X-Rack Stereo EQ Module
LMF Band controls:
Frequency Variable from 200Hz to 2.0kHz
Gain Variable by > ±20dB
‘Q’ Variable from 0.7 to 2.5 (may also vary with gain)
LF Band controls:
Frequency Variable from 40Hz to 600Hz
Gain Variable between ±20dB
‘Q’ 2.5 (on ‘ ’ setting)
The LF and HF bands have variable turnover frequency with switchable bell/shelving and selectable
response curves:
• Normal (‘E type’) curves – with the ‘G-EQ’
(‘ ’) switch OUT – follow conventional cut
or boost characteristics.
• The ‘G type’ curves – with the ‘G-EQ’ (‘ ’)
switch IN – have a modified slope which
provides a degree of overshoot/undershoot
for increased selectivity.
The two parametric bands have selectable characteristics which affect the relationship between frequency
bandwidth and gain:
• With the ‘G-EQ’ (‘ ’) switch OUT, the
frequency bandwidth is constant at all gains.
• When the ‘G-EQ’ (‘ ’) is switched IN, the
frequency bandwidth will reduce with
increased gain, thereby increasing the
selectivity of the EQ as the gain is increased.
• At full boost or cut both are identical.
