Page 8: Checking The Firmware
CHECKING THE FIRMWARE When the system setup mode has been activated and the readout displays System , rotating the SELECT knob clockwise will cycle through the following: Inputs - This configuration setup allows you to select the input sources that will be enable during monitoring. - Page 9 INPUTS SETUP (for all modes) A fully assembled AMS8 has multiple program inputs (75 Ω , 110 Ω , Analog, SDI 1 (A) Groups 1 and 2, SDI 1 (A) Groups 3 and 4 and SD1 2 (B) Groups 1 and 2 and SDI 2 (B) Groups 3 and 4.
- Page 10 ASSIGNMENT SETUP (for Mode 1 only) The AMS8 has the ability to monitor multiple inputs, IN1 to IN4 at 75 Ω , 110 Ω and Analog, as well as, eight digital programs within one of the two SDI streams. The Assigns setup allows an operator to assign any one of these inputs to the four INPUT select pushbutton switches for rapid selection.
- Page 11 CONFIGURING A PRESET (Presets can only be configured when operating in MODE 2) Press and hold a PRESETS button for approximately three seconds. If preset button A is selected, the readout should display A L1 above the SELECT knob and either O ff or a level between - 15 and + 15 above the VOLUME knob. Rotating the SELECT knob in either direction cycles through the eight available sources that are displayed on the LED meters.
- Page 12 OPERATING IN MODE 1 (Default for units with Dolby Decoder installed) The AMS8 would be set to operate in Mode 1 when dealing with multiple channels PCM or Dolby digital signals. A Dolby decoder must be installed in the unit. Input sources can be either PCM, Dolby AC-3 or Dolby E.
- Page 13 display M ute. The two channel PCM signal may also be converted to a ProLogic Surround version by rotating the SELECT knob in either direction. The readout will display PCM /PL . The ProLogic signal comprises Left, Right, Centre, Left rear and Right rear. These signal levels are displayed on the CH1, CH2, CH3, CH5 and CH6 LED bar graphs respectively.
- Page 14 If the signal is lost through interruption or if an internal error occurs and the unit cannot lock to the incoming signal, the readout will indicate N o Lock. The four PRESETS pushbuttons may be used to listen to the signals solo, discretely or summed (for phase checking).
- Page 15 OPERATING IN MODE 2 In Mode 2, the AMS8 operates as a multi-channel monitor box with the ability to proportionally mix any of the inputs to the left and right monitor channels. All inputs must be PCM. The unit will accept eight inputs; four unbalanced and four balanced sources.
- Page 16 Select SDI 1/2 for SDI 1 (A) Groups 1 and 2 Select SDI 3/4 for SDI 1 (A) Groups 3 and 4 Select SDI 5/6 for SDI 2 (B) Groups 1 and 2 Select SDI 7/8 for SDI 2 (B) Groups 3 and 4...
- Page 17 OPERATING IN MODE 4 The AMS8 would be set to operate in Mode 4 for a task specific application. In Mode 4, the types of signals that can be connected to the input source connectors are strictly defined. Inputs 1, 2 and 3 must be PCM and input 4 must be a multi-channel Dolby signal.
