[. . . ] These symbols warn that there are no user serviceable parts inside the unit. Do not attempt to service the unit yourself. Refer all servicing to qualified personnel. Opening the chassis for any reason will void the manufacturer's warranty. If liquid is spilled on the unit, shut it off immediately and take it to a dealer for service. Disconnect the unit during storms to prevent damage. Unpack and inspect the RPQ160 box and package. If obvious physical damage is noticed, contact the carrier immediately to make a damage claim. We suggest saving the shipping carton and packing materials for safely transporting the unit in the future. Please complete the Warranty Registration Card and return it to the factory.

HIGH SHELF: Low Pass Filter control; adjusts the amount of high frequency rolloff from 1 kHz up to 20 kHz for the entire output of the RPQ160. NOTE: THERE IS NO BYPASS SWITCH FOR THE LOW OR HIGH SHELF FILTERS - SIMPLY TURN THE LOW SHELF COMPLETELY COUNTERCLOCKWISE, AND THE HIGH SHELF COMPLETELY CLOCKWISE TO BYPASS THESE CIRCUITS. LEVEL: Adjusts the overall signal level of the RPQ160. NOTE: The following three descriptions are identical for all four bands of equalization. FREQUENCY: Selects the frequency to be boost or cut. The band frequency ranges are listed below: Band 1: 70 Hz to 1. 5 kHz Band 2: 150 Hz to 3 kHz Band 3: 300 Hz to 10 kHz Band 4: 600 Hz to 20 kHz WIDTH: (Q): Varies the shape or width of the equalization being boost or cut from . 3 to 3 octaves wide. LEVEL: Boosts or cuts the signal of the indicated band from -15 to +15 dB. Power Switch: Applies power to the RPQ160 when the unit is connected to a properly grounded ac outlet. [. . . ] The Low Shelf Sweep Diagram shows the response curve of the Low Self filter at its minimum and maximum setting. Set at 16Hz O dB OPERATION Cont. Shown below is the typical symmetrical response curve of a swept parametric band filter with the Frequency control set at 1 kHz, the Level set at +15 and -15 dB, and the Octave control set at . 3, . 5, 1, and 3. These curves remain consistent over the frequency spectrum, they simply shift to whatever frequency setting is indicated by the Frequency control. The shape is most narrow when the OCT control is set at . 3, and is widest at the 3 setting. 20 15 10 5 Amplitude, 5 dB/division Set at 500 Hz 20 40 80 160 320 640 12k 16k 20k Frequency (Hz) LOW SHELF SWEEP DIAGRAM The High Shelf Sweep Diagram shows the response curve of the High Self filter at its minimum and maximum setting.
