RDL RU-SM16D overview

  • 1Description

The RDL RU-SM16D 4-Channel Audio Meter is a 1RU 1/3 rack module designed for precise metering of up to 4 channels of audio. The unit can be used for either 4 channels of mono metering or dual-stereo operation and is designed to be integrated into new and existing setups.

Each channel utilizes sixteen LED indicator lights and may be individually calibrated for unbalanced consumer, balanced professional, 8 Ω speaker line, or constant voltage speaker lines (25V, 70V, 100V). The rear panel features terminal blocks for connections and variable or fixed calibration for 25V, 70V, 100V, and +4 dBu sources. When placed in the "variable" position, a set of front panel multi-turn trimmers can be used for calibrating the meter levels.

Each meter on the unit can be set to either peak or average audio level displays. In monaural applications, a mono source can be fed to two meters for both peak and average metering. In stereo mode, both the left and right channels can be sent to one peak and one average metering channel.

    RDL RU-SM16D reviews

    RU-SM16D 4-Channel Audio Meter is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from The BEST VU meter period This meter is the very best most accurate VU meter I have ever used. It is pre calibrated and requires no adjustment!!! Simply put, I have every VU Meter made and none work as well as this one. It is expensive but worth every penny. It is very well build and compact. My only complaint is really a wish, I would like to have 1/4 TRS connections, however the phoenix connections work fine as well.
