Universal Audio 2-610 Dual Channel - Manual (Page 9)

4
-15 dB PAD
Reduces the input signal by -15dB; Recommended in reducing the incoming signal in cases where
undesired distortion is present at low gain levels.
Polarity
The front panel toggle switch labeled IN ø and OUT ø determines the polarity of the LINE OUTPUT. When
IN ø is selected, pin 2 is hot (positive). When OUT ø is selected, pin 3 is hot (positive). Polarity reversal
may be useful in cases where more than one microphone is utilized in recording a source.
EQ Controls
The 2-610 has both low and high frequency shelving-type equalizers, each with two controls.
Frequency
This toggle switch selects the corner frequency for each of the filters. High: 4.5K, 7K, 10K; Low: 70,
100, 200.
Boost/Cut
This switch selects the amount of boost or cut applied to the frequency shelf. The positive and
negative numbers on the front panel denote dB values(-9, -6 -4.5, -3, 1.5, 0, 1.5, 3, 4.5, 6, 9).
+48 V
Most modern condenser microphones often require +48 phantom voltage to operate. Each channel of
the 2-610 has a toggle switch that applies 48 V to the MIC INPUT when the switch is up. It is good
practice to keep phantom power off (switch down) when it is not required. To avoid loud transients,
always keep phantom power off when connecting or disconnecting microphones. It is recommended
that the power requirements of your microphone be checked with the manufacturer before applying
phantom power.
