Each band has separate Frequency, Q and Level controls allowing extremely active sound creation. Also, it features the Total Level Control that serves to minimize the volume difference between the normal and the effect sounds. Moreover, it provides three input jacks: two standard phone jacks (MIC, INST) and a pin jack (LINE), and two output jacks a standard phone and a pin, which enables various setups such as with audio and visual equipment and recording equipment as well as an electronic musical instrument. The RPQ-10 is one of the BOSS Micro Studio Series, and by using a rack mount adaptor RAD-10, any two of the Series can be mounted on a standard 19" rack (EIA-1U). ■OUTLINE The RPQ-10 is a 2 band parametric equalizer, and each band features individual controls; Frequency Controls, Q Controls and Level Controls. These allow you to adjust the frequency response of the input signal in extreme subtleness. *The Low and High bands have different frequency ranges but otherwise work exactly the same. Frequency Controls These select the frequency to be boosted or cut in the range shown below. (Refer to Fig. 1) Low Band: 40Hz to 1kHz (4.6 Octave) High Band: 600Hz to 15kHz (4.6 Octave) Q Controls These set the curve for boosting or cutting. Increasing the Q level will make sharper slope. (Refer to Fig. 2) wTTf Q ( = Intensity of Peak and Dip) can be figured out as shown right. 3dBLA/ n fo (Center Frequency) U_ Af (== fx—f2) Level Controls These set the amount of the boosting or cutting within the range from -15dB to +15dB. (Refer to Fig. 3) £ Frequency Response Changed by Q Control Frequency Response Changed by Level Control 3 ■ PANEL DESCRIPTIONS (FRONT PANEL) 0 EFFECT INDICATOR This lights up when the unit is in the equalizer mode. So you can easily see whether it is in the normal or equalizer mode. 0 EFFECT SWITCH Each time you push this switch, the unit turns to the equalizer or normal mode. 0 OVERLOAD INDICATOR When the level of the input signal is too high, this indicator lights up. O INPUT LEVEL KNOB This adjusts the level of the input signal. As you actually play the instrument, rotate this knob. Usually, this should be set to the highest possible level at which the Overload Indicator © does not light up. 0 FREQUENCY CONTROLS These select the frequency to be boosted or cut within the range as shown below. Low Band: 40Hz to 1kHz High Band: 600Hz to 15kHz 0 Q CONTROLS These set the curve for boosting or cutting. Raising this slider will make sharper slope. 0 LEVEL CONTROLS These set the amount of the boosting or cutting within the range from -15dB to +15dB. 0 TOTAL LEVEL CONTROL This can set the volume of the effect sound in the range of ±15dB, therefore serves to minimize the volume difference between the normal and the effect sounds. 0 OVERLOAD INDICATOR This indicator is usually lighted, but when the level of the output signal is too high in the Equalizer mode, this flashes. If this flashes, lower the Input Level Knob 0 or the Total Level Control 0. © POWER INDICATOR This indicator lights up when the unit is switched on ® POWER SWITCH (REAR PANEL) ® INPUT JACK (MIC) This is where a microphone is connected. ® INPUT JACK (INST) This is where an electric musical instrument such as an electric guitar is connected.
