The EQ Section
The 676 semi-parametric EQ provides a way to make broad tonal adjustments on the source. Of course it’s best to fix a tonal
issue at the mic by adjusting the mic placement, trying different mic polar patterns, or swapping the mic for another. However,
if you must make a mic work for the occasion and have already done all of these things then reaching for the EQ just may be
what’s needed. When tracking, it’s best used for subtle enhancements, such as adding a tinge of air to an acoustic guitar or
vocal, adding a little more definition to a bass, or helping remove some low-mid mud from distorted electric guitars.

1. Low Control [-15 dB to +15 dB]
This control adjusts the amount of low-frequency boost or cut. This is a shelving type filter with a fixed frequency of 100
Hz and a slope rate of 12 dB/octave.
2. EQ Enable Button
Press this button to enable/disable the EQ – the EQ is enabled when the button’s LED is lit.
3. High Control [-15 dB to +15 dB)]
This control adjusts the amount of high-frequency boost or cut. This is a shelving type filter with a fixed frequency of 10
kHz and a slope rate of 12 dB/octave.
4. Mid Control [-15 dB to +15 dB]
This control adjusts the amount of mid-frequency boost or cut. This is a peaking (bell) type filter.
5. Narrow Button
This button changes the ‘Q’ factor of the mid-frequency peaking filter. When the button is enabled (LED on), the filter
becomes more narrow and has a Q of 2.9. When disabled (LED off), the filter is wider and has a Q of 0.9.
6. Mid Freq [100 Hz - 8 kHz]
This control adjusts the center frequency of the mid-frequency peaking filter.
