PRODUCT DESCRIPTION

The 16x2, sixteen input, dual output stereo switcher/router passively switches or routes any one of 16 stereo inputs to either or both stereo outputs 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 16x2 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 2 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 either or both audio outputs when activated.

The Enable switch provides a safety lock to the front panel source selection switches. Dual Audio Activity Monitor LED’s with remote status monitor the output audio from either or both outputs. A Serial Port allows communication and operation from a host computer’s serial port. 16 “PIP” TTL/CMOS compatible inputs and open collector GPI ports allows the serial port monitoring of contact closures from satellite receivers; tone decoders; etc; while the open collectors provide a means of controlling devices with commands from a host computer’s serial port. Source number one is configured by default to route audio to both outputs in the case of loss of power to the unit. Non-selected sources are terminated with 100K

Ω

, load resistors.

APPLICATIONS

Some of the applications of the 16 x 2 include: Studio selection and routing; Audio processing selection; Exciter input selection; Remote broadcast input selection; STL source selection; Automation source selection; 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 either or both of the outputs. 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 either or both of the outputs. 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 OP 2 and/or ENABLE switch, turns off the output.

LEDS

LED indicators, which will illuminate when the desired channel is selected to output one, slowly flash when to only output two and rapidly flash when to assigned to both outputs. The Pwr/Ser LED displays valid power and serial data activity. The mute LED denotes when audio is off. The respective activity LED’s light when audio is present at the appropriate output.

REAR PANEL DESCRIPTION

The rear panel contains all input, output 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 2 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

The male 37 pin “D” connector is provided for connection to equipment, which will remotely control the 16 x 2. Momentary contact closure to ground or active low logic will satisfy all input functions.

INSTALLATION

Installation of the 16 x 2 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 2 as viewed from the rear. It is recommended that all cables connected to the 16 x 2 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 2 is simple to install. The signal inputs, outputs are connected via pluggable screw terminals. Installation of the 16 x 2 consists of six 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 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 2 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 2, 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 100K

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.


• 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.

NOTE:

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(s). Verify that audio is present at both outputs. Repeat the process until each channel’s operation has been verified.

OPTIONS

JP2 To enable the front panel “

ENABLE

” switch, place a jumper over JP2. The

Enable

switch is disabled at the factory.

When the unit is in

“Programming” mode, the “Channel 16” and

“Power” LED’s flash rapidly. The current settings are displayed on their respective

LED’s.

Serial Burst Mode Commands

The unit is controlled via the Burst mode. The baud rates are selected on page 6.

The 16 x 2 may be serially controlled via the multi-drop RS-232 port. Commands may be entered with a short form code (burst mode). All commands and responses use normal ASCII characters, facilitating scripting. A burst mode command starts with an asterisk (“*”) followed by the device (ID) address as a single decimal digit.

The device (ID) address (0-3) is specified on the on-board DIP switches. A burst mode command must be entered within 5 seconds, or it will time out. No carriagereturn or line-feed is required to terminate the command except for those few commands of variable length, if the maximum length is not sent. If the command requests a response, the response will consist of an upper case “S”, followed by the unit address, and then the specific response. If acknowledgements are enabled, successful commands are responded to with “RRR”, while errors get an “EEE” response. The syntax of each command is given below. The syntax shows the command exactly as it should be sent,

except that lower case characters represent values that should be substituted.
