    Input Selection PAM2-3G16 ships with User Presets 1-5 programmed to instantly access SDI1, SDI2, AES, Analogue and Optical TOSLINK inputs. Selecting these presets will directly route either input signal to the bargraph display. These User Presets may be overwritten however and customised as required.

    | 17 2.4.3 AES Input Optical Input – PAM2-3G16 is unique amongst rack mount audio monitoring products in that 2.4.4 it features a TOSLINK Optical Input. The Optical Input is selected via Factory Preset 5. When Optical is selected, AES channel 8 is replaced by the signal received via the Optical connector. This input may be used to connect directly to a Set Top Box, DVD or CD player and can decode Dolby Digital or Dolby Digital Plus encoded signals.

  • Page 20 The selection may be saved as a User Preset for instant recall (see Saving User Presets). Note; Split Mono selection uses the Assign Matrix section of the PAM2-3G16 in order to create a pair of non consequential audio channels. When a Split Mono pair is defined, the Assign Matrix represents the resultant signal selection as illustrated below.

  • Page 21: Front Switch Monitor Select Mode

    | 21 Front Switch Monitor Select Mode In order to further enhance hands on operation of PAM2-3G16, an operational mode exists which enables the user to toggle between the standard front panel operation of 8 user preset recall switches below the OLED displays and direct access to up to 6 monitoring mode selector buttons.
  • Page 22 Lt Rt (Dolby Only) By pressing the LtRt button when PAM2-3G16 is decoding a Dolby E, D or DD+ signal, a stereo Downmix will be selected. This is the default listening/monitoring condition for a Dolby signal and is derived using the originally authored Dolby metadata thus enabling the user to hear the effect of stereo downmixing as heard by the consumer.
  • Page 23 When a Dolby E, Dolby Digital or Dolby Digital Plus encoded audio pair is selected, PAM2-3G16 will automatically decode the signal into its component parts and name the stems according to the Channel Coding information carried within the Metadata.

    Setup Menu 1 includes options for different Scales, Reference Levels, Peak Hold, Dolby E programme, Dolby E Video compensation delay, Video Window and Audio delay. By highlighting and selecting a parameter, the user can scroll through the available options and tailor PAM2-3G16 to suit their needs .

  • Page 30: Dolby E Video Delay (Dolby Version Only)

    The Hold parameter activates a peak hold indication when switched on. 2.12.2 Dolby E Video Delay The PAM2-3G16 features a 1 frame (40 ms) video delay setting which can be inserted into the Downconverted video display to compensate for the latency caused by decoding a Dolby E signal. If selected and activated, the delay will be switched into the video signal path automatically when a Dolby E input signal is detected and decoded.

  • Page 31: Audio Delay

    | 31 2.12.3 Audio Delay The TSL PAM family of audio monitoring units is unique in that they feature the ability to insert up to 250ms of delay into the audio monitoring signal path (headphone, internal speaker or variable level outputs).
  • Page 32 This setup may suit applications such as MCR or QC Suites where specific programme content occasionally requires the attention of full range or 5.1 listening or when two or more PAM2-3G16 operators share a common external speaker system.
  • Page 33 | 33 2.12.11 Energy Saver Mode (ScrnSave) PAM2-3G16 features an energy saving mode which dims the OLED displays after a defined period of time when activated. The ScrnSave button within Setup2 menu access 4 preset time settings after which the OLED displays will dim, reactivated once a button is pressed or an encoder turned by one click.

    ITU-R BS1770 Loudness Setup menu is accessed from the Main Menu. PAM2-3G16 aims to provide the user with a set of tools which comply with the recommendations of both the ATSC (A85) and EBU (R128) Loudness committees whilst giving the flexibility to tailor operation to suit local requirements.

  • Page 37: Target Level, Limit Threshold And Red Line Alarm

    PAM2-3G16 will continue to measure the Loudness of the highlighted audio components. In this mode of operation PAM2-3G16 does not make the assumption that the audio signals are present in the correct SMPTE channel order for 5.1 sound – by selecting the channel components individually, non SMPTE order 5.1 audio can be chosen and measured.
  • Page 38 The Limit Value at which a Loudness value ‘red lines’ can be set at up to +6 LU above the Target Value. At the point at which the ‘Red Line’ limit is reached, PAM2-3G16 triggers an output GPI via the D15 rear connector. This can be used for external Alarm notification and/or to control a third party Loudness control device.

  • Page 39: Start, Stop And Reset Triggers

    | 39 2.14.3 Start, Stop and Reset Triggers In order that Loudness measurement is targeted towards specific programme content, PAM2-3G16 is equipped with the ability to Start and Stop (pause) measurement cycles. These functions can either be triggered manually from the on screen button or from a GPI via the D15 connector at the rear of the unit.

    Note that the +5V power from this connector is intended to drive a "1-of-N" LED. If multiple LED’s are to be used simultaneously, then a small external supply will be needed. An internal resistor within the PAM2-3G16 prevents the +5V rail from being shorted but limits the current available. PAM2-3G16...
