SS 8x1 II Installation and Operation Manual

DESCRIPTION

PRODUCT DESCRIPTION

The SS 8.1 II passively switches or routes a variety of electrical signals to a desti-

nation. The SS 8.1 II selects any one of 8 stereo inputs to a single stereo output. The

SS 8.1 II provides PASSIVE switching through gold contact relays. The passive

switching means that the unit can route a signal in either direction. Due to the pas-

sive nature of the switching, any input level and impedance can be used. Inputs may

be balanced or unbalanced, while output levels, impedance, distortion, noise and

balancing will match that of the selected input. In addition to their normal use with

audio signals, the unit can also be used to switch AES/EBU digital signals and tele-

phone lines.

FEATURES

• Operational control by front panel switches with LED indicators, contact closures,

5-volt TTL/CMOS logic levels and/or the multi-drop RS-232 serial port.

• Removable screw terminals (Euro) are provided for audio and remote control con-

nections.

• Audio switching via sealed relays utilizing 2-form-C bifurcated - crossbar silver

alloy with gold overlay contacts.

• Logic functions via microprocessor and non-volatile memory.

• The power-up feature allows the user to select which one source is active at power

up, including the last source selected.

• The “ACT” circuit performs as an audio activity monitor with front panel LED and

open collector status output.

• The “ENABLE” switch provides a safety lock to the front panel source selection

switches.

• The audio “MUTE” switch allows the user to turn off the audio output when acti-

vated.

• The “STEP” function allows the user to single step through each channel or to

automatically sequence with user programmed channel steps and speed.

• Eight remote inputs, user configured for remote control or “PIP” (GPI) functions.

SS 8x1 II Installation and Operation Manual

DESCRIPTION

FRONT PANEL DESCRIPTION

Source Switches:

Each switch represents an input to be routed to the switcher’s output. High quality

tactile switches will give the user years of dependable service. Each switch has an

associated LED indicator, which will illuminate when that particular source is rout-

ed to the output. When a source is selected, the previous source will be deselected,

(interlocked). The front panel is also equipped with a MUTE switch. This switch

turns off the audio output. The ENABLE switch, when enabled, must be pressed

and held in order for any of the other switches to function. This function may be

bypassed.

LEDs:

LED indicators will illuminate when the desired channel is selected. The Pwr/Ser

LED displays valid power and serial data activity. The mute LED denotes when

audio is off. The activity LED is lit when audio is present at the output. Threshold

is set at –40db.

REAR PANEL DESCRIPTION

The rear panel contains the inputs, outputs and remote control interfacing connec-

tors. Audio inputs, outputs and remote control connections are routed through

removable screw terminals (Euro). A RJ-11 modular jack is provided for the multi-

drop serial port.

Power:

Connect the 2.1mm coaxial type power connector into the unit and the power sup-

ply into a 120 Vac 50-60 Hz power source. The front panel Pwr/Ser LED indicates

when power is applied to the unit.

Audio Signal Connector:

The SS 8.1 II is supplied with Pluggable Screw terminals (Euro) and Mating con-

nectors. Channel and polarity designators can be found on the chassis, as viewed

from the rear.

“Remote” Control Connector:

Pluggable Screw terminals (Euro) and mating connectors are provided for connec-

tion to equipment, which will remotely control the SS 8.1 II. Pulsing the “MUTE”

input to ground (low) would turn off the output of the SS 8.1 II until a front panel

source switch is pressed, a remote control input is activated or the unit is powered

up. Pulsing the “STEP” input to ground will step the unit one source for each low

to high transition on this input. Automatic sequence may be accomplished by hold-

ing the step input low for two seconds. The unit will now step to each source at a

user programmable rate from 1 to 999.9 seconds. The number of inputs sequenced

may be programmed for channels 1 to 8. The step input is helpful in freeing up valu-

able remote control channels. This feature may also be used to sequence through

multiple station air monitor signals for program on-hold feed.

SS 8x1 II Installation and Operation Manual

INSTALLATION

INSTALLATION GUIDELINES

It is recommended that all cables connected to the SS 8.1 II 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 8.1 II is simple to install. The signal inputs, outputs are connected via plug-

gable screw terminals. Installation of the SS 8.1 II 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 8.1 II carefully for any damage that may have been sus-

tained during shipping. If any is noted, please notify the shipper immediately and

retain the packaging for inspection by the shipper. The package should contain the

SS 8.1 II, power supply, reversed modular cable, 9-pin “S9” D-Sub adapter and

audio and remote control mating connectors. Manual for this product may be down-

loaded from the Broadcast Tools web site.

STEP 2: SOURCE TERMINATION RESISTOR REMOVAL

Input sources that are not selected are terminated with a 10K Ω. If you do not want

this load applied across the deselected sources, it may be removed from each chan-

nel. Each channel has a pair of resistors.

EXAMPLE: Channel 1, relays K1 A&B switches the signal; R15 & R21 are the

10K Ωload resistors. As delivered, all channels are configured with these resistors

installed. To remove the load resistors from a channel, locate the proper resistors for

that channel, cut its leads and discard the resistors.

STEP 3: BENCH TEST and OPTIONS

Place each unit on a workspace and connect power to the unit. Check to see if LED

#1 (Switch 1) and the Pwr/Ser LED are lit (Source one is the power-up factory

default). Connect an audio source to stereo input one and a monitoring device to the

output. Verify that audio is present. Repeat the process until each channel’s oper-

ation has been verified.

Tool Tip: The “ACT” LED is also an excellent audio output indicator.

CAUTION!

Installation of the SS

8.1 II in high RF envi-

ronments 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.

STEP 4: MOUNTING

Mount the unit on a rack shelf, such as the Broadcast Tools RA-1, allowing adequate

airflow for cooling. The RA-1 is furnished with filler panels to cover open spaces.

STEP 5: CONNECTYOUR EQUIPMENT

The SS 8.1 II interfaces to your equipment (sources and loads) through the rear

panel pluggable screw terminals. Follow the legends for the desired audio input,

output and remote control connections, which appear on the rear side of the chassis.

Remove each screw terminal, strip each conductor and insert the conductor into the

terminal and screw down the capture screw. The terminals accommodate wire sizes

from 16 - 28 AWG solid or stranded wire.

Control:

The front panel functions are brought out through the rear panel “REMOTE” con-

nectors TB 6 & 7, providing a means of controlling the SS 8.1 II from a remote

point. The digital inputs may be connected to any remote pair of switch contacts,

such as external relays, switches, etc. The digital inputs may also be connected to

external open-collector circuits, contact closures or 5-volt TTL/CMOS logic signals.

Status:

The status signals are supplied through the “Remote” control connector as individ-

ual open collectors. The open collectors may be used to provide status to a remote

control point to indicate which source is selected. The status output for the selected

output will go low (user programmable function), providing a return for an LED

indicator, TTL/CMOS logic or relay. External pull-up resistors may be required in

some installations.
