Model SEQ

Input Gain ControlCalibration/Adjustment: The pre-amp circuit built into the SEQ iscapable of 26dB of gain. Separate left and right channel input gain andadjustments are made via two access holes in the front cover.Adjustment to the input gain may be necessary to match the source(tape deck, tuner or CD) output level to the input sensitivity of the systemamplifiers. If this adjustment is set too low, the source may distortbefore the system is able to achieve full power. If the input gainadjustment is set too high, the internal circuitry of the SEQ and/orsystem amplifiers may distort.There are two clipping indicators, one for input stage clipping and one foroutput clipping.Insert a tape or compact disc recorded at high level into the source unit.If the source unit has a balance control, ensure that it is set to center.Set the SEQ filter controls flat (0dB). Using the small plastic screwdriverincluded with the SEQ, adjust the input gain trim pots fullycounterclockwise. The trimpots are 20-turn pots. Turning each pot morethan 20 full turns counterclockwise will ensure that left & right channelsare matched before the gain adjustment procedure begins. If the sourcehas a volume control, set it from approximately 1/2 to 3/4 full output.With the SEQ volume control rotated completely counterclockwise, beginby turning one input gain pot clockwise (count the number of turns) untilthe red input clip indicator flashes. Rotate the other input gain trimpotthe same number of turns as the first. Minor input gain adjustments maybe necessary to achieve left/right balance or for higher level tapes orcompact discs. Setting filter controls at a high boost position may alsocause the preamp output indicator to flash, requiring a reduction in inputgain.7
