    3.3.4 Power On Power on the M16 using the main power switch located on the rear panel adjacent to the IEC connector. NOTE: The M16 retains the latest settings of every microphone parameter in non-volatile memory. Therefore these settings are not lost when the unit is not powered and are automatically re- called when power is applied.

  • Page 19: Mute Switch

    Channel Control Section The M16 Channel Control Section provides complete control over all microphone channel parameters. While it is possible to control a single channel, the M16 also provides the ability to quickly select and simultaneously control multiple chan- nels.

  • Page 20: Channel Control Section Parameters

    Pad Switch: Pad Enabling the Pad switch attenuates the selected microphone chan- nel(s) by -20dB. This is useful if feeding the M16 with very high line level signals, although the M16 can accept +11dBu line level signals at minimum gain (+10dB).

  • Page 21: Headphones

    Headphone impedances below 150 ohms can still be used, however, the audio level will be reduced. It is possible to bus link the PFL bus of multiple M16 units. See sec- tion 3.7 Monitoring the PFL bus on multiple M16 units.

  • Page 22: Connecting The Madi Output

    Connecting the MADI Output The MADI optical Duplex SC housing is located beneath the PFL bus link connectors on the rear panel of the M16. This comprises of two optical connection points, one transmit (Tx) and the other re- ceive (Rx). See FIG 3-2.

  • Page 23: Word Clock

    BNC T-piece should be employed (not supplied). The device at the end of the word clock chain will require termination with a 75ohm load. If this device is the M16, then it is necessary to fit a 75ohm ter- minator (not supplied) onto the BNC T-piece.

    Power for the RM16 is supplied via an external 6v DC 3.3A/20W power adapter.The power adapter is designed to operate through the following AC mains voltages. Mains Voltage: 100v - 240v AC Mains Frequency: 50/60Hz M16 Microphone Amplifier Revision MA2005-7...
  • Page 27 For ease of understanding, the remote control connections on both the RM16 and M16 are labelled In and Out. However, it is worth knowing that these two connectors are actually wired in parallel, therefore providing a robust communications backbone. If any de-...

    FIG 4-5. Rear panel of RM16 Connect the other end of the communications cable into the RS-485 IN XLR-3F connector located on the rear panel of the first M16 of the system. Any M16 can be assigned to be the first in the chain.

  • Page 29: Power On Sequence

    This is referred to as Enumeration. Note: When connecting an RM16 to an M16 for the first time, the Remote LED on the M16 front panel may flash. This is indi- cating that the connected system requires Enumeration. If using multiple RM16s within a system, choose just one to run the interrogation sequence.
  • Page 30 NOTE: If in a sub-menu and no buttons on the RM16 are pressed for a period of 30 seconds, the Control Menu will return to the Root menu. M16 Microphone Amplifier Revision MA2005-7...

  • Page 31: Control Menu

    FIG 4-7. RM16 root menu 4.10.3 Naming M16 units It is possible to give each M16 within the system a unique name (maximum of 16 characters) via the RM16 controller. The name is stored in EEPROM memory within the M16 itself, therefore the rack name will be recalled when interrogated via the RM16.

  • Page 32: Naming M16 Channels

    4.10.4 Naming M16 channels It is possible to give each of the 16 channels within an M16 a unique name (maximum of 8 characters) via the RM16 controller. This name is stored in EEPROM memory within the M16 itself, therefore all channel names will be recalled when interrogated via the RM16.

  • Page 33: System Integrity

    To confirm correct operation over the communications backbone: M16: Check that the red Remote indicator on the front panel is illu- minated. When using multiple M16s within a system, the Remote LED will illuminate when that rack is selected within the RM16.

  • Page 34: Rm16 Meters

    4.12.1 M16 selection Selection of which M16 is currently being controlled and metered by the RM16 is performed from the Root menu. To select which rack is to be controlled, press the - Rack ( ) + buttons located beneath the menu screen.

  • Page 35: Channel Selection

    Pad Switch: Pad Enabling the Pad switch attenuates the selected microphone chan- nel by -20dB. This is useful if feeding the M16 with very high line lev- el signals, although the M16 can accept +11dBu line level signals at minimum gain (+10dB).

  • Page 36: High Pass Filter

    GENERAL NOTE: Communication is bi-directional, so it is pos- sible to alter settings directly on the M16 and the RM16 (if se- lected to that channel). Any changes made directly to the M16 will be reflected in the RM16. This applies to Gain, Pad, Phase, Reverse, Phantom Power and High Pass Filter settings.

  • Page 42: Cadac Usb Reprogramming Utility

    APP-4 CADAC USB ReProgramming Utility CADAC will, from time to time, release firmware updates for the M16 in order to improve performance and enhance facilities. Your local CADAC distributor will keep you informed when such up- dates are available. The following sections explains how to install the new firmware into the M16 using the USB ReProgramming Utility.
  • Page 43 APP-5 Running the Sam ReProgramming Utility Make sure that the M16 is switched on and the USB cable is con- nected to both computer and M16. ■ Click on the Start button on the Windows Taskbar. ■ Select All Programs > Sound Automation Manager > USB ReProgramming Utility.
  • Page 44 SamFlasher will interrogate the USB port and display which devices are attached. In this case it will be the M16. Details of the M16 will be displayed, giving Unit ID, Unit Description, Unit Serial Number and currently installed firmware version.
  • Page 45 SamFlasher will then display the new installed firmware version. Further confirmation can be obtained by viewing the firmware ver- sion via the M16 front panel menu as detailed in the following sec- tion. Repeat this process for any additional M16 units.

  • Page 46: M16 Software Version

    PFL switches are enabled and simulteneously press and hold the Inc, Dec and Rev buttons on the front panel. The version numbers will be displayed for both the M16 control software and the MADI firmware. The +18dB LEDs indicate the MADI firmware version while the - 36dB LEDs indicate the control firmware version.
