GLP® impression S350 User Manual 9

2. Avoiding damage

Do not point the front of the fixture towards the sun or other strong light sources. The
front lens focuses and concentrates light just like a magnifying glass. Strong light can
cause internal damage to the fixture, melting components or starting an internal fire
within seconds.

Figure 1. Avoiding damage from light sources

Damage can occur whether the fixture is powered on or off. See Figure 1. Damage
can also occur if the light hits the front of the fixture at an angle: the fixture does not
need to be pointing directly at the sun or other light source.

To avoid problems from strong light sources:

• Do not expose the front of a fixture to sunlight or any other strong light source.

• For outdoor applications during daylight, make sure that the front face of any fixture is

shielded or points away from the sun, even when not in use.

• Avoid pointing other high-powered beam lights directly at the fixture.

Do not pick up or carry the fixture by the front lens bezel, as it is not designed to
support the weight of the fixture. The LCD display is also fragile. Picking up or
supporting the fixture in these places could result in damage that is not covered by the
warranty.

Use only original spare parts. Any structural modification of the system will void the
product warranty.

Protect the front lens from dirt, dust and other contaminants. Do not touch the front
lens. Airborne particles and grease from your fingers can become baked onto the lens
and difficult to remove.

Clean optical components only as directed in this manual (see ‘Caring for your
product’ on page 36). Oils, solvents, and other chemicals commonly used for cleaning
can damage the lens coatings and surfaces.

Do not drop the product or expose it to mechanical stress.

Do not expose the product to heat (from other lighting fixtures for example).

4. Product features

The impression S350 from GLP is a high-quality moving head lighting fixture with a 350W
white light LED engine that provides outstanding color rendering and rich, natural
colors. Advanced German design allows exceptional performance and a versatile
feature set to be packed into one of the most compact moving head lighting fixtures
currently available, using GLP’s familiar ‘baseless’ format.

Rotating gobos, fixed gobos and a gobo animation wheel give impressive projections
and beam effects. A rotating 8-facet prism and a flexible four-blade rotating framing
module add to the impression 350’s packed feature set. Precisely engineered optics
give a powerful, homogenous and sharply defined beam throughout the fixture’s
zoom range. Power input via a Neutrik powerCON TRUE1 connector allows hot
plugging.

The impression S350 is designed for permanent or temporary indoor use. It can be used
outdoors if it is protected from moisture and precautions are taken to prevent damage
from direct sunlight. It may be placed upright on a level surface or suspended from a
suitable structure as described this manual.

The impression S350 is not suitable for household use, for use in any location where
unattended children have access to it, or for use in permanent outdoor installations.

Light source

The impression S350 is equipped with a 350 W white light LED engine with a rated
lifetime of 20 000 hours to >70% LED output.

Control panel

The control panel on the side of the yoke has a backlit graphic LCD display for setting
up the fixture and changing fixture settings. See ‘Control menu layout’ on page 25 for
a table showing the control menu structure and options available.

Pan and tilt

The impression S350 pans through 640° and tilts through 262°, with coarse and fine
control channels and self-correcting position feedback available.

Pan and tilt position feedback can be disabled/enabled using the control panel or the
Special / Control DMX channel.

The direction of pan and/or tilt movement can be reversed by selecting an Invert
command using the fixture’s control panel or the Special / Control DMX channel.
Inverting movement is a fast way of obtaining symmetrical effects without
reprogramming at the console.

GLP® impression S350 User Manual 13

Color

The impression S350 provides 0-100% continuous CMY color mixing and a 10-slot color
wheel with ten dichroic color filters including CTC (see Figure 3).

A good method of controlling color is to set CMY levels to 0% when you begin to use
the color wheel. Then, after you have selected a color on the color wheel, you can
fine tune it using the CMY channels.

CTC

The CTC DMX channel lets you adjust color temperature from 8 000 K to 2500 K by
deploying the CMY flags. The channel sets the flags into the perfect positions for
matching color temperatures on the black body line.

A recommended approach is to set CMY levels to 0% when you begin to use the CTC
channel. After you have selected a color temperature on the CTC channel you can
fine tune it using the CMY channel.

You can deploy the animation wheel with
the animation profile at continuously
variable angles from 0° to 90° to give
horizontal, diagonal or vertical animation
effects. You can also vary the speed and
direction of the animation wheel rotation.
When used in combination with static or
varying colors, rotating or fixed gobos,
framing and frost or focus, the animation
wheel makes a huge range of effects
possible, from abstract moving patterns to
simulated flames, branches in the wind,
ripples on water, etc.

German Light Products®

GLP® impression S350 User Manual 15

Framing

The four-blade framing module offers individual control of each blade, and the entire
module can be indexed continuously from -45° to +45°. Blades can be continuously
angled by +/- 30° and inserted by up to 100%, giving flexibility in choice of frame shape
and size right down to dead blackout.

Two framing control modes are available:

• PI (Position/Indexing) mode lets you insert each blade into the beam from 0% to 100%
on one channel and tilt each blade from -30° to + 30° on the next channel. Inserting
all four blades 100% into the beam will result in dead blackout. The fixture is set to PI
mode by default.

• LR (Left/Right) mode gives you individual control of the left-hand and the right-hand
sides of each of the four blades. In this mode, for example, DMX channel 25 gives
control of the left-hand side of blade 1 and channel 26 gives control of the right-hand
side of blade 1.

To use framing, select either PI mode (this mode is selected by default) or LR mode
using either the fixture’s control panel or the Special / Control DMX channel. Then use
DMX channels 25 – 32 to control the four framing blades and use DMX channel 24 to
set the indexed angle of the entire framing module.

Frost

The frost system offers two levels of frost effect that can give softer, more diffuse
projections: a continuously variable light frost and a continuously variable medium
frost.

Shutter effects

The impression S350 features an electronic dimmer / shutter system that provides pulse
and strobe effects as well as instant open and blackout.

Dimming

0 – 100% continuous dimming is available.
See Figure 7. You can select from two dimming curves using the control panel or the

Special / Control DMX channel: Linear and Extra soft:

• Light output using the Linear curve will appear to increase and decrease evenly
throughout the dimming range.

• The Extra soft curve gives finer control at low light levels (where the eye is more
sensitive to changes in light level) and coarser control at high levels.

The default setting is Extra soft.

Zoom

The impression S350 has a 1:5 zoom range. You can narrow the beam angle from 42°
to 8°.

Control on the Zoom DMX channel can be inverted. Normal control as the DMX value
increases is flood



spot. You can invert this using the control panel and the Special /

Control DMX channel so that control becomes spot



flood.

Focus and focus tracking

You can carry out 8-bit focus adjustment on DMX channel 17 and fine 16-bit
adjustment on DMX channel 18.

You can also set focus to automatically adjust to match different zoom angles if you
enable focus tracking in the fixture’s control panel or on the Special / Control DMX
channel. This feature is useful when zooming in mid-air effects.

Focus tracking can be optimized for three different projection distance ranges. Four
focus tracking settings are available:

• Focus tracking OFF sets the zoom and focus DMX channels to control zoom and focus
completely independently of each other.

• Focus tracking NEAR sets focus to automatically adjust for optimum sharpness at
projection distances of around 10 meters or less when the zoom angle is changed.

• Focus tracking MEDIUM sets focus to automatically adjust for optimum sharpness at
projection distances of around 11 - 20 meters when the zoom angle is changed.

• Focus tracking FAR sets focus to automatically adjust for optimum sharpness at
projection distances of over 20 meters when the zoom angle is changed.

If you have enabled Focus tracking NEAR, MEDIUM or FAR you can still override the
automatic focus setting: any manual adjustment that you make on the Focus DMX
channel will take priority over the automatic setting. However, if you change the zoom
angle again, the fixture will forget any manual focus setting and return to
automatically adjusting focus to match the fixture’s zoom angle.

German Light Products®

GLP® impression S350 User Manual 17

Fan modes

The four different cooling fan modes give you a range of options to choose from
depending on how you want to allocate priority between high-intensity light output or
low fan noise:

• Fan regulated gives priority to light output and only operates fans as necessary. If the
fixture is blacked out, fans run at minimum speed. When light output intensity is
increased, temperature regulation increases fan speed to the level necessary to keep
the fixture at optimum temperature.

If light output is set to maximum intensity but the fans can keep the fixture at optimum
temperature, there will be no regulation of light intensity. If the fixture begins to
exceed optimum temperature, light intensity will be limited until optimum
temperature can be maintained.

• Fan constant high mode is optimized for maximum light output and suits operation in
high ambient temperatures. Fans are set to constant operation at high speed. Light
output intensity is limited smoothly if it becomes necessary in order to keep fixture
temperature at optimum level.

Besides maximizing light output in high ambient temperatures, you can use this mode
to cool down a fixture quickly or to remove dust from cooling fans.

• Fan constant medium sets fans to constant operation at medium speed. Light output
intensity is reduced to a level where it will normally remain constant at ambient
temperatures of up to 45° C (113° F). Intensity is smoothly limited further if it becomes
necessary in order to keep fixture temperature at optimum level.

• Fan constant low mode sets fans to constant operation at low speed and is optimized
for minimum noise. Light output intensity is reduced to a level where it will normally
remain constant at ambient temperatures of up to 30° C (86° F). Intensity is smoothly
limited further if it becomes necessary in order to keep fixture temperature at
optimum level.

In all fan modes, if fixture temperature reaches a dangerous level, LEDs will be shut
down for a period until the fans have brought the temperature down to a safe level.

You can set the cooling fan mode using the control panel or the Special / Control DMX
channel.

Effect wheel shortcuts

By default, the color wheel and gobo wheels take the shortest, fastest route from one
slot to the next, even if this means that they may pass through the open position. To
avoid the wheels passing through the open position when they change from one slot
to the next you can set Effect shortcuts on the Special / Control DMX channel to OFF.

Behavior when the fixture is not receiving a DMX signal

You can set the fixture to react in four different ways if no DMX signal is present (if the
fixture is being controlled by DMX but the DMX signal stops, or if you apply power to
the fixture when no DMX signal is present):

• Hold sets the fixture to continue obeying the last DMX values it received. This is the
default setting.

• Blackout sets the fixture to black out whenever it is not receiving a DMX signal.

www.glp.de

18 GLP® impression S350

User Manual Rev. A

• Stand-Alone sets the fixture to play its stored stand-alone scene (see DMX Shot below)
when the fixture is not receiving a DMX signal. If no stand-alone scene is stored in
memory, the fixture will black out.

• DMX Shot takes a snapshot of the DMX values that are currently being received and
stores them in the fixture’s memory as its stand-alone scene. The fixture will display this
stand-alone scene if it is set to Stand-Alone (see above) and is not receiving a DMX
signal.

You can select one of the four settings above using either the control panel or the
Special / Control DMX channel.

Stand-Alone operation

If the fixture is set to Stand-Alone and if a stand-alone scene has been stored in its
memory using the DMX Shot command, it will display its stand-alone scene at all times
when it is powered on but not receiving a DMX signal. You can therefore use this
setting if you want fixtures to automatically start stand-alone operation when you
apply power to them.

PWM frequency

You can change the LED dimming PWM frequency in order to avoid flicker and beat
frequencies in video images. To do this, select a new PWM frequency using either the
Settings DMX channel or the fixture’s control panel.

The default PWM setting is 3000 Hz. You can set the PWM frequency to 2200 Hz,
3000 Hz, 4800 Hz, 9600 Hz or 25 kHz. Note that a higher PWM frequency may affect
dimming performance.

The PWM frequency setting is stored in the fixture and is not affected by cycling power
off and on. However, it will be affected if you use the Factory default command in the
control menus.

As a rule, you should set all the fixtures in an installation to the same PWM frequency in
order to ensure the same performance.

Installation options

The base has four Camlock fastener points and two M10 threaded holes for a
removable tripod (supplied), omega brackets or direct mounting of half-coupler
clamps, allowing various rigging options.

Two eyelets are provided for safety cable attachment.

secure.

See Figure 10. Fasten the

safety cable to one of the
safety cable attachment
points in the base of the
fixture and loop it around a
secure anchoring point such
as a truss chord. Remove as
much slack as possible in the safety cable (by looping it more than once around
the truss chord, for example).

Secure the safety cable and check that it will hold the fixture if a primary

attachment fails.

Placing on a surface

If you install the supplied tripod on the base of the fixture, you can stand the impression
S350 upright on a flat, stable, horizontal surface in any location where the fixture is not
accessible to the public and will not present any safety risks.

If necessary to prevent the fixture from moving or
falling, pass a ratchet strap, webbing or other suitable
bracing strap through the safety cable attachment
points in the base (see Figure 10) or the strap
attachment points in the tripod stand (see Figure 11)
and fasten it to secure anchoring points. Make sure
that the strap is tight enough to hold the fixture, but do
not distort attachment points by overtightening the
strap.

If the fixture may cause injury or damage if it falls,
secure it with a safety cable as described in ‘Safety
attachment’ on page 20.

Make sure that the head will not collide with anything
when it tilts and rotates.

Connecting to power

The AC mains power supply must include a connection to ground / protective earth. It
must be protected against ground / earth leakage and overload. The auto-sensing
power supply accepts AC power at 100-240 V, 50/60 Hz. Do not connect the fixture to
power at any other voltage or to an external dimmer.

The impression S350 has a 3-conductor Neutrik powerCON TRUE1 socket that accepts
AC power from a Neutrik powerCON TRUE1 female cable connector.

Although powerCON TRUE1 connectors support hot-plugging, it is still good practice to
shut down power to power cables or move Power ON/OFF switches to OFF before
connecting power cables to fixtures.

To connect the fixture to power:

Check that power to the power input cable is shut down or that the fixture’s power

switch is set to OFF.

See Q in Figure 2 on page 11. Note the position of the keys and keyways on the

power cable connector and Mains In socket and align them with each other. Insert
the cable connector into the socket and twist clockwise to lock.

Before applying power by energizing the power cable and/or switching on the

power switch, check that the head is unlocked and can move freely and check
that nobody is looking directly into the front of the fixture.

Installing power connectors

It is possible to install a cord cap / mains power plug that is suitable for your local
convenience receptacles / power sockets on the supplied power input cable. If you
do this, check that the cord cap / plug is rated minimum 250 V, 16 A, that it has a
connection to ground / earth and that it has an integral cable grip. Follow the cord
cap / plug manufacturer’s assembly instructions.

User Manual Rev. A

If you need to install a Neutrik powerCON TRUE1 connector on a power cable, follow
the instructions given in the Support area of the Neutrik website at www.neutrik.com.

Respect the color coding used in the supplied power cable and in your local mains
power wiring system. US and EU systems use the color coding shown below:

Live or L Neutral or N

Ground / Earth or

US system Black White Green

EU system Brown Blue Yellow/green

Main fuse

See Figure 12. The main fuse sits in a holder in the
base.

If the fixture appears to be completely shut down
even though power is applied, the main fuse may
have blown. Disconnect the fixture from power
before replacing the fuse. You can open the
fuseholder with a flat-headed screwdriver. Replace
only with a fuse of the same type and rating.

If the fuse blows repeatedly, disconnect the fixture
from power and contact GLP for service and
repair.

Connecting to a DMX control data link

The impression S350 provides 5-pin and 3-pin XLR IN and THRU sockets for connection to
a USITT DMX512 data link.

Connectors use standard DMX pinout:

• Pin 1 = Ground

• Pin 2 = Negative / data cold

• Pin 3 = Positive / data hot.

• Pins 4 and 5 are not used.

If you would like any advice with planning and installing a DMX link, your GLP supplier
will be happy to provide assistance.

* Move from zero and hold value for 3 seconds to apply

** Move from zero and hold value for 5 seconds to apply

Notes:

Percentage values are calculated by dividing DMX values by 2.56 and rounding to the
nearest 0.1%.

To apply a command on Channel 33 (Special / Control), start at a value of zero, then
move to the required value and hold it for the required time (e.g. 3 seconds). If you
move to the required value from any other value than zero, the command will not be
applied.

To adjust the PWM frequency using the Special / Control channel, start at a value of
zero, move to the required value and hold it for at least 5 seconds.

Default settings are written in bold type.

9. Caring for your product

Cleaning

The buildup of dust, dirt and other airborne particles will reduce the fixture’s light
output. It will also prevent the fixture from cooling correctly, and this will reduce the
fixture’s lifetime. The rate of dirt buildup will vary depending on environmental factors
such as airborne dust, use of smoke machines, airflow from ventilation systems, etc. The
fixture’s cooling fans will accelerate buildup, and any smoke particles that are present
in the atmosphere will increase the tendency for dirt to clog.

To get the best performance and lifetime from the fixture, inspect it regularly and clean
it as soon as you see signs of dirt buildup. Assess the operating environment each time
you begin to use the fixture. In dusty or smoky conditions, inspect the fixture after a few
hours and check it frequently – the fixture may attract dirt faster than you expect.
Draw up a cleaning schedule that will make sure that dirt is removed before it can
build up.

Use the following guidelines:

• Disconnect the fixture from power and allow it to cool completely before cleaning.

• Do not use solvents, abrasives or any other aggressive product to clean the fixture.

• Vacuum or use low-pressure compressed air to remove dust and loose particles from

surfaces and air vents. Prevent the blades of cooling fans from turning before you aim
a vacuum or air jet at the fan, or you may spin the fan too fast and damage it.

• Clean glass components by wiping gently with a soft, clean, lint-free cloth moistened
with a weak detergent solution. Put the solution on the cloth, not on the surface to be
cleaned. Avoid rubbing glass surfaces. If particles are stuck to the glass, try to lift them
off by dabbing them repeatedly with a cotton swab or moistened lint-free cloth.

• Dry the fixture with a soft, clean, lint-free cloth or low-pressure compressed air before
reapplying power.

Lubrication

The fixture does not normally need lubrication. If any moving parts show signs of rough
movement, consult a GLP service partner.
