[. . . ] If no other adjustments are to be made at this time, press the SETUP Push-button to exit the Setup Controller Mode or proceed to the next desired Setup Controller Mode for adjustment. Figure 16 3. Rotate the LISTEN (Select) Control until the Front Panel Alphanumeric Display indicates "TRIGB LVL 12V". Refer to figure 17. D/A Control (McIntosh MDA1000) When the McIntosh MDA1000 D/A Converter and MCD1000 CD Player are connected to the C1000 Controller there are special functions to enhanced operation of the D/A Converter with the C1000. The following steps activate these functions: 1. Press the SETUP Push-button once to access the Setup Controller Mode unless the C1000C is already in the Setup Controller Mode. Rotate the BALANCE (Menu) Control until the words "D/A CTRL OFF" appears. If no other adjustments are to be made at this time, press the SETUP Push-button to exit the Setup Controller Mode or proceed to the next desired Setup Controller Mode for adjustment. Triamp (Balanced Outputs) The C1000P and/or C1000T Preamplifiers provides three Balanced XLR Output Connectors for each channel. One Output is labeled MAIN (non-switched) and two additional Outputs MAIN/SPKR1 and MAIN/SPKR2 (switched On or Off by using the HR54 Remote Control ). Outputs MAIN/SPKR1 and MAIN/SPKR2 may be configured to remain On along with the MAIN Output for use in systems with three Power Amplifiers per channel. To change the MAIN/SPKR1 and MAIN/SPKR2 Outputs perform the following steps: 1. Press the SETUP Push-button once to access the Setup Controller Mode unless the C1000C is already in the Setup Controller Mode. Figure 20 3. Rotate the LISTEN (Select) Control until the Front Panel Alphanumeric Display indicates "D/A CTRL ON". Refer to figure 21. Figure 21 25 4. Rotate the BALANCE (Menu) Control until the words "D/A INP1 ON" appears. Refer to figure 22. trate how to rename the AUX Input to DVD2. When the Input Selector is rotated to select what was originally the AUX Input, DVD2 will now appear on the Front Panel Alphanumeric Display. Notes: 1. Unused Inputs may be switched Off so they will not appear when going through the input source choices using the LISTEN Control, RECORD Control or when using the Remote Control or Keypad. Refer to figure 25. Figure 22 In the following step the memory of C1000C will be updated to reflect the assigment of active Digital Inputs on the MDA1000. This will prevent having to go through unused inputs when changing the D/A Inputs by using either the C1000 Front Panel Controls or supplied Remote Controls. Rotate the LISTEN (Select) Control to select On or Off for "D/A INPut 1". Rotate the RECORD (Select) Control to select the next input, "D/A INput 2". Rotate the LISTEN (Select) Control to select On or Off for the next "D/A INPut 2". [. . . ] By developing electronic circuits the Figure 103 meters are made to respond to short intervals with an accuracy of 95%!To permit the eye to see such high speed motion, the electronic circuits that drive the meter pointer are time stretched. Special logarithmic circuitry allows the meter to indicate a 60dB plus range, without resorting to a Meter Range Switch. Power Supply Circuits To compliment the design of the C1000, there are two indentical fully regulated power supplies, one for each channel. [. . . ]
