PAM PiCo Touch – Quick Sheet Change Scale & Loudness Setup Meter Source Select Bargraph Options Touching the scale area allows access to Scale setup, Loudness Setup and Display mode (Moving Coil or Bargraph) Touch the legend of the meter sources, to open and select from the list of input sources. Sources may be named to your liking. Change colours, Over/Normal/Under levels. Assign ‘Type’ to specify what role the Bargraph represents e.g. Left, Right or other.
Basic Operation Touch Zones & Navigation The PAM PICO TOUCH is a multi-touch sensitive device allowing for both slides, tap and Press & Hold functions. The basic operation of the PAM PICO TOUCH is based on simply touch the area of the screen that you would like to interact with. Touching Touching a specific area, will call up the relevant menu points and allow you to alter settings in an instant. Exiting a menu is always done by hitting the top menu bar on the left hand side.
Meter Views – an Overview This section gives you a quick overview of the different views available in the PAM PICO TOUCH. StarFish View The StarFish view builds on the heritage of the famous TSL Products MSD meter range and features a Vectorscope alongside a bargraph section allowing for both level and loudness views. In addition, the four text readouts are displayed on the upper right section of the screen.
Graphical LEQ View The Graphical LEQ view allows for several different simultaneous views. On top of the four standard text readouts and phase meter, it features level Bargraphs adhering to the defined scale, while the dual Loudness bars are referring to the defined loudness scale. In essence, this means that two independent scales are viewed at the same time. Furthermore, the Loudness level is plotted against time as a graphical track on screen, allowing for a historical view.
Source & Audio Routing Understanding the Basic Signal flow of the PAM PICO TOUCH As you are probably already aware, the PAM PICO TOUCH is a quite complex product with a lot of different signal routing sources and destinations i.e. SDI, AES, Analogue as well as internal signal sources with destinations of Bargraphs, Text Readout, StarFish, FFT, Loudness measurement and Downmix possibilities.
1 - Source Selection – Choosing your input Touch the legend bar of the Bargraph and the source selection list will open up Touch the Top bar to access the Source Selection Menu on the right hand side of the display. Make sure to point to the specific Bargraph, that you want to alter the source for. The source selection allows you to choose between a number of Internal and External sources (see below for details on the Source list) Scroll the list to find the specific source that you are looking for.

Creating your own Labels In addition to the default label list, you may design your own. The process to enter the Source Label Assign menu is the same as above, but instead of selecting one of the default labels, scroll pass the default labels and tap the header called ‘Edit Labels’. Below this header, you will see an additional 32 user labels that may be customized to your liking. - Hitting the ‘Edit Label’ header will bring up the keyboard and allow you to enter your desired label.
Hit the Header called ‘Labels Assign’ and you will see the different types. INP L R C LFE LS RS CL CR CS LOUD OFF As might notice, a lot of these types are identical to some of the Default Source labels mentioned in the Label section above. If you have chosen one of these default labels, you can simply select the Type to be ‘INP’ for ‘Input’. This means that that the PAM PICO TOUCH will look to the Input Source Label to learn what type of signal your source is.
Set Up Bargraph Options Colours, Colour level & Bargraph Width The Bargraph options menu that we already talked about in the Source and Touch the Bargraph to access the Bargraph Options Menu Audio Routing section, contains a number of other relevant parameters for defining the look and behavior of your Bargraph elements i.e. Labels Assign, Bargraph Width , Colour Normal, Colour Under, Under Level. Touch the specific Bargraph you want to alter, and the menu will open up on the right hand side.
Under Level Range: 0 to -25dB The ‘Under Level’ determines when the signal is considered ‘Under’ the normal level. Set Up Scale & Loudness Format Touch the Scale area to access the Scale & Loudness Menu Touching the Scale area of the Bargraphs will open up the Scale and Loudness menu, allowing you to define what scale and Loudness format you want your meter to adhere to. The parameters in this menu counts: Scale, Under Level, Loudness Preset, Loudness Setup, Loudness Option.
If you select ‘User’, two additional folders open up called Loudness Setup and Loudness Option. These two folders enable you to completely customize the Loudness measurement to your exact specifications. Loudness Setup The Loudness Setup folder allows you to customize the loudness settings of your meter. You may use one of the Loudness presets as a starting point.
Gate Level (-a) Range: -8 to -20 dB (1 dB steps). It is the high level parts of a program which are often of most interest for assessing compliance with broadcast criteria. To prevent an extended length of low level program content reducing the averaged loudness value to a degree that affects the measured value, the meter has an optional gating function.
During the Loudness capture, you may now toggle the capture between ‘Start’ and ‘Pause’. The overall resulting loudness readings will express the summarized capture of all audio above 70dBFS from the last Reset. Hitting ‘Reset’ will re-initiate the Loudness Capture and measures. Overall, the Start-Pause mode allows you to manually start and stop the capture during breaks or audio that you do not wish to consider in the overall loudness readings.

Overall, the Start-Pause mode allows you to manually start and stop the capture during breaks or audio that you do not wish to consider in the overall loudness readings.
Set Up Meter Text Read-out Hit the Text Read-out area to open up the Meter lines menu. The menu contains the settings for the four Text lines of the PAM PICO TOUCH display. Line 1 is always in a bigger font, while 2, 3 and 4 are small font. It is completely up to you what information you want to display in each line.
Set Up StarFish, Timecode and Phase Meter Touching anywhere in the StarFish area will open up the StarFish and Timecode menu including: Compressor, OP-mode and Timecode. Compressor The compressor section allows for different performance parameters to be set up. Fast / Slow parameters controls the Phase correlation responds time. In particular, when reviewing phase relation of low frequency content, the ‘slow’ position might come in handy.
Timecode The Timecode section allows you to choose what timecode should be displayed below the StarFish area; Internal Timecode, incoming SMPTE Timecode or off position. Incoming SMPTE code must be feed through the Right Analogue input (input2). PAM PICO TOUCH is capable of automating Loudness capturing based on incoming Timecode, a very handy and time saving production feature.
‘On-screen’ Button sets Horizontal & Vertical The PAM PICO TOUCH features a set of eight buttons both horizontally and vertically. In fact both the horizontal and vertical set of buttons feature no less than three sets of eight buttons, that may be changed between by a simple ‘swipe’ across the button bar. Every one of the buttons can be customized to perform exactly the function you require in a matter of seconds, rendering an extremely powerful ability to restructure the user interface to your needs.

Loudness Automation PAM PICO TOUCH features a unique ability to automate and instantly recalculate Loudness results based on incoming timecode. The only requirement is that you have an LTC / SMPTE timecode available along with your audio signal. The benefit is a much more efficient workflow and a drastic reduction in time spent on measuring the final Loudness result.
Loudness Logging The PAM PICO TOUCH is capable of streaming its loudness data to its companion PC application PiCo Logging, which is available as a download free of charge for all PAM PiCo TOUCH and PiCo1, PiCo2, PiCo5 models from here: http://www.tslproducts.com/support/softwareupdated-applications/ The Loudness Logging data is captured through the USB connection and allows for detailed review, analysis and reporting of the different logged parameters.
Using PAM PiCo Matrix II Setup Editor The PiCo Matrix II Setup Editor, allows you to quickly and easily get an overview of the sources and destinations of your meter. Also, the bargraph width, normal and under colour can quickly be set up via PiCo Matrix. Furthermore, PiCo Matrix for easy back and replicating the same setup across several meters.
Set Up Picture Preview The SDI Picture preview function of the PAM PICO TOUCH is enabled/disabled by hitting the ‘Picture’ button defaulting to the lower position of the vertical button set. Upon pressing the ‘Picture’ button, the embedded video stream of the incoming 3G/HD/SD SDI input is super imposed on top of the regular metering information. Altering Picture Preview Position The Picture Preview on screen position may be change by simply ‘dragging’ it onto the desired position of the screen.
Security Lock The PAM PICO TOUCH features a security lock function allowing you to block for access to background setup parameters and menus through a four digit code. The security lock function is called up by pressing the TSL Products logo in the lower left corner of the screen. Security Locking your device The PAM PICO TOUCH is shipped with a default un-locked factory setting. In order to enter your own code, hit the backspace button and delete the four * characters. Now enter your own four digit code.
The Advanced Setup Menu The Setup Menu The Setup Menu holds the access to all of the background parameters of your PAM PICO TOUCH. Most of the functions we have already covered in the earlier sections. The setup menu is reach by pressing the ‘Setup’ button. Default position is on the first vertical button set. About The ‘About menu’ holds technical background information about the software and hardware configuration of your unit as well as the settings for the External Monitor setup (HDMI out).
Instruments & Display Tools Bargraphs The standard Bargraphs can be used to view numerous different representations of the incoming audio e.g. level according to the selected scale, various loudness parameters, sum/difference and more. PAM PICO TOUCH allows up to 16 simultaneous Bargraphs to be viewed at the same time. Eye Width Range: 10% - 100% All SDI capable PAM PICO TOUCH feature the Eye Width Parameter as default feature.
Goniometer – Vectorscope The Goniometer is automatically chosen when StarFish® or JellyFish® are enabled and only 2 channels are routed to the Bargraph section (please the Matrix section for further details). The Goniometer or Vectorscope displays phase and amplitude information on the Left and Right input channels. Phase correlation When the Goniometer, StarFish® or JellyFish® are selected, the left most part of the display is a phase Bargraph with purple graticule lines.
JellyFish™ DK Technologies’ trademark ‘JellyFish®’ display was first launched on audio only meters. It was later developed to provide the alternative ‘StarFish® display and both included in the PAM PiCo. Both modes provide a picture of the surround audio field in 5.1, 6.1 or 7.1 channel modes. The display has the front center channel arranged towards the top with other directions are marked. The image here shows the StarFish® mode with equal audio on all legs.
After hiding the Analyzer panel, the left panel part of the screen shows the individual audio level Bargraphs for the elements that make up the surround (or stereo) signal. The Bargraph in the right panel shows the instantaneous loudness value. The Loudness Capture functions are described in detail in the Capture section. The ‘Integtr’/’Shorttrm’ button allows for toggling between the two different Loudness measures.
Loudness & Terminology About Loudness Loudness measurements differ from conventional signal amplitude measurements in that they are also influenced by the frequency content of the signal and the duration of transient components. The way these various elements are handled to give a value for display has been defined by the International Telecommunications Union in their standard ITU BS1770 which is the only loudness standard to have achieve any degree of international acceptance.
Dynamic Gated Integrated Loudness (I) The dynamic gated loudness is a long term measurement (an integration over the entire material) based on the momentary loudness. It uses a dynamic gate at -10 LU under (dB relative to) the absolute gated loudness which means that the measurement is on hold if the momentary loudness gets under the dynamic gate. It is always the last value of the dynamic gate which is used on the material.
Technical Specification PAM PICO TOUCH Hardware GPIO – External Hardware Control PAM PICO TOUCH features three hardware GPIO’s using pin 5 and 13 on the 15 pin Sub-D connector. It allows for up to three external hardware control functions to be remote controlled through shorting to ground (pin 11).
