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).

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.

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.

Description:

In an amusement park’s Haunted Mansion ride, pre-recorded screams on the FP-MR2 Message Repeater are triggered by a motion sensor’s contact closure in real time when the “victims” enter a particular room. The eerie background music is ducked when the message is played and restored after completion. The FP-MR2 is fed into an RU-PA40D Power Amplifier. The amplifier feeds two loudspeakers. Volume is adjusted by an RLC10KS Level Control.

Description:

Each piece of exercise equipment is outfitted with an RDL SAS-HC8 Headphone Control Station so that users can select from eight audio programs and adjust volume to their own preference. Six audio sources in this system are associated with video monitors at the front of the room. A TX-J2 Unbalanced Input Transformer is used to combine each stereo signal to mono. Two other channels are from radio or satellite receivers. The SAS-8i Audio Input Chassis also provides an “all call” paging input. The SAS-8i supports four SourceFlex listening stations and multiple SourceFlex expansion chassis. Listening station expansion may be added in groups of two with the SAS-82 2 Station Audio Controller or in groups of eight with the SAS-8C 8 Station Audio Controller. There is no practical limit to the number of listening stations in any system. Connections between the controller and each listening station use a multi-conductor twisted-pair cable. The SourceFlex system is reliable and cost effective without the problems of wireless systems with rechargeable batteries.

Description:

Speeches, government meetings, product announcements and other media events covered by reporters require multiple high quality audio feeds in the press room. The recording equipment may require a balanced or unbalanced line level or mic-level signal. Each output feed must be isolated so that if one output is accidentally shorted or back-fed, all other feeds and the public address system remain unaffected. An RDL RU-ADA4D Audio Distribution Amplifier provides isolated audio output signals that drive a variety of audio jacks on a “Media Panel.” An RDL RU-MX4 Professional 4-Input Mixer with selectable compressor is used to mix the audio sources. The line-level mix is distributed by the RU-ADA4D to up to 8 line-level outputs on RCA, 1/4″ phone, or XLR jacks. Three of its outputs are padded down to mic level using RDL TX-LM2 line-level to microphone-level transformers. All jacks shown are on Decora® compatible wall plates. These jacks are also available in the RDL AMS series should a custom rack or tabletop configuration be preferred. Video distribution may be added using RDL composite and VGA/XGA distribution amplifiers.

This example shows the use of the RDL EZ-MCP1 Microphone Compressor and the RDL HD-PA35U Power Amplifier in a Karaoke system. The EZ-MCP1 is an in-line device that connects between a dynamic or condenser microphone and the mic-level input of the Karaoke machine. When properly adjusted, it will produce consistent audio levels despite wide variations of up to 30 dB from the microphone and will control signal overloads that cause distortion and clipping. The output of the HD-PA35U Power Amplifier is rated at 35 W RMS into a 4Ω or 8 Ω load. The included analog compressor/limiter allows the amplifier to produce audio output levels and clarity normally expected from amplifiers with a much higher output rating. Additionally, the amplifier includes Sleep Mode circuitry that puts the amplifier into standby mode after a predetermined period of time with no audio at the input. The presence of signal at the input causes the HD-PA35U to return to full operation.

Description:

An RDL TX-J2 Unbalanced Input Transformer provides a balanced mono audio source from the computer in this information kiosk. The FP-PA18H 18-Watt Mono High Temperature Audio Amplifier provides ample power to drive the 8 Ohm speaker. Its integral compressor/limiter provides consistent levels for enhanced intelligibility without clipping. The ST-PA18H is rated for operation between 0 and 70 degrees C (158 degrees F) so that it can operate comfortably when used in a space that is not temperature controlled.

Description:

RDL’s Twisted Pair Connector Plates and Remote-Controlled Mixer is ideal for this hockey rink or other sports arenas announcement system. The straightforward design makes the system easy to understand and operate for the timekeeper. RDL D-TPS1A and D-TPS7A input plates located inside the timekeeper’s box send a local microphone and a line level audio source (Computer, MP3, CD or DVD player) to the first two channels of the FP-TPX3A Remote Controlled Mixer in the amplifier rack. The third mixer channel is fed from another D-TPS1A located near the ice, providing a microphone input close to the action. Installing the D-RC3M Remote Mixing Control within arm’s reach allows the timekeeper to easily adjust levels and mute any of the sources. The FP-TPX3A incorporates an audio detector and timer that can be used to turn off the power amplifiers when the system is not being used, resulting in substantial energy savings. The mixer inputs and the remote control are all connected using common UTP cable such as CAT5 with standard RJ45 connectors.

Description:

A video source distributed to remote viewing areas such as public transport waiting areas or overflow meeting rooms is easily degraded by “ground loops”. The difference in ground voltage between the video source and monitoring locations can create herringbone patterns or rolling hum bars. Small “ground loop” voltages can easily impair the quality of a 1 Volt video signal. The RDL EZ-HK2 at the monitor location removes the “ground loop” using a high-quality video transformer in a shielded metal enclosure. The input jack is ground isolated. A ground-lift switch allows the output jack shield to be lifted from the metal chassis if required.

Description:

Attendees select the audio source and listening level in their seating box using a wall-mounted SAS-RC8 Room Control Station. Three sources are available for selection in each seating box: Stadium Broadcast Audio, MP3 music or the Press Feed. The SourceFlex system accommodates a maximum of 8 possible sources, plus one paging input. Mono sources are connected to the rack-mounted SAS-8i Audio Input Chassis. Stereo sources are converted to mono using RDL TX-J2 modules. All control, power and audio signals connect through a single wiring cable between each SAS-RC8 and the SAS-8i. A line-level output from each wall control is amplified by an FP-PA20A 20-Watt Power Amplifier to two or more 70 V loudspeakers. An internal amplifier in the SAS-RC8 may be used to drive 8 Ohm speakers in seating requiring up to 1.5 Watts. The SAS-8i supports a maximum of four separate seating box zones and provides connection of multiple expansion chassis: SAS-82 Two Station Controllers and SAS-8C Eight Station Controllers. There is no practical limit to the number of possible zones. SourceFlex wall controls are available in several styles to match any decor.

Description:

This application provides multiple paging locations, with priority assigned to each location. Each location has a mic equipped with a PTT (push-to-talk) momentary pushbutton. The STM-2 preamp for each microphone should be installed near the associated mic. Wiring between each STM-2 output and the corresponding ST-VP2 is balanced, connected with shielded or unshielded twisted-pair cable. When any microphone is used, the music fades down and paging becomes active. The highest priority mic overrides the lower priority mic(s). This arrangement may be carried out for an unlimited number of paging locations. The FP-PA20A 20-Watt Power Amplifier feeding 70 Volt speakers is used in this example. RDL offers a wide range of power amplifiers for paging and public address applications.

Description:

One of the common uses for the ST-ACR2 Audio Controlled Relay is to provide switching when a priority audio source is active. In this example the priority source is the jukebox which shares the same audio system as the background music source. The ST-ACR2 samples line level audio from the jukebox and switches the audio input to the power amplifier from the jukebox when it senses audio from the jukebox. The RDL TX-PA40D 40 W Stereo Audio Power Amplifier is shown in this system.
