1. OVERVIEW

1.1 Features and Capabilities

The Mackenzie MacFi-mp family is the most cost effective series of MP3 Digital Audio Record / Play Systems available for industrial usage. Backed by Mackenzie’s years of system design experience, MacFi-mp offers a great deal of functionality in a compact and inexpensive package.

Messages are user recordable via microphone or line input through a straight forward user interface located directly on the unit. Simple parallel controls for 8 messages are available on terminal connectors. Record and Stop inputs and a Play relay output are also accessible via terminals.

The MacFi-mp offers up to 99 messages and 40 minutes of MP3 audio. MP3 supports up to 15kHz bandwidth and 80 dB of dynamic range. All 99 messages are accessible from the user interface on the MacFi-mp with 8 remote start inputs accessible via the remote activation pluggable terminal. Dynamic Message Length (DML) technology has been incorporated in the MacFi-mp 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.

The MacFi-mp retrieves stored audio data from non-volatile flash memory, eliminating the need for battery backup, and delivers superb sound quality.

The MacFi-mp offers several different playback modes to accommodate different applications. Standard, Play once per closure, Play while active, and Retrigger allow the MacFi-mp to be used with existing on site control circuitry. Message repetition and delay between message settings 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-mp’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.

Play Method

Defines playback mode of Message sequences. Message sequences are comprised of the message material, number of plays and delay between plays.

Standard operation - details

below

Play one sequence per

closure -details below

Play while active - details

below

Re-trigger - details below

Standard Operation: A momentary contact closure at a start

input 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.

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-mp 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 MacFimp, causing each of the messages to be played in the order they were received. The queue length is 16 sequences 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 starts and continues 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 stop playing that message.

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 of the highest priority 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 of the highest priority will be played. This mode does not support queuing.

Play Next

Enabling Play Next allows Start 8 input (Connector 1, Pos. 9) to initiate playback of the next valid message sequence. The first start activation after power on will play message 1. All operation modes are supported and other start inputs (1 - 7) are disabled.
