SS 16.16 Installation and Operation Manual
INSTALLATION
Connecting The Audio Inputs, Outputs, PIP, remote control inputs and
OC/Relays:
The SS 16.16 interfaces to your audio equipment through depluggable rear panel
screw terminals. Remove each screw terminal, strip each conductor, insert the con-
ductor into the terminal and screw down the capture screw. The terminals accom-
modate wire sizes from 16 - 28 AWG solid or stranded wire. Connections may be
made to the + and - inputs for balanced operation, or to the + input and grounding
the - side for unbalanced input operation. Connections can be made to the + and -
outputs for balanced operation, or to the + output and ground for unbalanced output
operation.
The input impedance is high, 600
Ω
terminations may be installed on the connector.
It is recommended that all cables connected to the SS 16.16 be looped through fer-
rite cores to suppress RF. Surge protection with RF filtering such as the Tripp Lite
“ISOBAR 4” is also suggested for the power supply. The purchase of an inexpen-
sive uninterruptible power supply (UPS) will provide back up in case of power out-
ages. Check out our web site for lightning protection links.
Adjusting Input and Output Levels:
Once the input and output connections have been made, the input levels can be set.
The switcher is factory set for unity. Maximum input levels should be limited to
+ 27dbu. Should input levels need to be changed, they are accessible from the rear
panel. Each input trimmer has one adjustment per channel. Output adjustments
must be made internally on the main circuit board. The trimmers are labeled.
Remote Control:
The PIP inputs and open collector outputs may be connected via the rear panel
removable screw terminals. The SS 16.16 accepts momentary contact closures,
open collector or 5-volt TTL/CMOS logic levels. Open collector control is also pro-
vided. Please refer to the appendix for the connector layout.
CAUTION!
Never connect either
the + or - outputs to
ground.
CAUTION!
Installation of the
SS 16.16 in high RF
environments should be
performed with care.
Shielded cable is sug-
gested for all control,
audio inputs and out-
puts. All shields should
be tied to the “CHAS-
SIS GROUND” termi-
nal. The station
ground should be con-
nected to the chassis
ground screw (CH1)
located behind J1 as
viewed from the rear.
