the lamps, EITHER: use a soft-

fade type chase.

OR: leave the filament slightly illuminated so that it just

glows red-hot similar in appearance appearance to the
element of an electric fire when the Spectre is off. This can
be done by setting the preheat control in the dimming pack,
or by setting the slider to about 3% instead of completely
off.

3) Leave the Quartet to cool for about 5 minutes before

moving it. Filament lamps are most vulnerable to failure just
after switching off.

The expected lamp life at various settings of the dimmer

are shown below. The supply voltage is assumed to be 240V,
longer lamp life will be obtained if the supply voltage is lower.

Setting Power Brightness Lamp Life(hours)

0% 0W 0% *
25% 37.5W 1.5% *
50% 90W 12.5% 300,000*
75% 190W 42% 2250
100% 300W 100% 75
*At power settings this low, the lamp life will be

determined by other factors than the power consumed by
the lamp, such as switching on and off repeatedly, or
mechanical damage.

Colour Mixing

An infinite variety of colours can be obtained by mixing

the four colours together.

Some examples are as follows:
Magenta: 100% red, 100% blue
Cyan: 100% green, 55% blue
Lime Green: 100% green, 30% yellow
Orange: 100% red, 40% yellow
Purple: 100% blue, 45% red
Pink: 100% red, 50% green, 50% blue
White is obtained by illuminating all colours at the same

value. A "daylight" white can be obtained by including more
blue and green, and slightly less red and yellow.
