- MACs Eight Bit Digital Audio System -

- A System Overview -

The MACs Eight Bit Digital Audio System has been developed to meet all
of your needs for Digital Audio Repeaters. The following repeaters are avail­able:

¥ AB-100 Digital AudioBrick: Complete stand alone Digital Audio

Repeater. It comes in a 5Ó x 12Ó x 2-1/2Ó aluminum box which can
be mounted wherever you need to put it. Holds up to 255 different
sounds and can be expanded almost without limits. The AB-100 can
be set to play continuously or only when triggered. It includes a UL
listed power supply. A 12 to 24 VDC power supply is available for
mobile installations.

¥ AB-Clock: As above, but with real-time clock option installed.

Schedules in the AB-Clock can be configured to play different
sounds on:

¥ Quarter hours
¥ Half hours
¥ Three-Quarter hours
¥ Full hours
¥ Tolling of the hours on full hours
¥ Any of thirty special times for each of the seven days of the week
¥ Any of thirty special times every day of the week (optionally only

on weekdays)

¥ Tick and Tock sounds which alternate with each other with a one

to ninty-nine second delay between each.

¥ DR-50: Card cage mounted MiniRepeater that holds a single

Eprom. These are especially well suited in installations where you
need many relatively short audio sources. Examples are ride-through
attractions, shooting galleries, miniature golf courses, and museum
displays. Up to 32 of these cards can be installed in each 1-3/4 inch
tall CC-3250 card cage. A DR-50 can be set to play continuously or
only when triggered. The DR-50 circuitry is identical to the AB-50.

¥ AB-50: As above, but comes in its own 4Ó x 5Ó x 1Ó aluminum case.

The AB-50 can be set to play continuously or only when triggered.
These are used where you need just a single short audio source. It
runs from the included 12 VAC power supply. The AB-50 circuitry is
identical to the DR-50.

Each of these can be used alone or as part of your overall audio system.
When used together, all you need to add to make a complete audio sys­tem are the power amplifiers and speakers. If higher bandwidth and dy­namic audio ranges are needed, you can use our DR-3000 series of sixteen
bit Audio Repeaters. These feature CD-Quality sound and more audio pro­cessing and control options than our eight bit repeaters.

What is a Digital Audio Repeater?:

A Digital Audio Repeater is a solid state replacement for loop and car­tridge tape decks. It meets the demanding requirements for professional
voice message, high quality music, and sound effects systems.

Because it is completely solid state, a Digital Audio Repeater never re­quires any maintenance. A sound which is recorded on a Digital Audio
Repeater will sound just as good twenty or thirty years from now.

Each AB-100, AB-Clock, AB-50 or DR-50 is a complete Digital Audio
Repeater. Their features include:

¥ Each card is a single complete audio playback system (except for

power amplification and speakers).

¥ Any sound that can be recorded can be digitized into a Digital

Audio Repeater. This includes any type of chimes, bells, voice an­nouncements, music, alarms or sound effects.

¥ Message length is virtually unlimited on the AB-100 and AB-Clock.

Memory expansion cards can be added as needed. AB/DR-50s
each hold a single Eprom.

¥ Bandwidths of up to 15 KHz supported (35.1 KHz sample rate). This is

roughly equivalent to a new cassette audio tape. Each card will also
reproduce at 10, 7.5, 5, 4, 3, and 2 KHz bandwidths as well.

¥ Dynamic range of up to 72 dB, again roughly equivalent to a new

cassette audio tape.

¥ Up to 255 different messages can be stored on each repeater. On

an AB-100, any of these can instantly be accessed through the RS­485 serial port or switch inputs. This lets you easily build interactive
audio systems by just adding the buttons to select different spiels! Up
to 99

1

of these can instantly be accessed by the AB-Clock through
the switch inputs. Multiple spiels can be accessed sequentially in the
AB/DR-50s.

¥ An AB-100 or AB-Clock can actually stop using any memory at all if

an instant of silence occurs.

¥ Two opto-isolated switch inputs, as well as a parallel auxiliary port

and RS-485 serial port on each card (AB-100 & AB-Clock only).

¥ OP-100 optoisolator available for auxiliary port. 1/4 J6 input is com-

patible with all our animation systems (AB-100 & AB-Clock only).

¥ Operating hours for the AB-Clock can be set for 24 hours a day or

specific times for each day of the week.

¥ The AB-Clock is factory laser trimmed to within +/- 10 PPM. A lithium

battery provides protection against power failures.

¥ Clock can be programmed for daily, weekly, monthly or annual ad-

justments to correct for slow or fast timekeeping.

¥ All AB-100 & AB-Clock configuration is done through the serial port

with easy to use menus. Configuration is stored in nonvolatile
EEprom memory. AB/DR-50s are configured using dipswitches.

¥ One optically isolated status output for remote ÔrunningÕ indicators

(AB-100 & AB-Clock only).

1 Although the AB-Clock can hold up to 255 different spiels, the software in the AB-Clock

limits your access to the first 97 messages from the two start inputs, push button on the
front, or keyboard. The real time clock can trigger any of the first 98 spiels for the
chimes and tolling of the hours. It can select and play any of the first 31 spiels from the
special show tables. Only the optional 1/4 J-6 input can access all 255 messages.

¥ Volume, Bass and Treble controls on every card.
¥ You can use any number of cards in a system to provide any num-

ber of simultaneous audio tracks.

To record a sound into a Digital Audio Repeater, a master (tape, CD,
DAT, video tape) of the sound is played into a Macintosh or IBM compatible
computer which has some sort of sixteen bit sound card installed. This takes
the original audio and turns it into digital computer data. This data is then
run through the SNDCMP8 utility program we provide and 'burned' into
computer memory chips called Eproms. These are plugged into the Digital
Audio Repeaters. From this point on, the repeaters can play back this sound
whenever they are told to. Since the sound is stored on the repeater in com­puter memory chips, it will never change or require any service of any kind.
Any tape deck would require regular cleaning and lubrication of the tape
heads and moving parts, as well as their regular replacement.

The SNDCMP8 software for digitizing the audio into the AB-Clock is avail­able from Gilderfluke & Company. If you would prefer to have us digitize
your sounds then simply send your master audio recording to us. When
sending audio masters to us to digitize, DAT or CD recordings are preferred.
1/4Ó quarter track at 15 IPS reel to reel or a cassette with Dolby B/C encod­ing can also be used, but be aware that any tape hiss from these original
masters will be permanently recorded into the AB-Clock.

Gilderfluke also has libraries of prerecorded sounds and sound effects
which we can record into the AB-Clock for you if you would like.

Each AB-100 or AB-Clock can store up to 255 separate messages in its
memory. Each of these can be any length from 1/35th of a second on up.
Each of these individual messages is known as a 'spiel'. To access these in­dividual spiels on a card, you can use the serial port interface to the audio
system or the AUX PORT available on each card. Any spiel on any card can
be played through or looped at any time.

When using the AB-Clock to select and play spiels, the order of priorities is
as follows. If it finds any sound it should play it will skip the remainder of the
checks until the next time through. This means that if a special show is
scheduled for today, it will take precedence over any weekly shows or the
tolling of the hours. Everything has priority over the tick and tock sounds:

1) Once each minute checks for any special shows to play for today.

2) Once each minute checks weekly schedule for any special shows to
play.

3) Once each minute checks to see if it it time to toll the quarter, half,
three-quarter or full hour.

4) Once each second checks to see if it is time to make a tick or tock
sound, but only if it is not already making any other sound.

Our Digital Audio Repeaters are intelligent. They know how to 'downshift'
their bandwidths to whatever bandwidth the audio was recorded at. If
there is a moment of silence in your recording, An AB-100 or AB-Clock will
actually stop using any memory at all until the sound starts up again.
Because of this, our systems are able use far less memory for an equivalent
bandwidth. They are also able to play back both low and high bandwidth
sounds from the same Repeater card. The Digital Audio Repeaters each
check on how much memory they need to use and adjust their speeds as
often as thirty-five times each second.

Although this 'downshifting' saves the amount of memory you need to
use, it can make it darned difficult to estimate the number of Eproms your
recording will need until it has actually been digitized. The following charts

Each AB-100 or AB-Clock holds sixteen Eproms. If your recording needs
more space than this, you can add memory expansion cards to the
Repeater cards. Each expansion card holds another thirty-two Eproms.
Each AB-100 or AB-Clock can support unlimited amount of data storage.
The only limitation is the physical mounting of the memory expansion cards.
In the AB-100 or AB-Clock there is room for up to three memory expansion
cards if you plan to leave the lid on. With the lid off, the sky is the limit.

Each DR-50 or AB-50 MiniRepeater holds one Eprom. There is no expan­sion available on these repeaters.

The AB-100 or AB-Clock can support any type of Eprom memory chips
from 27C512 up to 27C080. Each AB-100 or AB-Clock must be told what
type of memory chips are being used. This is done in the configuration
mode. The AB/DR-50s support memory chips from 27C010 through 27C080.

The Digital Delay feature allows the AB-100 or AB-Clock to delay the start
time of any audio track. Delays can be anywhere from approximately
1/35th of a second to about 1/2 an hour from the time it is given a start
command. The delay will occur any time a start command is received after
a AB-100 or AB-Clock has received a reset command. In many applications
this allows a single start signal to be used for a number of the Digital Audio
Repeaters. The actual start of the spiels is then adjusted in the field as need­ed. The 'DELAY' LED on the front of each AB-100 or AB-Clock shows when it is
in delay mode before starting its spiel.

When a AB-100 or AB-Clock is in looping mode, the delay will be inserted
between each iteration of the playback loop. In normal looping mode a
single spiel is played repeatedly. If the LOOP ALL option is on, then all the
spiels on the card will be played sequentially, with the delay inserted be­tween each one.

Both the 'start' inputs and 'running status' output for the AB-100 or AB­Clock are optically isolated from all other parts of the system. Connections
are made through four screw terminals. They can be configured to run ei­ther from the isolated 'Dirty' power supply or from external power. Eight ad­ditional inputs are available through the AUX PORT on each card. These are
used to select specific spiels from manual push buttons or switches. The AUX
PORT can be configured to select 'one of eight' with individual switch clo­sures to each input or 'one of 255' with a binary spiel select to the inputs.

The AB-100 or AB-Clock checks both the rising (switch closure) and falling
(switch opening) edges of each input. This allows you to configure a AB-100
or AB-Clock to do one action on one edge of a switch opening or closing,
and then take a different action on the opposite edge. An example of this
feature would be if you told the AB-100 or AB-Clock to start on finding a clo­sure on one of the inputs, and then stop when the same input is opened
again.

The two optically isolated inputs on an AB-100 and the push button on
the front of the case can be configured to:

1) MUTE AUDIO

2) HALF MUTE AUDIO

3) UN-MUTE AUDIO

4) RESET REPEATER TO START

5) STOP REPEATER IMMEDIATELY

6) START REPEATER

7) START REPEATER LOOPING A SPIEL

8) STOP REPEATER AT END OF CURRENT SPIEL

The two optically isolated inputs on an AB-Clock and the push button on
the front of the case can be configured to:

1) do nothing

2) select and play any spiel numbered 1 to 97

3) select and play whatever the next spiel in line is

4) prevent the clock from starting any spiel (ÒmutingÓ)

There are several options which you can select for start commands which
come while the AB-100 or AB-Clock is still playing the last spiel. You can tell
the AB-100 or AB-Clock to:

1) Ignore early starts.

2) Jump immediately to the beginning of the current spiel.

3) Jump immediately to the beginning of the next spiel.

4) Ignore the early start for now, but save and do it as soon as the current spiel is

done.

Also available on all AB-100 and AB-Clocks is a single optoisolated status
output. On the AB-100 this output is active whenever a spiel is being
played. On an AB-Clock it can be configured to:

¥ pulse once each minute

¥ pulse once each second

¥ turn on whenever the AB-Clock is making sound

This output can also be pulsed from the keyboard when you are configur­ing the AB-Clock. The one pulse per minute setting is used to run ÔregulatorÕ
or ÔremoteÕ type clock faces. The one pulse per second setting as well as the
single pulse command are normally used for setting any clocks which are
slaved to the AB-Clock.

Adjustments:

The following adjustments are available on all of our Digital Audio
Repeaters:

Volume: This control sets the volume of the output from the Repeater.

This adjustment is available on the AB-100, AB-Clock, DR-50 and AB-

50.

Treble: This control is used to adjust the level of the high end of the

Shelving Equalizer. This adjustment is available on the AB-100, AB­Clock, DR-50 and AB-50.

Bass: This control is used to adjust the level of the low end of the

Shelving Equalizer. This adjustment is available on the AB-100, AB­Clock, DR-50 and AB-50.

Inputs:

The 'Manual Start' Button on the front of each AB-100 or AB-Clock feeds
directly into the Digital Audio Repeater's circuitry, and so doesn't light the
'Start' LED. Other than this one detail, the Manual Start Button acts just like
any other 'Start' input. It can be configured identically.

ÔSet ClockÕ Button: An AB-Clock adds two additional recessed buttons
that are used to check and set the clock. You must use the end of a pencil
or paper clip to press this button. This button is used to set the clock. Each
time you press it, the minutes will be incremented by one. If the ÔCheck
DateÕ Button is held in when this button is pressed, then the hours will be in­cremented.

ÔCheck DateÕ Button: An AB-Clock adds two additional recessed buttons
that are used to check and set the clock. You must use the end of a pencil
or paper clip to press this button. This button is used to check the date. The
first single digit is the day of the week (1-7). If it is pressed in and held, the
ÔSet ClockÕ Button will advance the hours of the clock each time it is
pressed.

ÔDefault ReloadÕ Button: The AB-100 and AB-Clock have a button hid­den inside the case which is used to reload the default configuration on the
repeater. It is labeled as DIPSW1-2. To use it you must:

a) Power down the AB-100 or AB-Clock. You should always do this by

unplugging the power supply from the wall rather than unplugging
the 5 pin DIN connector at the AB-100/AB-Clock.

b) Remove the AB-100 or AB-Clock case top.

c) Press and hold the button down while plugging the power supply

back into the wall.
d) After the repeater reboots, release the button.
d) Reassemble the AB-100/AB-Clock.

The defaults are now reloaded. You can reconfigure the AB-100/AB-Clock

through the serial port at address 00h operating at 9600 baud, no parity.

Indicators:

The 'Running' LED on the front of each Digital Audio Repeater shows

when each is currently running. When this LED is lit on the front, then sound
should be coming out the back. This indicator is available on the AB-100,
AB-Clock, DR-50 and AB-50.

The 'Start' LED on the front of each AB-100 or AB-Clock is actually a com-

bination of the two opto-isolated start inputs. This shows the actual start in­puts' status as it is seen by the Digital Audio Repeater, and not a processed
version of them.

The ÔDelayÕ LED on the front of each AB-100 or AB-Clock shows when:
a) The repeater is performing a delayed start or the delay between

each iteration of a loop.
b) The repeater is skipping over a part of the audio that has been en-

coded in the Eproms as a moment of silence. You can tell when the

repeater is doing a Ôrunning delayÕ because the 'Running' LED will

also be lit at the same time.
LCD Display: AB-Clocks also have a LCD Display added to them which

is used to display and set the current time and calendar. This display nor­mally shows the current time in twenty-four hour ÔmilitaryÕ time format.
Following the time, ÒdsÓ will be displayed if the clock is currently using day­light savings time. The clock will also display ÒmuteÓ if an external input is
keeping any sound from playing or ÒrunÓ if the time is currently between the
hours that have been set for automatic tolling.

Pressing the ÔCheck DateÕ Button will cause the display to momentarily

switch to displaying the day (1=Sunday through 7= Saturday) and date
(mm/dd/yy).

Line Level Output:

The output of the AB-100 and AB-Clock is a +10 dB balanced output.

The connection is through a 1/4Ó stereo phone plug. If this output is operat­ed in single ended mode, the unused output MUST be grounded. If it is not,
then the output will be excessively noisy. As shown by the illustration on the
end of the case, using a mono 1/4Ó phone plug will automatically ground
this unused output in single ended applications. Use a 1/4Ó stereo phone
plug only in balanced applications.

Aux. Port & 1/4-J6 Input:

The AUX PORT is used to select a specific spiel on a single AB-100 or AB-

Clock. You will need to select the OP-100 AUX PORT OPTO-ISOLATOR option if
you want to use the Aux. port. The input to the Aux. Port is the same 1/4 J-6
connection used by all of our Animation Control Systems. If you are using a
source other than our Animation Control Systems, the connections are as

JP-11 is used to select whether the 1/4-J6 input is to be run from external

power or from the same power supply as the AB-100 or AB-Clock. With JP-11
in the Left position, the inputs use same power supply as the AB-100 or AB­Clock. Any switch closure between the data bits and ground will trigger a
spiel. With JP-11 in the Right position, an external source of power is needed
by the 1/4-J6 input. This is the safer method of operating this port, since any
spikes on these input lines wonÕt be coupled into the AB-100/AB-Clock
through its power supply. The input to the 1/4 J-6 connection is simply eight
opto-isolators. Each input is equivalent to turning on a LED with a 4.7 Kohm
in series.

Start Inputs and Status Outputs:

Both the 'start' inputs and 'status' output for the AB-100 or AB-Clock are

optically isolated from all other parts of the system. Connections are made
through four screw terminals on the back of the AB-100 or AB-Clock. They
can be configured to run either from the same power as the AB-100 or AB­Clock or from external power supply. The jumper selection and connections
for these two modes of operation are as follows:

In the vast majority of cases, the ÔEXTERNALÕ power configuration is pre-

ferred, as it isolates the audio circuitry inside the AB-Clock from any possible
interference from the wires leading to your switches.

Power Supply:

Five position 180¡ DIN connector 2. Plugging and unplugging this con-

nector from the AB-100/AB-Clock is not recommended while the power sup­ply is plugged in. You should always unplug the power supply from the wall
before plugging/unplugging the 5 pin DIN connector at the AB-100/AB­Clock. The pinout for the Power Supply connector is as follows:

SIGNAL NAME:

Pin #1 Ground
Pin #2 N/C
Pin #3 + 5 VDC
Pin #4 - 12 to 15 VDC
Pin #5 + 12 to 15 VDC

RS-422 Serial Port:

For AB-100 and AB-Clocks, a six position RJ-11 (modular telephone style

connector) is used for the serial data. Facing the end of the cable with the
release latch upwards, its pin out is as follows:

BLACK - SERIAL DATA OUT FROM REPEATER

RED + SERIAL DATA OUT FROM REPEATERS

To communicate with the AB-100 and AB-Clocks through the serial port,

you can use just about any computer or terminal that has a serial port on it.
Some newer computer designs, like the Apple Macintosh, come with serial
ports that are directly compatible with the RS-422/RS-485 signal levels the
AB-100 and AB-Clocks want to see. These signal levels are close enough to
be used with the RS-232 signal levels found on most older computers (like
all IBM PCs and compatibles). They can be attached with only a simple

adapter cable, so long as the wire isn't too long and there arenÕt too many
AB-100s and AB-Clocks attached to the same serial line. To gain the full ad­vantage of the RS-422/RS-485 signal levels (multidrop networking, distances
of up to a mile) you will need to use a signal level adapter.

To cross wire the RS-422/RS-485 signals from the digital audio system to

the RS-232 serial port of an IBM compatible, cross connect the signals as

- AB-100 AudioBrick Configuration -

To configure the system through the serial port, you need to connect the

system just as you do for any serial communications (see the 'AB-100
AudioBrick Serial Port Commands' section of the manual). The configuration
mode is entered by the command:

"m" (5AA5) (TRACK#)

This command will bring up the following menu from the Repeater which

was addressed.
EXAMPLE: to bring up the configuration screen for a card addressed as

Ôtrack 00Õ (this is the normal default configuration address when a Repeater
is shipped): m 5 AA500

This would bring up the following configuration screen (the screen shown

is the default configuration):

Enter command- _

The (5AA5) part of the command is a key to keep this mode from being
inadvertently entered. The card addressed by the TRACK# will put a config­uration menu on the screen. When this mode is entered by any card, it dis­ables all of the other serial commands on all the cards in the system. As with
the normal serial command mode, the upper and lower 'case' of all input
is important. An 'a' is a command while an 'A' is a number. All numeric val­ues are entered in HEX (0 - 9, A - F).

If another command is entered while the last command is waiting for
additional input, the new command will be started. If at any point you
enter a command in error and it is waiting for additional input, you can
leave the command by entering an <ESC>ape key. With the exception of
the GROUP ENABLE and PA ZONE ENABLE commands, this will leave the origi­nal configuration unaltered. These two commands will only be changed up
to the point where you <ESC>aped.

If you want to keep a hard copy printout of the current configuration of

any card, you should use the <ESC>ape key to redraw the screen while
saving the print in the modem program running on your computer. This file
can then be printed out at any time.

Note that only one card in the entire system is allowed to be in configura­tion mode at one time. For this reason, if you try to put a card which doesnÕt
exist into configuration mode, not only will you not see a configuration
screen from that nonexistent card, no other card in the system will want to
listen to you until you take the nonexistent card out of configuration mode.
To do this, type a: x n

The other cards will then start listening to you again.

The AB-100 and AB-Clock have a button hidden inside the case which is
used to reload the default configuration on the repeater. It is labeled as
DIPSW1-2. To use it you must:

a) Power down the AB-100 or AB-Clock. You should always do this by

unplugging the power supply from the wall rather than unplugging

the 5 pin DIN connector at the AB-100/AB-Clock.
b) Remove the AB-100 or AB-Clock case top.
c) Press and hold the button down while plugging the power supply

back into the wall.
d) After the repeater reboots, release the button.
d) Reassemble the AB-100/AB-Clock.

The defaults are now reloaded. You can reconfigure the AB-100/AB-Clock

through the serial port at address 00h operating at 9600 baud, no parity.

"a" Enter Track Number:

This command is used to tell the card which addresses it should respond

to from the serial commands. No two cards in the system should have the
same address assigned to them. When loaded with the default con­figuration, the address assigned to a card is 00. If more than one card is
used in the system, they should be plugged in one at a time and have their
