A.Power. This power module accommodates power ranging from 100–240VAC, 50/60Hz. No switching is required.

B.Inputs A–D.These connectors are used with line-level inputs. Line level inputs can be mixed in any combination with the gated inputs to any of the eight outputs. Nominal input is 0dBu. Mix level can be easily set for each non-gated input.

C.Outputs A–D,1–8.These connectors allows eight line-level outputs to be connected to the unit. Outputs can include video codecs, AP800s, AP10 Telephone Interfaces, and VCRs. These outputs can be configured to contain any combination of gated and non-gated inputs. The nominal output level is 0dBm.

D.Mics 1–8.Up to eight mic/line-level inputs (selectable) can be connected using the three-terminal Phoenix connector(s).

E.G-Link In, Out. These RJ-45 connectors are part of the AP800’s high-speed digital bus network, which passes audio between units.

F.RS-232.This female DB-9 serial port is for connection between the AP800 and a PC, modem, or other custom remote control. For serial communications protocol, see Appendix F, page 39.

G.Control/Status A and B. These two DB-25 connectors are used to interface parallel control to the AP800. Most of the pins on these connectors can be programmed to perform any function via a closure to ground. For pinouts, including a description of the default settings, see Appendix D on page 36.
