DB-25 Audio Connections
The DB-25 input on the SF-16M serves two purposes:
1. Source audio link between SF-16M units: When multiple SF-16M units are linked together, the DB-25 audio input
receives source audio from the DB-25 audio loop output of the previous SF-16M. The source audio originates from the
RCA audio inputs or the DB-25 audio input of the rst SF-16M chassis. (See gure 2 below).
2. Direct input from an Audio Authority audio matrix: In scenarios where the SF-16M is serving as an amplier for
Audio Authority audio matrix switchers such as the ADX-0808/ADX-1616 and the HLX 2278 audio output card (See Illus-
tration below). In this scenario, the SF-16M receives all audio content from the ADX or HLX and passes the audio through
to the amplied outputs. The HLX or ADX provides all of the matrix switching (See gure 3 below).
SF-16M CONNECTIONS - Audio Inputs
RCA Line Inputs
The SF-16M includes 16 RCA audio inputs that can be congured as mono, stereo or a combination of both mono and
stereo. Figure 1 shown below provides examples of all congurations.
NOTE: It is important that all physical input congurations are entered into the SF-16M programming, using the PC con-
guration software or the front panel system menu.
