SS 16.1 Installation and Operation Manual
PRODUCT DESCRIPTION
The 16x1 passively switches or routes any one of 16 stereo inputs to one stereo output or vise-versa through gold contact relays. The passive nature of the switching allows for any input level and impedance to 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 16x1 can also be used to switch digital signals and telephone lines. Control is via front panel switches, contact closures, open collector status and/or multi-drop RS-
232 port. Removable screw terminals are provided for all audio connections.
The 16 x 1 has several unique features. The Power-Up feature allows the user to select which of any source is active at power up, including the last source selected.
Audio mute allows the user to turn off the audio output when activated. The Enable switch provides a safety lock to the front panel source selection switches. An Audio
Activity Monitor LED with remote status. A Step Input provides a means of stepping through each source, including MOH Station Selection. A Serial Port allows communication and operation from a computer’s serial port. A 2 x 1 bypass output switcher is provided to allow switching between the 16 x 1 and an external source.
Source number one is configured by default to route audio to the output in the case of loss of power to the unit. Non-selected sources are terminated with 10K
Ω, load resistors.
APPLICATIONS
Some of the applications of the 16 x 1 include: Studio selection and routing; Audio processing selection; Exciter input selection; Remote broadcast input selection; STL source selection; Automation source selection; Multiple station Music On-Hold and/or PA switching; EAS audio switching; ISDN or Phone hybrid feed selection;
IFB selection; Satellite audio channel switching and console monitor inputs and outputs selection.

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 routed to the output. When a source is selected, the previous source will be deselected,
(interlocked). The ENABLE switch, when enabled, must be pressed and held in order for any of the source switches to function. This function may be bypassed.
The front panel is also equipped with a MUTE switch. This switch, when pressed in combination with the ENABLE switch, turns off the output.

SS 16.1 Installation and Operation Manual
FRONT PANEL DESCRIPTION
LEDs:
LED indicators, which 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.
REAR PANEL DESCRIPTION
The rear panel contains all the inputs, outputs and remote control interfacing connectors. Audio inputs and outputs are routed through pluggable screw terminals.
Remote control is accomplished via a 37 pin “D” connector. A modular jack is provided for the multi-drop serial port.
Power:
Connect the 2.1mm coaxial type power connector into the unit and the 9 VAC @ 500 ma wall transformer into a 120 Vac 50-60 Hz power source. The front panel power
LED indicates when power is applied to the unit. (220 Vac 50-60 Hz wall transformer OPTIONAL)
Audio Signal Connector:
The 16 x 1 is supplied with Pluggable Screw terminals (Euro) and Mating connectors.
Channel and polarity designators can be found on the left side of the printed circuit board, as viewed from the rear.
“Remote” J3, Connector:
A male 37 pin “D” connector is provided for connection to equipment which will remotely control the 16 x 1. Pulsing the “MUTE” input to ground (low) will turn off the output of the 16 x 1 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 holding the step input low for two seconds. The unit will now step to each source at a menu programmable for 1 to 999 seconds. The number of inputs sequenced may be programmed for channel 1 to 16. The step input is helpful in freeing up valuable remote control channels. This feature may also be used to sequence through multiple station air monitor signals for the music on-hold feed.

SS 16.1 Installation and Operation Manual
INSTALLATION GUIDELINES
Installation of the 16 x 1 in high RF environments should be performed with care.
Shielded cable is suggested for all control, audio inputs and outputs. All shields should be tied to the EGND terminals. The station ground should be connected to the chassis ground screw located on the far right side of the 16 x 1 as viewed from the rear. It is recommended that all cables connected to the 16 x 1 be looped through ferrite cores to suppress RF. Surge protection with RF filtering such as the Tripp
Lite “ISOBAR 4 or 6” is also suggested for the wall transformer. The purchase of an inexpensive UPS will provide back-up in case of power outages.
The 16 x 1 is simple to install. The signal inputs, outputs are connected via pluggable screw terminals. Installation of the 16 x 1 consists of six steps:
1. Inspection
2.
3.
4.
Removal of the source termination resistors, if applicable
Bench test and option set-up
Mount the unit in a rack or desktop
5. Connect your equipment to the unit
6. Label the front panel switches
7.
Serial operation, if applicable
STEP 1: INSPECTION
Please examine your 16 x 1 carefully for any damage that may have been sustained during shipping. If any is noted, please notify the shipper immediately. Retain the packaging for inspection by the shipper. The package should contain the 16 x 1, this manual, 37 pin female D-connector/shell, 7 foot modular cable, 9 VAC @ 500 ma transformer, modular cable, 9-pin D-Sub adapter and audio mating connectors.
WEBSITE:
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 channel. Each channel has a pair of resistors.
The Broadcast Tools web site contains ...
• EXAMPLE:
Channel 1, relays K1 A&B switches the signal; R15 & R21 are the load resistors. As delivered, all channels are configured with these resistors installed. To remove the load resistors from a channel, locate via the schematic the proper resistors for that channel, cut its leads and discard the resistors.

SS 16.1 Installation and Operation Manual
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 operation has been verified.
• OPTIONS:
JP13 Selects the logic level for the bypass relay, when bypass is active (factory default). If JP3 is set to LOW, a logic low is required to turn bypass OFF.
If JP3 is set to HIGH, a logic low is required to turn bypass ON.
JP2 To enable the front panel “ENABLE” switch, place a jumper over JP2
Input selection at power-up may be determined by holding down the desired channel push button until all LEDs flash. Factory power-up default is source # 1. The
Enable switch is disabled at the factory.
