If you have ever had more than one transceiver, amplifier, or antenna, and you needed the capability of using one of three radios with any one of 3 amplifiers with up to four antennas, you had to unplug coaxes, unplug ALC lines, unplug the speaker cables, etc., and then reconnect them all to accommodate the new radio and antenna that you need to use. Sometimes, this also involved using multiple coax switches and then praying that you hooked it all up correctly... What a pain! NEVER AGAIN...
NOW THERE IS A FASTER, SAFER, AND EASIER WAY!
If you’re tired of all of the cable swapping, then the 3 X 4 SWITCH PLUS was designed just for you! No more plugging and unplugging cables to connect your antennas, amplifiers, radios, and speakers.
Once you connect your coax cables from the 3 X 4 SWITCH PLUS to your existing radios (up to 3), to your amplifiers (up to 3), and to your antennas (up to 4) you’re done.
Imagine simply turning a single knob to select your transceiver and antenna, while at the same time, having the ALC and speaker connections all ready to go. Connect it all up once and then forget it. Now that’s too easy!!
If you want to use different radios (up to 3) to any one of up to three amplifiers connecting to one antenna, or want to use one radio to different amplifiers to different antennas (up to 4), or just about any combination of radios, amplifiers, and antennas, the 3 X 4 SWITCH Plus will do the job!
The 3 X 4 SWITCH Plus supports up to 1500 watts and has greater than -70dB of switching isolation.
The 3 X 4 SWITCH Plus is built with a rugged steel chassis and very easy-to-use front-panel controls with clearly marked rear-panel connections.
The 3 X 4 SWITCH Plus may be connected to the iPlus to select the radio to be used.
The 3 X 4 SWITCH Plus has all of the necessary connectors to control the routing of radio, amplifier, antenna, speaker, and ALC lines. The 3 X 4 Switch Plus makes your operation easier and quicker!
But there’s even more… Connect it with your existing iPlus, and/or use two 3 X 1 unit and/or two 1 X 4 units for even more complex switching possibilities!
The bottom line is this; You are in total control!!
3 X 1 Front Panel Controls
POWER SWITCH AND POWER ON INDICATOR
This switch disables all three rear output Amp Keying RCA connectors. The Red LED will illuminate whenever the output amplifier Keying RCA connectors are disabled.
LOCAL / REMOTE INPUT SELECT SWITCH AND LED’S
This 4 position rotary switch is used to connect one of up to three radios from the Input A, B, C connectors to the coax, ALC, amp keying and speaker output connectors. When this switch is turned to select “A” the radio that is connected into RF input A will be connected to the 3 X 1 output. When this switch is turned to Remote, Input A, B, or C is selected by the remote device connected into the rear 5 PIN DIN INPUT Select connector or Input Select RCA connectors. The appropriate A, B, or C input is sent to the 3 X 1 Output and the corresponding green LED will illuminate.
RF OUTPUT SWITCHES
These switches direct coax inputs A, B, and C to the output of the 3 X 1 Controller / Switch. When a 1 X 4 Antenna Switch is connected to the coax output of the 3 X 1 Controller / Switch, these switches control the 1 X 4 Antenna Switch which is connected to one of 4 outputs based on these switch positions.
When the AUX switch is turned on, the coax input of the 1 X 4 Antenna Switch is connected to the AUX coax output of the switch. The AUX green LED on the 3 X 1 Controller will illuminate when the AUX switch is on.
3 X 1 Rear Panel Connectors
RCA INPUT SELECTS
These RCA connectors are used to remotely replace the function of the Local / Remote Select Switch. These RCA connectors are active when the Local / Remote Input Select Switch is in the Remote position. The internal circuitry in the controller only allows a single coax input to be connected to the coax output, even when multiple RCA Input Selects are grounded.
These RCA inputs accept mono or stereo inputs from up to 3 radios or other sources. The 3 X 4 Controller will send one of the three speakers (RCA stereo) inputs to the speaker (RCA Stereo) output. The RCA speaker output may be connected to a single mono or stereo speaker system or recording device.
Station ground should be connected here.
COAX RF INPUTS
These three coax inputs are used to connect RF devices such as transceivers or RF linear amplifiers to the 3 X 1 Controller / Switch. The front panel mounted Local / Remote Input Switch is used to select which one of the three RF inputs is connected to the 3 X 1 RF Output.
3 X 1 COAX RF OUTPUT
This coax output is connected to one of three coax inputs. Which input is connected to the output is determined by the position of the front panel mounted Local / Remote Input Switch.
This 6 pin DIN Connector is used to provide DC power to the unit. Power requirements are 10 to 15 VDC at 1 AMP for Powering one Controller and one 1 X 4 Antenna Switch. The power required for two Controllers and two 1 X 4 Antenna switches is 10 to 15VDC at 2 AMPs.
This 6 pin DIN connector is used to provide DC power to another 3 X 1 Controller/switcher and 1 X 4 Switch. To provide power for a second Controller and second 1 X 4 Switch a cable must be connected from the Power Out of the 3 X 1 controller providing power to the Power In of the controller requiring power.
DIN INPUT SELECTS
This 5 Pin DIN is used when the Local / Remote Input Select Switch is in the remote position. It allows the selection of the A, B, C coax inputs to be selected remotely. When the Local / Remote Input Select Switch is in the Remote position this 5 PIN DIN is active.
OUT TO 1 X 4 SELECT
This 5 Pin DIN is connected to the 1 X 4 Switch 5 pin DIN. This connection switches the coax input of the 1 X 4 Switch, to one of the 4 coax outputs.
This 5 Pin DIN is used to identify which of the 3 coax outputs (1, 2, or 3) on the 1 X 4 Switch is active. This DIN output can be connected to Input Select of a second switch when adding an additional level of switching is required.
1 X 4 CONNECTIONS
Station ground should be connected to this connector. Grounding this point grounds any of the four coax connectors that are not connected to the Input coax connector.
This unit is capable of handling up to 1500 watts PEP of RF. These 4 coax RF connectors are used to connect antennas or other external devices to the Input Coax RF Connector. Switching the input connector to one of the 4 Output connectors is done using the control 5 Pin DIN connection.
This 5 Pin DIN switches the coax input of the 1 X 4 Switch to one of the 4 coax outputs. The 1 X 4 Antenna Switch Control Connector may be connected to the 3 X 1 Controller / Switch 1 X4 Select 5 pin DIN output. Below is a picture that defines the function of the pins on the 5 PIN DIN.
OUTPUT COAX LEDs
These LEDs are wired to indicate which coax output is connected to the coax input.
