The RDL Ru-MLD4 1x4 Mic/Line Distribution Amplifier is a versatile and reliable solution for amplifying and distributing microphone or line-level signals in various applications, such as audio installations, conference systems, and broadcast studios.
This compact, rack-mountable device features four independent input channels, each capable of accepting either mic or line-level signals. The inputs are transformer-isolated, ensuring the highest level of signal integrity and protection against common-mode noise.
The Ru-MLD4 amplifies each input signal with adjustable gain control, allowing for precise level matching between sources and ensuring optimal performance. The amplified signals are then distributed to four separate output channels, which are transformer-isolated and can be configured as mic or line outputs, depending on the application requirements.
The amplifier's output levels are continuously adjustable, with a range of 12dB, enabling fine-tuning of the output levels to meet the specific needs of various microphones or speakers. The output impedance can also be set to either 600 ohms or 150 ohms, making it suitable for a wide range of load types.
The Ru-MLD4 is designed with ease of use in mind. It features front-panel metering for all four input and output channels, allowing for quick and easy level monitoring. The amplifier also includes a power sequencing feature, which ensures that the outputs are turned on after the inputs have received power, preventing potential damage to sensitive equipment.
The RDL Ru-MLD4 is built to the highest standards of quality and reliability. It features rugged, steel construction and is designed to operate in a wide range of temperatures and humidity levels. The amplifier also comes with a 5-year warranty, ensuring peace of mind for customers.
In summary, the RDL Ru-MLD4 1x4 Mic/Line Distribution Amplifier is a versatile and reliable solution for amplifying and distributing microphone or line-level signals. Its transformer-isolated inputs and outputs, adjustable gain control, and rugged construction make it an ideal choice for a wide range of applications. With its easy-to-use front-panel metering and power sequencing features, the Ru-MLD4 is a must-have component for any professional audio installation.
