Audio Connections
1. Input from a single source or switcher:
For installations where there is only one source at a time for all SF-16B
outputs, set Switch 2 to Bus Input and connect the source to Inputs 1 and 2.

RCA Line Inputs
The SF-16B includes 16 RCA audio inputs in
stereo pairs, and as an alternative, a quick
connect input using a DB-25 cable. If used with
a matrix preamp, all inputs correspond to like
numbered outputs, and 1:1 Input setting should
be used. If used with a single source or with
a switch, use Bus Input setting, and connect
Input A (1 and 2) only.
2. Input from an Audio Authority audio matrix:
For installations where the SF-16B is serving as an
amplifier for Audio Authority audio matrix preamplifiers
such as the ADX-0808, ADX-1616 (Figure 4) or the
HLX with 2278 audio output card (Figure 5).
In these configurations, the SF-16B receives all audio
content from the ADX or HLX and passes the audio
through to the corresponding amplified outputs. The
HLX or ADX provides matrix switching, volume control,
equalization, tone and balance.
One ADX-1616 supports two SF-16B amplifiers, and
the HLX platform can be configured to support up to
twelve SF-16B amps, one for each audio output card.
