Meequalizer
The twinQ
"Meequalizer" is a highly effective, versatile and
2
musically rewarding three-band equalizer, or tone control
system. Each stage allows boost or cut of up to 15dB around the
frequency in question. The 'EQ' switch turns the equalizer on, and
the green LED lights when active.
The LF band can be tuned or "swept" anywhere between 40Hz
and 650Hz. It may help to think of it as like a graphic equalizer,
only instead of lots of frequency bands, you have just one, but it
can be moved to cover any given frequency band. Cutting low
frequencies can be used to reduce unwanted low frequency
noise, such as hum or rumble. Boosting can bring out the warmth
and body of bass lines and (especially around 80Hz) kick drums.
Higher up, cutting can reduce boominess or other annoying
resonances, while boosting can bring out the body and warmth of
a vocal, or the harmonics of bass instruments.
The MID band can be tuned or "swept" anywhere between 300Hz
and 5kHz. Cutting higher MID frequencies can reduce sibilance
or other annoying resonances. Boosting can bring out the
harmonics of instruments or make vocals more distinct.
Increasing or reducing the "presence" of an instrument or vocal in
this way, can appear to move the sound forwards or backwards in
a mix.
The HF or treble section is centred at either 6kHz or 12kHz.
Boosting the 12kHz band gives a sense of "air" or "sparkle" to
vocals, instruments and mixes, without boosting harsh upper-mid
frequencies. Alternatively with bass instruments, cutting this
band will reduce HF noise such as hiss and crackle. The 6kHz
setting is very effective at controlling sibilance and reducing
harshness, or indeed creating it, for example by boosting the
harmonics of electric guitars.
The EQ 'ON' switch allows comparison between equalized and
unequalized sound (LED lights when the Meequalizer is active).
The Meequalizer is after the Preamplifier, the Insert Point and the
Compressor.
Technical stuff
Each section of the Meequalizer has a peaking or "bell" shaped
frequency response, which will be found to be musically more
satisfying than conventional "shelving" equalizers. The use of bell
curves at LF and HF also avoids boosting subsonics and
ultrasonics which can have adverse effects on other studio
equipment, such as recorders, monitor amplifiers and speakers.
The "Q" value of the peaking filters is 0.9 (or 1.6 octaves). Zero
phase distortion ensures the best possible audio coherence.
