The RU-SM16D has four separate inputs. Each input may be individually calibrated for unbalanced consumer, balanced professional, 8 Ohm speaker line or constant voltage speaker lines (25 V, 70 V or 100 V). All connections are made using detachable terminal blocks.

Key Features

Precision Audio Level Metering
Digital 16 LED String Display Indication
Four Mono Meters or Dual Stereo Metering
Line-Level, Speaker-Level or 25/70/100 V Audio Input
Selectable Fixed or Variable Calibration
Individual Channel Calibration Controls
Selectable Peak or Average Metering
Peak-Hold Display for +10, +14, +18 dB

The RU-SM16D uses bright LEDs for good visibility. Each input has a label area for identification of the source or function being metered.

4 x 1 STEREO AUDIO SWITCHING IN A CLASSROOM

Remote Source Selection and Volume Control

The classroom is equipped with three A/V sources (Computer, DVD and VCR) and an audio-only input on a wall plate. Staff selects the audio source and sets the level through the RDL RU-ASX4DR Remote Controlled Audio Selector using a D-RC4M Four Channel Remote Control and a D-RLC10M Remote Level Control. All video signals are run directly to the projector which provides video source selection. Sources may be muted by simply de-selecting the active input at the D-RC4M or by operating the MUTE switch on the D-RLC10M. The D-CIJ3D Consumer Input Jack Panel is used to balance the stereo signal of an MP3 player or any consumer source and to provide galvanic isolation.

Add a Versatile, High-Quality Audio Attenuator to Any Sound System: RDL RU-VCA2A

If you’re in search of a versatile and high-quality audio attenuator to enhance your sound control capabilities, consider exploring the RU-VCA2A Digitally Controlled Attenuators by RDL. These attenuators are designed to manage mono or stereo, balanced or unbalanced line-level signals with exceptional precision. They feature noiseless digital attenuators that offer precise and dependable level adjustments in 0.5 dB increments, delivering outstanding low-noise performance for even the most demanding applications.

Level control can be easily executed either internally through the front-panel pushbuttons or remotely using single or multiple control units. These remote control units offer various options, such as pushbuttons, momentary pulses (rotary encoder), or voltage control ranging from 0 to 10 Vdc, or a 10 kΩ Potentiometer.

For added convenience, you can establish a custom preset level and swiftly recall it by simply pressing the front-panel GO TO PRESET button. Among the wide array of remote control options available for this unit, the D-RLC2 Remote Level Control stands out as a popular choice. This remote is equipped with two momentary pushbuttons, UP and DOWN, and a 10-segment LED visual level display. Pressing these buttons sends the corresponding signals to the RU-VCA2A, and simultaneously pushing both buttons restores the level to the PRESET setting.

Additionally, you have the flexibility to configure this module to power up at either the preset level or the last used level setting. Installation and operation of the RU-VCA2A are straightforward, making it compatible with various RDL remote controls or OEM equipment. Whether you require precise level adjustments for microphones, instruments, line sources, or speakers, the RU-VCA2A offers a seamless and accurate solution. Elevate your audio control capabilities with ease by incorporating the RU-VCA2A into your setup.
