DESCRIPTION
Professional prop builders know a secret: audio is more than half of the experience of a high-quality prop. Until
now, consumer-level audio boards lacked some professional features – things like quality amplification, as well as
the ability to mix a stereo signal (to mono) right on the board. The AP-8 solves this problem, providing quality
audio and amplification in a small format; a format perfect for amateur and professional prop builders alike. Need
more than eight sounds? No problem – the AP-8 is addressable allowing up to four units to be attached to the
same host (serial) connection.

- Page 1 Need more than eight sounds? No problem – the AP-8 is addressable allowing up to four units to be attached to the same host (serial) connection.
- Page 2 AP-8 or the host controller. Connections – Power and Speaker Connect a 12-24 volt, 1 amp DC power supply to the AP-8. Power to the AP-8 is input through a 2.1 mm, center- positive barrel connector.
- Page 3 "!AP8", address, command { , data } … where “!AP8” is the preamble that allows the AP-8 to exist on the same communications line as other devices (e.g., DC-16, RC-4), address is the board address set with jumpers on ID0 and ID1, command is a single character command designator, and data is any value that may be required by command.
- Page 4 NOTE: The AP-8 “P” and “X” commands have “all call” capability. When the address byte for these commands is set to 255, any AP-8 on the communications line will respond to the command, but no status byte(s) will be returned.
- Page 5 AP-8 is accomplished through an audio connection between a PC (or similar audio source, e.g., a CD player) and the AP-8. For most applications, the following process is used to record one or more audio segments: 1.
- Page 6 (or more) segments then you reduce the number of sounds you can play with the AP-8. If, for example, you have a sound effect that is 10 seconds long and you want to place it into segment 0, this is no problem.
