EQ
The UA 610 preamps feature high and low frequency boost/cut shelving fil-
ters with stepped gain controls. The equalizers utilize a feedback-style design
which effects the distortion characteristics of the output stage.
UA 610-A
The low frequency (“L.F.”) shelf EQ has a fixed cutoff frequency of
100 Hz.
Lo EQ Gain
This rotary switch determines the amount of boost or cut applied to the low fre-
quency signal. Fixed values of ±6 dB or 0 dB can be selected. When set to
0 dB, the filter is inactive.
UA 610-B
The low frequency (“LO”) shelf EQ has a selectable cutoff fre-
quency which can be cut or boosted by various amounts.
Lo EQ Frequency
This switch determines the cutoff frequency (70, 100, or 200
Hz) of the low shelf EQ. This switch has no effect if the Lo EQ
Gain value is zero.
Note: Like the hardware, low frequency values are not consecutively or-
dered.
Lo EQ Gain
This rotary switch determines the amount of boost or cut applied to the low fre-
quency signal. Fixed values of plus or minus 9, 6, 4.5, 3, or 1.5 dB can be
selected. When set to 0 dB, the filter is inactive.
High EQ UA 610-A
The high frequency (“H.F.”) shelf EQ has a fixed cutoff frequency of
10 kHz.
Hi EQ Gain
This rotary switch determines the amount of boost or cut applied to the high
frequency signal. Fixed values of –6, 0, +3, or +6 dB can be selected. When
set to 0 dB, the filter is inactive.
