PreSonus Universal Control 1.7 Expands VSL’s Smaart Analysis Capabilities

November 13, 2012


The Smaart Room Analysis (SRA) Wizard.
On November 19, PreSonus® will release version 1.7 of its Universal Control software. This free update to the company’s control-panel software features a significant expansion of the Rational Acoustics Smaart Measurement Technology™ that is integrated into the Virtual StudioLive™ section of Universal Control. The update will be available for download from

In Universal Control 1.6, PreSonus added Smaart Measurement Technology’s Spectra module to its Virtual StudioLive control/editor/librarian software for all StudioLive mixers, which is part of Universal Control. This version gave StudioLive owners access to an RTA and Spectrograph.

With Universal Control 1.7, StudioLive 24.4.2 and 16.4.2 users gain the abilities to easily view the frequency response of a venue, quickly calculate and set delay-system timing, and verify output connectivity. (Note that these additional capabilities are not available for the StudioLive 16.0.2 due to its different architecture.)

To accomplish this, PreSonus has added three Smaart system-check wizards to VSL. To use these tools, you need to connect a measurement microphone to the StudioLive mixer’s Talkback input. A high-end mic is not required; most measurement mics can do the job.

The Smaart Room Analysis Wizard

The Smaart Room Analysis (SRA) Wizard is an automated process that guides you through the steps of acquiring a frequency-response trace and then overlays the resulting trace on the VSL display for a StudioLive 24.4.2 or StudioLive 16.4.2 Fat Channel parametric EQ. (A frequency-response trace is the plotted result—frequency and amplitude—of the system measurement.) You can then adjust the parametric EQ to get rid of unwanted anomalies in the room.

The SRA Wizard can do a basic analysis, which requires a single-point measurement, or an advanced analysis employing three separate mic position measurements and averaging them together.

The Smaart System Delay (SSD) Wizard.

The Smaart System Delay Wizard

The Smaart System Delay (SSD) Wizard calculates and sets the correct amount of delay time between two full-range speaker systems, using the StudioLive’s subgroup-output delays. This helps you to synchronize the outputs of secondary (generally, side and rear) speaker systems with the output of the main front speakers in a front-of-house P.A. system. You can synchronize multiple secondary systems using this tool and the StudioLive 24.4.2/16.4.2 mixer’s four subgroup outputs.

The Smaart System Output Check Wizard

The Smaart Output Check (SOC) Wizard verifies that your system outputs are routed correctly and are passing signal. By momentarily taking over the routing and volume control of an output and patching pink noise to it, this tool lets you quickly discover which speaker is connected where and helps you quickly get to the root of a routing problem.
