SS 4.1 Plus Installation and Operation Manual
INSTALLATION
Installation Guidelines
It is recommended that all cables connected to the SS 4.1 Plus 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 transformer. The purchase of an inex-
pensive uninterruptible power supply (UPS) will provide back up in case of power
outages. Check out our web site for lightning protection links.
The SS 4.1 Plus is simple to install. The signal inputs, outputs are connected via
plug-in euroblock screw terminals. Installation of the SS 4.1 Plus consists of seven
steps:
1. Inspection
2.
Removal of the source termination resistors, if applicable
3.
Bench test and option set-up
4.
Mount the unit in a rack (RA-1), desktop or wall
5.
Connect your equipment to the unit
6.
Label the front panel switches
7.
Serial operation, if applicable
STEP 1: INSPECTION
Please examine your SS 4.1 Plus carefully for any damage that may have been
sustained during shipping. If any is noted, please notify the shipper immediate-
ly and retain the packaging for inspection by the shipper. The package should
contain the SS 4.1 Plus, this manual and/or CD (the manual may be downloaded
from our web site), 9 VAC @ 1-amp transformer, reversed modular cable, 9-pin
female “S9” D-Sub adapter and audio and remote control mating connectors.
STEP 2: SOURCE TERMINATION RESISTOR REMOVAL
Input sources that are
NOT
selected are terminated with a 10K W resistor. If you
do not require this load applied to the deselected sources, it may be removed from
each channel. Each channel has a pair of resistors. Removal information: Channel
1 = R 8 & R9. Channel 2 = R10 & R11.
Channel 3, R12 & R13 and Channel 4 = R14 & R15. If the unit is to be used for
applications other than switching audio, the Silence Sensor and ACT detection cir-
cuit should be disabled. To disable, remove the following components: R24, R25
and RP9.
CAUTION!
Installation of the SS 4.1
Plus in high RF environ-
ments should be per-
formed with care.
Shielded cable is sug-
gested for all control,
audio inputs and out-
puts. All shields should
be tied to the “GND”
terminal. The station
ground should be con-
nected to the chassis
ground screw (CH1)
located behind J1, as
viewed from the rear.
