User manual SMART DEVICES SG1100

[. . . ] This allows you to match the levels between the players. Installation Locate the SG1100 close to the stereo processor and the digital processor. There are 3 cable sets which may be ordered with the DM6. One cable set is for connecting the DTS digital system to the DM6, and the other 2 are for the Dolby DA20. These cables are about 30 inches long, so keep this in mind when selecting a location. Also install any additional power amps if needed at this time (e. g. , for split surrounds). [. . . ] Make a new wiring harness which will connect the outputs of the stereo processor to the OPTICAL INPUTS on the top left terminal strip on the rear of the SG1100. Please observe standard wiring practice, i. e. , use 2 conductor + shield cable and ground the shield at one end only. INPUT CARD ONE OCTAVE EQ (3) SUB BASS EQ OUTPUT CARD FORMAT CARD DUAL ONE OCTAVE EQ FOR SURROUND CHANNELS 3 The first model of the SG1100 had on DB25 connector wired for the DTS system. The first production run of the DM6 has one DB25 connector on the rear panel. This may be used for either the DTS or DA20 connection (with the appropriate cable) although the labeling on the front panel pushbuttons indicates this input as the DTS. The other digital input is labeled DIG on the front panel pushbuttons. If both DTS and DA20 processors are being used on the same DM6, the the DA20 will have to be wired to the input terminal strip on the DM6 while the DTS will plug into the DB25. The second production run has an additional DB25 socket on the back of the p[roduct so that plugging in both the DTS and the DA20 simultaneously will be possible without having to wire directly to the terminal strips. Now wire the digital processor outputs and control lines to the appropriate inputs on the rear of the SG1100. If you are using the DTS System and have ordered the DTS to SG1100 cable from SMART, it is only necessary to plug the cable in, and all connections are made for you. This cable, DM6-DTS, has a DB50 plug on one end which plugs into the mating connector on the DTS. The other end has a DB25 plug which plugs into the DB25 receptacle on the rear of the SG1100. If you are wiring a Dolby DA20, connections will be made to either the DIGITAL INPUTS terminals on the bottom right terminal strip or to the DB25 connector on the rear of the SG1100. The 2 DA20 cable sets are configured as follows: The current models have two DB25 connectors. First, remove the Input Switching Card, and then plug in the Pink Noise card. It is necessary to remove the Input card because if both were plugged in simultaneously, both cards would be fighting for control of the signal buss. Please note that the original Pink Noise card does not have LS and RS outputs. It is necessary to modify the pink noise card so that the one surround channel feeds LS and RS. Simply add a jumper wire from Pin 4 to Pin 5 on the Pink Noise Card. These are 4th and 5th Please note that the DA20 Sub-Bass output is 10 dB lower than the stage channels. The Sub-Bass channels on the DM6 Input Switching card have sufficient range to accomodate this lower level. The factory settings on the DM6 will already be set to compensate for this lower level on the second set of digital inputs. The factory settings on the DM6 for Trimpots on the OUTPUT CARD allow final level matching. 5 the first set of digital inputs will be set for DTS levels. If you hook a DA20 up to the first set of digital inputs (i. e. , you are connecting to the first or only DB25 on the DM6), you will probably have to adjust the Sub-Bass level upward (using the Sub-Bass trimpot on the DM6 Input Switching Card) to accomodate the lower Sub-Bass level from the DA20. If you must make adjustments to the factory settings on the SG1100, then use the trimpots on the INPUT SWITCHING card first. [. . . ] Both top and bottom sections are used for the split surrounds. The top is Left Surround and the bottom is Right Surround. This same card is also used for the optional SubBass EQ, but fewer parts are installed. Optional 1/3 octave EQ cards may be installed for stage channels. Dual one octave EQ card for split surround channels. [. . . ]
