DB-25 Audio Connections
SF-16M units may be linked together to create systems up to 64 outputs (
see page 16 for hookup details.
) The DB-25
ports streamline this type of expansion, and also serve as a connection from other Audio Authority matrix systems.
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 (
Figure 3
).
2. Direct input from an Audio Authority audio matrix:
The SF-16M may serve as an amplifier for Audio Authority audio
matrix switchers such as the ADX-0808/ADX-1616 and the HLX 2278 audio output card (
Figure 4
). 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.
) If the volume levels will be controlled from the
HLX or ADX matrix, turn up all SF-16M outputs to maximum volume (-0dB.)
CONNECTIONS - Source 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
provides examples of all configurations.
NOTE: Specify input configurations using the PC Setup Utility (page 22)
or the front panel menu (page 17.)

About Y Adapters:
To create a mono
signal from a stereo source, Audio
Authority recommends using the SF-16M
DSP for optimal audio quality, but when
only one RCA input jack is available, a
y-adapter may be used.
Figure 1.
Any Stereo input may be converted to two mono inputs using PC Setup Utility or Front Panel Controls.
