INTRODUCTION
Congratu lations
As a multi-image professional, you have chosen a system that, by any
criteria, is the most significant advance yet made in your field.
lndeed, the SHOW PRO V represents a totally new concept in multi-image
programming. one pioneered by AVL with the predecessor to this unit, the
SHOW PRO lll . . . all dissolves and program operations built into a single
computer-control led package.
with the sHow PRo v, you now have total control of up to 15 slide
proiectors at your f ingertips. The computer generates all cuts and dissolve
blends, and additionall keeps track of all aspects of the program,
including slide projector tray positions and lamp status. ln effect, the
computer does the "bookkeeping," allowing you to spend your time
perfecting the artistic and creative elements of a show.
Until recently. a completely computerized programmer/dissolve system
was merely an idea entertained by many professionals In the AV field. The
prospects for production of such a system remained dim, however, until
the introduction of high technology micro-processor integrated circuits.
With their advent, AVL took full advantage of the new technology. As
a result, multi-image programs can now be generated, reviewed and
edited more simply and far faster than ever before.
The SHOW PRO V is designed to control a number of slide show formats,
including five screens with three projectors focused on each, a standard
upon which the descriptions in this manual are based.
Our completely new system also has ten auxiliary channels for controlling
additional equipment such as supplementary slide projectors, a 16 mm
projector, or room lighting.
Each projector in the SHOW PRO V System may be controlled
independently, allowing sophisticated split-screen and overlapping
image effects. The result: Shows with motion and rich visual effects
that an audience may well assume are produced by film . . . produced
instead with the simplicity and economy of slides!
This manual will help familiarize you with the remarkable SHOW PRO V.
From that point on, your multi-image programs can soar as high as your
own imagination.

The keyboard controls of your SHOW PBO V are designed for simple
trouble-f ree editing and programming, with all phases of operation
apparent at a glance, all command functions at your f ingertips. Here
are the specific functions of each keyboard control:

Power
Activates the system in the "ON" position. This key switch can be
removed from the unit in the on position, a safety feature that prevents
accidental interruption of a program.
Memory
This is a three position switch:
(A) The far left position is "DISCONNECT".
(B) The center position is "NORMAL".
(C) The far right position is "TAPE BYPASS".
Normal Position
This position is for:
(A) Loading memory from keyboard during programming.
(B) Recording data to magnetic tape from memory after
programming.
(C) Reloading memory from magnetic tape.
Tape Bypass Position
While in this position the SHOW PBO V wilt execute all cues from
magnetic tape, but will not enter these cues into memory, nor change
the current cue counter position.
For Live portions of your show, cues can be accessed from memory
without changing the memory switch position.
The Tape Bypass mode allows the operator to easily transfer from
"Canned" show to "Live" show and back as many times as is necessary,
maintaining the use of reverse cue in all Live portions.
Disconnect Position
This position prevents keyboard commands and programmed data off
magnetic tape from entering memory.
Bemote Cue
Should be in NORMAL position during most operations, allowing cue
commands by remote control. The red light to the left of the switch
will come on whenever a remote hand control is activated, regardless of
whether the switch is in NORMAL or DISCONNECT. ln DISCONNECT,
a remote cue will not activate the programmer.
NOTE: The Remote Cue switch must be in the NORMAL position
when interconnecting SHOW PRO V's. Connect the program interconnect
plug to the Remote Cue receptacle of the second SHOW PRO V.
Simultaneous operation of both units can be achieved from one Remote
control. This Remote controller would be plugged into the Remote
control receptacle of the f irst SHOW PRO V.

This is a three-position switch. ln DISCONNECT (left position) tlre
switch disconnects all outputs to projectors and auxiliaries. A red light to
the left of the switch remains on as a reminder to the operator. Use
DISCONNECT with care. When rhe DISSOLVE switch is in this positlon.
program memory responds to commands as if it's advancing or reversing
trays. As a result, it will lose track of projector tray status. ln NOBI\4AL
(right position) all dissolves are connected and will respond to commands.
ln STANDBY (center position) all projector lamps are turned off but
dissolves are connected and will respond to commands.
Sequence
With this switch in the TWO position the programmer will sequence
between left and right projectors, although the center projector will be
activated if the CENTER Screen Control button is punched. With the
SEOUENCE switch in the THREE position the programmer will
sequence left-center-right.
Keyboard
This switch primarily governs the editing controls on the SHOW PRO V.
When the keyboard switch is in the NORMAL position allediting
buttons activate on a one step basis. The Keyboard switch should be in
the NORMAL position for all playback situations.
The "Fast Edit" position allows the operator to "Edit" any number of
cues in a Block, or "add" any given number of cues in a Block. This
position also changes the run control from a hold down position to a
Latching situation.
Keyboard "Fast Edit" changes the Reverse "O" function also, allowing
extremely rapid reversing through memory.
For more information on each Editing control, and the "Fast Edit"
position for each control, refer to "Editing Controls".
NOTE: When the Keyboard switch is in the "Fast Edit" position the
SHOW PRO V will alert the operator by blinking the Red Mag Tape
Status Led.
Mag Tape Switch
MAG TAPE VEBIFY is the far Left position, indicated by a Red Light.
ln this position a program that has been dumped to magtape may be
completely checked without disturbing the contenrs of the SHOW PBO
V memory.
To verify a program that has been dumped to magtape:
(1) Set Mag Tape switch to Tape Verif y position.
l2l Reset the SHOW PRO V memory and rewind magtape.
(3) After connecting an Audio cable from Line Out of the recorded
track to the Play jack on the back of your SHOW PRO V, start
Tape Deck.
Each time a cue is Read back into the SHOW PRO V. it is checked and
verified against memory. lf the data is correct the cue counter will
advance one step. lf any cue is incorrect the cue counter will indicate
BAD 4.
lf all cuesare good, the cue counter will indicate the number of good
cues. lf this count is the same amount as in memory, the dump is
assured to be accurate and of high quality.
PROGRAM position is for programming your show and transferring all
programmed data to magnetic tape.
PLAY position is for presenting shows from mag tape or memory,
Program Timing
This switch will undoubtedly be used more than any other during
programming. ln the STEP position it allows step-by-step programming.
ln the PLAY position it allows playback of single cues as welI as pre-
programmed high speed sequences.

Cut
Commands an instantaneous switch f rom one projector to another. Any
projector going off will automatically advance.
(For further details see High Speed Programming)
2 Second (2 SEC)
4 Second (4 SEC)
8 Second (8 SEC)
These buttons are used to select the timing for blends from one projector
to another. Any projector going off will automatically advance.
The combination of buttons 2 SEC and 4 SEC produce a 3 SECOND
Dissolve Speed.
The combination of 4 SEC and 8 SEC produces a 6 SECOND Dissolve
Speed.
Alternate (ALTI
ALT used in conjunction with a screen number switches lamps between
projectors similar to a cut without a Tray advance.
The Alternate button may be combined with any Dissolve speed to
perform a dissolve alternate (no tray advance) including the 3 and 6 SEC
combination.
Shift Command Feature
Using some control buttons on the SHOW PRO V combined with "SH lFT"
adds a host of performance features:
(A) SH IFT combined with the Dissolve Speed Controls for additional
speeds.
(B) SHIFT combined with ALT for high performance screen effects.
(C) SHIFT combined with screen numbers for DISSOLVE FREEZE.
(D) SHIFT combined with forward for high speed actlon at 20 CPS
(Cues Per Second).
(E) SHIFT combined with Beverse for shifting back to normal
speed 1 0 CPS.
lf a SHIFT can be combined with a control button this will be pointed
out, and the procedure and result explained as we define each control
button.
Dissolve Speeds Combined With Shift Button
SHIFT + CUT = HARDCUT. The down going projector begins advancing
before the Lamp Status has changed, causing a harder visual effect than
the Standard cut.
SHIFT + 2 SEC = a 1 SECOND Dissolve Speed.
SHIFT + 4 SEC = a 16 SECOND Dissolve Speed.
SHIFT + 8 SEC = a 32 SECOND Dissolve Speed.
ALL SHIFT Dissolve Speeds can also be combined with ALT to prevent
advance of down going projector.
Shift ALT
The lamp in a Slide Projector does not turn on or turn off instantaneously
with the application or removal of power, because the lamp requires
fractions of a second to heat up or cool down. This is called "thermal
lag" of the lamp. The thermal lag is different for turn on than turn off.
The SHOW PRO V automatically compensates for thermal lag differences
in all dissolves and alternates. For Cut or ALT, the SHOW PRO V has
what AVL calls an "Afterburner" to remove the possibllity of any
blink effect. This afterburner also has the advantage of allowing visuals
to move at 20 CPS and have each visual reach full brilliance. However,
a lamp may not be alternated on and off 20 times per second with ALT
because the afterburner will hold the lamp on. Hence, the introduction
of "SHlFT, ALT" which removes the afterburner and allows f lashing a
lamp at 20 CPS and/or flying visuals at 20 CPS at less than full
brilliance. Additionally, the SHI FT ALT is used in the INTENSITY
CONTROLLED ALTERNATE described later in High Performance
Screen Affects using SH lFT.
Dissolve Freeze
The new SHOW PRO V can "Freeze" and hold a dissolve at any lamp
intensity. You may program this effect by commanding SHIFT with
the projector (or pro.iectors) you wish to Freeze, AND NO DISSOLVE
SPEED.

Designate which "screen" is to receive commands. A "screen" is a
projector pair when the SEOUENCE switch is at TWO, or a group of three
projectors when the SEOUENCE switch is at THREE. The Screen
Command buttons can be operated sinoly, simutaneously, or in any
combination in conjunction with black-lettered command buttons.
Cue
This buttor-r is rhe final command to execute, and must be cued before the
computer will act on any f unction entered.
Left Center Right
Designate specific projector(s) to be commanded. These buttons can be
used lrrdependently or simultaneously with any dissolve speed or pre-set
the next projectors to react to command. System Iogic always starts with
the left projector and functions in a Ieft - center - right sequence unless
commanded to do otherwise by these individual proiector controls. lf
the SEOUENCE srn,itch is at TWO, system Iogic will start with the left
projector in a left - right rotation unless commanded to do otherwise.
Forward (FWD)
ln conjur-rction with the appropriate Screen Control numbers this button
commands all proiector trays in a bank to advance simultaneously. Used
in ccnjunction with a Screen Control number and LEFT, CENTER or
RIGHT buttons, it will advance only the proiector tray(s) selected.
Shift Forward
The command "SHlFT, FWD" shifts the programmer to 20 CPS. The
programmer indicates that the cue speed is 20 CPS by lighting the amber
Mag Tape Status LED. When 20 CPS cues are played from l\,4a9 tape
into any AVL computer, the amber LED will light. NOTE: The lVlag
Tape switch should always be in "Program" when programming.
Reverse (R EV)
ln con junction with the appropriate Screen Control numbers, this button
commands all pro.lector trays in a bank to reverse simultaneously. Used
in conjunction with a Screen Control number and LEFT, CENTER or
RIGHT, it will reverse only the proiector tray(s) selected.
Shift Reverse
The conrnrand "SH lFT, R EV" shifts the programmer back to 1 0 CPS.
The new SHOW PRO V automatically shifts back to 10 CPS at POWER
ON or following HOME or RESET.

HIGH SPEED TIMING CONTROLS
PROGRAMMABLE HOME
Sta rt
With the PROGRAM Tlt\4lNG switch in the STEP position, this cue may
be entered alone or in conjunction with a screen action to program the
start of any hioh speed run or sequence. With the PROGRAM TIMING
switch in the PLAY position the computer will begin a high speed
sequence when START is commanded, executing instructions at ten cues
per second untilWAlT or STOP is commanded.
Wait 1/10
Wait 112
Wait 1
These buttons establish waiting time between commands ciuring a high
speed run. They can be used simultaneously or consecutively in any
combination to set waiting time between screen actions. When a WAIT is
commanded the computer hesitates for the designated time, then continues
performing at ten cues per second until WAIT or STOP is commanded.
When the SHIFT button is used with the WAIT commands it changes
timing:
WAIT 1/10 becomes WAIT 3/10
WAIT 1/2 becomes WAIT 7/10
WAIT 'l becomes WAIT 2
NOTE: When programmer is in the high speed mode a 1/20 SEC WAIT
time can be achieved by programming a dummy cue, ie. any AUX channel
not in use or a SHIFT FWD.
Stop
Dictates the end of a high speed sequence. STOP may be entered alone
or in conjunction with the last screen action of the sequence.
Home
Brings memory and all proiector trays to their starting points by the
shortest route and leaves the sytem in standby. Similar to RESET except
HOME becomes a part of the program and is stored in memory.
