1 OVERVIEW
1.1 Features and Capabilities
The Mackenzie MacFi system is the most cost effective series of solid state digital
audio record / playback systems available to the industry. Backed by Mackenzie’s
years of system design experience, MacFi offers a great deal of functionality in a
compact and inexpensive package.
The MacFi retrieves stored audio data from non-volatile flash memory, eliminating
the need for battery backup, and delivers superb sound quality.
The MacFi is offered in either 8 or 16 minute versions and supports up to 6.5kHz
bandwidth and 60 dB of dynamic range. System capacity is 8 randomly and instantly
accessible messages. Dynamic Message Length (DML) technology has been
incorporated in the MacFi allowing each of the messages to be of different duration.
DML also provides for replacement messages to be a different length than the
original, maximizing memory efficiency and compatibility with future applications.
Messages are user recordable via microphone or line input and straight forward
user interface located directly on the unit. Simple parallel controls for the 8
messages are available on terminal connectors. Record and Stop inputs and a Play
relay output are also accessible via terminals.
The MacFi offers several different playback modes to accommodate different
applications. Play/repeat, Play once per closure, Play while active, and Retrigger
allow the MacFi to be used with existing on site control circuitry. Message repetition
and delay between messages are user selectable as well.
The space saving built-in 4 watt power amplifier is perfect for most direct to
speaker applications as it eliminates the need for additional hardware.
The MacFi’s small size, industrial construction and the absence of moving parts
make it ideal for automatic unattended operation, especially in harsh environmental
or mobile conditions. An optional 1U rack mount adapter is also available.

2 INSTALLATION & CONFIGURATION
This section provides complete instructions for mounting the MacFi, 8 Message Digital Audio
Record / Play System on a wall or table. It also illustrates all interface requirements to
auxiliary equipment, including inputs and outputs. Configuration switch settings are provided.
2.1 Installation Steps
These are the general steps for installation.
1. Find a space on the wall or table. For table top applications, install included
rubber feet. Allow approximately 6 inches in front of, and 6 inches above the
unit for user access to the controls and wiring.
2. Mount the unit to the selected place with its wiring at least 18” away from
power supply or other equipment that generates electrical noise.
3. If you are using the optional power supply, make sure there is a standard
electrical outlet available.
4. Connect audio inputs and outputs.
5. Connect control inputs and outputs.
6. Set DIP switches to the desired operation.
7. Connect and apply power.
8. Test unit operation.

2.2.2 Configuration Switches
8 position DIP Switch: UP ( ) position is OFF.
DOWN ( ) position is ON.
This user adjustable dip switch is provided to allow the user to tailor the operation
of the MacFi to meet their demands. NOTE: This dip switch is read by the
system only upon power up. Changing the position of the dip switch
while the module is powered up will have no affect on the operation
of the system.
Standard Operation: A momentary contact closure causes the device to play
one sequence of the message corresponding to that input. A sequence is specified
by the number of message plays and the amount of delay between each message, as
selected by the dip switches. If a contact is maintained active, the system will
continuously play that sequence repeatedly until the input is released at which time
the system will finish the current playback sequence and then stop.

Number of Plays
For applications where mes-
sages need to be repeated due to
ambient noise or for clarity.
Global setting for all messages.
When message is activated, it
will play the programmed
number of times.
Play activated message one time
Play activated message two times
Play activated message three times
Play activated message four times

Delay Between Plays
Messages played immediately
after one another can be con-
fusing to the listener. Allowing a
delay time can make the play-
back easier to understand.
Global setting for all messages.
One second delay between plays
Five second delay between plays
Ten second delay between plays
Thirty second delay between plays

If multiple inputs are held active the system will play one sequence of the first
message and then cycle through any other active messages sequentially, based on the
order which they were activated. The message corresponding to the lower input
number will have priority should multiple inputs be activated at exactly the same time.
If a momentary contact closure is provided, for the same or any other message,
while a sequence is playing and it is released prior to the ending of the current
message play, it will be ignored.
Play one sequence per closure: If an activation input is maintained, the
system will only play the message sequence one time. The MacFi will wait for the
input to go inactive for 100ms before it will recognize that input for subsequent
message activations. Other play activations will be serviced normally, even with
another input held active indefinitely.
This mode supports message queuing. Message queuing allows the user to input
multiple, momentary activation’s to the MacFi, causing each of the messages to be
played in the order they were received. The queue length is 16 messages maximum,
including the message which is playing. A single message may be queued more than
once. Any activation issued once the queue is filled will be ignored.
A stop command will stop the message which is currently playing, and when
released, the next message in queue will begin playing.
If multiple inputs are held active and maintained, the system will play each
message sequence once then stop.
Play while active: Upon receiving a maintained input control signal, the
message will continue to play for the duration which the control signal is held
active. If the input signal is removed prior to the end of the message sequence, the
system will immediately abort the playback sequence.
If the input is sustained after the current sequence has completed, another
sequence will be initiated. If the input is removed during the delay time after the
final message play in the sequence, another sequence activation will not occur.
If multiple inputs are maintained active while in this mode, the system will only
play the active message and then repeat. This mode does not support queuing.
Re-Trigger: This mode allows playing messages to be interrupted by another
incoming message, or another activation of the same message. If a message is
currently playing and another message activation is received, the currently playing
message will be terminated and the new message will be played.
A maintained message activation will only play the sequence one time and then
stop. If multiple inputs are activated at exactly the same time, only the lower
numbered message will be played. This mode does not support queuing.
