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 first SF-16M chassis. (See figure 2 below).
2. Direct input from an Audio Authority audio matrix: In scenarios where the SF-16M is serving as an amplifier 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 amplified outputs. The HLX or ADX provides all of the matrix switching (See figure 3 below).
SF-16M CONNECTIONS - Audio Inputs
RCA Line Inputs
The SF-16M includes 16 RCA audio inputs that can be configured as mono, stereo or a combination of both mono and
stereo. Figure 1 shown below provides examples of all configurations.
NOTE: It is important that all physical input configurations are entered into the SF-16M programming, using the PC con-
figuration software or the front panel system menu.
