RDL manufacturers dozens of audio amplifiers for Dante network or conventional audio systems, including a selection of plenum-rated network audio amplifiers. Amplifier models and features: SF-NP35E PoE++ Network to 35 W Mono Audio Amplifier – 70 V or 100 V SF-NP16E PoE+ Network to 16 W Mono Audio Amplifier – 70 V or 100 V […]
The AMS-TS1 Illuminated Touch-Activated Pushbutton is a versatile interface used to initiate functions such as MUTE or OVERRIDE in automatic mixers and digital audio signal processors. It can be integrated with virtually anything that can be controlled by an Open Collector (pull to ground). Integral red and green LED’s indicate the status of the pushbutton. […]
A common application we are asked to help with is a simple Two Room Combining System. The system shown in the drawings below allows the user to combine the outputs of the ROOM A and ROOM B mixers and route the combined signals to the ROOM A and ROOM B amplifiers. The D-RT2 Remote Control […]
In order for Dante devices to communicate with a computer loaded with DANTE CONTROLLER, the Dante devices and the computer must first be on the same network (in the same range of IP addresses). If not on the same network, Dante Controller will discover and display the names of the devices, but will not be […]
The D SERIES-TPSM2A is a single-gang Decora style two channel microphone preamplifier compatible with other RDL Format-A senders and receivers as well as RDL RU-FN and RU-BNF Dante™ interfaces. The D-TPSM2A provides 48 volt phantom power for condenser microphones and XLR inputs accept signals from both dynamic and condenser microphones. One of the features that […]
The RU-MLB series of Dante bidirectional interfaces provide independently switch-selectable mic or line inputs and line-level outputs. They are available in 2 and 4 channel versions with or without PoE. When an input is set to receive microphone signals, the module provides P48 phantom for operation of balanced condenser microphones. When a condenser microphone is […]
Some time ago we discussed the various uses of RDL ST-ACR Series Audio Controlled Relays. One of the applications mentioned was Jukebox Overrides Background Music . We are frequently asked to provide point to point wiring diagrams for this type of application and have produced the following drawings for balanced or unbalanced / mono or […]
RDL FORMAT-A products offer a variety of solutions to simplify the design and installation of any sound system by using economical and readily available CAT5 or better 4 PR UTP cabling. FORMAT-A products are capable of transporting up to three channels of audio over a single four pair cable to single or multiple endpoints. Three […]
A recent call into the RDL Tech Support line came from a contractor who was installing a paging system on a campus where it was not practical to run cable between the various buildings. They had installed a low power FM transmitter at the main office and receivers that fed the amplifiers in the various […]
The high performance ST-GCA3 is an automatic gain control amplifier that provides a constant average audio output despite variations in input levels. It is used extensively in broadcast production and transmission, conferencing and sound reinforcement systems. The ST-GCA3 automatically provides gain to low level signals and attenuation to high levels. The adjustment rate […]
Proper power ON and OFF sequencing in a sound system will prevent annoying and sometimes damaging THUMPS and POPS by turning power amplifiers ON last and OFF first. Sequentially powering ON multiple electrical / electronic components will also help manage high inrush currents that can cause circuit breakers to trip and current-limited power supplies to […]
The ST-IC1 Intercom Amplifier is the building block for a variety of voice intercom applications ranging from Patient Monitoring
