Introduction
The v3001 is designed as an simple to install replacement for white light readers in 35mm
projectors, to allow playback of Cyan Dye soundtrack films. It can also be used to upgrade first
generation LED retrofit kits where greater reliability noise may be an issue. The unit performs well
with all types of tracks, be they traditional black, high magenta or cyan dye.
The unit consists of a high stability laser diode and internal optical components, housed in a
standard package. It is intended to replace the sound optics lens in an existing projector, and a
variety of adaptor sleeves are available to fit most machines. Alternatively, a bracket is available
to allow fitting to ANY projector where a standard cylindrical lens is not used (for exa mple Kalee,
Ernemann).
Because of the highly focused light emitted from the laser, the unit works with the existing mono or
stereo solar cell already fitted to the projector, removing the need for a pre amplifier and increasing
the gain of the system substantially.
Lasers can be powered from any 3.7VDC regulated source, including the cinema’s stereo
processor (via two small diodes to reduce 5V to 3.7V). The current drawn by the v3001 is small
indeed, at around 35mA DC. No special power supply is nee ded, and in an emergency the unit
will work off three 1.5V batteries or even a mobile phone charger.

1.03 Warranty
The V3001 is warranted to be free from defects in manufacture for one year from the date of
shipping. If a failure is suspected, please co ntact us and get a returns authorization – note items
returned without this will be sent back. If a problem occurs during the warranty period, we will
repair or replace the unit (at our option) following return and evaluation in our office. This
warranty covers only equipment supplied and return of the unit via surface post. We make no
warranties beyond this and limit our liability to replacement or repair of the faulty unit. In the
unlikely event of a failure it is recommended that the existing white light be retained for emergency
installation.
Our warranty is based on the unit being installed by trained and competent persons using test gear
as listed. It specifically excludes damage resulting from misuse, poor installation or electrostatic
discharge, either cable or airborne (see notes on installation).
1.04 Electrical noise – READ THIS !
The laser diode within the V3001 is a CMOS devices and like any semiconductor device can be
damaged by “wired” or airborne electrical noise. Projection rooms are full of electrical noise,
coupling high current DC lines to the xenon lamp with an extremely high voltage AC emitt ed from
the lamphouse ignitor – if the strike of the xenon is audible through the theatre sound system then
this is one indication of certain noise.
The V3001 contains internal circuitry to help protect the unit against such noise, and by following
the listed advise the unit will be further isolated from the noise source.
- If installing a V2001, ensure that the laser body is electrically isol ated from the projector
chassis. Ensure that the plastic sleeve is in position and that the grub screw to secure the
laser has not penetrated this sleeve and made a connection. The V2001 body is connected
to the positive voltage rail and this can also ca use problems with older power supplies .
- If installing the V3001, we also recommend ensuring isolation from chassis also. Whilst the
projector and lamphouse in your theatre are no doubt earthed, the high frequency and
voltage of ignition and motor controll ers invariably generates noise and this is radiated
throughout the projectors steel chassis. (This can be demonstrated by attaching an
oscilloscope probe to the projector chassis and striking the xenon lamp).
- Keep the power cables to the laser as short as possible, and use foil screened cable. The
screen should be connected ONLY at the power supply end, and should be connected to a
clean earth (not the projector chassis)
- Do not connect either the +ve or –ve rail of the laser or power supply to earth
- Install the diodes (supplied) near to the laser – this adds a further level of isolation
- Observe the correct laser polarity and check the operating voltage with an accurate meter
- Do not try and use existing power supplies – the V3001 kit comes complete wit h a power
supply, use this. AC mains to this should be sourced from a clean supply and an earth with
a wired connection to an electrical intake.
- A v2001 has a red label, whereas a v3001 has a blue label and a shorter DC cable.

Installation prerequisites
Installation should be undertaken by an engineer familiar with cinema processors and A chain
procedures, using the following equipment;
- Real time audio spect rum analyzer and leads to couple with the apt cinema processor
- Dual trace oscilloscope and connecting leads
- Test films – reference tone, pink noise, Left / Right crosstalk film, illumination test film,
SMPTE buzz track
- Crimp tool and general hand tools
We estimate installation to take around two hours, including alignment.

Before installation commences, run a known good film in the theatre and evaluate the existing
system.
2.3
Power supply and connection
This involves working with mains electricity and should be undertaken by trained personnel.
Isolate all power before starting.
There are two options for supplying the laser;
1. Utilize the power pack supplied with the kit. This is recommended
2. Source the supply from the 5VDC rail of the cinema proces sor. This is a perfectly good
power supply however using this can cause some confusion when fault finding.
In either case, the DC connections are the same.
If you are using the power pack, first wire up the 13A socket for the power supply. Connect this to
a 220 – 240VAC clean supply – the connections in the socket are clearly marked. Use the mains
cable supplied – don’t confuse this with the audio cable also supplied (the mains cable is
three core 0.5mm flex, with Brown, Blue and Green conductor insulat ion). It is possible to switch
the AC supply of the laser on and off with the projector motor – do this via a spare contact on the
motor switch or a set of relay contacts slaved off the projector motor.
Set the power pack to 4.5VDC.
Now connect the DC cabling to the laser. It is important to protect the DC cable from electrical
noise. If the laser is to be located within a meter or so of the laser, you can connect the power
supply directly to the diodes that feed the laser. Otherwise use the screene d cable supplied and
connect as follows.
The diodes offer the required voltage drop to operate the laser at 3.7V as well as tendering some
isolation – depending on mains voltage you may require only one installed. Check the voltage on
the laser – this should be as near as possible to 3.7V and never over 4V.

The laser replaces the existing sound optics lens.
First, Isolate all power and remove the projector’s exciter lamp and sound optic lens – note that in
some cases it is necessary to remove the sound drum to access this. Once removed, thoroughly
clean the inner surface of the receptacle for the sound optic lens – the laser is a tight fit and this
will make alignment easier.
Fit the adaptor sleeve over the laser body, locating it close to the where the laser is secured in the
projector. Now install the laser and sleeve, with the arrow and slit width screw on the laser
towards you (i.e. away from the projector chassis).
Locate the laser approximately 5mm from the film plane, and ensure that the existing solar cell is
approximately 2mm behind the film plane. Check that the laser beam is hitting the cell.

Alignment
Connect the RTA and oscilloscope to the cinema processor. Set the processor slit loss
adjustments (HF gain) to minimum and the optical gain controls to around 20%. Clean the solar
cell with a cotton bud and suitable cleaning fluid.
Coarse focus adjustment - Lace up and run PINK NOISE (Dolby Cat 69P or similar). Observe
the RTA display – move the laser body in and out (towards and away from the screen) to achieve
maximum high frequency gain. Rotate the laser a little to further achieve this.

Coarse level adjustment - Lace up and run REFERENCE TONE (Dolby Cat 69T or similar).
Adjust the cinema processor’s optical gain controls in the usual manner.
Poor focus and azimuth
Good focus and azimuth
Slit width adjustment – Lace up and run BUZZ TRACK (SMPTE or similar). Listen for the low
frequency tone - observe this on the oscilloscope or RTA. Adjust the film’s scanning position in
and out to the point where this low level tone disappears. Note that on some projectors the exciter
lamp housing is moved and the film remains static. Now loosen the slit width locknut on the laser
and gently adjust the slit width grub screw to the point where the high frequency tone of the Buzz
Track disappears. Lock this adjustment.
Left / right adjustment – Lace up and
run LEFT / RIGHT test film. Adjust the
horizontal position of the cell to achieve
equal and minimum crosstalk. If
excessive crosstalk is apparent on both
channels check the cell position relative to
the film – it may need to be moved closer
or further away from the film. At this
Cell adjustment OK
Cell out of adjustment
stage we recommend that the connection
of the cell be checked. With the loop running, slowly insert a card of some sort between the cell
and the light source from the operating side of the projector – the right hand channel should fade
out first, followed by the left.
Azimuth adjustment - Lace up and run PINK NOISE (Dolby Cat 69P or similar). Set the
oscilloscope to plot X vs Y. Gently rotate the laser body to achieve a straight diagonal line. We
recommend using a adjustable spanner on the laser to increase accuracy of this adjustment.
Final focus adjustment – Still running PINK NOISE, observe the RTA display – again move the
laser body in and out (towards and away from the screen) to achieve maximum high frequency
gain. Try not to rotate the laser whilst doing this. Repeat this and the azimuth adjustment to
achieve the best overall response.

Illumination check – Lace up and run Dolby
Cat 556 illumination test film. Observe the
RTA for the six separate frequency bands –
any drop off on the outer bands indicates
poor illumination. If drop-off is visible at the
lower end of the spectrum, move the film
position (as you did running Buzz track).
Poor illumination
Good illumination
If the drop-off is at the high end of the spectrum, adjust the slit width grub screw. Following this
you will need to repeat the cell adjustment with Left / Right test loops.
Processor adjustment - Lace up and run PINK NOISE (Dolby Cat 69P or similar). Observe the
RTA display – adjust the processor’s HF gain / slit loss adjustment controls to achieve a flat
response. Lace up and run REFERENCE TONE (Dolby Cat 69T or similar). Adjust the cinema
processor’s optical gain controls in the usual manner.
NOTE – all adjustments interact with each other – to get best results we recommend
repeating this procedure from “slit width adjustment” after changes are made.

Installation on a different projector
Some projectors do not use standard cylindrical sound optic lenses, and require additional
measures to install a v3001 laser. In some cases it is simply a matter of choosing an adaptor to
best fit the projector’s lens tube and adjusting as normal, however in other cases the exciter lamp
and lens housing are not suitable. A bracket is available to install the v3001 directly onto the
projector chassis – we have used these with success on Ernemann and Kalee projectors.
Installation of this requires the removal of the old exciter lamp housing, drilling and tapping threads
in the projector chassis and bolting the bracket on via long bolts or studded rod. Please contact us
for advise on this – the job takes a few hours but can produce great results.
Some Kalee sound heads use a variety of condenser lenses in the optical A chain and can deliver
variable results when upgraded. We recommend replacing the Kalee cell and opt ical arrangement
with a standard stereo pick up designed for a Century machine or similar. Upgrading is a half
day's work and involves drilling and tapping new mounting holes however final results can be
fantastic. Please talk to us if you have a Kalee - installing the laser on top of the existing sound
optics will certainly result in an improvement in sound and full cyan compatibility however to realize
the potential of the laser you may need to upgrade some items.
Physical installation
The v3001SPECIAL1 kit is supplied with a bracket for mounting on the chassis of a projector
where the existing sound lens is not a standard cylindrical unit, for example the Kalee or
Ernemann soundhead. In these cases it is possible to remove the existing exciter lamp ho using
and fit the bracket directly to the projector or soundhead chassis. We recommend the following
procedure;
_____________________________________________________________________________________________________________________
V3001 INSTALLATION AND ALIGNMENT MANUAL – REV 0505_1
PAGE 9 OF 12
1. Remove the existing exciter lamp housing and isolate it’s electrical connections
2. Install the bracket mounting base so that the laser is at right angles to the film. The bracket can
“clasp” the laser on either the rear, 16mm diameter section (use a sleeve supplied with the
bracket) or via an 18mm laser sleeve at the front of the laser. We recommend that the later
method is used as it is advantageous to clamp the laser as close to the film plane as possible.
Ernemann 7, 8, 9, 10, 12 – the existing M6 tapped hole in the projector chassis (formerly used to
hold the exciter lamp housing in place) is ideally placed to take the upper hole of the new mounting
bracket – tap a thread and fit a M4 or M5 bolt to the lower hole . The upper hole will require a
longer M6 bolt (20mm). The hole in the bracket also needs enlarging. Contact us for help.
Alignment of the SPECIAL1 kit
As well as the usual adjustments, the flexible nature of the SPECIAL1 bracket allows further
adjustment. We recommend the following method;
1. Lace up and run Cat69T reference tone and rotate the laser vertically to achieve maximum
level.
2. Perform coarse focus and azimuth as normal
3. Run BUZZ TRACK and adjust the laser towards and away from the projector chassis to
eliminate the low level tone. Now adjust the slit width screw to eliminate the high frequency
tone.
4. Continue with all other adjustments as described in the “alignment” se ction of this manual

Troubleshooting
The v3001 is a sealed unit and should give years of good service.
Can’t achieve good results when running Cat556 – if good illumination across the film plane is
not possible, it could be that the cell is too close to the film. Laser light behaves differently to white
light and the focal plane is slightly different. Try moving the cell further away from the film.
Poor HF response – check that the laser’s internal alignment has not been disturbed. The red
arrow on the side of the laser should point directly at the small grubscrew on the front body. This
can be aligned by eye and then checked in a similar manner as setting the azimuth
Laser cuts off when projector / xenon etc are switched – this is a sure sign of electrical noise
reaching the laser. Review the power supply and connections
3.01 v3001 Maintenance
Cleaning – the lens of the laser and the stereo cell should be cleaned regularly with a cotton bud
moistened with a little alkali based cleaning solutio n (e.g. water based window cleaner).
Level adjustments - The v3001 is a sealed unit and following installation no adjustments are
required. The output of the laser degrades at a far slower rate that the output of a white light or
LED, so reference level adjustments (Dolby tone) should seldom be required. We recommend that
these levels are checked every three months or so. If more frequent adjustments are required
please contact us.
