Use the and keys to zoom the plot vertically. The bottom pane can show multiple metrics at once. The top history pane shows the entire log duration for the currently selected metric, visible in the upper right-hand corner of the pane. It turns red, and the SPL History plots begin to fill with data. Click the Start Logging button to get things rolling. Smaart SPL Getting Started ħ Now we re ready to start logging. You may now calibrate another input if desired or click OK to close the Amplitude Calibration dialog. Once the calibration process completes, enter the level being produced by your calibrator into the Set this value to: field. (For example, if your calibrator is producing 110 db SPL and you want to be able to meter levels up to 130 db SPL, adjust the preamp level until the meter shows a level of -20 dbfs RMS or lower.) Make sure to leave enough headroom so the input will not clip during the show! Click the Calibrate button. Set the preamp gain to give the desired amount of headroom on the meter. (Do this slowly so the pressure change doesn t damage the mic). Turn on the calibrator and fit it over the microphone, ensuring a snug fit. Select the input, then click the Calibrate button to open the Amplitude Calibration dialog. To measure SPL, an input must be calibrated. This will help reduce confusion if more inputs are added later. We ve chosen Channel 1, and given it a Friendly Name of FOH Mic. Check the Use box in the lower pane for each input you want you use. The device must be connected and powered on before Smaart SPL is launched in order to be recognized by the application. Check the Use box for the device you want to use. You can also open it by clicking the Input Config button. Clicking OK brings up the Input Config dialog. If you re launching Smaart SPL for the first time, the program will display a message stating that no calibrated inputs were detected. For an overview of the basics of SPL measurement, see What Is SPL? on page 7. 18Ĥ Getting Started with Smaart SPL This guide will run you through the process of getting Smaart SPL set up to monitor and log sound pressure levels (SPL).

The crew of Davide Lombardi at FOH, Tom Howat at mons and Adam King in production are such a pleasure to work with - all at top of their game. Why would I want to make life difficult by changing that?”īrit Row’s Dave Compton concludes: “Britannia Row Productions are very proud to have such an iconic artist as Bryan Ferry as a client, working with him worldwide through the Clair Global group. And that’s made my own job so much easier. “Having had two tours out with them at the same time, I can honestly say that from now on Brit Row will always be my first choice of vendor. I’m always so impressed with their global contacts. I’ve noticed over the last year or so that this resource has really taken what Brit Row can do up to the next level. That spills over into having the Clair support too. “Our Account Manager Dave Compton is amazing I can call him about any territory in the world and he has the solution. “I’d never worked with Brit Row prior to coming into this three years ago, but I’ve been bowled over by their service ever since,” says King, whose PM duties for this tour crossed over with Supergrass, another Brit Row client.
