POWER 3 ACTIVE SPEAKERS ON FORMAT-A CABLE RUN

Power Inserter / Signal Breakout Module Permits Home Run Cabling From a Dante™ Network

AN-2234

Description:

Each Format-A active loudspeaker requires 100 mA of supply current. A TX-TP4PW Power Inserter / Signal Breakout module provides up to 200 mA to each D-PSP1A active loudspeaker. The TX-TP4PW Power Inserter / Signal Breakout module is used to receive Pairs A, B and C from a single cable run connected to the RJ45 output of the RU-BNF Format-A Bi-Directional Network Interface. The RU-BNF converts 3 Dante sources to Format-A. Those sources on pairs A, B and C are all passed through to each home run cable that connects to the RJ45 input of each D-PSP1A Format-A loudspeaker. A rear-panel switch set during installation selects which of the three audio sources is amplified by the powered speaker. All D-PSP1A loudspeakers may be set to the same pair if desired. All the Format-A modules are powered by the external supply connected to the TX-TP4PW. This setup can be replicated for the remaining two Format-A outputs from the RU-BNF. Additionally, the Format-A input on the RU-BNF may be used to convert three Format-A sources onto the Dante network (not shown).

PROVIDE POWER TO THREE FORMAT-A LOUDSPEAKERS

Connect Multiple Powered Speakers to a Single Format-A Cable Run

AN-2235

Description:

Three Format-A powered speakers require more power than is available from a single Format-A sender jack. And its available power is further reduced by the distance of the cable run. This installation provides a TX-TP4PW Power Inserter at a suitable cable distance from the three listening locations. All three Format-A sources on pairs A, B and C pass through the TX-TP4PW and are available at each powered speaker. A recessed rear-panel switch is set by the installer on each D-PSP1A to select which pair is amplified. The three loudspeakers may be set to amplify the same pair if desired, or each may amplify a different pair. All the Format-A modules are powered by the external supply connected to the TX-TP4PW.

SIMPLE MIC SWITCH FOR ANNOUNCE BOOTH TALENT

Push-to-Talk and ON AIR Indicator Controlled by a Single Pushbutton

AN-2188

Description:

The talent can easily and silently switch the microphone on or off in the announce booth. The ST-LCR2 Alternate Action Relay is triggered by a Momentary Pushbutton Control Switch to turn the microphone on and to control the visual indicator. A single push of the button latches the ST-LCR2 relay ON and a second push turns it OFF. One set of the dry relay contacts is used to turn the “ON AIR” sign ON/OFF while the second set may be used to control other indicators or functions. The SLAVE output of the ST-LCR2 is connected to the CTRL input of the STM-2X to activate the preamplifier output. Note that an STM-2X output may be connected to either the mic or line input of the studio mixer.
