resonances at different frequencies. It is essential for the frequency response of both speakers ROOM ACOUSTICS to be similar if you are to hear the full depth and space potential of your speaker systems. A loudspeaker system could be adjusted to measure an acoustically flat frequency response EQUALIZING across the entire audio range of 20Hz to 20,000Hz. -

The MQ108 can also be connected between the preamplifier outputs and power amplifier inputs on a receiver or integrated amplifier-preamplifier. It is not recommended that the MQ108 be connected to a tape monitor loop or signal pro- cessing loop, since the high output levels could possibly overdrive the MQ108 inputs. -

FREQUENCY PROGRAMMING table on the chart included in this manual and also attached to the inside of the MQ108 cover. If no capacitors are inserted in a filter section, turning the control will have no effect. Both capacitors must be used in the same section for proper operation. - Page 11 The first bank of sections is 1 through 4, and the second bank is 5 through 7. Once the programming has been finished, and the desired results achieved, the cover should be replaced on the MQ108. No adjustments or changes should be made to the MQ108 pro- gramming without using an analyzer to check the results.
