Connecting the unit
To connect the AP400
1. Place the unit in a standard 19-inch rack and attach it securely.
2. Connect the telephone line from the wall jack to the RJ-11C Line jack [I].
3. Plug the telephone set into the RJ-11C Set jack [I].
4. If you are using a custom controller for control and status, connect it to the
Control/Status port [G].
If you are using an external RS-232 controller or the AP IR remote,
connect it to the RS-232 port [F].
5. Wire the inputs and outputs to the AP400 using the provided three-terminal
Phoenix push-on connectors. These connectors are designed for easy wiring;
simply insert the desired wire into the appropriate connector opening and
tighten down the top screw.
• Mic 1–4 [D] Mic or line level inputs
• Inputs A–D [B] Line level inputs only
• Outputs A–D, 1–4 [C] Line level outputs
When connecting, use the screened legend on the back of the unit;
overlapping from one channel to another can cause improper operation.
6. Connect the speaker wire to the + (red) and – (black) binding post
connectors. A 4–16Ω speaker can be directly connected to the AP400,
eliminating the need for an external power amplifier.
7. Plug in the AP400 to complete the installation. The power output [A] will
operate at any level between 100–240VAC and 50–60Hz.
If you are installing only one AP400 and are not connecting it to any other AP units,
you have completed the hardware installation.
