Guided Tour - E62i / E31i / E30i Front Panel

1:Equalizer sliders - Independent Equalizer sliders are provided for each frequency area (theE62i’ and E31i provide 31 frequency areas, while the E30i’ provides 15). Calibration markings on either side of each Equalizer slider allow you to cut or boost each of frequency area. In the E62i and E30i, independent Equalizer sliders are provided for each of the two channels (Channel A and Channel B). As described below, the exact action of the Equalizer sliders depends upon the setting of the ±12 dB switch as well as, in the E62i and E31i, the setting of the Cut Only switch (see #4 and #7 on the next page).

In the E62i and E31i, when the Cut Only switch is not pressed in: When an Equalizer slider is at its center detented “0” position, the frequency area is unaffected (that is, there is no boost or cut). When moved all the way up (to the “+12 dB”) position, the frequency area is boosted by 12 dB (if the corresponding ±12 dB switch is pressed in) or 6 dB (if the corresponding ±12 dB switch is not pressed in). When moved all the way down (to the “-12 dB” position), the frequency area is attenuated by 12 dB (if the corresponding ±12 dB switch is pressed in) or 6 dB (if the corresponding ±12 dB switch is not pressed in).

In the E62i and E31i, when the Cut Only switch is pressed in: When an Equalizer slider is at its top-most position, the frequency area is unaffected (that is, there is no boost or cut), as indicated by the blue “0 dB” label. As the Equalizer slider is moved down, the frequency area is attenuated. As indicated by the blue “-6 dB” label, when the Equalizer slider is at its center detented position, the frequency area is attenuated by 6 dB (if the corresponding ±12 dB switch is not pressed in) or 12 dB (if the corresponding ±12 dB switch is pressed in). When moved all the way down (as indicated by the blue “-24 dB” label), the frequency area is attenuated by 12 dB (if the corresponding ±12 dB switch is not pressed in) or 24 dB (if the corresponding ±12 dB switch is pressed in).

In the E30i: When an Equalizer slider is at its center detented “0” position, the frequency area is unaffected (that is, there is no boost or cut). When moved all the way up (to the “+12 dB”) position, the frequency area is boosted by 12 dB. When moved all the way down (to the “-12 dB” position), the frequency area is attenuated by 12 dB.

2:Level sliders - Use these to adjust the output level of signal leaving the E62i / E31i / E30i via its rear-panel output connectors (see #2 and #3 on page 7 for more information). When a Level slider is at its center detented “0” position, the corresponding output signal is at unity gain (that is, there is no cut or boost). When a Level slider is moved all the way

up (to the “+6 dB”) position, the corresponding output signal is boosted by 6 dB. When a Level slider is moved all the way down (to the “∞ ” position), the corresponding output signal is infinitely attenuated (that is, there is no signal). In the E62i and E30i, independent Level sliders are provided for each of the two channels (Channel A and Channel B). Note that the Level slider is deactivated when the E62i / E31i / E30i is in Bypass mode (see #5 on the following page).

3:Peak LEDs - Light steadily red whenever the corresponding input signal is within 5 dB of clipping. During normal operation, the Peak LED(s) should light only infrequently or not at all. In the E62i and E30i, independent Peak LEDs are provided for each of the two channels (Channel A and Channel B).
