User manual SMART DEVICES SHOWGRAMMER II

[. . . ] A CENTER FILL level control lets you easily balance the rear wall speakers against the Left Surround and Right Surround speakers. You can easily select between the SHOWGRAMMER II mode and the regular LS-RS mode with the push of a button. Built-in pink noise lets you easily set the surround channel levels, and if you have equalizers installed, the pink noise source gives you a signal that a Real Time Analyzer expects. This product even has a built-in subwoofer output signal for adding those usually missing low frequencies to your surround system.

SERIAL # _______________ 3 INSTALLATION PRECAUTIONS Noise Interference may result if this product is placed too close to an operating television set or a computer, or if it is placed on top of an amplifier or power conditioner product. High temperatures are detrimental to the performance and longetivity of electronic equipment. In addition, there is a volume adjustment knob (marked CENTER FILL) on the front panel for setting the rear wall (CS) speakers' volume relative to the Left and Right Surround volume. Typically, the CS channel volume is set about 3dB higher than the Left and Right Surround channels. You may want to experiment with the CENTER FILL control to get the best effect in your particular listening room. Also, there is built-in pink noise which can be used to help balance the levels between the surround channels if any adjustment is needed. To activate the pink noise, push down the DIP switch marked ON. Then to send the noise to a particular channel, push down the DIP switch corresponding to the desired channel. Be sure to push all the Pink Noise DIP switches back up when you are finished with the pink noise. There are six OUTPUT LEVEL trimpots which are used to adjust the output levels if needed to balance the levels between the various surround channels. In most cases, these can be left at the factory settings. If you need to adjust these, use the supplied alignment tool or a small jeweler's type screwdriver. If you turn them all the way to one end, they will click slightly as you continue to turn them. [. . . ] This produces three separate surround channels. This is the format you will normally use with digital soundtracks. The LS-RS format (pushbutton out) is used for playing matrix decoded stereo soundtracks. This format can also be used when playing a digital soundtrack if the resulting sound with the CS (rear wall) speakers playing is not as you desire. [. . . ]
